A SYSTEMATIC REVIEW OF AMEIVA AUBERI COCTEAU (REPTILIA, TEIIDAE) IN CUBA AND THE BAHAMAS 1. THE CUBAN SUBSPECIES Albert Schwartz^ Research Associate, Section of Amphibians and Reptiles Carnegie Museum, Pittsburgh, Pennsylvania The ground lizard Ameiva auberi Cocteau, of Cuba and the Isla de Pinos, was described in 1838 or 1839 (Smith and Grant, 1958)^ in Ra- mon de la Sagra's monumental ''Historia fisica, politica y natural de la Isla de Cuba.” Until Hecht (1954) considered the Bahamian Ameiva thoracica Cope as conspecific with the Cuban species, the latter was regarded as monotypic. The last revisers of the genus Ameiva (Bar- bour and Noble, 1915) had little material of A. auberi (only fifteen specimens from widely scattered localitites on both Cuba and the Isla de Pinos, in no case more than five specimens from any single locality ) so that it is not surprising that intraisland variation in A. auberi went unnoted. In fact, other than the recent collections made by myself and parties between 1957 and 1960, there is remarkably little material of A. auberi in American museums. It is the purpose of the present paper to discuss the variation in A. auberi and to comment on the history and affinities of the species. I have had available for study 668 Ameiva auberi specimens col- lected by myself and assistants in Cuba and the Isla de Pinos under the sponsorship of National Science Foundation grants G-3865 and G-6252. These specimens have all been deposited in the American Museum of Natural History (AMNH). I have also studied lizards in the Carnegie Museum (CM); the Museum of Natural History, Univer- sity of Kansas (KU); the Museum of Comparative Zoology, (MCZ); the Museum National d’Historie Naturelle (MNHN); the University of Florida/Florida State Museum (UF); the University of Illinois Muse- um of Natural History (UIMNH); the Museum of Zoology, University 1.

Issued September 18, 1970 45 SMITHSONIA' 46 Annals of Carnegie Museum VoL. 41 of Michigan (UMMZ); and the United States National Museum (USNM). For the loans of these lizards I wish to thank Charles M. Bogert and George W. Foley, Neil D. Richmond and Clarence J. McCoy, Jr., William E. Duellman, Ernest E. Williams, Jean Gnibe, Walter Auffenberg and Lewis D. Ober, Hobart M. Smith, the late Norman E. Hartweg, Charles F. Walker and Dale Hoyt, the late Doris M. Cochran and James A. Peters. The large quantity of fresh material available to me has been invaluable. These new and carefully docu- mented specimens have aceumulated through the efforts of several eapable and interested field companions, namely: Edwin B. Eriekson, John R. Feick, William H. Gehrmann, Jr., Robert S. Howard, Ronald F. Klinikowski, David C. Leber, Dennis R. Paulson, Peter F. Pepe, Donald R. Price' Frank C. Sentz, Jr., James D. Smallwood, Barton L. Smith, Willard M. Stitzell, James R. Talada, Richard Thomas, and George R. Zug. Of these men, Messrs. Klinikowski and Leber were recipients of National Seienee Foundation Undergraduate Research Participation grants in 1959 and 1960. I wish especially to acknowledge the help of Armando Gareia and Porfirio Azeuy in western Cuba. Spee- imens of A. aiiheri from eastern Cuba colleeted by Major Chapman Grant and in the UIMNH were under study by Dr. Hobart M. Smith. He relinquished his interest in these lizards, and for this eourtesy 1 am very grateful. In addition to examining specimens in Ameriean eollections, 1 have been able, through the courtesy and cooperation of Hector Sague D. and Orlando H. Garrido, to examine the excellent collections of A. auheri made throughout Cuba by Sr. Garrido for the Institute de Biologia, Academia de Ciencias de Guba ( IB ) . Also, Sr. Garrido made available to me his notes on color and pattern, as well as eolor slides of many of the speeimens he had collected, and they have proved inval- uable. Through the kindness of Mario S. Buide I have been able to study a fine series of Ameiva from southern Las Villas Province. Some of these specimens are in Sr. Buide’s collection (MSB) and the remain- der are in the Albert Schwartz Field Series (ASFS) and in the Na- tional Musuem of Canada (NMC). Some lizards, originally in the IB collection, have also been deposited in the ASFS, the CM, and the NMC. A total of 1067 specimens of Ameiva auheri is available to me. Scale eounts were taken by William H. Gehrmann, Jr. on several lots of material collected in 1957 and 1958. Indeed the present paper at its inception was to be a joint effort between Mr. Gehrmann and myself, but other duties prevented him from continuing with the study. I am 1970 Ameiva auberi: I. The Cuban Subspecies 47 grateful for his early assistance in compiling data and for allowing me to use his counts. Ameiva auberi is widespread on Cuba and the Isla de Pinos. The lizard occurs also on many of the offshore keys, including the Laberinto de las Doce Leguas off the south coast of Camagiiey Province and the Archipielago de los Canarreos off Punta del Este of the Isla de Pinos. A. auberi is not purely coastal in distribution, occurring in the interior of all Cuban provinces and throughout the the Isla de Pinos. It does not occupy areas that are either extremely mesic or moderately to extremely high. Substrates are usually sandy or rocky ( diente de perro limestone for example), but gravelly soils (like the Malpais gravel on the Isla de Pinos or the gravelly serpentine savannas of Camagiiey Province) are occupied in some regions. In the areas near Soledad, Las Villas Prov- ince, and near San Miguel de los Banos in Matanzas Province, A. auberi occurs in old abandoned earthen fields that have none of the characters specified above. Nowhere is A. auberi known to occur in the mountains except in the Sierra de los Organos-Sierra del Rosario massif in Pinar del Rio Prov- ince, unless the occurrence of the species near Palma Soriano in Oriente Province is interpreted as being within the Sierra Maestra ( if so inter- preted, the elevation is low — about 1000 feet — and hardly to be con- strued as within the high uplands of this range), and at La Poa in the Cuchillas de Toa. In the Sierra de los Organos, the lizards occur in cul- tivated areas and in rather arid upland ( 1000 feet and slightly higher ) woods on well-drained and gravelly soils. In this region, A. auberi is not associated with the luxuriant forests on the mogote sides and sum- mits, but rather with valley floors and drier woods. Certainly the habitats occupied by the largest number of A. auberi are coastal, including offshore cays and islands. In such areas, the liz- ards occur in beach growth of seagrape and coconuts, in coastal scrub, and xeric coastal woodlands. On some of the cays A. auberi occurs on open and hard-packed sandy soils which, in the heat of midsummer, become uncomfortably hot for the collector at midday. Inspection of the map (Fig. 1) shows that although A. auberi occurs virtually from one end of Cuba to the other, there are large areas where these lizards have not been collected. Much of the area whence A. auberi is unknown is forested uplands, but some of it is also apparently suitable for occupation by these lizards. The hiatuses may well be the result of lack of collecting in some instances, but in others the lizards simply appear to be absent. For instance, despite several weeks collect- 48 Annals of Carnegie Museum VoL. 41 ing over the years in southern and central Camagiiey Province, no Ameiva aiiberi were secured in apparently suitable situations there. Visits to the head of the Bahia de Cochinos in Las Villas Province re- vealed no lizards in an area of open beach and dry lowland woods — habitats which in southern Oriente would have been aswarm with Ameiva. Such incidents, the list of which might be much expanded, in- dicate that the apparently spotty distribution of A. aiil)eri may well be more real than a glance at the map reveals. I have collected or studied as-yet-unpreserved specimens of all sub- species except three, and have extensive notes on coloration and pat- tern in life. Such information is absolutely esssential when studying liz- ards whose coloration is fugitive in preservative and whose pattern may be obliterated by prolonged periods in formalin or alcohol. Bor- rowed material in most cases has served merely to confirm the exist- ence of these lizards in the general regions where I have taken them, and to confirm as well the differences between subspecies in life. The excellent recent collections in the Institute de Biologia, Academia de Ciencias, La Habana, made by Sr. Garrido, have revealed the presence of Ameiva in three other areas. In only one instance ( a single example from the Sierra de Jatibonico, Las \hllas Province) have I examined an old specimen from an area which is not represented in fresh collec- tions, and of course the treatment of this one individual has been ex- tremely tentative. The racial status of A. auheri from two other areas (extreme northeastern Pinar del Rio Province; north coast of Camagiiey Province north of the Sierra de Cubitas), despite fresh material from both areas, has been left in abeyance. These cases will be discussed in the text. Nomenclatorial History Smith and Grant (1958) discussed the authorship of the names pro- work was published in both Spanish and French editions. The Spanish posed by Cocteau and Bibron in de la Sagra’s “Historia . . . de Cuba.” The edition, which was the earlier published, in twelve folio volumes, con- tains the description of Ameiva auheri in volume 4. Volume 4 of both Spanish and French editions was also published in two parts. From the evidence presented by Smith and Grant, part I of volume 4 of the Span- ish edition antedates its homologue in the French edition, the former appearing in 1838 or 1839, and die latter by 1841. As far as authorship is concerned. Smith and Grant ( p. 216 ) stated that Cocteau was the sole author of all material before page 120 of part I of volume 4 of both edi- tions, and that all names after page 120 are to be attributed jointly to 1970 Ameiva auberi: I. The Cuban Subspecies 49 Cocteau and Bibron. Since the original description of Ameiva auberi is on page 51 of the ( earlier ) Spanish edition, the name is presumably to be attributed solely to Cocteau. Additional evidence that A. auberi was de- scribed only by Cocteau is that the name is followed, at its original place of proposal, by the name of Cocteau only, whereas later names (i.e., Epierates angulifer and Dromicus angulifer) are followed by “nobis,” thereby suggesting joint authorship. Although the evidenee is not com- pletely incontrovertible, it seems appropriate to eonsider that Coeteau was the author of Ameiva auberi. One other name has been proposed for Cuban Ameiva: Ameiva tri- lineata Gray, 1845. This name was based upon four syntypes in the British Museum (Natural History) colleeted by W. S. Maeleay. Pertinent color data included in the original description are that the species is “olive, with three pale streaks,” and that the tail has a “white streak on each side.” Gray, although also listing Ameiva auberi Cocteau, had obviously not examined material of the latter form and was surely unaware that his A. trilineata demonstrated a pattern that is commonplace in juve- niles and subadults of several populations of A. auberi, and that also per- sists into the adults of some races. Maeleay {fide Conde, 1958b: 261) lived in Cuba from 1827 to 1836, residing at Guanabacoa to the east of La Habana in Habana Provinee. Presumably the syntypes of A. trilineata were secured in the region near Guanabacoa. In this region at least juvenile and subadult lizards have a trilineate pattern. Consequently I regard Ameiva trilineata Gray a strict synonym of Ameiva auberi Cocteau. The monotypic status of Amiva auberi was maintained until Hecht (1954:133), in discussing the Bahamian fauna, used the eombination Ameiva atd)eri thoraciea Cope for the ground lizards of these islands. The similarities between A. auberi and A. thoraciea are obvious upon casual inspection; in fact, Sutcliffe (1952:5) identified as A. thoraciea a ground lizard from Cayo Largo, of the Archipielago de los Canarreos off the eastern tip of the Isla de Pinos. This identification was made on the basis of agreement in lepidosis and coloration of the Cayo I.argo speci- men with Barbour and Noble’s diagnosis of A. thoraciea, in eontrast to their diagnosis of A. auberi. Although 1 have not examined this partic- ular individual, a series of these lizards from Cayo Largo shows that they indeed represent a distinetive subspecies of A. auberi. The point here, however, is that auberi and thoraciea are very close in both pattern and sealation details, and I have no doubt that they are eorreetly consid- ered as conspecific. In the present paper I have made no effort to com- 50 Annals of Carnegie Museum VoL. 41 pare the Cuban and Bahamian subspecies of A. auberi since the Baha- mian lizards are under study by Clarence J. McCoy (see part II of this article). I have examined fairly extensive material from various Baha- mian islands and am aware of the variation in both pattern and scalation of these lizards in the Bahamas. Cocteau (1838 or 1839:54) discussed the coloration of the material before him at the time of the description of A. auberi. It is obvious that he had more than a single specimen since he contrasted the juvenile with the adult coloration. The former was stated as being a deep-colored green above with five (median dorsal, two dorsolateral, two lateral) whitish or yellowish lines. The lateral fields (between the dorsolater- al and lateral pale lines ) are dark brown. In adults, the lines disappear and the general dorsal coloration becomes a more or less dull ashy green. The coloration of the sides is changed into lenticular black spots, which form a not particularly clear, undulating black longitudinal band (the lateral fields). The ventral surfaces in the adult are greenish yellow. The figure of Ameiva auberi in the Atlas of the de la Sagra work shows a dorsally unlined lizard with the back grayish green, lateral fields bounded above and below by dirty white lines, scattered large black blotches in a grayish tan lateral field, a gray belly, and a greenish-gray throat. No population of A. auberi with which I am familiar is characterized by the above combination of color and pattern. Since it is mandatory to restrict the type locality of A. aul)eri Cocteau, I have corresponded with Jean Guibe of the Museum National d’His- toire Naturelle, in which it might be assumed the original material of A. auberi is deposited. In response to my query. Dr. Guibe replied that there are four specimens (MNHN 1112, 2647, 1788, and 4178) that came from Guba and were given to the collection by Ramon de la Sagra. These four lizards are considered in the eatalogue to be the syntypes of A. auberi. However, none of them corresponds with the measurements given by Gocteau (1838 or 1839:51). Cocteau’s most pertinent mea- surements are a total length of 260 mm. and a tail of 170 mm., giving a snout-vent length of 90 mm. Dr. Cuibe further stated that MNHN 4178 is probably the specimen later described in detail by Dumeril and Bibron (1839:111 et seq.), but as noted above, it does not agree with the data given by Coeteau. The problem thus resolves itself into the precise status of these four specimens. The evidence for their being syntypes seems ineonclusive. Since none of the four lizards agrees in dimensions or in pattern with Coeteau’s detailed data, plate, and description, and since often in that 1970 Ameiva auberi: I. The Cuban Subspecies 51 period of zoological research the ultimate importance of typical material was unrecognized — with the result that the designation of these four lizards as syntypes may have been made much later than the appearance of both the de la Sagra and Dumeril and Bibron works — I have disre- garded these four lizards (of which I have examined MNHN 1788 and 2647) as indicators of the provenance of the specimens on which the name A. auberi was based. The situation is thus anomalous. The “syntypes” themselves do not agree with the details as given by Cocteau, and the Cocteau description and plate do not agree with any known population of A. auberi. How- ever, the following comments are pertinent. Cocteau (1838 or 1839:51) stated that Ameiva auberi was named for Don Pedro Auber of the Jardin botanico de la Habana. Since these lizards even now are moderately abundant in the La Habana region, it would seem not improbable that Auber collected the original specimens in this general area. The two Paris specimens that 1 have examined do not agree in any way with La Habana material but do agree in scale counts, coloration, and pattern with recent material from the southern third of the Isla de Pinos. Conde (1958a:78) stated that among many other contributors to de la Sagra’s work was A. H. Lanier (the French consul at Trinidad, Cuba), who explored the Isla de Pinos in 1831 (Jen- nings, 1917:22). Since Lanier made a collection of plants for de la Sagra on the Isla de Pinos it is not improbable that he may have collected a few other natural-history specimens there also. Thus, the two Paris specimens I examined may well have come from the Lanier collections from Isla de Pinos, but there is no assurance that these two (or the remaining two ) were before Cocteau when he named Ameiva auberi. Everything considered, I have placed most emphasis on two facts stated by Cocteau : ( 1 ) that the species was named for Auber, who re- sided in La Habana, and ( 2 ) that no mention was made of a black throat on any of the syntypes, especially the large individual for which meas- ments and detailed description were given. Since the recently taken ma- erial from Habana Province lacks a black throat ( a very striking feature where it occurs ) , in at least this one feature the fresh material resembles Cocteau’s description. I therefore restrict the type locality of Ameiva auberi to the vicinity of La Habana, Habana Province, Cuba. If, in the future, the status of the supposed syntypes can somehow be established without doubt, and they ( or some of them ) are considered to have orig- inated on the southern portion of the Isla de Pinos, a nomenclatorial shift alone will be required. The northern coastal population in Habana Pro- 52 Annals of Carnegie Museum VoL. 41 vince will require a new name, and the name I have proposed in the pres- ent paper for the southern Isla de Pinos population will become A. a. auberi. With the above restriction, the population of Ameiva auberi in north- ern Habana and Matanzas provinces becomes the nominate race. Al- though heretofore I have begun the systematic treatment of Ameiva ( from Hispaniola ) with a discussion of the nominate form, I depart from this more logical procedure here. It seems preferable in this case to be- gin the discussions of the various subspecies with that of the race at the extreme western end of the island and proceed eastward. Such a method permits the placement of A. a. auberi in its proper geographic position relative to the subspecies to the east and west. Ameiva auberi may be defined as follows (data from both Cuban and Bahamian populations combined): Characteristics and Variation ( 1 ) a moderate-to-large species of the genus Ameiva with snout-vent length to 136 mm. in males and 115 mm. in females; (2) dorsal caudal scales keeled and straight; ( 3 ) ventrals in 8 to 14 transverse rows ( although the modal count is overwhelmingly 10, and counts of 8, 9, 11, 12, and 14 occur rarely and never characteristically in any subspecies) and in 28 to 36 longitudinal rows; (4) fourth toe subdigital scales from 61 to 94 — combined counts for both fourth toes; (5) femoral pores 20 to 35 — both series combined; (6) fifteenth caudal verticil with 22 to 37 scales; (7) dorsal pattern variable but consisting of either (a) a median and two dorsolateral pale lines enclosing between them the dorsal fields, which are some shade of brown, varying from pale-sandy or tannish gray to brown or rich reddish brown, or ( b ) more or less unicolor tans to browns dorsally without (or only faintly indicated) median and dorsolateral lines, and having the lateral fields black or brown, with varying amounts and patterns of red, brick-red, tan, or brown included in the lateral fields; (8) throat varying from cream or yellow to solid black, the black often extending posteriorly onto the abdomen for various distances; and (9) hemipenis extending to about the sixth to eighth caudal verticil, sulcate surface naked, sulcus bifurcating apically, the branches ending in two poorly defined apical discs, non-sulcate surface entirely flounced, the flounces extending to the margins of the sulcate surface, a small smooth triangular area on the non-sulcate side dividing the flounces for about one third the length of the organ into two fields of flounces which correspond to the apical discs. In the following subspecies accounts, data have been given on size, rows of transverse and longitudinal ventrals, total number of fourth-toe scales, total number of femoral pores, scales in the fifteenth caudal ver- ticil, and coloration and pattern. Emphasis has been placed on the last categories, and on size ( snout-vent length ) . The meristic data from scale counts, although showing means which are often statistically significant inter se (see Table 4), offer no sure way of identifying any individual 1970 Ameiva auberi: I. The Cuban Subspecies 53 Specimen, but on the other hand offer differences between various pop- ulations. It should be recognized from the beginning of the accounts that such rankings as “high,” ‘moderate,” and “low” in regard to fourth-toe scales, femoral pores, and fifteenth verticil scales are arbitrary rankings according to the means of these counts. However, such scale characters are an additional way of quantifying the interpopulation differences and are moderately useful in defining subspecies. The remarkable consistency in counts of longitudinal and transverse rows of ventrals renders them of no value in differentiating the subspe- cies. Despite transverse counts of 8, 9, 11, 12, and 14, the modal con- dition in all populations is very strongly 10 (see, however, the account of the subspecies from the northern Las Villas caijeria) . The modal number of longitudinal rows of ventrals in all Cuban subspecies varies from 31 to 34. The modal condition in any population is not significant (with the exception that only one Cuban population has a mode of 31 and only two have modes of 34 ) , since the range of variation in any giv- en sample almost matches the entire range for this character ( 28 to 36 ) in all Cuban specimens studied. For example, in a sample of 85 speci- mens from between the Bahia de Santiago and the Bahia de Guantana- mo, the range of longitudinal rows of ventrals is 30 to 36, and the sample of 57 specimens from the northern portion of the Isla de Pinos has longi- tudinal counts of from 29 to 34. In the former instance, the mode is 32, in the latter 31. It is obvious that this count is hardly valuable for diag- noses, but data are nevertheless presented in each subspecies account. Attention should be directed to the throat coloration. Ten Cuban pop- ulations from ( at times ) widely separated regions are characterized by having black throats. In most cases, the black throat and chest color are fairly constant within a sample from a particular region. Males have the throat and chest black ( although in two of the black-throated popula- tions — near Trinidad in Las Villas, and in northern Matanzas — the throat is not completely black but has a black median blotch ) . Although it would be reassuring to be able in the case of these black-throated sub- species to state that “all adult males above a snout-vent length of such- and-such have black throats,” such a statement is seldom completely true. In most cases some large and obviously adult males lack any indi- cation of a black throat and chest, and this character may also appear randomly in smaller males far below the maximally sized individuals. Very rarely do females of these black-throated races have the throats I as completely black as do the black- throated males. Throats of females resemble in intensity of pigment those of adult males that are just acquir- 54 Annals of Carnegie Museum VoL. 41 ing the fully black throat and chest. Small subadults and juveniles of both sexes lack any indication of black throats. The details of the con- dition of black throats in each sex in those subspecies that are black- throated are discussed individually in each account. The above qualifica- tions should be understood in advance. In several populations ( northern Oriente coast at Gibara, Cayo Can- tiles in the Archipielago de los Canarreos, Cayuelo de la Vela in the Archipielago de Sabana off the northern coast of Las Villas) there are some peculiarities of throat pigmentation: at Gibara, there apparently occurs a non-black-throated population of a subspecies that elsewhere along this coast is black-throated, whereas in the two island chains of the Archipielago de los Canarreos and Sabana, individual islands have black-throated populations or occasional black-throated lizards in oth- erwise non-black-throated areas. My treatment of these three anoma- lous instances has been arbitrary, primarily because in two cases (Gi- bara, Cayo Cantiles) I have seen little or no living material. In these two instances I have included the peculiarly colored lizards with their adjacent relatives, but this treatment is not necessarily correct. In the third case (Cayuelo de la Vela), I have chosen to distinguish the pop- ulation there nomenclatorially. In each instance I have given my rea- sons for the course I have pursued. I have not mentioned here the sit- uation on the southern portion of the Isla de Pinos, wherein the popula- tion may or may not have black throats, although there, if the throat is not black, that color is not replaced by red or orange, but is merely pale blue. Details of the southern Isla de Pinos lizards will be discussed later. Aside from the anomalous populations mentioned above, all those subspecies that have the throat colored (in contrast to black) have it so regularly, without exception (subadults and females may have the throats somewhat paler than adult males ) . Thus, in over 60 specimens of the widespread race in Pinar del Rio, the throat in all is uniformly yellow, and no specimen shows any indication of black pigment. From these circumstances, I deduce that some populations have the potential for ontogenetic development of black throats, whereas others lack it completely. This basic assumption has brought about the description of colored- and black-throated races that at times closely approximate each other geographically, and that at times also have relatively re- stricted distributions. Comments will be made in the appropriate places on such situations. Recent workers on the related teiid genus Cnemidophorus have employed the number of dorsal granules at midbody as a character 1970 Ameiva auberi; I. The Cuban Subspecies 55 useful for differentiation of species, and, to a more limited degree, of subspecies. Although in my previous studies on West Indian Ameiva, I have not used this count, in an effort possibly to give added data on subspecific differentiation in A. auberi, a set of pilot counts was taken on specimens from the two exti'emes of Cuba — Cabo de San Antonio and east of Guantanamo — plus specimens from the southern coast of Pinar del Rio. The midbody granules vary from 89 to 112 in the lot counted. The series from Cabo San Antonio and east of Guantanamo have virtually identical extremes (91 to 112), whereas the lower counts (89 to 98) are from southern Pinar del Rio. These data suggest that, as in Cnemidophortis, some subspecies of A. auberi might be partially de- finable on the basis of number of dorsal granules, but just as in other counts in this species, the dorsal granule differences are by no means absolute. Maximum size of the various subspecies of A. aul)eri shows some striking differences. Sometimes there has been comment on the validity of using this character to differentiate races of teiid lizards, the premise being that the collector may simply not encounter fully adult speci- mens in the course of his activities. 1 feel strongly that such an assump- tion is incorrect. The very large size of specimens of A. aid)eri from Pinar del Rio Province, for instance, whence long series are available, stands in contrast to the much smaller maximum size of a large number of specimens from southern Oriente between the Bahia de Santiago and the Bahia de Guantanamo. In the former region, males reach a snout-vent length of 136 mm. ( with many males with snout-vent lengths in excess of 100 mm.), whereas in the latter region no male reaches a snout- vent length greater than 78 mm. Such differences hardly seem attributable to artifacts of collecting and sampling. To me the differ- ences represent inherent genetic differences in size (and bulk) of the members of the populations involved. In none of the five large sub- species (one in Pinar del Rio, two in northern Las Villas, two in south- ern Las Villas) exceeding 100 mm. snout-vent length in maximum size, are males represented by a single unusually large or “giant” male and a larger suite of much smaller males. In all cases there is graded series from small to very large males, with the largest specimen merely the end of a long and evenly graded series of males of increasing snout- vent lengths. From these observations, I consider that size is a perfectly valid character for differentiation of subspecies in Ameiva. 56 Annals of Carnegie Museum VoL. 41 Systematic Review Ameiva auberi cacuminis, new subspecies holotype: AMNH 83028, an adult male, from Ensenada de Cajon, Pinar del Rio Province, Cuba, taken December 22, 1958, one of a series collected by Ar- mando Garcia, Ronald F.

