+
+ A New Subspecies of Lizard,
+ Cnemidophorus sacki, from Michoacán, México
+
+
+ BY
+
+ WILLIAM E. DUELLMAN
+
+
+The systematic status of the populations of lizards assignable to
+_Cnemidophorus sacki_ in western México (Sonora southward to Jalisco)
+has been reviewed in detail by Zweifel (1959, Bull. Amer. Mus. Nat.
+Hist, 117 (2):57-116), who stated that the use of the specific name
+_sacki_ for the western populations rests upon a reasonable, but as
+yet unproved, assumption that intergradation occurs. Although Zweifel
+examined specimens of the nominal subspecies from the upper Balsas
+Basin, he did not study specimens from the intervening area--the
+Tepalcatepec Valley in Michoacán.
+
+Field studies and the examination of large series of preserved
+specimens of _Cnemidophorus_ from the Tepalcatepec Valley show the
+presence of _Cnemidophorus sacki_ in the region between the ranges of
+_C. sacki sacki_ in the upper Balsas Basin and _C. sacki occidentalis_
+in Jalisco and southern Nayarit. Furthermore, the populations of
+_sacki_ inhabiting the Tepalcatepec Valley have characters of
+scutellation and coloration that distinguish them from other described
+subspecies of _sacki_. In recognition of the important contributions
+to the systematics of the genus _Cnemidophorus_ made by Dr. Richard G.
+Zweifel, I propose that the subspecies of _Cnemidophorus sacki_ in the
+Tepalcatepec Valley be named as follows:
+
+
+ +Cnemidophorus sacki zweifeli+ new subspecies
+
+_Holotype._--University of Michigan Museum of Zoology No. 119542, from
+Capirio, Michoacán, México (185 meters), an adult male, one of a
+series collected on June 13, 1958, by William E. Duellman, Jerome B.
+Tulecke, and John Wellman. Original number WED 12310.
+
+_Paratopotypes._--UMMZ Nos. 119536-119541 and 119543-119550.
+
+_Diagnosis._--A race of _Cnemidophorus sacki_ characterized by large
+size (more than 130 mm. snout-vent length in males), approximately 106
+dorsal granules around the midbody, about 41 femoral pores, and a
+dorsal color-pattern in adult males consisting of lateral and
+dorsolateral rows of spots, paravertebral rows fused with middorsal
+light green area at least anteriorly, and pink throat having a median
+light blue spot or transverse band.
+
+_Description of Holotype._--Snout-vent length, 128 mm.; tail length,
+252 mm.; tail/body ratio, 1.97; scutellation typical of _sacki_--four
+supraoculars, enlarged postantebrachials, and enlarged mesoptychials;
+107 granules around midbody (excluding enlarged ventrals); 45 femoral
+pores; three enlarged preanal scales; supraorbital semicircle-series
+extending anteriorly to posterior edge of frontal (Fig. 1).
+
+
+ [Illustration: Top View Head - Cnemidophorus sacki zweifeli]
+
+~Fig. 1.~ Top view of the head of the holotype of _Cnemidophorus sacki
+ zweifeli_ (UMMZ 119542) showing scutellation. ×5.
+
+
+Top of head and nape dusty brown; tip of rostral and lateral edges of
+superciliaries dark cream-color; upper labials and sides of head
+anterior to eyes cream-color, mottled with blue; lower labials and
+postocular region pale blue; mental, postmental, and sublabials
+cream-color. Upper surfaces of forelimbs dull bluish gray, spotted
+with pale greenish yellow; dorsal surfaces of proximal one-fourth of
+tail light brownish gray turning to pale orange-brown posteriorly;
+lateral surfaces of tail bluish gray anteriorly and creamy brown
+posteriorly. Nuchal region light bluish gray; flanks dark gray; dorsal
+ground-color dark brown, somewhat paler posteriorly. Body having a row
+of cream-colored spots in place of a lateral stripe, and another row
+in place of dorsolateral stripe; dorsally, large diffuse tan or light
+green spots partially fused and tending to form irregular transverse
+markings. Chin to posterior end of sublabials pale pink, bordered
+posteriorly by bluish white area, and then pink. Mesoptychials, under
+surfaces of hind limbs, and belly cream-colored; anterior edges of
+belly scales dark blue; lateral two rows of ventrals on posterior
+two-thirds of body dark blue having light blue or cream-colored spots.
+Under surfaces of forelimbs bluish cream; ventral surface of tail
+cream-colored.
+
+_Variation in Size and Scutellation._--The largest male has a
+snout-vent length of 132 mm., the largest female, 114 mm., and the
+smallest juvenile, 34 mm. The number of dorsal granules at the midbody
+varies from 91 to 117 (106.2 ± 0.43); the ratio of the number of
+granules between the paravertebral stripes to the number of granules
+around the body (PV/GAB) varies from 0.064 to 0.157 (0.097 ±0.007);
+the number of femoral pores varies from 32 to 49 (41.1 ± 0.20).
+Usually there are only three enlarged preanals, but 18 specimens have
+a somewhat enlarged scale anterior to the normal complement of three.
+In 15 specimens the supraorbital semicircle-series terminate short of
+the posterior edge of the frontal; in the others the series reach the
+frontal.
+
+_Variation in Coloration._--The coloration of juveniles and subadults
+varies little; large adults vary considerably especially in the amount
+of diffusion of the light green middorsal area. In some individuals
+the vertebral pale area does not include the paravertebral spots; in
+other individuals the pale area includes not only the paravertebral
+rows, but, at least anteriorly, the dorsolateral rows. In large males
+of about equal size (and collected at the same time) there is
+considerable variation in the amount of blue on the belly. In a few of
+the males the belly is white with only the anterior edge of each scale
+blue; in some only the lateral rows of ventrals on the posterior
+two-thirds of the body are blue; in others all of the posterior
+two-thirds of the belly is blue.
+
+_Ontogenetic Change in Color Pattern._--The metamorphosis of color
+pattern in _Cnemidophorus sacki zweifeli_ results in the dorsal
+ground-color becoming paler with age, the replacement of the stripes
+by spots, and finally in large males the suffusion of these spots.
+
+A single hatchling (UMMZ 114732) is available; this specimen has a
+prominent umbilical scar and a snout-vent length of 34 mm. The top of
+the head is olive brown; the dorsal surfaces of the limbs are dark
+brown with cream mottling; the dorsal ground-color is brownish black;
+this is paler on the lower flanks. The lateral and dorsolateral
+stripes are cream-colored; the paravertebral stripes are white. There
+is a faint, diffuse vertebral stripe anteriorly (Fig. 2 A). The throat
+and undersides of the limbs and tail are cream-colored; the belly is
+bluish white. In life the stripes were pale yellowish green, and the
+tip of the tail was pink.
+
+In larger individuals the dorsal ground-color is dark brown; the
+lower flanks are grayish tan. Light brown diffuse spots are present
+in the lateral and dorsolateral dark fields. The tan vertebral stripe
+is diffuse and nearly fills the paravertebral dark fields; the
+paravertebral stripes are faint posteriorly; throughout their length
+they are scalloped--the beginning of their fragmentation into spots
+(Fig. 2 B).
+
+In subadults (± 80 mm. snout-vent length) the paravertebral stripes
+are fragmented into spots posteriorly. Also, the dorsolateral stripes
+in some individuals are fragmented posteriorly. The dorsolateral dark
+fields are somewhat paler than the lateral dark fields. Cream-colored
+spots are present on the flanks. The mottling on the thighs tends
+towards the formation of light spots (Fig. 2 C).
+
+In small adults (± 100 mm. snout-vent length) the paravertebral
+stripes are entirely fragmented into spots. The lateral and
+dorsolateral stripes are broken into spots posteriorly. The middorsal
+pale area (formed by the suffusion of the vertebral stripe) and
+paravertebral and dorsolateral rows of spots are pale green. The
+cream-colored spots on the flanks are expanded to form vertical bars
+(Fig. 2 D).
+
+Large adult males (± 120 mm. snout-vent length) have all of the
+stripes fragmented into spots. The diffuse middorsal area is expanded
+and encloses the paravertebral rows of spots. The pale spots present
+in the dark fields in smaller individuals are either absent or fused
+with spots resulting from the fragmentation of the stripes (Fig. 2 E).
+
+_Sexual dimorphism._--Males attain a larger size (known maximum
+snout-vent length of 132 mm., as compared with 114 mm. in females).
+Males have larger but not more numerous, femoral pores, blue bellies,
+and pink and blue throats, whereas females are unicolor creamy white
+ventrally. The more nearly complete metamorphosis of color pattern
+exhibited by adult males probably is correlated with their large adult
+size. Large females retain complete lateral and dorsolateral stripes.
+The jowls of breeding males are swollen.
+
+