Garrido. diagnosis: A Cuban subspecies of A. aul)eri characterized by a combination of small size (males to 80 mm., females to 60 mm. snout-vent length), moderate number of fourth-toe subdigital scales, femoral pores, and scales in the fifteenth caudal verticil; dorsum brown with an inconspicuous median yellow line in adults, brown with prominent lemon-yellow line in subadults and juveniles, lateral fields black with irregular red edges; and throat dusky gray. DISTRIBUTION: Kuown only from the extreme tip of Cabo de San Antonio, Pinar del Rio Province, Cuba; all distributions shown in Fig. 1. DESCRIPTION OF HOLOTYPE: All adult male with the following measurements and counts: snout-vent length 72 mm., tail 167 mm.; ventrals in 32 longitudinal and 10 transverse rows; fourth-toe subdigital scales 41 and 42 (total 83); femoral pores 14 and 14 ( total 28 ) ; 27 scales in the fifteenth caudal verticil. Dorsal ground color brown in life, with the median and two dorsolateral lines inconspicuously yellow; lateral fields vaguely outlined above by the dorsolateral yellowish lines, solid black with irregular red edges. Throat dusky gray; venter dull grayish blue. Tail grayish blue above, slightly brighter below, with ventrolateral white stripe moderately con- spicuous along the basal third of tail. Limbs brown above, with some very vague darker marbling. VARIATION: The series of 17 specimens of A. a. cacuminis has the following counts: longitudinal ventrals 30-33 (mode 32); rows of transverse ventrals 10 in all specimens; fourth-toe seales 66-83 (mean 75.1); femoral pores 24-29 (mean 25.6); fifteenth verticil 24-29 (mean 26.4). The largest male has a snout-vent length of 80 mm., the largest female (the only adult female in the series) 60 mm. The longest series of paratypes was collected by myself and party in 1958. In life, these specimens were recorded as being brown dorsally, with the median dorsal line lemon yellow in juveniles and subadults, and less conspicuously yellow in adults. In all there is no indication of a black throat, the throats being dusky gray. The lateral fields are solid black without any interior red dotting; red pigment occurs only along the edges of the lateral fields as a series of ragged and irregular scallops or blotches. The USNM, MCZ, and IB paratypes (of which USNM 51851 is the largest male and USNM 51795 is the largest female) 1970 Ameiva auberi: I. The Cuban Subspecies 57 agree well with the fresh material, except that one specimen (USNM 51851 ) has a few isolated red dots in the lateral fields, and the edges of the fields are somewhat more extensively red than in all other specimens. No lizard has any indication of black on the throat or chest. REMARKS: The series from the type locality was collected in xeric for- est along the coast of the Ensenada de Cajon. Few adults were seen, although juveniles were quite abundant in the woods and along the beach front.

Gehrmann; AMNH 79232, western coast, Cabo Corrientes, July 10, 1957, A Garcia, DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of large size (males to 96 mm., females to 78 mm. snout-vent length), moderate number of fourth-toe subdigital scales, high number of femoral pores and scales in the fifteenth caudal verticil; dorsum olive-tan, unicolor in adults and with the median and dorsolateral lines yellowish in juveniles and subadults, lateral fields variable but most often with the black extremely restricted to a series of discrete blotches in the lateral field area and with consequent extensive reddish areas along the margins of the fields; and throat and chest black. DISTRIBUTION: The Peninsula de Guanahacabibes, from the western shore of Cabo Corrientes west to about 45 km. west of Cayuco, Pinar del Rio Province, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 96 mm., tail 187 mm., tip regenerated; ventrals in 32 longitudinal and 10 transverse rows; fourth-toe subdigital scales 39 and 38 (total 77); femoral pores 15 and 16 (total 31); 29 scales in the fifteenth caudal verticil. Dorsum olivaceous tan, with no indications of median or dorsolateral lines; lateral fields much reduced, consisting of a linear series of small and rather disjunct black blotches bordered above and below with reddish. Lower sides olivaceous, somewhat mottled with greenish and not set off from the lateral fields by pale lateral lines. Throat and chest black, the black extending to about the level of the fourteenth row of ventrals, although more diluted, and restricted to the margins of the ventrals posteriorly; venter bright blue laterally, lighter and grayer centrally. Limbs concolor with dorsum on upper sides, forelimbs dark 58 Annals of Carnegie Museum VoL. 41 blue-gray ventrally, hindlimbs blue ventrally. Tail olivaceous blue above, purer blue below; ventrolateral pale caudal stripe absent. variation: The series of 59 specimens of A. a. denticola has the following counts: longitudinal ventrals 31-34 (mode 32 or 33); rows of transverse ventrals 10, 12 (2 specimens), or 14 [(1 specimen) (mode 10)]; fourth-toe scales 67-86 (mean 76.4); femoral pores 23-31 (mean 27.1); fifteenth verticil 24-33 (mean 28.0). The largest male has a snout-vent length of 96 mm. and the largest female 78 mm. The long series of adult paratypes agrees with the description of the holotype in all details except the condition of the lateral fields. Although the modal condition is as described for the holotype — a series of dis- junct black blotches bordered above and below by dull reddish areas — at times the lateral fields may be more complete and have a discrete reddish border both above and below, enclosing a more or less irregular and sinuous black “line” from the neck to the groin. Occasional speci- mens have the lateral fields solid black, or solid black with a very few isolated reddish dots. The ventrolateral caudal stripe is absent in adults. Subadults and juveniles are lineate dorsally, the lines yellowish and not especially contrasting to the olive ground color. The lineate condition is pronounced only in juveniles, and by the time a snout-vent length of about 70 mm. is reached, most subadults have the dorsum unicolor and patternless like that of the much larger adults. Since A. a. denticola is a black-throated race, special comment is re- quired. All adult and subadult specimens (37 males and 21 females) were graded into three categories: ( 1 ) throat and chest completely black; (2) throat and chest only partially black; and (3) throat and chest without black. All specimens (15) in category 1 are males, ranging in snout-vent lengths from 64 mm. to 96 mm. (thus including the largest male). Category 2 includes 12 males and 9 females. The males range in snout-vent length from 70 mm. to 93 mm. (and are thus bracketed in size by the males of category 1), and the females from 56 mm. to 75 mm. (thus not including the largest female). Category 3 includes 11 males with snout-vent lengths from 66 mm. to 90 mm., and 12 females from 58 mm. to 78 mm. (thus including the largest female). From these data it is obvious that most males (27 of 37) have some black on the throat and chest, but that black pigment is not restricted to large speci- mens. In females, only nine of 21 specimens have black on the throat and chest, and in denticola the black pigment in females is never as extensive as it is in males. These peculiarities are difficult to analyze. All speci- mens are summer-collected, so it is possible that here (and in the other black-throated races) the black-throated coloration is somehow 1970 Ameiva auberi; I, The Cuban Subspecies 59 correlated with season (see comments below) or with sexual aetivity. If the latter is the ease, it seems strange that a small male with a snout-vent length of only 64 mm. would be sexually mature. My sug- gestion is that the blaek ehest and throat may appear in males of the black-throated subspeeies at any size onee the early juvenile condition is past. Thus, some individuals become black-throated at a small size and others achieve this state only with a much larger size. This im- plies that males without a black chest and throat at a larger size (for instanee, 90 mm., the largest non-black-throated male in the present lot of specimens) have still to reaeh this eondition. The situation in females is comparable, although in denticola there is no evidenee that females are ever completely black-throated and blaek-ehested. The fact that the largest female of the series lacks any black pigment suggests that this lizard has still not reached that con- dition but would ultimately have done so. In arguing against the premise that possession of black throats is a seasonal phenomenon, I note here that in other black-throated races where speeimens have been eolleeted in both winter and summer, there is no difference in frequency of black-throated lizards by season. COMPARISONS: The raees cacuminis and denticola can be distin- guished by three features: (1) the former is brown dorsally, the lat- ter olivaeeous tan; (2) the former is gray-throated, the latter black- throated and black-ehested; (3) the former has a solid black lateral field, the latter has the lateral field usually very much reduced and fragmented. Of all the raees of A. auheri, only denticola has sueh a wide varia- tion of number of transverse rows of ventrals, although the modal eondition of 10 rows is strong. Only two lizards (AMNH 79215 and 79221) have eounts of 12 rows, and one (AMNH 79219) has a eount of 14. These variants are purely easual and have no taxonomic significance. remarks: The area whence most of the specimens of A. a. denti- cola were secured is a xeric region of sandy soils and diente de perro I ( dog’s tooth — hence the name denticola ) eroded limestone on the ' Peninsula de Guanahaeabibes. The large number of specimens of I denticola attests to the abundance of ground lizards in this particu- I larly favorable habitat. The series from 40 km. west of Cayuco was j taken in monte (lowland broadleaf forest) in a more mesie situation woods oceupied by cacuminis at the tip of the peninsula. 60 Annals of Carnegie Museum VoL. 41 The differentiation of A. auberi into two subspecies on the Penin- sula de Guanahacabibes is difficult to explain, but the same pheno- menon will be observed later on the much shorter and more attenuate Peninsula de Hicacos in Matanzas Province. Actually, all records for denticola are on the southern coast about the Ensenada de Corrientes, whereas the records for cacuminis are on the northern coast. In 1960, David Leber and I collected between Cayuco and the Valle de San Juan in apparently suitable habitats. The road in this region is about equidistant from the north and south shores of the peninsula. No Ameiva were seen. It is possible that cacuminis and denticola repre- sent north- and south-^hore subspecies on the peninsula, rather than basal and distal subspecies. The lack of specimens from the more cen- tral portions ( latitudinally ) of the Peninsula or the more distal re- gion (longitudinally) precludes any definite resolution of the problem. Certainly the Peninsula de Guanahacabibes is a significant region zoogeographically. From it have been described one endemic species ( Anolis quadriocellifer Barbour and Ramsden ) and several endemic sub- species of more widely ranging reptiles (Leiocephalus carinatus zaijasi Schwartz, Leiocephalus stietigaster stictigaster Schwartz, Leiocephalus macropus koopmani Zug, Dromicus andreae peninsulae Schwartz and Thomas). The peninsula is generally, despite its relatively poor rainfall of 115 to 125 cm. per year (Marrero, 1951:442), well wooded, and at the time of my last visit in 1960, was more or less uncultivated, especially to the west. There are several sinkhole lakes, such as that at Vallecito de San Juan, which are surrounded by luxuriant broadleaf trees with epiphytes and lianas. Such interior wooded regions contrast strongly with the more bleak and arid southern coastal portion about the Ensen- ada de Corrientes. To the east, the peninsula abuts upon the flat, lake- studded plains of southwestern Pinar del Rio (see Marie-Victorin and Leon, 1944:132-33 and 302-04 for typical photographs of this interest- ing region). These plains are inhabited by the following subspecies of A. auberi.

DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of very large size (males to 136 mm., females to 115 mm. snout-vent length), low number of fourth-toe subdigital scales, moderate number of femoral pores, high number of scales in the fifteenth caudal verticil; dorsum brown, unicolor in adults and subadults but juveniles showing median and dorsolateral yellow lines, lateral fields with more black than red, the red pigment usually forming a series of dorsal and ventral scallops along the upper and lower borders of the field with each lower scallop about two to three times the area of each dorsal scallop; and throat and chest yellow. DISTRIBUTION: Pinar del Rio Province, from the vicinity of Cayuco in the south- west, north at lower elevations (about 1000 feet) in at least the southern and central portions of the Sierra de los Organos and Sierra del Rosario, as far east as San Diego de los Banos and Dayaniguas on the south coast, and north on the coast to Bahia Honda and Cabanas. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 119 mm., tail 267 mm.; ventrals in 34 longitudinal and 10 transverse rows; fourth-toes missing; femoral pores 14 and 14 (total 28); 27 scales in the fifteenth caudal verticil. Dorsal ground color brown in life, with no indications of median or dorsolateral lines; lateral fields prominent and bold, consisting of a black sinuous band with both dorsal and ventral brick-red scallops, the ventral scallops about three times the size of the dorsal scallops; ventral scal- lops separated by ventrad extensions of black pigment and thus more or less dis- crete. Lower sides blue, mottled with irregular and somewhat tigroid blackish blotches; blue of sides continuous onto venter, involving chest (where blue is ad- mixed with yellow) and all enlarged ventral scales except the paramedian rows. Anterior faces of hindlimbs and sides of tail bluish gray, with a white ventrolateral stripe on the proximal third of the tail; cheeks, throat, sublabials ( and chest, where admixed with bluish gray) yellow. Limbs grayish brown much marbled 62 Annals of Carnegie Museum VoL. 41 with black above, and pale blue-gray to yellowish below, variation: The series of 62 specimens of A. a. procer has the following counts: longitudinal ventrals 31-35 (mode 33); rows of transverse ventrals 8 (3 speci- mens), 9 (1 specimen) or 10 (mode 10); fourth-toe scales 63-84 (mean 71.9); femoral pores 21-31 (mean 26.0); fifteenth verticil 24-31 (mean 27.3). The largest male has a snout-vent length of 136 mm., the largest female 115 mm. The large lot of A. a. procer agrees well with the description of color- ation and pattern of the holotype. The major variation is in the lateral fields. The holotype represents the modal condition. Occasional indivi- duals have the red pigment so much expanded that the black areas are restricted to irregular blotches in an otherwise brick-red field. In all fresh specimens, the throats (and chests, unless they are additionally overlaid with grayish) were yellow, and no specimen shows any ten- dency toward the black throat of denticola to the southwest. Specimens from the vicinity of Cayuco, however, show a tendency toward having the throats orange rather than yellow. The unlined dorsum is a constant feature of adults. In juveniles and males to snout-vent lengths of about 80 mm. and females to about 87 mm., the usual juvenile pattern of a median and two dorsolateral yel- lowish lines is displayed. COMPARISONS: A. a. procer differs from both cacuminis and denticola in having a yellow throat ( in contrast to dusky gray and black throats ) , and in being much larger than either of the two more western sub- species. In fact, procer is the largest of any Cuban subspecies of A. auberi. The brown dorsum of procer contrasts with the olive-tan dor- sum of denticola but is like the brown back of cacuminis. Although as usual the modal number of transverse rows of ventrals is 10 in procer, three specimens have counts of 8 rows, and one has an irregular count of 9. Remarks: A. a. procer occupies a wide variety of situations, from the flat, grassy, lake-studded plains between Isabel Rubio and Cayuco in the southwest to the southern slopes and interior of the Sierra de los Organos and Sierra del Rosario to elevations of 1000 feet. In these mountain ranges, as noted in the introduction, Ameiva occupies the valley floors and the drier uplands, and not the heavily wooded and mesic mogote sides and tops or associated rich forests. A. a. procer is common in the vicinity of San Vicente, occurring there along the road- sides and in cane fields and truck gardens. Most of the series of para- types were collected by native boys while cutting sugar cane. In the mountains to the north and northeast of San Vicente, the lizards are less abundant in the rather more arid woods that occupy gravelly soils. 1970 Ameiva auberi: I. The Cuban Subspecies 63 Specimens from 7.6 miles east of Isabel Rubio were taken in riparian growth along a small stream in a pasture, and those from 13 miles soutliwest of Isabel Rubio were collected along the margin of a lake in a dry pasture. The specimens from 1 mile northwest of Cayuco were taken from a well-shaded encinal with palmetto undergrowth. Barbour (1914:309) reported the occurrence of A. auberi at Herra- dura and Pinar del Rio city, but no specimens are available from either loeality. The latter record almost certainly pertains to A. a. procer, which may also occur at Herradura, although that area might be oc- cupied by the following subspecies. There is no evidence of intergradation between procer and denticola, although it is to be expected between the westermost record of procer (8.2 mi. W. Cayuco) and the easternmost record of denticola (western coast, Cabo Corrientes), a distance of about 16 kilometers. It is possible that denticola occupies only the arid coastal section of the Peninsula de Guanahacabibes, and procer the more mesic plains about Cayuco, and that the zone of intergradation between the two forms is rather narrow and restricted to the region where these two habitats come in contact with one another. The relationships of A. a. procer to the race to the northeast will be discussed under that form. Ameiva auberi paulsoni, new subspecies holotype: AMNH 83012, an adult male, from 1 km. N.

C. Leber, j DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of i moderate size (males to 92 mm,, females to 75 mm. snout-vent length), low num- I ber of fourth-toe subdigital scales, femoral pores, and scales in the fifteenth caudal verticil; dorsum reddish brown with bright lemon-yellow median and dorsolateral lines in adults, lateral fields black with a series of small red dots or scallops along 1 only the ventral border of the fields; and throat cream colored. distribution: Known only from the vicinity of Las Canas and La Coloma on , the south-central coast of Pinar del Rio Province, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and j counts: snout-vent length 92 mm., tail (incomplete and regenerated) 123 mm.; ! ventrals in 34 longitudinal and 10 transverse rows; fourth-toes missing; femoral I pores 12 and 13 (total 25); scales in the fifteenth caudal verticil damaged. Dorsal j ground color reddish brown in life, with bright lemon-yellow median and dorsolat- I eral lines, the latter extending onto the basal portion of tail as a dorsolateral pair 64 Annals of Carnegie Museum VoL. 41 of yellowish streaks; lateral fields black with a series of discrete reddish dots along their lower borders only, and extending behind the hindlimbs onto the sides of the tail as a broad black lateral stripe; lower sides tigroid blue-gray and darker gray; venter very pale blue centrally and darker grayish blue laterally. Throat cream; chest cream with some very pale bluish suffusions and a few isolated black- ish flecks on the third and fourth transverse rows of ventral scales. Upper surface of forelimbs and hindlimbs reddish-brown, with black tigroid markings. Tail deep blue above, with dorsolateral yellowish lines, bordered below by the black lateral streak, which in turn is bordered below by a bold white ventrolateral stripe; under side of tail pale blue. VARIATION: The series of 28 A. a. paulsoni has the following counts: longitudinal ventrals 30-34 (mode 32); rows of transverse ventrals 10 in all specimens; fourth- toe scales 61-77 (mean 68.6); femoral pores 20-28 (mean 24.2); fifteenth verticil 24-27 (mean 25.6). The largest male has a snout-vent length of 92 mm., the largest female 75 mm. In all details of pattern and coloration, the series of A. a. poiilsoni is very consistent. The striking configuration of the lateral fields is espe- cially noteworthy and is a regular feature of the series. No lizard shows any tendencies toward having the throat any color (including black) other than cream. The persistence of the lineate dorsal pattern into full adulthood in both sexes is an outstanding character. COMPARISONS: A. a. paulsoni can be differentiated by its cream- colored throat from the races cacuminis ( dusky gray ) , denticola ( black ) , and procer (yellow). A. a. paulsoni is larger than cacuminis, about the same size as denticola, and distinctly smaller than its relative procer to the north, west, and east. The lateral field pattern of a row of reddish : dots along the ventral border of the fields is characteristic of paulsoni and occurs in no other subspecies. In addition, the reddish-brown dor- sal coloration and persistent dorsal lines distinguish paulsoni from the other western subspecies. A. a. paidsoni has the lowest mean of fourth-toe scales of all Cuban subspecies of A. atd)eri, and the means of femoral pores and fifteenth verticil scales are also low. REMARKS: The region whence A. a. paulsoni is known is occupied by two endemic subspecies of other wide-ranging Cuban species of rep- | tiles — Anolis sagrei bremeri Barbour and Tropidophis melanurus dysodes Schwartz and Thomas. La Coloma lies in a region of low and rather moist palm savannas on the Llanura Costera del Sur de Pinar del Rio (Marrero, op cit. :430 et seq.). The Las Canas lizards were f taken on wet sand about a garbage dump adjacent to a borrow-pit pond and rather near the coast. The Llanura Costera del Sur is a region of low average rainfall (115 to 140 cm. annually), but the general ] aspect of the countryside is not arid. Stands of palms ( including Sahal parviflora, Cameraria retusa, and Colpothrinax wrighti ) and occasion- 1970 Ameiva auberi; I. The Cuban Subspecies 65 al pines occur in wide areas of open grassy flats, which give an almost cultivated and pastoral aspect to the region. The complete distribution of A. a. paidsoni doubtless is more exten- sive than indicated by the three adjacent localities whence it has been taken. Although I have collected on the southern Pinar del Rio coast to the east of the known range of paidsoni at Herradura, and to the west at Punta de Cartas and San Juan y Martinez, no Ameiva were observed at either locality. The localities for paidsoni are about 42 kilo- meters airline from the nearest locality of procer to the west (7.6 mi. E. Isabel Rubio), about 46 kilometers airline from the nearest procer locality to the northeast (San Diego de los Banos), and about 38 kilo- meters from the nearest procer to the east ( Dayaniguas ) .

TYPE LOCALITY: Cuba; restricted to the vicinity of La Habana, Habana Prov- ince, Cuba. diagnosis: A Cuban subspecies of A. auberi characterized by a combination of moderate size (males to 92 mm., females to 88 mm. snout-vent length), moderate number of fourth-toe subdigital scales, and high number of femoral pores and scales in the fifteenth caudal verticil; dorsum rusty brown to brown in adults, juveniles with a vivid lemon-yellow median dorsal stripe, lateral fields with much red pigment, the black areas usually forming a reticulum; and throat orange. distribution: The north coast of Cuba, from Marianao and La Habana on the west, east to the vicinity of Canasi, Matanzas Province, on the east, but see dis- cussion below. variation: The series of 33 A. a. auberi has the following counts: longitudinal ventrals 32-35 (mode 32); rows of ventrals 10 in all specimens; fourth-toe scales 68-89 (mean 76.3); femoral pores 23-31 (mean 26.6); fifteenth verticil 26-31 (mean 28.2). The largest male has a snout-vent length of 92 mm., the largest female 88 mm. In living material, the dorsal ground color of A. a. auberi varies from rusty brown to brown; the back is unicolor and without longitudinal lines. In juveniles there is a vivid yellow median dorsal line and some- what less obvious dorsolateral yellow lines, all of which persist in var- ious degrees of intensity into subadults. The lateral fields are reddish, and usually this pigment is so extensive that the black in the lateral" field is reduced to a black reticulum or to a linear series of practically discrete black blotches. The lower sides are blue (PI. 26 L 1; all color designations from Maerz and Paul, 1950) and this color extends onto 66 Annals of Carnegie Museum VoL. 41 the ventral scales, the more central rows of which are much paler. The throat and chin are orange (PI. 10 J 9, PL 9 B 12), somewhat lighter (almost yellow) on the cheeks, and the axillae and chest are likewise orange. The orange chest coloration may extend as a pinkish wash over the blue of the venter as far as the vent, onto the under side of the hindlimbs and tail, and onto the inner surface of the forelimbs. Juve- niles have the bellies pink, the throats yellow to pinkish, and tails vivid blue, whereas the tail in adults is brown above and grayish blue to purplish below. The ventrolateral pale tail stripe is whitish to grayish, and not especially prominent in adults. COMPARISONS: A. a. auheri differs from all other described subspecies in having the throat orange, and often having an orange wash over the venter and underside of the hindlimbs. No specimens show any ten- dency toward having a black throat or chest, although there are often a few scattered gray scales in the otherwise brightly colored throat. In dorsal coloration, lack of persistent dorsal stripes, and restriction of the black in the lateral fields, auheri most closely resembles procer to the west. The very large size and yellow throat of procer contrast with the smaller size and orange throat of auheri. REMARKS: A. a. auheri occurs along the north coast of Habana and Matanzas provinces. I have encountered no specimens in any situations except coastal habitats — seagrape stands and on beaches at the base of the sea cliffs that abound in this stretch of coastline. There are spec- imens in collections from La Habana and its suburbs ( Marianao, Regia ) that indicate that ground lizards are in part urban in this area, and may occur some short distance inland from the ocean proper. Barbour’s (1914:309) reports of A. auheri from two localities in Habana Province ~™ Cojimar and Madruga — are unsubstantiated by specimens. The first locality is within the known range of A. a auheri (between La Habana and Boca de Jaruco) and the second lies on the Habana-Matanzas bor- der, inland about 60 kilometers from the coast. I have seen no lizards from this general region and the assignment of Ameiva from Madruga to any specific subspecies must await material. 1 suspect that they will be found to be black-throated and black-chested like the subspecies next to the east of A, a. auheri. SPECIMENS examined: Cuba, Habana Province, Marianao, 1 (USNM 28007); La Habana, 4 (USNM 58486-58488, AMNH 65599); Regia, 1 (USNM 128105); 2 mi. E. Playa de Guanabo, 2 (AMNH 78021-78022); Boca de Jaruco, 2 (AMNH 78027-78028); 2 mi. E.

Canasi, 5 (AMNH 1970 Ameiva auberi: I. The Cuban Subspecies 67 82944 — 5 specimens); 6.6 mi. N.E. Canasi, 2 (AMNH 82945 — 2 specimens). There are eight specimens from northeastern Pinar del Rio Province that are anomalous: USNM 27617-27618 and USNM 27668-27671 from Mariel, and AMNH 82964-82965 from 5 km. north of Mariel. The first two lots are old specimens and are much discolored. The last two specimens were collected by myself. As far as can be determined from the old specimens, the males from Mariel are characterized by having at least a black chest (males with snout- vent lengths from about 70 mm. to 87 mm.). One of the recently collected males (snout-vent length 73 mm. ) also has indications of a black chest. The single female appears not to have had any black chest or throat pigment. The throats of the two recently collected males ( snout- vent lengths 80 and 73 mm. ) were recorded as dirty cream and grayish. The dorsa of adults were apparently some shade of brown, and the subadults show some indica- tion of lines. Since procer with a yellow throat occurs to the west at Cabanas, and auberi with an orange throat to the east at Havana, it seems that there is interposed between these two races a black-chested subspecies (neither of the two adjacent populations ever has any indication of a black chest or throat). I withhold any subspecific de- signation on the specimens from Mariel until additional fresh material from the northeastern portion of Pinar del Rio Province and the extreme northwestern portion of Habana Province becomes available.