+
+~Fig. 2.~ Diagrammatic representation of ontogenetic change in color
+ pattern in _Cnemidophorus sacki zweifeli_: A--hatchling, 34 mm.
+ snout-vent length; B--juvenile, 55 mm. snout-vent length;
+ C--subadult male, 80 mm. snout-vent length; D--small adult male,
+ 100 mm. snout-vent length; E--large adult male, 120 mm. snout-vent
+ length.
+
+
+_Geographic variation._--No noticeable geographic variation in this
+subspecies is evident in the series from the Tepalcatepec Valley.
+However, lizards from eastern Michoacán (Chinapa, 6 km. N of Tafetan,
+6 km. S of Tzitzio, and 19 km. S of Tzitzio) differ slightly from
+those from the Tepalcatepec Valley; the eastern specimens have fewer
+dorsal granules and femoral pores, and a higher ratio of dorsal
+granules between the paravertebral stripes to the number of granules
+around the body (see Tables 1-3). No large adult males are present in
+the eastern series; the subadults and small adult males have color
+patterns like lizards of similar size from the Tepalcatepec Valley.
+The largest male from the east has a snout-vent length of 110 mm.,
+rows of pale spots, and no trace of brown and tan cross-bars.
+Specimens of _Cnemidophorus sacki sacki_ of equal size from Guerrero,
+Morelos, and Puebla in the upper Balsas Basin have a tan dorsum with
+dark brown cross-bars. The localities in eastern Michoacán are
+intermediate geographically between the Tepalcatepec Valley and the
+known range of the nominal subspecies in the upper Balsas Basin. In
+characters of scutellation specimens from the east are intermediate
+between _C. sacki sacki_ and _C. sacki zweifeli_ in the Tepalcatepec
+Valley. However, in coloration the lizards from the east are like
+those from the Tepalcatepec Valley, but differ distinctly from the
+nominal subspecies. Therefore, the eastern series is referred to the
+subspecies _C. sacki zweifeli_.
+
+_Comparisons._--Four other species of _Cnemidophorus_ occur in the
+Tepalcatepec Valley with _Cnemidophorus sacki zweifeli_. Of these, _C.
+calidipes_ has a maximum snout-vent length of 79 mm., 66 to 86 dorsal
+granules, and a light brown dorsum with pale blue spots and vertical
+bars; _C. communis communis_ has a maximum snout-vent length of 135
+mm., 105 to 144 dorsal granules, and a greenish tan dorsum with yellow
+spots; _C. deppei infernalis_ has a maximum snout-vent length of 84
+mm., 91 to 120 dorsal granules, and a striped pattern throughout life;
+and _C. lineatissimus exoristus_ has a maximum snout-vent length of 98
+mm., 108 to 135 dorsal granules, and a middorsal yellow stripe and
+vertical bars on the flanks. Both _calidipes_ and _communis_ are like
+_sacki_ in possessing four enlarged supraoculars and enlarged
+postantebrachials, whereas _deppei_ and _lineatissimus_ have three
+enlarged supraoculars and granular postantebrachials. Juveniles of
+_calidipes_ and _sacki_ are alike in coloration but different in the
+extent of the supraorbital semicircle-series. In _calidipes_ the
+supraorbital semicircle-series usually are complete, whereas in
+_sacki_ the series never extended anterior to the posterior edge of
+the frontal.