San Miguel de los Banos, Matanzas Province, Cuba. DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of small size (both males and females to snout-vent length of 81 mm., but see dis- cussion below), moderate number of fourth-toe subdigital scales, high number of femoral pores, and moderate number of scales in the fifteenth caudal verticil; dorsum brown, adults unicolor or with faint yellow median and dorsolateral lines, juveniles prominently lined with yellow, lateral fields with black restricted to a series of vertical bars (often absent anteriorly), and red areas almost completely replaced by tan-to-brown, practically concolor with dorsum; throat with a black median spot, and chest black. 68 Annals of Carnegie Museum VoL. 41 DISTRIBUTION: From the vicinity of the city of Matanzas east to Cardenas (but excluding the distal half of the Peninsula de Hicacos), and presumably inland as far as the vicinity of San Miguel de los Banos ( see discussion ) in Matanzas Prov- ince, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 78 mm., tail 163 mm.; ventrals in 33 longitudinal and ] 10 transverse rows; fourth-toe subdigital scales 38 and 38 (total 76); femoral j pores 14 and 14 (total 28); 25 scales in fifteenth caudal verticil. Dorsum brown I with median and dorsolateral yellow lines very faint but present; lateral fields ob- j scure and composed of about 8 to 10 very reduced black vertical bars or dots on j the posterior half of the trunk, the balance of the fields completely obscured by j tan pigment. Chest black, pigment extending onto anterior and ventral faces of ! forelimbs; throat with a rather extensive, but incomplete anteriorly and laterally, i black spot. Belly very pale blue; lower sides dark gray-blue with few very vague j tigroid markings; upper side of limbs brown with dark-gray tigroid markings. ! Tail brown above, blue-gray below with the ventrolateral pale stripe much re- j duced and restricted to the anterior third of the tail. VARIATION: The series of 24 A. a. pullata has the following counts: longitudinal ventrals 31-34 (mode 32); rows of transverse ventrals 10 or 12 (3 specimens); fourth-toe scales 64-86 (mean 75.0); femoral pores 23-31 (mean 26.3); fifteenth verticil 24-29 (mean 26.8). The largest male has a snout-vent length of 81 mm., the largest female 81 mm. (see below). Considering only the speeiinens from between Matanzas and Car- denas, and excluding those from San Miguel de los Banos, the para- types agree very well with the description of the holotype in coloration j and pattern. In life, the median and dorsolateral stripes occur in most jl adults but are never so prominent as they are in subadults and juve- niles. The lateral fields are variable but regularly have more tan (rath- i er than red) and the black area is much restricted or even limited to disjunct series of bars or irregular blotches. The black chest and throat i — the latter never completely black but having rather a black spot i posteriorly — occur only in males. As in the other black-throated sub- species, the size at which the black throat occurs in males is variable ! in the sample. The smallest (of 13) male with the complete black chest j: and throat spot has a snout-vent length of 68 mm., the largest 78 mm. All other males with snout-vent length from 66 mm. to 70 mm., have ' the chest black and an incipiently black spot on the throat, with the exception of one small male, with a snout-vent length of 66 mm., which lacks any black on the throat or chest. In females, the maximal black jl chest and throat-spot condition is equivalent to the intermediate con- dition in males — a black chest and an incipient black throat spot. Females in this category range in snout- vent lengths from 62 mm. to ■ 72 mm. Females with snout-vent lengths of 52 mm. to 63 mm. have the chest and throat without black pigment. (i 1970 Ameiva auberi: I. The Cuban Subspecies 69 The four specimens from San Miguel de los Banos present a differ- ent picture. The largest male and the largest female pullata (both 81 mm.) are drawn from this small San Miguel sample. Otherwise, the largest pullata (from the coastal sample) male measures 78 mm. and the largest female 72 mm. Thus the two San Miguel females (snout- vent lengths 76 and 81 mm. ) are larger than all coastal females and the two San Miguel males are large (snout-vent lengths 76 mm. and 81 mm.) and at the upper extreme of the coastal males. The larger San Miguel female also has the tlu'oat and chest as black as coastal pullata males — a condition not known for coastal females — and the larger San Miguel male also has the throat more extensively black than any coastal pullata. Everything considered, I doubt that the San Miguel series is correctly regarded as A. a. pullata, and doubtless represents a local interior subspecies. However, absence of an adequate series from interior Matanzas Province precludes further comment. COMPARISONS: A. a. pullata requires comparison only with the other black-throated population thus far described — A. a. cleiiticola. In the latter, the throat and chest are wholly black, rather than having only a black spot as in pullata. A. a. clenticola reaches a larger size, and has black lateral fields with red edges, rather than restricted black mark- ings with extensive tan edging in the lateral field region. The two races are separated by the subspecies procer and auberi. From auberi, the race closest to the west (the closest records of auberi and pullata are 6.6 mi. N.E. Canasi and near Matanzas — about 27 kilometers airline but actually somewhat farther since the Bahia de Matanzas inter- venes), pullata differs especially in having the black chest and throat spot, whereas auberi has the throat orange. A. a. pullata also is bordered on the north by the next race from the Peninsula de Hicacos and prob- ably also meets another subspecies from the northeastern corner of Las Villas Province. Comparisons with these races will be made later. REMARKS: The AMNH type material of A. a. pullata (with the ex- ception of the specimens from Cardenas, which were not taken recently) was collected in grassy areas on the landward side of the extensive beach between Matanzas and the base of the Peninsula de Hicacos, and on the beach itself, in scanty gi'owth of herbs and grasses. The specimens from San Miguel de los Banos were taken in a cut-over Canaveral and in grass along its edges. At the latter locality, the lizards were not abundant, whereas along the beaches they were exceptionally common. 70 Annals of Carnegie Museum VoL. 41 Ameiva auberi abducta, new subspecies holotype: AMNH 96331, an adult male, from Punta Hicacos, Matanzas Prov- ince, Cuba, taken June 30, 1960, by David C. Leber, Original number 886L PARATYPES: AMNH 96332-96360, 8.9 mi. N.E. Varadero, Matanzas Province, Cuba, June 30, 1960, R. F, Klinikowski, D. C. Leber, J. D. Smallwood; IB 133-134, Dupont, Matanzas Province, Cuba, July 6, 1966, O. H. Garrido. DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of moderate size (males to 87 mm., females to 68 mm. snout-vent length), moderate number of fourth-toe subdigital scales and femoral pores, high number of scales in the fifteenth caudal verticil; dorsum brownish with persistent pale yellowish tan median and dorsolateral lines in adults, lateral fields usually inconspicuous with black restricted to discrete vertical bars or blotches or absent entirely, lateral field red replaced by brownish; and throats yellowish orange. DISTRIBUTION: Known only from the distal half of the Peninsula de Hicacos, Matanzas Province, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 85 mm,, tail 181 mm., tip missing; ventrals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales -/36; femoral pores 12 and 13 (total 25); 28 scales in fifteenth caudal verticil. Dorsum dull brownish with median and dorsolateral lines present and yellowish tan; lateral fields obscure and composed of a black reticulum with extensive invasion of brownish, concolor with dorsum. Throat yellowish orange; venter and chest dull bluish. Lower sides dark bluish gray with some vague darker gray tigroid mark- ings. Tail brownish above, dull blue-gray below, ventrolateral caudal stripe ob- scure. Limbs brownish above with vague darker markings. VARIATION: The series of 30 A, a. ahclucta has the following counts: longitudinal ventrals 31-34 (mode 32); rows of transverse ventrals 8 (3 specimens) or 10; fourth-toe scales 64-84 (mean 75.2); femoral pores 21-30 (mean 25.4); fifteenth verticil 24-29 (mean 27.6). The largest male has a snout-vent length of 87 mm., and the largest female has a snout-vent length of 68 mm. The series of paratypes agrees well with the description of color and pattern of the holotype. The persistence of the yellowish tan median and dorsolateral lines is consistent in all adults, although in all cases these lines are not particularly contrasting with the rather drab brown- ish dorsal ground color. Major variation occurs in the condition of the lateral fields. These may be somewhat more distinct than in the holo- type, depending upon the precise shade of the invading tan or brown- ish pigment and the extent to which it has restricted the back pigment. Some ahducta lack any sort of black markings in the lateral fields what- soever, whereas in others the black areas are a less intense gray. Juve- niles are not appreciably more brightly colored than adults, although the dorsal lines may be somewhat more apparent. COMPARISONS: A. a. ahducta requires comparison with three other subspecies: paulsoni (which is also dorsally lined in adulthood), auberi (which has an orange throat), and pullata (which is geographically 1970 Ameiva auberi: I. The Cuban Subspecies 71 adjacent). All other described races are distinguishable by throat color or dorsal pattern. From paulsoni, abducta differs in throat color ( yellow- ish-orange versus cream), in having the dorsal ground color paler (brownish versus reddish brown) with consequent loss of intensity of the dorsal lines (which are bright lemon-yellow in paulsoni and yel- lowish tan in abducta). From auberi, which has a brightly colored throat, abducta differs in having a lineate and paler (brownish versus rusty brown-to-brown ) dorsum, and a less brightly colored throat. The ranges of auberi and abducta are separated by that of pullata. From geographically adjacent pullata, abducta differs in having a yellowish orange throat in contrast to a black chest and black-spotted throat. Although both abducta and pullata are striped dorsally, the striping in pullata is much fainter and less consistent an adult feature than in abducta. REMARKS: The Peninsula de Hicacos extends in a northeastern direc- tion from the north coast of Matanzas Province, and is about 20 kilo- meters long. The outer extreme of the peninsula is rather arid, is cov- ered with extensive scrub and dry woods, and has extensive sandy beaches. Ground lizards were abundant in this latter habitat, which they shared with Leiocephalus raviceps klinikowskii Schwartz, and in the scrub itself. The closest records of abducta and pullata (Dupont and 13 km. N.E. Matanzas ) are separated by only 28 kilometers airline, but the latter locality (for pullata) is on the Cuban mainland, and much of the basal portion of the Peninsula de Hicacos is presently con- verted to resorts and hotels and thus not available for extensive collect- ing. Presumably abducta and pullata intergrade between these two re- ported localities. Buide (1966:8), in discussing the peculiarity of dis- tribution of L. f. klinikowskii, suggested that this subspecies had evolv- ed on the peninsula when the latter was insular. The differentiation of A. a. pullata and A. a. abducta may be a comparable situation. Ameiva auberi gemmea, new subspecies holotype: AMNH 82972, an adult male, from mouth of Rio de Sierra Morena, near Playa Ganuza, Las Villas Province, Cuba, taken June 20, 1958, one of a series collected by Albert Schwartz and George R. Zug. Original number 5297. PARATYPESi AMNH 82970-82971, 82973-82981, same data as holotype; AMNH 82983-82985, 0.5 km. S. Playa de Sierra Moreno, Las Villas Province, Cuba, June 22, 1958, G. R. Zug. diagnosis: A Cuban subspecies of A. auberi characterized by a combination of large size (males to 105 mm., females to 97 mm. snout-vent length), moderate number of fourth-toe subdigital scales, femoral pores, and scales in the fifteenth caudal verticil; dorsum reddish brown with median and dorsolateral lines yellow- 72 Annals of Carnegie Museum VoL. 41 ish to brown in adults, lateral fields prominent and extensively blaek with two ineluded rows of diserete brown spots and with seattered bright yellow scales; and throats yellow to orange. DISTRIBUTION: Knowii only from the northwestern corner of Las Villas Province, Cuba, near the Las Villas-Matanzas boundary. DESCRIPTION OF HOLOTYPE: All adult male with the following measurements and counts: snout-vent length 97 mm., tail 182 mm.; ventrals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales 32 and 32 (total 64); femoral pores 13 and 14 (total 27); 24 scales in fifteenth caudal verticil. Dorsum reddish brown with median and dorsolateral lines yellowish and fairly prominent; lateral fields black with two longitudinal series of irregularly placed but discrete and more or less round brown dots, the more ventral of the two series additionally dotted with scattered bright yellow scales; lateral fields bounded below by a bold greenish-grayish longitudinal stripe from above the forelimb to the groin. Lower sides gray with a distinct darker-gray reticulum; belly clear grayish centrally, darker grayish blue laterally on two outermost dows of ventrals. Tail brownish above, pale-gray below, with a bold whitish ventrolateral stripe for about half the length of the tail. Limbs brown above with vague darker reticulations. Throat yellowish, with orange (PI. 10 E 11) suffusions. VARIATION: The series of 15 A. a. gemmea has the following counts: longitudinal ventrals 31-34 (mode 32); rows of transverse ventrals 10 in all specimens; fourth- toe scales 64-80 (mean 73.8); femoral pores 23-30 (mean 25.9); fifteenth verticil 24-30 (mean 25.9). The largest male has a snout-vent length of 105 mm., the largest female 97 mm. The reddish brown dorsum with yellowish-to-brown dorsal lines is a common feature of the entire series. The lines in juveniles are yellow to greenish yellow and are even more bold than in the adults. The exten- sively black lateral fields with their two (or at times, three) rows of discrete, more or less circular, brown spots and additional bright yel- low scales are also of regular occurence, at least in adults, and the lateral fields are bordered below by a well-defined greenish or gray lateral stripe, which continues onto the tail as a bold whitish ventrolateral stripe. The throat color varies from flesh (in juveniles) to yellow or orange (PL 10 K 2 to Pi. 10 E 11) in adults of both sexes, and the cheeks are usually concolor with the throat. The belly varies from very pale blue (usually) to gray, or even faintly purplish in juveniles. COMPARISONS: A. a. gemmea is unlike any other subspecies of A. auheri in having scattered yellow scales in the lateral fields which themselves are distinctive in being extensively black with the double series of discrete brown spots. By these characters gemmea may be distinguished from all other subspecies. In throat color gemmea re- sembles auheri and ahdueta most closely, but the striped dorsum, de- tails of lateral field coloration and pattern, and dorsal color will dis- tinguish gemmea from these two races. The conspicuous lateral fields 1970 Ameiva auberi: I. The Cuban Subspecies 73 of gemmea are in strong contrast to those of the geographically close ahducta. REMARKS: A. a. gemmea is known to occupy only a small area in ex- treme northwestern Las Villas Province, but its range is almost surely more extensive. At the type locality, the ground lizards were collected in brush and Aeaeia on muddy ground in and about a fresh-water swamp, altogether a rather unusual situation for Ameiva. The range of gemmea is removed some 58 kilometers airline from the most eastern record for the next adjacent race to the west, A. a. pullata, at Cardenas. Ameiva auberi extraria, new subspecies holotype: AMNH 82982, an adult male, from Cayo Bahia de Cadiz, Las Villas Province, Cuba, taken June 21, 1958, one of a series collected by Albert Schwartz and George R. Zug. Original number 4380. PARATYPES: AMNH 96250-96280, same data as holotype. ASSOCIATED SPECIMENS (all froiii Las Villas Province, Cuba): IB 41, Cayo Monos de Jutia; IB 64-71, Cayo Lanzanillo; IB 36-40, Cayo Carenero; IB 61-63, Cayo las Tocineras; IB 42-50, Cayo Tio Pepe. DIAGNOSIS: A Cuban subspecies of A. a. auberi characterized by a combination of small size (males to 79 mm., females to 68 mm. snout-vent length), moderate number of fourth-toe subdigital scales, low number of femoral pores, and mod- erate number of scales in the fifteenth caudal verticil; dorsum yellowish brown to reddish with only a pale-yellow median line which does not extend to the groin but is diffuse or absent entirely posteriorly; lateral fields at best only faintly indi- cated by a darker brownish streak, and usually absent completely; and throat gray to diffuse dull orange. DISTRIBUTION: The Archipielago de Sabana off the northern coast of Las Villas Province, Cuba; known from Cayo Bahia de Cadiz, Cayo Monos de Jutia, Cayo Lanzanillo, Cayo Carenero, Cayo las Tocineras, and Cayo Tio Pepe; specimens from Cayo Carenero tend slightly to be intergradient with the subspecies on Cayuelo de la Vela. DESCRIPTION OF HOLOTYPE: All adult male with the following measurements and counts: snout-vent length 75 mm., tail 179 mm.; ventrals in 34 longitudinal and 10 transverse rows; subdigital scales 37 and 40 (total 77); femoral pores 11 and 11 (total 22); 29 scales in fifteenth caudal verticil. Dorsum yellowish brown, un- lined except for a vague remnant of the median line which is very pale yellow and incomplete posteriorly. Lateral fields absent, their position indicated only by a vague grayish band along each side. Tail brownish above, grayish blue below, and without a ventrolateral pale stripe. Throat grayish orange, belly blue. Cheeks pale yellowish; lower sides dull gray. Upper surfaces of limbs concolor with dor- sum and with very vague grayish reticula. VARIATION: I have grouped together as A. a. extraria those speeimens of ground lizard from the Arehipielago de Sabana whose throats are gray (in which case the sublabials and infralabials are orange) to dull orange. Lizards from Cayuelo de la Vela (adjacent to Cayo Carenero) I regard as a distinct form, restricted to that cay, because of their hav- 74 Annals of Carnegie Museum VoL. 41 ing black throats and chests. Of the cays inhabited by extraria, one (Cayo Bahia de Cadiz) lies near the western end of the chain of islets, near the Matanzas-Las Villas line, whereas the balance of the cays lie about 75 kilometers southeast of Bahia de Cadiz and to the east of the town of La Isabela. The series of 55 A. a. extraria has the following counts : longitudinal ventrals 28-34 ( mode 32 ) ; rows of transverse ventrals 8 or 10 ( mode 10, but see comments below ) ; fourth-toe scales 68-88 (mean 76.3); femoral pores 21-27 (mean 23.8); fifteenth ver- ticil 23 - 30 ( mean 26.5 ) . The largest male has a snout-vent length of 79 mm. and is from Cayo Monos de Jutia. The largest female has a snout-vent length of 68 mm. and is from Cayo Bahia de Cadiz. The dorsal color varies from yellowish brown to reddish. The for- mer is the modal adult coloration, the latter that of young subadults and juveniles. The dorsolateral stripes are absent ( as are also the lateral fields), and the median dorsal stripe is pale yellow and never com- plete, disappearing about two-thirds of the way between the neck and the groin. Even the smallest juvenile ( snout-vent length 45 mm. ) lacks the dorsolateral stripes and the lateral fields. The median dorsal stripe in this juvenile agrees in intensity and extent with that of full adults. In juveniles, the tail is not bright blue but concolor with the dorsum. The throat coloration varies from gray (regularly with orange sub- labials and infralabials) to diffuse grayish orange. The differences in throat pigmentation in the topotypical sample may well be correlated with age or sex, but my field notes are not specific in this regard. Sr. Garrido’s notes on the IB material indicate that a male from Cayo Monos de Jutia and one from Cayo Tio Pepe had solid orange throats, whereas males from Cayo Carenero, Cayo las Tocineras, and Cayo Lanzanillo have gray throats with orange sublabials and infralabials. Considering the geographic relationships of these cays to each other, it seems preferable to regard all populations as A. a. extraria rather than attempt to distinguish two subspecies on the basis of throat color. At least lizards from the various cays present a generally uniform dor- sal aspect, although even this, as might be expected, shows some minor variations in intensity of pigmentation. The absence of lateral fields and subdued-to-absent dorsal lineation are common to all samples. There has been some evolution within the Archipielago de Sabana, as far as A. a, extraria is concerned. This is shown by pertinent scale differences between the several populations regarded as extraria. Most noteworthy is the number of transverse ventral rows in the Cayo Tio Pepe sample. Of the nine lizards from this cay, eight have only 8 trans- 1970 Ameiva auberi: I. The Cuban Subspecies 75 verse rows, the ninth having the more orthodox 10. No other Cuban sample studied has such a high incidence of this low count, and in fact no other extraria has a count of 8. There is also a distinct tendency for topotypical extraria (Cayo Bahia de Cadiz in the west) to have more fourth-toe scales (71 to 88), whereas lizards from the group of eastern cays have slightly lower counts (68 to 77 ) . Despite these peculiarities, 1 feel that all should at least temporarily be considered A. a. extraria. There is such an abundance of cays along this northern Las Villas coast, whose Ameiva are as yet unsampled, and the two areas whence specimens are available are so far removed from one another, that to consider all material as extraria seems the conservative course at this time. COMPARISONS: A. a. extraria is geographically closest, of the named subspecies, to A. a. gemrnea, but the two subspecies are very different in pigmentation and pattern. The bold and decorated lateral fields of gemmea differ strongly from the virtually non-existent lateral fields of extraria. The throat color of extraria is darker (gray to dull orange) than that of gemmea ( yellow to orange ) , and gemmea reaches a much larger size than extraria (105 mm. versus 79 mm. in males). The black throats and chests of denticola and pullata distinguish those races from extraria, and the cream throat of paulsoni and the yellow throat of procer distinguish these subspecies. Those races which have gray-to- orange ( although never as dull an orange as extraria ) throats are cacu- minis, auberi, and abducta. All are somewhat larger than extraria, none lacks lateral fields, and none in adults has only a median line without dorsolateral lines. The dorsal pigmentation of extraria is paler than that of any subspecies thus far described. In number of femoral pores, extraria ranks next to the lowest of all Cuban subspecies. REMARKS: At the type locality, A. a. extraria was quite abundant. The vegetation was arid forest and scrub, with some mangroves along the margins of the cay. In general Cayo Bahia de Cadiz is fairly high and rocky, rather than flat and sandy. Although Cayo Bahia de Cadiz lies only about 20 kilometers off the coast and on the fringing bank, whose depth between the coast and the cay does not exceed 1.25 fathoms, the striking differences between gemmea and extraria suggest that either these two subspecies have been long separated from one another or that extraria has not been derived directly from the mainland gemmea but from a more east- ern population. The occurrence of extraria on cays off the coast at La Isabela also suggests that neither gemmea nor the subspecies on the 76 Annals of Carnegie Museum VoL. 41 adjacent coast and at Sagua la Grande has been the ancestor of extra- ria. Resemblances between extraria and subspecies farther to the east are greater than between extraria and any of the more western races (including gemmea, abducta, and pullata). Elaboration of these re- marks will follow in a later section. Ameiva auberi extorris, new subspecies holotype: IB 52, an adult male, from Cayuelo de la Vela, Las Villas Province, Cuba, taken March 11, 1965, one of a series collected by Orlando H. Garrido. PARATYPES: IB 51, IB 56-57, ASFS V11373-11375, sama data as holotype. diagnosis: A Cuban subspecies of A. auberi characterized by a combination of small size (males to 76 mm. snout-vent length, females unknown), low number of fourth-toe subdigital scales, moderate number of femoral pores, and low number of scales in the fifteenth caudal verticil; dorsum dull brown, completely patternless and without lateral fields; and throat with a black spot and chest black, distribution: Known only from Cayuelo de la Vela, Archipielago de Sabana, off the north coast of Las Villas Province, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout- vent length 73 mm,, tail 172 mm.; ventrals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales -/35; femoral pores 13 and 13 ( total 26 ) ; 26 scales in fifteenth caudal verticil. Dorsum ( as preserved, but not strongly different from color notes) brown, completely without any indication of dorsal lines or lateral fields. Throat gray, with a black posterior spot extending onto the mesoptychium; first three transverse rows of ventrals on chest black. Venter dull blue-gray. Limbs brown, concolor with dorsum. Tail dull gray above, blue-gray ( slightly darker than venter ) below, without lines. VARIATION: The series of seven male A. a. extorris has the following counts: longitudinal ventrals 31-33 (mode 33); rows of transverse ventrals 10 in all speci- mens; fourth-toe scales 68-72 (mean 69.5); femoral pores 24-28 (mean 25.3); fifteenth verticil 24-27 ( mean 25.4 ) . The largest male has a snout-vent length of 76 mm.; females are unknown. Little need be said about pattern and color variation in the short series of extorris. The series consists exclusively of males with snout- vent lengths ranging between 64 mm. and 76 mm., and the smaller in- dividuals are exactly like the holotype as far as dorsal pattern and col- oration are concerned. The entire aspect of the lizards is one of ex- treme drabness, without markings of any kind. Males with snout-vent lengths between 68 mm. and 76 mm. have the thi'oat and chest pattern as described for the holotype. The three re- maining males with snout- vent lengths between 64 mm. and 69 mm. lack the throat spot but have some black scales on the mesoptychium and chest. COMPARISONS: A. a. extorris requires comparison with the black- throated and black-chested subspecies heretofore named {denticola, pullata) and with the geographically adjacent extraria. Compared 1970 Ameiva auberi: L The Cuban Subspecies 77 with the subspecies denticola and pullata, extorris is much more drab and lacks dorsal lines and lateral fields. Additionally, the entire throat is black in denticola, whereas pullata resembles extorris in having only a black throat spot. As might be surmised, extorris most closely re- sembles its neighbor extraria, but extorris carries the reduction of dor- sal and lateral markings even further, is generally darker than extraria, and has the black throat spot and chest which extraria lacks. A. a. extorris has the next-to-the-lowest mean of number of fourth-toe scales of all the Cuban subspecies, whereas extraria ranks ninth in this character. EEMAKKS: Although I debated naming the population on Cayuelo de la Vela as a distinct subspecies, the presence of a black throat and chest seems sufficiently distinctive, despite the apparently restricted distri- bution of the subspecies, to separate these lizards from their relatives on the other cays. Interestingly, a small male (IB 52) extraria from Cayo Carenero, the cay closest to de la Vela and separated from it by a narrow channel only two fathoms deep, has a few black scales on the throat, whereas all other Carenero lizards have throats typical of ex- traria. Apparently at least the Carenero lizards still retain the poten- tiality for black throatedness, and isolation of a population of extraria on de la Vela has resulted in the expression of this character on that single island. Ameiva auberi garridoi, new subspecies holotype: IB 96, an adult male, from Ciiatro Bocas, Sagiia la Grande, Las Villas Province, Cuba, taken May 2, 1966, one of a series collected by P. Saavedra. PARATYPES (all from Las Villas Province, Cuba): IB 95, CM 40638--40639, same data as holotype; IB 107-108, IB 110-112, NMC 10066 (3 specimens), CM 40640, same locality as holotype, March 21, 1966, Jorge de la Cruz; ASFS VI 1376, Finca El Dorado, Sagua la Grande, May, 1966, P. Saavedra; ASFS VI 1377-1 1379, IB 116-119, Finca El Dorado, March 9, 1965, O. H. Garrido; IB 79, IB 103, Cayo Boca de Sagua, Isabela de Sagua, May, 1966, P. Saavedra. DIAGNOSIS: A Cuban subspecies of A. atiheri characterized by a combination of large size (males to 110 mm., females to 70 mm. snout-vent length), high number of fourth-toe subdigital scales, very high number of femoral pores, and high num- ber of scales in the fifteenth caudal verticil; dorsum brown and unlined in adults but with a median and two dorsolateral white lines in subadiilts and juveniles; lateral fields black, bordered above and below by a marginal row of large brown- to-tan scallops, which in adults tend to limit the black lateral field color into al- most a series of vertical lateral bars; and throat lemon-yellow. DISTRIBUTION: Known only from the region between the city of Sagua la Grande and La Isabela, in northern Las Villas Province, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 88 mm., tail 185 mm.; ventrals in 33 longitudinal and 10 transverse rows, siibdigital scales 39 and 40 (total 79), femoral pores 12 and 78 Annals of Carnegie Museum VoL. 41 i' I 13 (total 25); 27 scales in fifteenth caudal verticiL Dorsum (as preserved) me- i dium brown and unlined; top of head concolor with dorsum. Lateral fields black I with two rows of brown scallops, one dorsal and the other ventral, limiting the black lateral field pigment into an irregularly shaped but well-defined lateral figure; i lower sides more or less tigroid blue and blue-grey; tail blue-gray above, grayer | below, with the white ventrolateral longitudinal line fairly prominent on the basal half of the tail. Throat and mesopytchium clear, bright lemon-yellow. Chest yel- low, admixed with blue-gray; venter yellowish medially on about first eighteen i transverse rows of ventrals, marbled blue and yellow to cream elsewhere. Limbs ’ blue-gray, vaguely marbled with darker gray, especially on hindlimbs; transverse white thigh line prominent. VARIATION: The series of 23 A. a. garridoi has the following counts: longitudinal ventrals 31-34 (mode 33); rows of transverse ventrals 10 in all specimens; fourth toe scales 68-87 (mean 78.3); femoral pores 25-32 (mean 27,6); fifteenth verticil ; 26-30 (mean. 27.9). The largest male has a snout-vent length of 110 mm., the j largest female 70 mm. i Adults resemble the description of the holotype closely. The median | and dorsolateral lines are seldom in evidence, and when visible, they ; are barely discernible in the preserved material. The lateral fields regularly have a dorsal and ventral row of brown scallops, which may ultimately so restrict and limit the black lateral field pigment that the I latter becomes a series of vertical bars (ASFS V11376, IB 103) especially anteriorly. The throat is bright lemon-yellow in both sexes, although ; apparently the throat color of females is somewhat paler than that of | males. One male ( IB 95, snout-vent length 105 mm., and thus not quite the largest male) has a few black scales on the mesoptychium, and the ' entire venter has some black pigment dispersed on all the ventrals, | although the ventral color is still more blue than black. The largest male (IB 103) shows no evidence of this darkening, nor do any other speci- mens, regardless of sex or size. The white ventrolateral tail line is at least indicated basally in even the largest specimens. ' Females and subadult males and juveniles resemble the adult males in dorsal color and in the configuration of the lateral fields, but there are a median and two dorsolateral white lines. The lateral fields are f also delimited below by a pale line. ) COMPARISONS: A. a. garridoi most closely resembles A. a. procer to the west in Pinar del Rio Province. Both subspecies have yellow throats and both are quite large, although procer exceeds garridoi in size ( 136 mm. versus 110 mm.). Both races have the lateral fields with dorsally and ventrally scalloped edges. Restriction of black lateral field pigment is much more pronounced in procer than in garridoi, however, and the , scallops in procer are brick-red rather than brown as in garridoi. A. a. ' procer has a significantly lower mean (71.9) of fourth-toe scales than 1970 Ameiva auberi: I. The Cuban Subspecies 79 does garridoi (mean 78.3), which ranks third among the Cuban races. In femoral pores, garridoi (mean 27.6) ranks first among the Cuban sub- species, whereas procer has a lower mean (26.0) and ranks tenth. The mean of fifteenth caudal verticil scales are high in both subspecies ( 27.3 and 27.9). A. a. garridoi differs from the other subspecies in having a lemon- yellow throat {cacuminis, denticola, paulsoni, auberi^ pullata, ahducta, gemmea, extraria, extorris), in having a unicolor and unlined dorsum (cacuminis, paulsoni, pullata, ahducta, gemmea), and in having lateral fields well expressed ( ahducta, extraria, extorris ) . The differences between garridoi and closely adjacent (but insular rather than main- land) extraria and extorris are striking in size, coloration, and pattern. The nearest mainland subspecies to the west is gemmea, from which garridoi differs in many details, not the least of which is the absence of the yellow decorative spots in the lateral fields. REMARKS: I have not seen living nor freshly collected examples of A. a. garridoi. All specimens of this subspecies have been collected by Orlando H. Garrido (for whom the subspecies is named), Jorge de la Cruz, and P. Saavedra. Sr. Garrido (in litt., March 17, 1966), after having collected the first specimens of garridoi, noted the distinct char- acters of this population as he collected material at El Dorado and along the banks of the Rio Sagua la Grande. I am very grateful to Sr. Garrido for allowing me to describe this distinctive subspecies and it gives me great pleasure to name it in his honor. Doubtless A. a. garridoi will be found to have a wider distribution than the few locality records presently indicate.

DIAGNOSIS: A Cuban subspecies of A. auheri characterized by a combination of large size (males to 126 mm., females to 93 mm. snout-vent length), high number of fourth-toe subdigital scales and femoral pores, and very high number of seales in fifteenth caudal verticil; dorsum tan, either unicolor or with moderately prom- inent greenish to yellow median and dorsolateral lines, lateral fields with exten- sive tan markings ( concolor with dorsum ) and black restricted to a series of irreg- ular blotehes or vermiculations; chest black, and throat with a posterior black patch. DISTRIBUTION: South-ccntral Las Villas Province, Cuba, from Paso Caballo and Soledad on the west to Trinidad and Casilda on the east. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts; snout-vent length 106 mm., tail 256 mm.; ventrals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales 42 and 40 (total 82); femoral pores 15 and 15 (total 30); 31 seales in the fifteenth caudal verticil. Dorsum tan, without a median line but with dorsolateral lines greenish and fairly prom- inent. Lateral fields obscure, consisting of an irregular blaek retieulum encroached upon by extensive tan markings, concolor with dorsum. Lower sides mottled greenish yellow. Venter bright blue (Pi. 33 K 4) laterally and pale blue centrally. Limbs tan dorsally, with some vague grayish markings; hindlimbs fleeked pale blue (Pi. 33 G 5). Tail tan above, grayish blue below; pale ventrolateral caudal stripe obseure. Chest black (including first 12 transverse rows of ventrals); throat with a large black patch or blotch, continuous across mesoptychium with black chest. Face suffused with reddish, most prominent on lips, around tympanic opening, and sides of neck. variation: The series of 65 A. a. atrothorax has the following counts: longitu- dinal ventrals 31-35 (mode 34); rows of transverse ventrals 10, 11 (1 specimen), or 12 (4 specimens); fourth-toe seales 72-91 (mean 79.0); femoral pores 21-32 (mean 26.8); fifteenth verticil 25-33 (mean 29.5). The largest male has a snout- vent length of 126 mm., the largest female 93 mm. A. a. atrothorax is a somewhat variable race as far as dorsal pattern is concerned. The dorsal ground color is always tan. The median and dorsolateral pale lines may be expressed or not in full adults, and their color is variable, from greenish (in the Trinidad region) to yellow (Paso Caballo). The lateral fields are likewise variable, although the black reticulum and much invasion of tan pigment into the lateral field area is the modal condition. At times the black pigment forms a sinuous and rather irregular line, or a series of rather vertically oriented short bars or spots. Only in juveniles is the lateral field extensively black. In adults from near Soledad the lateral fields are more prominent than 1970 Ameiva auberi: I. The Cuban Subspecies 81 they are in Trinidad specimens. The lower sides have been regularly recorded in life as greenish yellow or bluish green. The status of the black chest and throat pigmentation in both sexes may be summarized as follows. Thirty males (snout-vent length 65 mm. to 126 mm. ) and thirty females ( snout-vent lengths 55 mm. to 93 mm. ) were separated into four categories : ( 1 ) black chest and black throat patch fully developed; (2) black chest fully developed and small black throat patch; (3) black chest fully developed and only faint indication of black throat patch; (4) no black on chest or throat. Thirteen males (snout- vent lengths 72 mm. to 126 mm., and thus in- cluding the largest male) fall in the first category and thus have the complete complement of dark pigment. Ten males (snout-vent lengths 75 mm. to 108 mm. ) have the chest black and the throat patch partially developed. Four males (snout-vent lengths 70 mm. to 90 mm.) fall into category 3, and three males (snout-vent lengths 65 mm. to 82 mm.) lack any black pigment and fall into category 4. In summary, almost all males (one exception, snout-vent length 82 mm.) above 71 mm. have at least the chest black; the degree of development of the throat patch is variable but it is usually well expressed at snout-vent lengths above about 90 mm. Only one female (snout-vent length 60 mm.) falls in category 1, and only four females (snout-vent lengths 61 mm. to 93 mm.) fall into category 2. Eight females (snout-vent lengths 63 mm. to 87 mm. ) are regarded as being in category 3, and 17 females ( snout- vent lengths 55 mm. to 80 mm. ) lack any black pigment and are in category 4. In summary, development of black chest and throat in fe- males seldom reaches the extreme it does in males. Females in excess of 79 mm. are fairly consistent in having some black chest and throat pigment, whereas females below 68 mm. usually lack pigment on either chest or throat. The significance of these variations in each sex is no more open to solution here than in the previously discussed black- throated and black-chested subspecies. Although the juvenile dorsal color is tan as it is in adults, juveniles are purplish ventrally. This ventral coloration may persist into some subadult females as dull pink. COMPARISONS: In having a black chest and black throat spot (in contrast to an all-black throat), A. a. atrothorax is like A. a. piillata and A. a. extorris. The southern Las Villas subspecies reaches a much larger size ( 126 mm. in male atrothorax, 81 mm. in male pullata, 76 mm. in male extorris) than the two similar subspecies, has a tan dorsum (brown in pullata), and has the lateral fields present and prominent 82 Annals of Carnegie Museum VoL. 41 (absent in extorris). The very high mean number of scales in the fif- teenth caudal verticil in atrothorax (29.5) contrasts with the much lower means in pullata (26.8) and extorris (25.4). Similar mean differ- ences in fourth-toe scales (79.0 in atrothorax, 75.0 in pullata, 69.5 in extorris) are significant. The races atrothorax and pullata resemble each other in dorsal pattern ( either unicolor or with faint longitudinal lines), although the lines are usually greenish in atrothorax and yel- low in pullata. A. a. atrothorax differs from all other subspecies except denticola, in having a black chest and a black tliroat patch. A. a. atrothorax differs from denticola in having a black throat patch rather than the throat entirely black. REMARKS: In my experience, Ameiva is not especially common in the vicinity of Trinidad. Specimens were collected on the outskirts of the city along stone walls in short grass, and at Punta Casilda only a very few were seen along the boulder- strewn beach. The series from the type locality was taken in xeric scrub woods. The substrate was limestone outcroppings and rocks, imbedded in red earth (see Schwartz, 1959d:15 for description). Several sandy scrub areas along the coast between Trinidad and Cienfuegos were visited, but despite apparently suitable habitat, no Ameiva were observed. The fact that only a single specimen was collected in two days at Paso Caballo is significant. Hardy (1956:323) reported the occurrence of A. auberi on Cayo Macho de Tierra, about 10 miles southeast of the town of Casilda. No specimens were collected and the racial status of this population re- mains in doubt. These lizards may be assignable to atrothorax or may represent an endemic race on this small offshore islet. The known range of A. a atrothorax is removed about 120 kilometers i from that of the closest described subspecies, A. a. garridoi, in northern Las Villas Province. Although much of the area between these two races seems suitable for A. auberi, no specimens are known from this intervening region. In fact, no Ameiva have been collected along the south coast of Cuba between atrothorax and Cabo Cruz to the east, and, with the exception of the population next to be described at Juragua on the southern Las Villas coast, there are no Ameiva known to the west until one reaches Dayaniguas in Pinar del Rio Province. Thus A. a. atrothorax and the Juragua subspecies stand alone on the coast of central southern Cuba. 1970 Ameiva auberi: I. The Cuban Subspecies 83 Ameiva auberi peradusta, new subspecies holotype: IB 85, an adult male, from Juragua, Las Villas Province, Cuba, taken May 15, 1966, one of a series collected for Orlando H. Garrido. PARATYPEs: IB 86-90, CM 40643-40646, same data as holotype; ASF S V11166- V11170, NMC 9584 (4 specimens), MSB 374, 376-378, 380-381, 383-384, 387, same locality as holotype, April 27, 1965, M. S. Buide. diagnosis: a Cuban subspecies of A. auberi characterized by a combination of large size (males to 105 mm., females to 76 mm. snout-vent length), very high number of fourth-toe subdigital scales, high number of femoral pores and scales in fifteenth caudal verticil; dorsum grayish black in adults, without longitudinal lines, lateral fields terra cotta, v^th or without (usually) some included irregular markings or blotches; sides of head, neck, all of throat, under sides of both fore- limbs and hindlimbs, and almost all of venter, rich, lustrous black. DISTRIBUTION: Knowu only from the type locality on the west side of the Bahia de Cienfuegos, Las Villas Province, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 105 mm., tail 210 mm.; ventrals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales 44 and 43 (total 87); femoral pores 13 and 13 (total 26); 29 scales in the fifteenth caudal verticil. Dorsum dull grayish black, top of head dark grayish brown; no dorsal or dorsolateral lines. Lateral fields terra cotta in life with a few scattered and irregularly shaped black spots or flecks within the terra cotta band. Sides of head and neck, all of throat, under side of forelimbs and all of venter rich, lustrous black; under side of hind- limbs dark gray. Infralabials and sublabials blackish gray; snout reddish. Fore- limbs darker than hindlimbs above, the former concolor with the dorsum, the latter paler brownish gray with some scattered flecking. Lower sides blue-black, with some isolated blue flecks on the more lateral black rows of ventrals. Tail gray- brown above, blue-gray below; ventrolateral pale caudal stripe indistinct on basal third of tail, absent on distal two-thirds. VARIATION: The series of 28 A. a. peradusta has the following counts: longi- tudinal ventrals 32-36 (mode 33); rows of transverse ventrals 10 or 11 ( 1 speci- men); fourth-toe scales 70-87 (mean 79.9); femoral pores 23-33 (mean 27.2); fifteenth verticil 26-32 (mean 28.9). The largest male is the holotype with a snout-vent length of 105 mm.; the largest female has a snout-vent length of 76 mm. The series of A. a. peradusta is remarkably consistent in all details of color and pattern. The lateral fields may be less red than those describ- ed for the holotype, and in many preserved specimens the lateral fields are no longer evident. Such individuals lack any black flecks or blotches in the lateral field areas, and the dorsum and sides are unicolor grayish black to brownish gray. The black throat, venter, cheeks, and neck are constant features of males, regardless of size. Even the smallest male available ( CM 40644, snout-vent length 75 mm. ) is equally as black as the largest males. There are only three females. One of these (CM 40646, snout-vent length 71 mm.) has the throat and chest solid black, and there is incipient black and gray smudging over the rosy venter 84 Annals of Carnegie Museum VoL. 41 and on the underside of the forelimbs. This female is dark brown dor- sally with three greenish, almost fluorescent, lines. The lateral fields are unmarked brown, almost terra cotta, and the hindlimbs are dotted with black. A second female (CM 40645, snout-vent length 72 mm.) resem- bles males dorsally, lacks lateral fields, and has the black restricted to the throat and chest, with some black suffusion on the balance of the venter. In both sexes the pale ventrolateral caudal stripe and the trans- verse thigh line are inconspicuous. COMPAEISONS: A. a. peradusta is so very distinctive that it requires comparison with no other Cuban subspecies. The black cheeks, neck, throat, and venter distinguish it from all other known populations of A. auberi in Cuba. Its closest geographic ally is atrothorax, from which peradusta can be distinguished by the characters that separate it from all other subspecies. REMARKS: I am indebted to Sr. Garrido for his excellent notes on A. a. peradusta and to Sr. Buide for the gift of specimens in his private collection. Both these men were most impressed with the differences between peradusta and other Ameiva they had collected, and certainly peradusta is one of the most distinctive of all the subspecies of A. auberi, both Cuban and Bahamian. Juragua lies on the west side of Bahia de Cienfuegos. Although the mouth of the bay is very narrow, it effectively separates peradusta from atrothorax, which occurs in the vicinity of Paso Caballo on the east side of the mouth of the bay. Almost certainly, peradusta is a direct derivative of atrothorax, a derivative that has been isolated on the west side of the bay. As noted in the discussion of atrothorax, there are no Ameiva known to the west of peradusta until the occurrence of procer at Dayaniguas in Pinar del Rio Province. Possibly A, a. pera- diista will be found to be widespread along the southern coast between the Bahia de Cienfuegos and the Bahia de Cochinos. At this time there are no specimens from this entire southern area. Other than the ad- jacent atrothorax, the nearest known population to peradusta is gem- mea, some 1 10 kilometers to the north along the northern Las Villas coast.

DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 90 mm., tail 211 mm.; ventrals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales 42 and 39 (total 81); femoral pores 12 and 13 (total 25); 28 scales in the fifteenth caudal verticil. Dorsum brown with pale median and dorsolateral stripes evident but only fairly prom- inent; dorsal fields between median and dorsolateral stripes marked ( especially on posterior half of trunk, but visible anteriorly as well) with fine filigreed dusky gray marblings. Lateral fields broad and black, the black much restricted by about three longitudinal series of brown, subcircular spots, and bounded below by a prominent pale lateral line. Lower sides blue, marbled with dark gray. Ven- ter pale blue; throat pale (pale orange in life?). Tail brown above, pale grayish blue below; pale ventrolateral caudal stripes well developed on basal third of tail. VARIATION: The series of 13 A. a. llanensis has the following counts: longitudinal ventrals 31-34 (mode 34); rows of transverse ventrals 10; fourth-toe scales 68-81 (mean 73.5); femoral pores 21-26 (mean 23.8); fifteenth verticil 25-30 (mean 27,7). The largest male has a snout-vent length of 90 mm., the largest female 78 mm. The most distinctive dorsal feature of A. a. llanensis is the filigreed to boldly marbled dorsal fields. This is a common attribute of all spec- imens, regardless of size, but it is variable in intensity. Two old speci- mens from the city of Camagiiey (MCZ 7277 and 84917) show the dorsal markings most vividly, but perhaps this is due to the length of time these lizards have been in preservative, with consequent lighten- ing of the dorsal brown pigments, thereby rendering the dark markings more apparent. The lateral fields are always bold and very heavily spotted with two or three series of large ovoid or subcircular brown spots, which at times fuse with one another. In fresh specimens, the dorsal coloration is brownish. The median and dorsolateral lines are faint yellow and persist in adults. The venter is a very pale blue (al- most gray) centrally, and the lower sides and lateral-most rows of ventrals are darker blue to greenish. The throat is pale orange (PI. 11 86 Annals of Carnegie Museum VoL. 41 B 8 ) grading to pale yellow on the sides of the throat and on the sub- labials. The longitudinal stripe below the lateral fields is clear greenish in life. Although there are no juvenile specimens, small subadults (snout- vent lengths 61 to 65 mm., both sexes represented ) have the blotched dorsal fields as adults do. COMPARISONS: The blotched dorsal fields separate A. a. llanensis from all other subspecies of A. ciuberi, including the orange-throated races auberi, abducta, gemmea and extraria. In lateral field pigmenta- tion, llanensis most closely resembles gemmea, although these two sub- species are not close geographically. REMARKS: In the serpentine savannas of Camagiiey Province, Ameiva appears to be distinctly uncommon. Only eight specimens were secured by myself and parties in two lengthy visits to this region. All were taken on sandy soil or the gravelly and rocky hillocks that dot the area, and that are frequented as well by Leiocephalus sfictigaster ophipla- codes Schwartz. The vegetation where the Ameiva were collected was regularly short, sparse grass. The known range of A. a. llanensis encompasses only a small portion of the serpentine savannas that extend from central Camagiiey to north- western Oriente and are bounded on the north by the Sierra de Cubitas. A. a. llanensis is well removed from Ameiva to the west, with atrotho- rax the closest known subspecies at a distance of about 200 kilometers airline. Despite collecting at several stations between those two regions, no Ameiva has been observed. ADDITIONAL SPECIMENS It is appropriate here to mention ten specimens from Las Villas and Camagiiey provinces which are not racially assigned at this time. These include one subadult female (AMNH 6516) from the Sierra de Jati- bonico near the Camagiiey-Las Villas province line, and a series of nine specimens (AMNH 96410-96418) from 11.9 mi. N.W. Banao, Camagiiey Province. The first specimen is long preserved, but it is distinct from the two closest subspecies near the north coast — garridoi on the west and llanensis on the east — although neither of these is known to occur close to the Sierra de Jatibonico. The locality is nearer geographically to the range of atrothorax on the south, but the lizard does not appear to represent that subspecies. I leave it temporarily un- assigned subspecifically. The series from northwest of Banao was collected by myself and party in 1960. This locality is north of the Sierra de Cubitas ( in which 1970 Ameiva auberi: I. The Cuban Subspecies 87 range Ameiva is not known to occur), and the lizards were taken along a road through mesic lowland forest a quite different habitat from that occupied by llanensis to the south of the Cubitas. My color notes are not adequate to diagnose these specimens; they do differ from all other Las Villas and Camagiiey races (except gemmea and garridoi) in having pale yellow throats. The specimens resemble gemmea in lateral field and dorsal patterns but seem to lack the scattered yellow scales in the lateral fields, which is so distinctive a feature in gemmea. Since gemmea is separated from these Camagiiey specimens by the interposed range of garridoi, it seems unlikely that they represent the former subspecies. They might also be assignable to garridoi, but con- sidering the distance separating them from garridoi (about 250 kilo- meters), I doubt that they are correctly to be considered garridoi either. Additional material from this region will be necessary before the status of this population can be ascertained. Ameiva auberi sublesta, new subspecies holotype: AMNH 96393, an adult male, from Playa Bonita, east end, Cayo Sabinal, Camagiiey Province, Cuba, taken July 31, 1960, one of a series collected by Ronald F. Klinikowski, David C. Leber, and James D. Smallwood. Original number 9585. PARATYPES: AMNH 96392, 96394-96403, same data as holotype. DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of small size (males to 81 mm., females to 67 mm. snout-vent length) high number of fourth-toe subdigital scales, femoral pores, and scales in the fifteenth caudal verticil; dorsum tannish gray with gray-to-cream median line which expands and fades posteriorly; dorsolateral lines obscure to absent, lateral fields with black restricted to isolated small blotches or obsolescent grayish vertical bars because of intrusion of dark-brown edges of lateral fields; and throat brick red. distribution: Known only from Cayo Sabinal off the northern coast of Camagiiey Province, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 81 mm., tail broken and partially regenerated; ventrals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales 39 and 41 (total 80); femoral pores 12 and 13 (total 25); scales in fifteenth caudal verticil uncountable. Dorsum dull tannish gray without dorsolateral light lines; median dorsal line gray, expanding on midback and fading out posteriorly. Tail gray above, dull bluish gray below; ventrolateral pale stripe obscure. Lateral fields obscure, reduced to a few black or dark-gray flecks in an obsolescent brown stripe, not set off from either dorsal or lateral pigmentation by pale lines. Limbs dull brownish with very vague grayish markings. Belly dull bluish; throat brick red. VARIATION : The series of 12 A. a. sublesta has the following counts : longitudinal ventrals 32-34 (mode 33); rows of trai^verse ventrals 8 (1 specimen) -10; fourth- toe scales 69-84 (mean 77.6); femoral pores 25-28 (mean 26.3); fifteenth verti- 88 Annals of Carnegie Museum VoL. 41 cil 26-30 (mean 28.0). The largest male has a snout-vent length of 81 mm., the largest female 67 mm. The tannish gray dorsal coloration and gray-to-cream expanding and fading median dorsal line are common features of the series. In some specimens the lateral fields are more solidly black than in the holotype and have about two longitudinal series of subcircular brown dots. In other individuals of the same size these dots are coalesced and restrict the black pigment to spots of flecks on an otherwise brown ground. At best, the dorsolateral lines are faint and lack the distinctness of the median line; thus the lateral fields are not outlined in pale above. Both sexes have the throats brick red; the throats of males are more deeply pigmented (PL 3 I 12) than are those of females (PL 3 A 10). There seems to be no ontogenetic change in dorsal pattern and color, since a juvenile female with a snout-vent length of 45 mm. is comparable in these features to the adults. COMPARISONS: Of the described races, A. a. siihlesta most closely resembles the more western A. a. extraria. The brick-red throat of siih- lesta (the only subspecies with this feature) differs from the dull orange or gray tliroat of extraria, and the dorsal ground color of ex- traria is darker ( yellowish brown to reddish ) than the tannish gray of siihlesta. The median dorsal line that expands and fades out posteriorly is characteristic of a complement of eastern subspecies of A. aiiheri ( and occurs as well in extraria). It is obvious that the relationships of siih- lesta are with the eastern Camagiiey-Oriente subspecies rather than with races on the mainland to the west. Comparisons with these more eastern subspecies will be made below. REMARKS: As just uoted, A. a. suhlesia is doubtless derived from the eastern Camagiiey subspecies about to be described. The physical re- lationships of Cayo Sabinal to the mainland and the balance of the northern Camagiiey cayeria have been discussed elsewhere (Schwartz, 1964a: 216). The lizards were moderately abundant on Cayo Sabinal, and were collected in coastal scrub, along the beach, and on the mud in and about coastal mangroves. At most localities they were accom- panied by Leiocephalus stictigaster parasphex Schwartz. 1970 Ameiva auberi: L The Cuban Subspecies 89 Ameiva auberi citra, new subspecies holotype: AMNH 96375, an adult male, from 2 mi.

Smith; AMNH 96369-96373, 1 mi. E. Playa Santa Lucia, July 26, 1960, D. C, Leber, A. Schwartz. diagnosis: A Cuban subspecies of A. auberi characterized by a combination of moderate size (males to 93 mm., females to 72 mm. snout-vent length), high number of fourth-toe subdigital scales, low number of femoral pores, and mod- erate number of scales in the fifteenth caudal verticil; dorsum dull tan, median dorsal stripe lemon-yellow to pale tan, expanding and fading posteriorly, dorso- lateral lines absent or restricted to anterior half of trunk in adults, lateral fields variable from black with two or three longitudinal series of brick-red spots to completely obsolete, even in juveniles, and throat gray to faintly orange. DISTRIBUTION; Known only from the vicinity of Playa Santa Lucia, on the north coast of Camagiiey Province near the Oriente border, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 92 mm., tail 190 mm.; ventrals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales 39 and 38 (total 77); femoral pores 12 and 12 (total 24); 27 scales in fifteenth caudal verticil. Dorsum dull tan with a pale-tan median dorsal line which expands and fades out posteriorly; dor- solateral lines faint, tan, and restricted to anterior half of body. Tail dull grayish tan dorsally, bluish ventrally; ventrolateral pale caudal stripe moderately prom- inent on basal half of tail. Lateral fields black with a series of two brick-red spots along the upper and lower margins, the spots restricting the interior black to a series of irregular markings; lateral fields bordered below by a gray longitudinal stripe. Lower sides gray with a few darker vermiculations. Limbs dull tan above with a few vague darker marblings. Throat grayish orange; venter bluish. variation: The series of 31 A. a. citra has the following counts: longitudinal ventrals 31-35 (mode 32 or 33); rows of transverse ventrals 8 (2 specimens) • — 10; fourth-toe scales 67-89 (mean 77.2); femoral pores 20-29 (mean 24.3); fif- teenth verticil 24-29 (mean 25.8). The largest male has a snout-vent length of 92 mm., the largest female 72 mm. The most variable feature of A. a. citra is the condition of the lateral fields. In some individuals the lateral field is a solid black band with a minimum of brick-red “frosting” scales along its edges. At the other extreme is the condition described for the holotype. Some specimens also seem to lack the lateral fields entirely except for a reddish-brick-to- brownish area along each side. None of these conditions is correlated with size, and all occur in adults, subadults, and juveniles. The throats vary between gray and orange (PI. 9 B 7) and are never bright. 90 Annals of Carnegie Museum VoL. 41 Although my notes do not so indicate, presumably the brighter color is that of the males. The median dorsal stripe is pale tan to lemon-yellow, with the brighter shades in subadults. The belly varies from purplish in juveniles to bluish in adults and is not bright. COMPARISONS: A. a. citra, in having a gray-to-orange throat, is easily differentiated from those subspecies with throats that are black or have a black spot ( denticola, pullata, extorris, atrothorax ) , and those that have the throat colored other than orange ( procer, paulsoni, abducta, garridoi, sublesta). Of these, sublesta is the closest geographically. From all described subspecies except extraria and sublesta, citra differs in having the median dorsal line expanded and disappearing posteriorly. The median stripe is pale tan to lemon-yellow in citra, gray to cream in sub- lesta, and pale yellow in extraria. The dorsal ground color is yellowish brown to reddish in extraria, tannish gray in sublesta, and dull tan in citra. REMARKS: A. a. citra is obviously closely allied to its neighbor on Cayo Sabinal, A. a. sublesta; the ranges of the two are separated only by a narrow channel. As pointed out previously, sublesta and citra show a style of dorsal pattern that occurs from northeastern Camagiiey eastward along much of the Oriente coast. At and about Play a Santa Lucia, A. a. citra was moderately abundant, occurring in coastal scrub, along the mangrove border, in small man- groves on a rocky substrate, along the beaches (where the lizards were distinctly less common than in habitats behind the beach ) , and the arid woods near Punta Practices where they were taken in Eugenia thickets. Although the range of A. a. citra is apparently circumscribed, the race is presumably distributed farther to the east, at least along the Oriente coast. The Oriente style of dorsum does not occur on the mainland to the west of Playa Santa Lucia, since the specimens from the north coast of Camagiiey north of the Sierra de Cubitas already noted possess longitudinally lined dorsa without suppression of the dorsolateral lines characteristic of the more central and western subspecies. The closest named population to the west of citra is llanensis (removed 95 kilo- meters airline), and the unnamed population north of the Sierra de Cubitas lies at about the same distance from citra. Despite two long visits to Playa Santa Lucia and extensive collecting to the south of that resort, no Ameiva were seen in what appeared to be suitable habitats. Much of the country to the south of Playa Santa Lucia is cut-over xeric forest, a habitat these lizards often occupy. 1970 Ameiva auberi: I.