+
+
+
+
+From the geographically adjacent populations of _sacki_ (_sacki_ and
+_occidentalis_), _zweifeli_ differs in coloration and scutellation
+(see Tables I-III). _Cnemidophorus sacki sacki_ has a dorsal pattern
+in adult males of dark brown cross-bars on a tan ground-color. Both
+_occidentalis_ and _zweifeli_ have variable, diffuse color patterns
+in large adults, but _zweifeli_ differs from _occidentalis_ in having
+a blue spot on the pink throat.
+
+_Ecology._--In the arid Tepalcatepec Valley _Cnemidophorus sacki
+zweifeli_ lives at elevations of 160 to 1300 meters. In the lower
+parts of the valley the lizards live primarily in open scrub forests,
+characterized by deciduous trees offering only partial shade from the
+sun, especially during the prolonged dry season. Common trees in
+this scrub forest are _Acacia cymbispina_, _Cercidium
+plurifoliolatum_, _Mimosa distachya_, and _Prosopis juliflora_.
+
+During the dry season (November through May) adult males apparently
+aestivate; several large series collected in the winter include only
+subadults and females. This absence of males is corroborated by
+personal observations in the Tepalcatepec Valley in April and May. In
+the summer rainy season the lizards are active in the morning and
+again in the late afternoon; only _Cnemidophorus calidipes_ is active
+during the heat of the midday. In some areas of the scrub forest
+_Cnemidophorus sacki zweifeli_ is found in association with
+_Cnemidophorus communis communis_. Throughout the scrub forest _C.
+sacki zweifeli_ occurs with _C. deppei infernalis_. In some of the
+more dense scrub forest, where _C. sacki zweifeli_ is not so abundant
+as in the more open forest, it has been taken with _C. lineatissimus
+exoristus_. In the open _Acacia-Cercidium_ associations on the valley
+floor _C. sacki zweifeli_ occurs with _C. calidipes_.
+
+This subspecies is not restricted to the scrub forest. On the lower
+slopes of the Cordillera Volcanica in Michoacán _C. sacki zweifeli_
+has been collected in open pine-oak forest near Zirimicuaro and
+Ziracuaretiro.
+
+_Distribution._--_Cnemidophorus sacki zweifeli_ inhabits the valley
+of the Río Tepalcatepec in Michoacán and probably extreme southwestern
+Jalisco, and the western part of the Balsas Basin in Michoacán. No
+specimens have been seen from extreme western Guerrero, but _C. s.
+zweifeli_ may occur there.