ASSOCIATED SPECIMENS (all from Oriente Province, Cuba): USNM 80415, IB 17, IB 19-30, ASFS V11384-V11388, Gibara. diagnosis: A Cuban subspecies of A. auberi characterized by a combination of moderate size (males to 93 mm., females to 82 mm. snout-vent length), mod- erate number of fourth-toe scales and femoral pores, and low number of scales in the fifteenth caudal verticil; dorsum reddish tan in adults, dark brown in sub- adults and juveniles, median dorsal stripe yellow, expanding and fading posteriorly and continuing onto tail as a distinctly defined gray median caudal zone, dor- solateral lines yellow and often irregular or fragmented, outlining lateral fields which are extensively black with small red scallops or isolated dots, and chest and throat black ( see, however, discussion ) . distribution : The north coast of Oriente Province, Cuba, from Banes ( and possibly as far west as Gibara) on the west to the vicinity of Baracoa on the east. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 93 mm., tail 166 mm., incomplete; ventrals in 32 longitudinal and 10 transverse rows; fourth-toe subdigital scales 36/-; femoral pores 13 and 14 (total 27); 26 scales in fifteenth caudal verticil. Dorsum reddish tan with paler tan median line which expands and fades posteriorly and becomes a sharply distinct gray dorsal band ( about four scales wide ) on the upper sur- face of the tail; sides of tail black, admixed with tan scales basally, the black fading to darker gray distally; caudal ventrolateral pale stripe conspicuous basally but becoming dim distally. Lateral fields extensively black, bounded above by a rather irregular or slightly sinuous tan line, the fields with an upper and lower series of red spots ( at times joined to the lateral green stripe below the lateral fields). Sides greenish and heavily tigroid with dark gray. Limbs reddish tan above with rather heavy gray vermiculations. Throat and chest (to about level of fourteenth transverse row of ventrals) black; venter bluish gray, slightly brighter on under side of tail. variation: The series of 57 A. a. granti (including material from Gibara) has the following counts: longitudinal ventrals 31-34 (mode 32); rows of transverse 92 Annals of Carnegie Museum VoL. 41 ventrals 9 (1 specimen) -10; fourth-toe scales 63-92 (mean 75.9); femoral pores 21-31 (mean 25.7); fifteenth verticil 22-29 (mean 25.1), The largest male has a snout-vent length of 93 mm., the largest female of 82 mm. The material from Gibara, here assigned tentatively to granti, will be discussed separately below. Except for the Gibara specimens, A. a. granti is fairly constant in all chromatic characters throughout its rela- tively long range. The dark dorsum with yellow ( to tan in subadults and juveniles) expanding and fading middorsal line, which in turn gives rise to the sharply delineated gray upper surface of the tail, bounded laterally by the black sides of the tail, is a common feature. The ventro- lateral white caudal stripe is also prominent and serves to delimit sharply the black lateral faces of the tail below. As usual, the lateral fields are somewhat variable, but they usually have irregular edges and some sort of scalloping or spotting. Very rarely are they solid black as in some ‘ southern Oriente populations. The tail is blue in young adults and : juveniles. Ameiva a. granti shows the by-now rather familiar black chest of the black-throated races of A. auheri; however, except for the Gibara speci- mens, the situation in male granti is diagrammatic. All (26) males with snout-vent lengths above 67 mm. have the throat and chest solid black, and at times the black pigment extends far posteriorly onto the belly. Only a single subadult male (60 mm. snout-vent length) has the chest black and a dark gray (rather than black) throat. The situation in females is not so clear. The females fall into three categories. Only two specimens have a completely black throat and chest ( category 1 ) . These have snout-vent lengths of 58 mm. and 77 mm. Eight females have a black chest and gray throat (category 2). These range in snout-vent length from 55 mm. to 82 mm. and include the largest female. Seven females that lack any black pigment on either chest or throat ( category 3) have snout-vent lengths of 58 mm. to 72 mm. Thus the females that lack black pigment are bracketed on both sides by females with solid black or gray areas. The occurrence of solid black chests and throats in two females is unusual. Both of these were taken in December. The 58 mm. female without black pigment was collected in April. April-taken females with gray throats and black chests include two specimens with snout-vent lengths of 64 mm. and 72 mm. Although I include the Gibara series with A. a. granti, I do so with some misgivings. I have not seen Gibara lizards in life, but the excellent lot, collected by Sr. Garrido, from that area is fresh. Sr. Garrido has also supplied me with a color diagram and color slides of these Gibara lizards. Dorsally, these lizards do not violate my concept of granti except 1970 Ameiva auberi: I. The Cuban Subspecies 93 that the median dorsal stripe is very pale tan, almost cream, and the dor- solateral pale lines are not fragmented. The lateral fields agree in detail with granti from farther east. My hesitancy in regarding them (with complete certainty) as granti arises from the throat condition: of the series of 18 fresh Gibara lizards, all but one have pale orange throats, whereas that exceptional lizard (a male with a snout-vent length of 67 mm), has a black chest and very large black throat spot (but the entire throat is not black as in granti males at 67 mm.). The single old Gibara specimen (USNM 80415, a female, snout-vent length 64 mm.) agrees with the fresh material in lacking a black throat. I suspect that these lizards are either still another (orange-throated) subspecies on the northern Oriente coast or represent extreme inter- grades between granti to the east and an orange-throated subspecies farther west. The nearest unquestioned granti locality is Banes, 50 kilo- meters to the southeast. The nearest known population along the coast to the northwest is citra at Playa Santa Lucia, about 68 kilometers dis- tant. Since citra has a gray-to-orange throat, it is possible that the Gibara lizards are granti x citra intergrades, but this section of Oriente coast is so poorly known that it seems imprudent to regard them as such at this time. COMPARISONS: The only previously described subspecies of A. auberi with solid black chests and throats are denticola, far to the west in Pinar del Rio Province, and per adust a in Las Villas Province. A. a. denticola and A. a, granti differ in many features, but the most striking are the expanding and fading median dorsal line and the gray band, bordered by black sides, on the upper surface of the tail in granti. A. a. granti differs from peradusta in lacking the black cheeks and neck and com- plete venter, and in being patterned dorsally. These two subspecies also differ markedly in mean number of fifteenth verticil scales (25.1 in granti, 28.9 in peradusta); granti ranks low and peradusta high in this character. The dorsal chromatic details (coupled with the darker red- dish tan dorsum) will also serve to differentiate granti from all previ- ously described subspecies. The dorsal coloration and pattern of extraria is somewhat comparable to that of granti, but the inconspicuous and brown lateral fields in extraria are distinct from the conspicuous lateral fields of granti. REMARKS: A. a. granti is based in part on the long series collected by Major Chapman Grant at Banes. It is indeed a pleasure to associate his name with such a very distinctive subspecies, of whose existence he was well aware ( Grant, 1960 ) . Recently taken specimens have been secured 94 Annals of Carnegie Museum VoL. 41 on diente de perro limestone with some trees and shrubs, Bahia de Miel), in shoreline vegetation both along the coast (northwest of Bahia de Taco) and in mesic riverine growth (Rio Bay). To the south, much of the range of granti is bordered by the Oriente massifs, and these mountain masses separate granti from the races on the soulh coast of the province, although I suspect that granti intergrades with the easternmost southern Oriente subspecies between Baracoa and Cabo Maisi. The granti from La Poa indicate that these lizards penetrate the northern slopes and foothills of the Cuchillas de Toa southwest of Baracoa to some extent. There are no specimens from the serpentine savannas in the region about Holguin; it would be most interesting to learn what subspecies occurs in this interior region — either granti (expected on the basis of proximity of range) or llanensis (expected because of similarity and continuity of habitat ) . The Gibara lizards may represent a marginal sample, in part intergradient with granti, of a distinctive subspecies inhabiting these interior Oriente plains.

DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of small size (males to 80 mm., females to 66 mm. snout-vent length), low number 1970 Ameiva auberi: L The Cuban Subspecies 95 of fourth-toe subdigital scales, high number of femoral pores, and low number of scales in. the fifteenth caudal verticil; dorsum pale tan (sandy) to pale brown with median line pinkish anteriorly and gray posteriorly, fading and expanding posteriorly and continuing onto tail as a distinctly defined median gray caudal zone, dorsolateral lines tan and more or less straight, outlining lateral fields which are solid black (rarely with only a bare indication of reddish stippling along their margins), and chest and throat black. distribution: The southeastern coast of Oriente Province, Cuba, from the vicinity of the city of Guantanamo and Boqiieron, east to Cajobabo, and probably as far as Cabo Maisi. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 77 mm., tail 150 mm., partially regenerated; ven- trals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales 34 and 35 (total 69), femoral pores 14 and 15 (total 29), 25 scales in fifteenth caudal verticil. Dorsum very pale sandy tan with a pale (pinkish anteriorly, gray pos- teriorly ) median stripe, which fades and expands posteriorly and becomes a sharply distinct bluish gray dorsal zone ( about four scales wide ) on the upper surface of the tail; sides of tail black, admixed with grayish scales basally, the black fading to darker gray distally; ventrolateral caudal pale stripe prominent on unregenerated portion of tail. Lateral fields solid black, bounded above and below by fairly prominent pale tan (above) or pale gray (below) lines, and with a faint stippling of reddish-to-tan scales, especially along the posterior margins of the fields. Sides grayish, marbled with darker gray vermiculations. Limbs sandy gray above with vague darker gray marblings. Throat, chest (to about level of fourteenth transverse row of ventrals), and anterior faces of forelimbs solid black. Venter pale bluish gray, paler on underside of tail. variation: The series of 47 A. a. sabulicolor has the following counts: longi- tudinal ventrals 30-34 (mode 32); rows of transverse ventrals 10; fourth-toe scales 62-81 (mean 72.8); femoral pores 23-31 (mean 26.7); fifteenth verticil 22-29 (mean 25.6). The largest male has a snout-vent length of 80 mm., the largest female 66 mm. A. a. sabulicolor is one of a series of three races along the southern coast of Oriente Province between Cabo Maisi and Cabo Cruz. Its habi- tation of the most arid portion of this southern coast is reflected in its pallid coloration, varying from sandy or pale tan to pale brown. In juveniles and subadults the dorsum is somewhat darker brown than in full adults. The pink, grading to gray, median dorsal stripe and the tan dorsolateral stripes are constant features. In young specimens the lateral fields are solid black, and in adults there is only the barest indication of reddish-to~tan stippling along the very edges of the fields, especially in the posterior half. At times the lower sides have an additional longitudi- nal zone of tan paralleling the line that borders the lateral fields ven- trally. The black chest and throat are once again variable features. Specimens of sabulicolor were divided into three categories : ( 1 ) black chest and 96 Annals of Carnegie Museum VoL. 41 throat; (2) black chest and some black on throat; (3) pale chest and throat. Of 38 males, 19 ( snout-vent lengths 55 mm. to 80 mm. and thus including the largest male) fall into category 1. Category 2 includes eleven males with snout-vent lengths of 52 mm. to 74 mm., and category 3 includes eight males with snout-vent lengths from 50 mm. to 74 mm. Most (29 of 35) males with snout-vent lengths greater than 55 mm. have black chests and some indication of black on the throats. No females fall into category 1. In category 2 there are four females (snout-lengths between 50 mm. and 65 mm. ) and in category 3 ten females ( snout-vent lengths 52 mm. to 67 mm.). The smallest female has a black chest and some black on the throat, whereas many of the larger females ( including the largest) lack any black pigment. The situation is inconclusive. COMPARISONS: A. a. sabulicolor most resembles the races granti and citra from the northern coast of Camagiiey and Oriente provinces. A. a. sabulicolor differs from both these northern subspecies in being much paler dorsally, and it differs additionally from citra in having a black throat and chest rather than a gray-to-orange throat. Sabulicolor differs as well in having solid black lateral fields (with at best some faint red- dish stippling posteriorly), whereas both citra and granti regularly have some markings within the field itself. Both extraria and sublesta agree with sabulicolor in having an expanding and fading median dorsal line, but the throat in extraria is gray-to-diffuse orange, and brick-red in sublesta. The southeastern coast of Oriente is typical of the arid tropics, and lies in the rain shadow of the Sierra de Burial and the Cuchillas de Toa and associated uplands. Although A. a. sabulicolor is primarily coastal, it does occur inland as far as the city of Guantanamo and north of the village of Cajobabo in the extreme eastern portion of its range. This latter locality is on the southern slopes of the Sierra de Burial and, although somewhat more mesic than the coast itself, is nonetheless arid. The elevation is probably less than 1000 feet. Ameiva was taken along the coast in such habitats as coastal scrub and arid woods, but in general the race appears not to be exceptionally abundant. The series from the United States Naval Base is the result of many years’ collecting, and no single collector has secured large numbers of specimens there. The range of A. a. sabulicolor is separated from that of A. a. granti by the interior Oriente massifs. As noted previously, I suspect that sabuli- color inhabits the xeric Cabo Maisi, and intergradation between it and granti occurs between Cabo Maisi and the region about Baracoa. Since the north Oriente coast is mesic, it seems likely tliat sabulicolor (which 1970 Ameiva auberi: I, The Cuban Subspecies 97 inhabits the xeric southern coast) occurs on Cabo Maisi, rather than granti (which occupies the mesic north coast).

DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of small size (males to 78 mm., females to 68 mm. snout-vent length), low number of fourth-toe subdigital scales, high number of femoral pores, and moderate number of scales in the fifteenth caudal verticil; dorsum brown with a yellow-to- gray median line, not (or only slightly) expanding posteriorly, remaining distinct, and forming a narrow dorsal stripe on the base of the tail which expands to form a broad dorsal caudal stripe, bounded laterally by black sides; dorsolateral lines gray to tan and prominent, outlining the solid black lateral fields above; lateral fields outlined below by a prominent tan-to-pale-gray lateral stripe, and chest and throat black. DISTRIBUTION: Southern coast of Oriente Province between the Bahia de San- tiago and the Bahia de Guantanamo, and occurring inland to the northwest of Santiago de Cuba at San Luis, El Cobre, and Palma Soriano, Cuba. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements 98 Annals of Carnegie Museum VoL. 41 and counts: snout-vent length 78 mm.; tail 126 mm., distal half regenerated; ven- trals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales 41 and 40 (total 81); femoral pores 13 and 14 (total 27); 27 scales in fifteenth caudal verticil. Dorsum brown with a prominent yellow median line which becomes gray at midbody, expands only slightly posteriorly, and forms a narrow, gray stripe (involving three scales) on the base of the tail, and then expands to form a rather broad, gray dorsal stripe on the unregenerated portion of the tail; caudal stripe bordered laterally by black sides of tail, which are basally much marked with tan to brown; ventrolateral caudal stripe white and very bold on unregen- erated portion of tail. Lateral fields solid black bordered above by tan dorsolateral stripes and below by pale gray lateral stripes; a few small circular reddish spots in the lateral fields above the forelimb insertion and above the groin. Limbs brown above with vague gray marbling; posterior face of thighs with a bold white horizontal stripe bordered both above and below by coarse black-to-dark- gray vermiculations. Belly very pale blue; throat black, but not completely so. VARIATION: The series of 85 A. a. iistulata has the following counts: longitudinal ventrals 30-36 (mode 32); rows of transverse ventrals 10; fourth-toe scales 64-85 (mean 72.8); femoral pores 22-32 (mean 26.2); fifteenth verticil 22-31 (mean 25.8). The largest male has a snout-vent length of 78 mm., the largest female 68 mm. The description of the coloration and pattern of the holotype suffices for most of the series of A. a. ustiilata, which, considering the large amount of material, is remarkably constant. The median dorsal line in many specimens shows no posterior expansion and is merely a median dorsal line, prominent and of the same width throughout its entire length. If there is posterior expansion, it is never so striking as in the races to the north and east. The lateral fields are solid black and very seldom show any included markings, the type being unusual in this respect. The two specimens from south of Palma Soriano have the lateral fields with scalloped edges. This may be the result of the influence of the next sub- species to the west (although the Palma Soriano specimens are not coastal ) , or the scalloped edges may represent the effect of some interior subspecies, as yet unsampled, from the valley of the Rio Cauto. The Palma Soriano specimens were taken from the rather low pass that crosses the Sierra Maestra between Palma Soriano and Santiago de Cuba. The posterior thigh markings in the holotype of ustulata are not shown so boldly in all specimens, but there is always at least a fairly clear white transverse bar with some darker markings above and below. There is little or no difference in pigmentation and pattern between juveniles and adults, although all pattern elements seem a bit better defined in young individuals. When all specimens of ustulata are categorized, the following data on black throats and chests may be summarized. In category 1, which 1970 Ameiva auberi: I. The Cuban Subspecies 99 includes all specimens with black throats and chests, are included 29 males with snoutwent lengths from 55 mm. to 74 mm. In category 2 ( chest black or with small black throat patch ) are 15 males with snout- vent lengths from 55 mm. to 78 mm., and thus including the holotype — the largest male. In category 3 ( no black on throat or chest ) are 15 males with snout-vent lengths of 52 mm. to 74 mm. Most males (39 of 45) with snout-vent lengths in excess of 60 mm. have some black on the chest or throat. A single female ( snout-vent length 58 mm. and thus not the largest female) falls into category 1. Only three females (snout-vent lengths 54 to 67 mm. ) fall into category 2, whereas 26 females ( snout- vent lengths 48 to 68 mm. ) lack any black on chest or throat. In general, only rarely do female ustulata achieve any black pigmentation on throat or chest, although occasional specimens do so. COMPARISONS: A. a. ustulata is obviously related to the more eastern sahtilicolor but differs from it in being darker dorsally (pale tan and pale brown versus brown), in having the median dorsal line not fading and expanding posteriorly, and in having a rather clear-to-bold trans- verse thigh stripe. The condition of the median dorsal line in ustulata will differentiate it from the other eastern subspecies {granti, citra, sub- lesta ) and the more western extraria, which have an expanding and fad- ing median stripe. Of these, extraria, stihlesta, and citra do not have black throats and chests. In some ways ustulata is rather like the far western paulsoni, but the black throat, gray median stripe, and black- sided and gray-surfaced tail of the former contrast with the cream throat, yellow lines, and unicolor tail of the latter. In the east, the shade of the median dorsal line differentiates citra (lemon-yellow to pale tan) from sabulicolof ( pinkish to tan ) and ustulata ( pale yellow to gray ) , but not from granti, which also has the line pale yellow to gray. REMARKS: A. a. ustulata is one of the few subspecies of A. auberi that occurs any significant distance inland and at any appreciable height. Comments have already been made on the specimens from Palma Sori- ano. The specimens from San Luis and El Cobre are from interior localities, and El Cobre is in a moderately high basin in the extreme eastern end of the Sierra Maestra (or in the Sierra del Cobre as it is locally known). San Luis lies in the Valle Central between the valley of the Rio Cauto to the west and the Cuenca de Guantanamo to the east The elevation of San Luis is only 171 meters (Marrero 1951:618). The Valle Central lies north of the Sierra Maestra (and north of the Sierra de Boniato and the Sierra de la Gran Piedra, which are Sierra 100 Annals of Carnegie Museum VoL. 41 Maestra affiliates) and south of the Sierra de Nipe and the eastern ' Alturas de Baracoa. The major portion of the range of A. a. ustulata lies to the south of ^ the Sierra de la Gran Piedra and in its coastal rain shadow. The coast between the Bahia de Santiago and the Bahia de Guantanamo is arid, but somewhat less so than the coast to the east of Guantanamo. Ground lizards were collected in coastal scrub and in moderately moist gallery ’ forest along the intermittent water courses near the coast. At Playa Juragua, Aguadores, and Laguna de Baconao, Ameiva was abundant in shady woods, as well as along the borders of mangroves at the last- named locality. The Bahia de Guantanamo separates the ranges of A. a. ustulata and A. a. sahulicolor, and the Bahia de Santiago separates the range of A. a. ustulata from the race to the west. The effect of these two bays upon populations of reptiles along the southern Oriente coast has been demon- strated by Schwartz (1960) in Leiocephalus raviceps and by Thomas ' and Schwartz ( 1966 ) in Sphaerodactijlus torrei. It is not surprising that A. atiberi, which also has an essentially coastal distribution in this area, | has differentiated into three distinct subspecies in southern Oriente.

DIAGNOSIS: A Cuban subspecies of A. auheri characterized by a combination of moderate size (males to 93 mm., females to 76 mm.), high number of fourth-toe subdigital scales, moderate number of femoral pores, and low number of scales | in the fifteenth caudal verticil; dorsum tan with pale-yellow-to-cream dorsal and dorsolateral lines, the median line expanding (although often not broadly) pos- teriorly and remaining distinct, lateral fields black with prominent red scallops and often with an included series of red spots, and throat orange. DISTRIBUTION: Southwestern coast of Oriente Province, Cuba, from the vicinity of Cabo Cruz on the west presumably to the Bahia de Santiago on the east, but specimens are lacking from the area immediately to the west of the bay. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 93 mm., tail 201 mm.; ventrals in 32 longitudinal and 10 transverse rows; fourth-toe subdigital scales 39 and 38 (total 77); femoral , pores 12 and 12 (total 24); 24 scales in the fifteenth caudal verticil. Dorsum | 1970 Ameiva auberi: I. The Cuban Subspecies 101 tan with a prominent median cream dorsal line, narrow anteriorly and wider (but not extremely so) posteriorly, extending onto the upper surfaces of the tail as a narrow dorsal blue stripe basally, and somewhat broader (four scales) posteriorly; a pair of dorsolateral tan lines above the lateral fields. Lateral fields extensively black and with large, reddish scallops ventrally, and irregular, reddish markings along the upper border; lower border of lateral fields with a faint grayish longi- tudinal line. Sides of tail black, sharply limiting the blue upper surface of the tail; ventrolateral caudal pale stripe prominent on the basal half of the tail. Lower sides extensively dark gray with some paler gray punctuations. Venter blue, under side of tail paler blue; throat very pale blue-gray in preserved specimen, but presumably pale orange in life. Upper side of limbs tan with little indication of darker marbling; no white transverse stripe along posterior border of thighs. VARIATION: The series of 15 A. a. hardyi has the following counts: longitudinal ventrals 30-34 (mode 33); rows of transverse ventrals 10; fourth-toe scales 73-83 (mean 77.8); femoral pores 21-30 (mean 24.8); fifteenth verticil 24-29 (mean 25.6). The largest male has a snout- vent length of 93 mm., the largest female 76 mm. I have seen but two examples of A. a. hardyi in life. One of these (AMNH 83777) is a juvenile on which I have no color data. The other (AMNH 83761) is from the extreme western end of the range at Cabo Cruz. Since the holotype and paratypes from between Cabo Cruz and west of Santiago are not black-throated, and since neither of the two specimens I have collected are black-throated (their throats were pale orange) I am assuming that all material from this stretch of coast is chromatically identical. Color slides and diagrams of specimens from Verreon, supplied by Sr. Garrido, confirm that the lizards at that locality are orange-throated. In general, material from farther west (Cabo Cruz and Rio Puercos) has the median dorsal line more expanded than most specimens from the type locality, but even lizards from the Ocujal area have the dorsal line more expanded posteriorly than do specimens of ustulata. The lateral fields invariably are marked with reddish along both borders; one individual has an included longitudinal series of red- dish dots in addition to the marginal scallops. Another specimen has a rather restricted series of ventral scallops. Even in the smallest specimen (snout-vent length 41 mm.) there are red markings within the lateral fields. No specimen shows any indication of black on the throat or chest. COMPARISONS: The combination of orange throat and expanded median dorsal line separates hardyi from all other subspecies of A. auberi except possibly citra on the north coast of Camagiiey and extraria on the northern cayeria in Las Villas. Ameiva a. hardyi may be distinguished from the latter in having all dorsal pattern elements much more distinct, in having a darker dorsal ground color, and in having prominent lateral fields. Ameiva a. hardyi differs from citra in having prominent lateral 102 Annals of Carnegie Museum VoL. 41 fields and the tail with black sides restricting a dorsal blue stripe. Hardyi differs in its larger size from its neighbor ustulata on the east (even though the series of ustulata is six times the size of the hardyi sample, none of the former in any way approaches the larger size of the 15 specimens of hardyi) in having an orange rather than black throat, and in other details of dorsal pattern and pigmentation. REMARKS: A. a. hardyi is limited in distribution to the xeric coast south of the Sierra Maestra system between the Cabo Cruz region and Santi- ago de Cuba ( the eastern portion of the range is hypothetical since there are no specimens from close to the Bahia de Santiago). At the type locality. Cooper (1958:13) reported securing specimens of A. auberi in the southern foothills of the Sierra Maestra as he and his party climbed toward Pico Turquino. The Ocujal region itself is arid. The AMNH specimen from Cabo Cruz was collected in a beach scrub habitat, and the lizard from 18.6 mi. west of Santiago de Cuba was from a similar situation. Many of the specimens of A. a. hardyi are from the vicinity of the type locality and were collected through the efforts of Jerry D. Hardy, for whom the subspecies is named. Although there are no specimens of hardyi from close to the Bahia de Santiago to the west, it is possible that hardyi and ustulata intergrade somewhere about the western side of the bay. As noted in the discussion of ustulata, the two specimens from south of Palma Soriano differ some- what from most ustulata. One, the largest specimen of that race, is a black-chested male. Both have extensive reddish markings in the lateral fields. If these specimens are hardyi x ustulata intergrades, then hardyi must somewhere avoid the eastern periphery of the Sierra Maestra to reach the Palma Soriano region. As previously stated, it is also possible that these two lizards are intergradient between ustulata and some sub- species to the north, rather than being hardyi x ustulata intergrades.

DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of moderate size (males to 92 mm., females to 77 mm. snout-vent length), low number of fourth-toe subdigital scales, moderate number of femoral pores, and very low number of scales in the fifteenth caudal verticil; dorsum brown to red- dish brown with prominent median and dorsolateral longitudinal yellow lines, lateral fields usually extensively black with scattered and isolated red dots, and throat black. DISTRIBUTION: The northern two-thirds of the Isla de Pinos, north of the Cienaga de Lanier. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 82 mm., tail 212 mm,; ventrals in 32 longitudinal and 10 transverse rows; fourth-toe subdigital scales 35 and 36 (total 71); femoral pores 12 and 13 (total 25); 26 scales in the fifteenth caudel verticil. Dorsum reddish brown with median and dorsolateral lines yellow and very bold. Lateral fields black with two longitudinal series of discrete red dots, and bordered below by a bold, grayish yellow line. Lower sides pale bluish gray with dark vermicula- tions. Limbs reddish brown above, heavily marbled with very dark brown; a clear white transverse line on the posterior face of the thigh, bordered above and below by wide black bands. Throat black, with very httle black pigment extend- ing onto first two or three transverse rows of ventrals. Tail grayish brown above, with a pair of whitish dorsolateral lines on its basal half; sides of tail dark gray or black, not clearly demarcating a dorsal paler longitudinal band; ventrolateral white caudal stripes distinct on basal half of tail. Belly dull grayish blue, under side of tail dark blue-gray. VARIATION: The series of 57 A. a. secta has the following counts: longitudinal ventrals 29-34 (mode 31); rows of transverse ventrals 8 (5 specimens) -10; fourth-toe scales 63-86 (mean 69.6); femoral pores 21-31 (mean 24.8); fifteenth verticil 22-28 (mean 24.9). The largest male has a snout-vent length of 92 mm., the largest female 77 mm. The dorsal color of A. a. secta varies from brown to rich reddish brown, and the median and dorsolateral lines are yellow and prominent at all ages. The lateral fields are somewhat variable as is customary. 104 Annals of Carnegie Museum VoL. 41 They are always extensively black and usually have some included red markings, often, as described in the type, a series of discrete red spots. In some individuals the lateral fields are almost solid black, with some faint reddish stippling along the upper and lower margins, and some have the margins of the fields scalloped with reddish. The ventrolateral caudal pale stripes are bold, but only occasional individuals show any indications of white dorsolateral caudal stripes as does the holotype. There is often a bold black lateral line on the tail, delimited below by the ventrolateral caudal stripe and above by the dorsolateral caudal stripe (if present). The bold white transverse thigh stripe, surrounded on both sides by black patches, is fairly constant. The series of A. a. secta was separated into three categories on the basis of chest and throat pigmentation: (1) black chest and throat; (2) black spot on chest and small black patch on throat; (3) no black on chest or throat. Of 32 males, 17 ( snout-vent lengths 54 mm. to 92 mm., including the largest and smallest males) fall into category 1. Eleven males (snout-vent lengths 61 mm. to 91 mm.) are grouped in category 2, and only four males (snout-vent lengths 57 mm. to 65 mm.) are in category 3. Thus, most males (28 of 32), with snout-vent lengths of 54 mm. or more, have the chest black and some black on the throat. Of 27 females, two (snout-vent lengths 56 mm. and 75 mm.) are as heavily pigmented on tliroat and chest as most of the males, and fall into cate- gory 1. Four females (snout-vent lengths 57 mm. to 77 mm. and thus including the largest female ) are included in category 2. Twenty females with snout- vent lengths from 52 mm. to 67 mm. lack any black on throat or chest and are in category 3. Once again, the situation with black throats and chests is anomalous. It can be stated at least that even small females at 56 mm. may achieve the totally black throat and chest of most males, but many larger females seem not to have reached this condition. COMPARISONS: Of the Cuban mainland races, A. a. secta most closely resembles (as might be expected) A. a. paulsoni, which is geographic- ally the most closely adjacent race. The two may be distinguished from each other by the cream throat and lateral field pattern (black with ventral margin scallops only) of paulsoni in contrast to the black throat and more variably patterned lateral fields of sectq. The close relationship of the two races is shown by the low means of fourth toe scales ( 68.6 in paulsoni, 69.6 in secta ) . Ameiva auberi secta is unique among Cuban subspecies in having a boldly lined brown or reddish brown dorsum without an expanding median dorsal line, and a black throat. 1970 Ameiva auberi: I. The Cuban Subspecies 105 REMARKS: A. a. secta is widespread in many habitats, both interior and coastal, on the northern two-thirds of the Isla de Pinos. It was col- lected near Santa Fe on Malpais gravel in pinelands. coastally along beaches among Ipomaea (near Siguanea), in grass and cut mangrove trash (Buena Visita), and in broadleaf forest (Bibijagua). On two occasions we observed birds preying upon A. a. secta. Both episodes were diurnal and occurred at Playa de Buena Visita in cut-over man- groves adjacent to the coast. The predators were the Sparrow Hawk (Falco sparverius sparverioides) and Cuban Pygmy Owl (Glaucidium siju vittatum). In both cases, the birds swooped down to the ground and returned to perch clutching a subadult Ameiva. The relationships of A. a. secta with the southern Isla de Pinos sub- species will be discussed below.

Garrido. diagnosis: A Cuban subspecies of A. auberi characterized by a combination of moderate size (males to 87 mm,, females to 77 mm. snout-vent length), moderate number of fourth-toe subdigital scales and femoral pores, and low number of scales in the fifteenth caudal verticil; dorsum brown to tan with heads gray, me- dian and dorsolateral lines tan, the median line very obscure, lateral fields black with brown included edging and consequent reduction of the black pigment, and throats pale blue (or with some black pigment; see discussion). distribution: The southern third of the Isla de Pinos, south of the Cienaga de Lanier, but including the Paso de Piedras which joins the north and south portions of the island across the Cienaga. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 77 mm., tail 76 mm., terminal 20 mm. regenerated; ventrals in 30 longitudinal and 8 transverse rows; fourth-toe subdigital scales 37 and 35 (total 72); femoral pores II and 10 (total 21); 27 scales in the fifteenth caudal verticil. Dorsum tan with head distinctly gray and set off from dorsal coloration; median and dorsolateral stripes paler tan and median line not espe- cially bold against ground color. Lateral fields much reduced because of en- 106 Annals of Carnegie Museum VoL. 41 croachment of brownish pigment along their edges, so that blaek pigment is restrieted to a short, sinuous line in the posterior half of the lateral field area. Lower sides gray, not blotched or vermiculate with darker. Tail dull grayish above, sides paler, and ventrolateral pale caudal stripe obscure. Throat pale blue and without any black pigment; belly and under side of tail pale blue. Limbs tan above and without darker reticulations or markings. A white transverse stripe on posterior face of thigh, surrounded by tannish gray above and below. VARIATION; The series of 91 A. a. marcida has the following counts; longitu- dinal ventrals 30-34 ( mode 32 ) ; rows of transverse ventrals 8 ( 6 specimens ) , 9 (1 specimen) or 10; fourth-toe scales 63-83 (mean 75.4); femoral pores 20-30 ( mean 24.8 ) ; fifteenth verticil 22-29 ( mean 25.0 ) . The largest male has a snout- vent length of 87 mm., the largest female 77 mm. The dorsal color of A. a. marcida varies from tan to brown. Adults are regularly the paler color and additionally have the head distinctly grayer than the back. The three dorsal lines are tan; the median stripe is always more obscure than the dorsolateral pair, and often becomes very faint or disappears on the posterior half of the trunk. The lateral fields are variable, but in most specimens there is more or less extensive brown pigment included along the margins of the fields, so that the more cen- tral black pigment is reduced in extent, often to as little as a sinuous or irregular line along the lateral field area. Juveniles have the dorsal lines more prominent than adults, but in subadults the lines have the faded appearance of fully adult specimens. The tails regularly lack the more prominent black or dark gray sides of the northern Isla de Pinos race ( although there may be a rather narrow lateral dark area along the sides of the tail). The throat and chest situation in A. a marcida is extremely peculiar. The specimens were divided into three categories : ( 1 ) black chest and throat; ( 2 ) black chest and black patch on throat; and ( 3 ) no black on chest or throat. Of 52 males, only six specimens (snout-vent lengths 65 mm. to 75 mm.) fall into categoiy 1. Fifteen males (snout-vent lengths 62 mm. to 87 mm. and thus including the largest males ) are included in category 2, and 31 males (snout-vent lengths 55 mm. to 85 mm.) lack any black throat or chest pigment, and have the throats and chests uni- color pale blue. In summary, slightly more than half the marcida males (31 of 52 specimens) lack any black pigment on either the chest or throat, but within the snout-vent-length range of these males are in- cluded both males with partially black throats and males with solid black throats and chests. The largest males have the chests black and the throats partially so. No females are included in category 1. Only two females (snout-vent lengths 53 mm. and 72 mm. ) are in category 2, and the balance of the 1970 Ameiva auberi: L The Cuban Subspecies 107 females (35 specimens), with snout- vent lengths from 48 mm. to 80 mm., lack any black throat pigment. In females, the vast majority of speci- mens lack black throats and chests. One of the two black- throated females (the larger) is from the Paso de Piedras, and might be inter- preted as showing some genetic influence of secta from the north (in which race only a very few females are comparable to males in chest and throat pigmentation). But the smaller female is from Puerto Frances, at the extreme western tip of the island, and thus far removed from any direct secta influence. The only interpretation I can offer of the entire chest and throat picture of marcida is that the southern Isla de Pinos population is in the process of losing the black pigmentation on the throat and chest, but that many adults of both sexes do not attain the pigmentless condition. COMPARISONS: Marcida is most pertinently compared with the more northern secta. Differences of throat pigmentation have just been reviewed. The majority of marcida can be separated from the majority of adult secta in that the former have pale blue rather than black throats. The dorsal coloration and pattern of the two races is surprisingly dif- ferent; marcida is in general faded and lacks the bold median and dorsolateral lines of secta as well as the prominent lateral fields with red markings. No other subspecies has a pale blue throat. Superficially there are resemblances between marcida and extraria: both are rather pale and have a poorly developed median line. The throat color in extraria is gray to diffuse dull orange. A. a. marcida is widely distributed on the southern portion of the Isla de Pinos, from Puerto Frances in the west to Punta del Este in the east. The specimens from Paso de Piedras are clearly marcida, and inter gradation between marcida and secta presumably occurs to the north of the Paso de Piedras, since only in this region is there an obvious possibility of contact between the northern and southern populations of A. auberi. The northern and southern portions of the Isla de Pinos are almost completely separated by the Cienaga de Lanier. On the southern part of the island, marcida was collected in beach scrub (Puerto Frances), in palm woods and broadleaf forest (Jacksonville and Punta del Este), and in rich, moist broadleaf forest (Paso de Piedras).

DIAGNOSIS: A Cuban subspecies of A. atiheri characterized by a combination of small size (males to 82 mm., females to 65 mm. snout-vent length), low number of fourth-toe subdigital scales and femoral pores, and very low number of scales in the fifteenth caudal verticil; dorsum pale sandy to tan, all dorsal lines pale yellowish tan, not especially contrasting with the dorsal ground color and fading posteriorly, lateral fields extensively black, with tan edging or at times included discrete tan dots, and throats white to pale blue ( except on Cayo Cantiles; see discussion ) , DISTRIBUTION: Known from five cays (Matias, Hicacos, Avalos, Cantiles, Largo) in the Archipielago de los Canarreos, east of Punta del Este, Isla de Pinos. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 66 mm., tail 51 mm., broken; ventrals in 33 longi- tudinal and 10 transverse rows; fourth-toe subdigital scales 37 and 36 (total 73); femoral pores 13 and 13 (total 26); 26 scales in the fifteenth caudal verticil. Dorsum pale sandy with median and dorsolateral lines pale yellowish tan and barely distinguishable from dorsal ground color, all three lines fading out on posterior half of trunk; head concolor with dorsum. Lateral fields black with a dorsal and ventral series of tan and irregular dots or scallops restricting the black pigment to a central irregularly-edged band; lateral fields bordered ventrally by a moderately bold pale tan lateral line; lower sides pale sandy, grading to blue ventrally, and without dark markings or vermiculations. Tail grayish tan dorsally, with a moderately well defined lateral black stripe which fades out distally; ven- trolateral caudal white stripe fairly conspicuous. Throat pale blue; venter pale blue laterally, white medially; under side of tail pale blue. Limbs concolor with back and without prominent darker vermiculations or markings. VARIATION: The series of 55 A. a. zugi has the following counts: longitudinal ventrals 30-34 ( modes 32 and 33 ) ; rows of transverse ventrals 8 ( 1 specimen ) — 10; fourth-toe scales 64-79 (mean 72.8); femoral pores 21-28 (mean 24.9); fifteenth verticil 22-28 (mean 24.9). The largest male is from Cayo Cantiles and has a snout-vent length of 82 mm.; the largest females are from Cayo Largo and Cayo Cantiles and have a snout-vent length of 65 mm. As might be expected, there is some variation between specimens of zugi from the various cays. Material from Cayo Cantiles is the most aberrant. Specimens from the more western islands (Matias, Hicacos, Avalos), which are much closer to the Isla de Pinos, are somewhat darker dorsally and are intermediate in this character between marcida and zugi, but are closer to the latter subspecies. Specimens from Cayo 1970 Ameiva auberi: I. The Cuban Subspecies 109 Largo are obviously the most extreme and have a distinctly bleached or faded appearance. In no adults from any cay are the dorsal lines con- spicuous, and these regularly fade out posteriorly to become lost in the dorsal ground color. The lateral fields are black centrally and have some tan-to-sandy markings along the upper and lower margins. In one specimen from Cayo Avalos, there is no black pigment on the lateral fields, these areas being concolor with the back. In general, the throats vary from white to very pale blue, and the venter is white centrally and pale blue laterally. The white transverse thigh stripe is usually present and surrounded by grayish tan. The tails are grayish tan to grayish dorsally in adults but are blue in juveniles. The series from Cayo Cantiles, recently collected by Sr. Garrido, is most interesting in that the series contains five individuals that have some black pigment on the throat and chest. Most extreme is a male (IB 1334, snout-vent length 70 mm. and thus not the largest male) that has a solid-black throat spot and some black on the mesoptychium and chest. A second male (IB 72, snout-vent length 80 mm., again not the largest male) has black on the posterior throat and mesoptychium and some black on the chest. The next two males (IB 1335, ASFS V11406, snout-vent lengths 81 mm. and 82 mm. ) have some black on the mesop- tychium and chest and scattered black scales on the throat. The final male (ASFS V11405, snout-vent length 68 mm.) has some black pig- ment on the mesoptychium only. No specimen of zugi from any other cay shows any indication of having black throat or chest pigment. Although the situation with the Cantiles lizards may well be comparable to that of extorris and extraria — i.e., assumption that the Cantiles Ameiva are a local derivative from a more widespread form (zugi) — I have have not named the Cantiles lizards as a distinct subspecies. I did not do so because (1) the population on Cantiles cannot be inter- preted as being black-throated since this feature occurs in only a small portion of the population, and (2) in contrast to extorris and extraria, the Cantiles lizards are '"surrounded” both to the east and west along the linear Archipielago de los Canarreos by more orthodox pale throated zugi. If one constructs a series (based upon the occurrence of black throats and chests ) of the Isla de Pinos-associated subspecies, the series is secta-marcida-zugi. This is almost surely a natural evolutionary se- quence as well. A. a. secta is predominantly black-throated, marcida has a lesser proportion of black-throated individuals, and in zugi, black- throatedness occurs only as a rarity on one cay within the chain. Just as marcida seems to be in the process of losing its capabilities for black- throatedness, so in zugi this potentiality has been lost almost completely 110 Annals of Carnegie Museum VoL. 41 except for occasional individuals, and apparently only on Cayo Cantiles. It seems best, under these circumstances, to consider the Cantiles lizards as slightly aberrant zugi. My opinions on this matter might well be changed if it could be demonstrated that Ameiva on the cays (Avalos, Matias, Hicacos) between Cantiles and Punta del Este also had some black-throated individuals, but the fairly extensive material (21 speci- mens) available from these cays does not show any such tendencies. comparisons: The only other Cuban subspecies comparable to zugi in dorsal coloration, pattern, and size is extraria from the northern cayeria of Las Villas Province. Extraria has the throat gray-to-dull orange, never white or pale blue, and has brown and inconspicuous lateral fields. Compared with marcida of the adjacent southern coast of the Isla de Pinos, zugi is distinctly paler and has the dorsal lines much fainter. The throat in marcida is pale blue or black. The means of fourth-toe scales in eoctraria (76.3) and zugi (72.8) are significantly distinct, whereas the mean of marcida (75.4) is closer to that of zugi, but still significantly different. REMARKS: The Archipielago de los Canarreos is a series of cays which extends roughly from Punta del Este eastward to Cayo Largo for a distance of about 145 kilometers. The keys have been generally dis- cussed by myself (Schwartz, 1959a: 117-118) in the description of the endemic subspecies Leiocephalus cubensis pamhasileus. No Ameiva were collected on Cayo Campos or Cayo del Rosario, both of which I visited with George Zug, for whom the cays' race is named. On Cayo Largo, A. a. zugi was secured on sun-baked mudflats adjacent to man- groves at the western end of the island, and on Cayo Matias and Cayo Avalos ground lizards were secured in the xerophytic vegetation that covers many of these cays. Cayo Cantiles, however, is rocky and covered with practically impenetrable jungle, and we secured only one Ameiva there along the very rocky and hazardous shoreline. Sutcliffe (1952:5-6) reported the occurrence of Ameiva (as Ameiva thoracica) on Cayo Largo and on Cayo Majas Chico, a small satellite of Cayo Largo. No specimens are available from the latter cay but I assume that they are assignable to A. a. zugi. A. a. zugi is obviously a derivative of A. a. marcida on the southern part of the Isla de Pinos. Presumably the former race is widespread on other islands of the Archipielago de los Canarreos, but the apparent absence of Ameiva on some cays we visited is paralleled by the absence of L. cid)ensis on some other cays. Leiocephalus was not collected on Matias, Avalos, Cantiles, Rosario, or Largo, whereas Ameiva was not 1970 Ameiva auberi: I. The Cuban Subspecies 111 collected on Campos or Rosario. Island size surely is not a factor in such vagaries of distribution, since both Campos and Rosario are much larger than M atlas and Avalos where Ameiva has been collected.