+of the name of the institution as listed in the acknowledgements.

+set forth in the General Terms of Use part of this license, apply to
+copying and distributing Project Gutenberg-tm electronic works to
+protect the PROJECT GUTENBERG-tm concept and trademark. Project
+Gutenberg is a registered trademark, and may not be used if you
+charge for the eBooks, unless you receive specific permission. If you
+do not charge anything for copies of this eBook, complying with the
+rules is very easy. You may use this eBook for nearly any purpose
+such as creation of derivative works, reports, performances and
+research. They may be modified and printed and given away--you may do

+PLEASE READ THIS BEFORE YOU DISTRIBUTE OR USE THIS WORK
+
+To protect the Project Gutenberg-tm mission of promoting the free
+distribution of electronic works, by using or distributing this work
+(or any other work associated in any way with the phrase "Project
+Gutenberg"), you agree to comply with all the terms of the Full Project
+Gutenberg-tm License (available with this file or online at

+
+
+Section 1. General Terms of Use and Redistributing Project Gutenberg-tm
+electronic works
+
+1.A. By reading or using any part of this Project Gutenberg-tm
+electronic work, you indicate that you have read, understand, agree to
+and accept all the terms of this license and intellectual property
+(trademark/copyright) agreement. If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or destroy
+all copies of Project Gutenberg-tm electronic works in your possession.
+If you paid a fee for obtaining a copy of or access to a Project
+Gutenberg-tm electronic work and you do not agree to be bound by the
+terms of this agreement, you may obtain a refund from the person or
+entity to whom you paid the fee as set forth in paragraph 1.E.8.
+
+1.B. "Project Gutenberg" is a registered trademark. It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement. There are a few
+things that you can do with most Project Gutenberg-tm electronic works
+even without complying with the full terms of this agreement. See
+paragraph 1.C below. There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works. See paragraph 1.E below.
+
+1.C. The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works. Nearly all the individual works in the
+collection are in the public domain in the United States. If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work. You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are in
+a constant state of change. If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work. The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E. Unless you have removed all references to Project Gutenberg:
+
+1.E.1. The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently
+whenever any copy of a Project Gutenberg-tm work (any work on which the

+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+
+This eBook is for the use of anyone anywhere at no cost and with
+almost no restrictions whatsoever. You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included
+with this eBook or online at www.gutenberg.org
+
+1.E.2. If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges. If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
+1.E.9.
+
+1.E.3. If an individual Project Gutenberg-tm electronic work is posted
+with the permission of the copyright holder, your use and distribution
+must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
+terms imposed by the copyright holder. Additional terms will be linked
+to the Project Gutenberg-tm License for all works posted with the
+permission of the copyright holder found at the beginning of this work.
+
+1.E.4. Do not unlink or detach or remove the full Project Gutenberg-tm
+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.
+
+1.E.5. Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6. You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form. However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+"Plain Vanilla ASCII" or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form. Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.
+
+1.E.7. Do not charge a fee for access to, viewing, displaying,
+performing, copying or distributing any Project Gutenberg-tm works
+unless you comply with paragraph 1.E.8 or 1.E.9.

+ has agreed to donate royalties under this paragraph to the
+ Project Gutenberg Literary Archive Foundation. Royalty payments
+ must be paid within 60 days following each date on which you
+ prepare (or are legally required to prepare) your periodic tax
+ returns. Royalty payments should be clearly marked as such and
+ sent to the Project Gutenberg Literary Archive Foundation at the

+ the Project Gutenberg Literary Archive Foundation."
+
+- You provide a full refund of any money paid by a user who notifies
+ you in writing (or by e-mail) within 30 days of receipt that s/he
+ does not agree to the terms of the full Project Gutenberg-tm
+ License. You must require such a user to return or
+ destroy all copies of the works possessed in a physical medium
+ and discontinue all use of and all access to other copies of
+ Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+ money paid for a work or a replacement copy, if a defect in the

+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can

+received the work on a physical medium, you must return the medium with
+your written explanation. The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund. If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund. If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4. Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO

+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law. The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,

+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation

+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.

+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