DIAGNOSIS: A Cuban subspecies of A. auberi characterized by a combination of moderate size (males to 87 mm., females to 75 mm. snout-vent length), mod- erate number of fourth-toe subdigital scales and femoral pores, high number of scales in the fifteenth caudal verticil; dorsum tan, often with the dorsal fields with some vague grayish marbling especially in their posterior halves, head and neck distinctly yellow-green ( almost chartreuse ) , dorsal lines yellowish tan, me- dian line fading posteriorly, lateral fields black with two or three longitudinal included series of reddish tan spots, and throats yellow-green. DISTRIBUTION: Known from six cays in the Laberinto de las Doce Leguas off the southern coast of Camagiiey Province, Cuba. description of holotype: An adult male with the following measurements and counts: snout-vent length 87 mm., tail 168 mm.; ventrals in 33 longitudinal and 10 transverse rows; fourth-toe subdigital scales 38 and 37 (total 75); femoral pores 12 and 13 (total 25); 28 scales in the fifteenth caudal verticil. Dorsum tan with median and dorsolateral lines yellowish tan, the median line visible only far anteriorly, but the dorsolateral lines fairly prominent above the lateral fields; head and neck distinctly yellowish green and in striking contrast to the dorsal color; dorsal fields with very vague grayish marbling, especially posteriorly. Lat- eral fields extensively black with about three longitudinal series of reddish tan spots which are fused vertically to give a series of more or less vertical reddish tan bars, although the spots often maintain their individual identities and are not fused; lateral fields bordered below by a pale lateral line. Lower sides blue-gray without prominent tigroid markings. Tail tan above, and with the pale ventro- lateral caudal stripe fairly prominent basally. Limbs tan above, marbled with gray vermiculations; pale transverse thigh stripe obscure and surrounded by grayish tan areas both above and below. Throat yellow-green; belly pale blue centrally, darker blue laterally; under side of tail pale blue to whitish. variation: The series of 29 A. a. galbiceps has the following counts: longi- 112 Annals of Carnegie Museum VoL. 41 I tudinal ventrals 31-35 (mode 33); rows of transverse ventrals 10-12 (1 specimen); fourth-toe scales 70-81 (mean 74.7); femoral pores 21-28 (mean 25.3); fifteenth verticil 25-30 (mean 27.8). The largest male is from the large cay 3 km. N.W. Cayo Cachiboca and has a snout-vent length of 87 mm. The largest female is from the same cay and has a snout-vent length of 75 mm. Throughout its range, A. a. galbiceps is fairly constant in coloration and pattern. The yellow-green head, neck, and throat are regular | features; no other subspecies of A. aiiheri has such a brightly marked | head or a yeUow-green throat. Many specimens (both adults and sub- I adults) have the dorsal fields with rather distinct grayish marbling, but ' these markings are very faint in the holotype and in some other speci- | mens. The lateral fields may have the series of reddish tan spots dis- | Crete or the spots may be fused, or partially fused, with one another as | in the holotype. The black area in the lateral fields is seldom extremely reduced or restricted, however, except in the specimen from Cayo | Caballones at the western end of the Doce Leguas. The dorsal lines are | yellowish tan and are fairly prominent at least anteriorly. The median j line fades posteriorly and is lost in the dorsal ground color. I comparisons: A. a. galbiceps in dorsal pattern resembles A. a. llanensis from the serpentine savannas of Camagiiey Province. Both have ! some grayish-to-brownish markings in the dorsal fields and are the only !' subspecies that have this feature. The yellow-green head and throat of ! galbiceps is a distinctive feature which occurs in no other subspecies; the throat in llanensis is pale orange. The yellow throat of procer far to the west on the Cuban mainland is similar to that of galbiceps, but the jj latter race has the throat pigmentation distinctly more green, is much j smaller, and has persistent dorsal lines in the adult. li REMARKS: The series of A. a. galbiceps was collected principally i: through the efforts of Gehrmann and Feick. The lizards were moderately H abundant on all the cays visited and were at once recognized as some- | thing quite distinctive from any populations that had been sampled on i the mainland. The absence of A. auberi material from much of the ' province of Camagiiey, especially the southern coast, makes comparison ■, of galbiceps with mainland populations difficult. It is interesting that no A. auberi have been collected by us or others throughout much of Camagiiey Province, despite apparently suitable habitats in very many areas. The dorsal field markings in galbiceps and llanensis suggest that they are related, but the ranges of the two are widely separated today. It is possible that llane7isis occurs much farther to the south than present records indicate, however. The scrub habitat of galbiceps is in contrast to the savanna habitat of llanensis. 1970 114 Annals of Carnegie Museum VoL. 41 TABLE 1 Subspecies of A. auberi Ranked by Snout- vent Length (in millimeters) of Largest Male Subspecies Largest Largest Male Female procer 136 115 atrothorax 126 93 garridoi no 70 gemmea 105 97 peradusta 105 76 denticola 96 78 granti 93 82 secta 93 77 auberi 92 88 hardtji 92 76 paulsoni 92 75 citra 92 72 llanensis 90 78 marcida 87 77 galbiceps 87 75 abducta 87 68 ziigi 82 65 pullata 81 81 mblesta 81 67 sabulicolor 80 66 cacuminis 80 60 extraria 79 68 ustulata 78 68 extorris 76 — TABLE 2 Subspecies of A. auberi Ranked According TO Mean Number of Femoral Pores Subspecies N Femoral Pores garridoi 23 27.6 (25-32) peradusta 28 27.2 (23-33) denticola 59 27.1 (23-31) atrothorax 65 26.8 (21-32) sabulicolor 47 26.7 (23-31) auberi 33 26.6 (23-31) pullata 24 26.3 (23-31) sublesta 12 26.3 (25-28) ustulata 85 26.2 (22-32) procer 62 26.0 (21-31) gemmea 15 25.9 (22-30) ( Continued next page ) 1970 Ameiva auberi; I.

McCoy Associate Curator, Section of Amphibians and Reptiles, Carnegie Museum, Pittsburgh, Pennsylvania Introduction Ameiva thoracica Cope was described in 1862 from a series of speci- mens collected on New Providence Island in the Bahamas by Dr. H. C. Wood, Jr. In Stejneger’s early revision of the Bahamian land-reptile |i fauna (in Shattuck, 1905),^ A. thoracica was listed from Eleuthera II Island, Andros Island, and Great Abaco Island, in addition to New Providence. Barbour and Noble (1915) correctly questioned the Great Abaco record, and Barbour ( 1916 ) reported thoracica from several localities in the Exuma Cays. Cochran (1934) recorded specimens col- lected by Bartsch, supposedly from the Ragged Islands and Crooked Island. By the time of Barbour’s ‘‘Third List of Antillean Reptiles and Amphibians’" (1937), Ameiva thoracica was firmly established as ''wide- spread in the northern and central portions of the Bahama Archipelago.” Despite the relatively long history of taxonomic recognition of Ameiva thoracica, infraspecific variation in this common Bahamian species has never been closely studied. Only the astute Tliomas Barbour, who probably saw more thoracica than any other herpetologist of his day, wrote “with much larger series Ameiva thoraeica may be shown to break up into several races” (Barbour and Shreve, 1935). In July, 1965, Neil D. Richmond of Carnegie Museum participated in the Fourth Expedition of the Bahamas Biological Survey, under the auspices of the American Museum of Natural History and the Office of Naval Research [Project No. 552(07)]. Among the specimens col- lected during this expedition were series of Ameiva auberi from widely scattered localities in the northern Bahamas, including the Berry Islands, Andros Island, the Exuma Cays, Long Island, the Ragged Islands, and Green Cay. With this fresh material available for study it became obvi- ous that Bahamian auberi exhibits a surprising range of variation in color and pattern. Preliminary observations on these specimens were extended to include examination of color and scale-count characters in auberi from throughout the Great Bahama Bank. The inter-population differentiation so immediately apparent in color patterns was substan- tiated and quantified by the data on scutellation and size. The variants occur as internally consistent geographic units, which are here given taxonomic recognition as subspecies. 1. Bibliography follows section III. 118 1970 Ameiva auberi: II. The Bahamian Subspecies 119 It is not surprising that the well-marked Bahamian subspecies of Ameiva auberi have previously escaped detection. The most important and obvious characters lie in fugitive elements of color and pattern which are inevitably destroyed by preservation. The quantitative treatment and statistical comparsion of scale counts are taxonomic tools only recently applied in studies of the macroteiid genera Ameiva and Cnemidophorus, and have not previously been used in treatments of A. auberi. Moreover, despite the accumulation of Bahamian Ameiva in many collections, ade- quate series of fresh and well-preserved specimens from many parts of the species' Bahamian range have been lacking. During this study I examined 480 specimens from 41 cays and islands representing nine major island groups on the Great Bahama Bank, including the Bimini Islands, the Berry Islands, Andros Island, New Providence Island, Eleuthera Island, Cat Island, the Exuma Cays, Long Island, and the Ragged Islands. I am grateful to the following curators and institutions (identified throughout by the abbreviations in parentheses ) for permission to examine species of Ameiva auberi in their care: Charles M. Bogert and Richard G. Zweifel, American Museum of Natural History (AMNH); Edmond V. Malnate, Academy of Natural Sciences, Philadelphia (ANSP); Albert Schwartz, Miami, Florida (ASFS); Walter Auffenberg, Florida State Museum (UF); and Doris M. Cochran and James A. Peters, United States National Museum (USNM). Specimens in the collections of Carnegie Museum are designated by the abbreviation CM. My special thanks are due Wayne King, George B. Rabb, Neil D. Rich- mond, and Albert Schwartz for permission to use unpublished field notes on Bahamian Ameiva, and to Richmond, Schwartz, and M. Graham Netting for helpful criticism of the manuscript. Gazetteer of Localities The confusing multiplicity of names available for the innumerable cays and islands of the Bahamas has caused some difficulty in interpre- ting locality data in museum catalogues and in the published literature. The following alphabetical gazetteer includes the names of all cays and islands of the Great Bahama Bank from which specimens of Ameiva auberi have been examined. The larger island groups are labeled on the accompanying map (Fig. 1), and reference to the map and this gazet- teer should permit general location of all islands mentioned in the systematic accounts. More detailed maps and charts, from which the place names here used were taken, are available in Kline ( 1964 ) and on U.S. Coast and Geodetic Survey chart 1002, “Straits of Florida.” 120 Annals of Carnegie Museum VoL. 41 ANDROS ISLAND (23° 43' - 25° 11' N., 77° 30' - 78° 28' W. ) — A very large island, approximately 110 miles long, north to south, by a maximum of 45 miles wide, lying in the western arm of the Great Bahama Bank.

Characters Studied In analyzing geographic variation in Bahamian populations of Ameiva auheri I have used a combination of characters, including scutellation, color pattern, and size differences. Four standard scale counts selected for analysis were: (1) number of dorsal granules counted in a line around midbody (GAB); (2) total number of femoral pores; (3) num- ber of scales in the fifteenth complete caudal verticil; (4) total number of subdigital scales on the fourth toes of both hind feet. Summaries of these data including mean values, ranges of variation, standard errors of the means, and sample sizes, in the eight Bahamian subspecies are presented in Table 2. In Tables 3 through 6 scutellation data for the eight subspecies are compared. In these latter tables a + ” symbol at the intersection of vertical and horizontal lines for two subspecies being compared denotes a statistically significant difference, based on non- overlap of the ranges described by two standard errors on either side of the mean counts for the character in the two forms. A ” indicates overlap of these ranges, and consequently the probable absence of a significant difference. The four characters of scutellation vary discor- dantly, and geographically adjacent races are frequently distinguished by significant differences in two or more characters. MIDBODY GRANULES ( GAB ) Northern populations from the Bimini Islands, Berry Islands, and Andros Island have the lowest GAB counts, but are not significantly different from each other. The populations of New Providence Island, Eleuthera Island, Gat Island, the Exuma Gays, and Long Island have I significantly higher GAB counts, and form a second overlapping group without internal differentiation. The Bagged Island population has GAB counts that overlap those of the northern populations. (Tables 2 and 3). FEMORAL PORES The populations of the Bimini Islands and Berry Islands have similar average femoral pore counts, at the upper limit of the range observed in Bahamian populations of A. auheri. The Andros Island sample has sig- nificantly lower femoral pore counts, but overlaps the New Providence and Eleuthera populations in this character. Ship Ghannel Gay and Gat 1970 Ameiva auberi: II. The Bahamian Subspecies 123 Island share counts significantly higher than the New Providence and Eleuthera group, and overlap the Bimini-Berry group. There is a sharp separation between the Ship Channel Cay population and more south- erly forms, which are united by much lower femoral pore counts. (Tables 2 and 4). FIFTEENTH CAUDAL VERTICIL SCALES The Bimini Islands and Berry Islands populations are similar in this character, and trenchantly differentiated from the Andros population which has a much lower mean count. The New Providence, Eleuthera, Cat Island, and Ship Channel Cay samples share overlapping counts at the upper limit for Bahamian populations. There is a sharp discontin- uity, partially bridged by the Long Island population, between the Ship Channel Cay population and the remainder of the Exuma Cay samples. Ragged Island lizards have even lower numbers of scales in the fifteenth caudal whorl, overlapping only the population of Andros Island in this character. (Tables 2 and 5). FOURTH TOE SUBDIGITALS Counts of subdigitals in lizards from the Bimini and Berry Islands populations are similar, and among the lowest found in the Bahamian races of A. auberi. The Andros Island population counts are only slightly, but significantly, higher than those of the northern populations. New Providence, Eleuthera, and Cat Island samples share even higher counts, significantly different from the Andros sample. The Ship Channel Cay population is differentiated from geographically adjacent popula- tions in this character, but overlaps the Andros and Ragged Island populations. Counts are slightly higher in the southern Exuma Cays and Long Island populations, and lower in the Ragged Islands lizards. (Tables 2 and 6). COLOR PATTERN The basic dorsal pattern of Bahamian Ameiva auberi, common to hatchlings and juveniles of all subspecies, consists of a series of five narrow, light, longitudinal stripes separated by darker fields three or four times wider than the stripes. Geographic variation in color pattern is expressed in the relative completeness of the stripes and their persistence through ontogeny, and in the color of the intervening fields. The middorsal stripe is continuous from the parietal scales to the base of the tail but never appears on the free part of the tail. At maxi- mum development the middorsal stripe passes forward between the orbits, where it is intensified and bordered by black marks, producing a brilliant black-yellow-black mark on the parietals. In some populations 124 Annals of Carnegie Museum VoL. 41 the middorsal stripe persists throughout life; in others it fades and the entire area between the dorsolateral stripes becomes unicolor. The paired dorsolateral stripes may origininate on the supraciliaries, above the ear openings, or farther back on the sides of the neck. They may persist throughout life or fade at adulthood, but are always more persistent than tlie middorsal stripe. Tlie lateral stripe is variable in ;; width, and sharply defines the lower edge of the dorsolateral field above, but may be either sharp-edged below or gradually blended with the " color of the lower sides. The dorsal fields, between the middorsal stripe and the dorsolateral jj stripes, are gray, brown, or reddish, with or without dark edges out- lining the adjacent shapes. The dorsolateral fields are usually black at |i hatching, although in some populations they are light-centered, or even jj spotted with lighter colors. In some populations old individuals grad- i ually resorb the black pigment, producing at first an emarginate field, then a punctate field, and eventually deshoying the black field entirely. The dorsolateral field frequently extends onto the tail as a black stripe. Tlie lateral field, below the lateral stripe, is usually diffuse and poorly defined, but in one population it is intensely black and relatively sharp- edged. Adult males of nearly all Bahamian populations exhibit extensive blackening of the throat, mesoptychium, chest, and undersides of the forelegs. The extent of the black ventral pigmentation is geographically variable, and often serves to differentiate adjacent subspecies. Sexual dimorphism in color pattern is further expressed in the potential for ontogenetic pattern changes. Females are usually much smaller than i males (Table 1), and retain juvenile elements of the pattern into adult- | hood. The ontogenetic pattern modifications produced by the loss of ! stripes and changes in the color of the fields not only start earlier in I males, but progress much further in the adult males. Females of all i populations tend to retain the juvenile pattern with relatively little j ontogenetic modification. i TABLE 1 Maximum Size in Bahamian Ameiva aiiheri Subspecies Total Examined Largest $ Largest $ richmondi 69 116.6 80.4 multilineata 54 119.7 71.3 kingi 32 99.4 72.2 thoracica 123 116.4 76’0 felis 46 97.0 61.7 focalis 22 109.0 83.0 ohsoleta 83 107.0 70.9 hilateralis 42 87.0 75.0 1970 Ameiva auberi: II. The Bahamian Subspecies 125 Finally, size has been used as a character differentiating some Baha- mian subspecies of Ameiva auberi. Absolute size differences are difficult to quantify and interpret, but in populations from which adequate sam- ples are available, differences in the potential size attained by adults are obvious. The maximum sizes, snout-vent length (SVL), observed in males and females of the various subspecies are listed in Table 1. Adult females are remarkably smaller than adult males in all Bahamian populations of Ameiva auberi. Systematic Review Ameiva auberi thoracica Cope Ameiva thoracica Cope, 1862, Proc. Acad. Nat. Sci.

REDESCBiPTiON OF HOLOTYPE: An adiilt male with the following measurements and counts: snout-vent length 114 mm., tail 267 mm. (tip missing); dorsal gran- ules at midbody (GAB) 112; femoral pores 14 and 14 (total 28); 32 scales in the fifteenth caudal certicil; fourth-toe siibdigital scales 40 and 42 (total 82). The dorsal ground color has faded to a uniform light gray, and the middorsal stripe is only faintly visible on the neck and anterior part of the back. The head is also a faded gray color dorsally. Dorsolateral light stripes extend from the temporal 126 Annals of Carnegie Museum VoL. 41 areas to the groin. The dorsolateral black fields are broad and ragged-edged, but solid black centrally and continuous from just behind the ears, well onto the posterior half of the tail. The areas immediately below these black fields are a slightly lighter gray, and definite light stripes extend from these light areas to the ears. Below the lateral light stripes and above the ventrals the gray ground color is stippled with black pigment. The dorsal surfaces of the fore- and hind- legs are uniform light gray. Ventrally the chinshields, throat, chest, under sides of the forelegs, and central ventrals to the pre-anal scales are black. Scales on the lateral, posterior, and anterior surfaces of the thighs are black with lighter centers, and the underside of the tail is dark The holotype is slightly soft, somewhat faded, and has the ventral body wall cut free as an anterior flap. Otherwise, the specimen is in good condition. Inexplicably Barbour and Loveridge ( 1929 ) wrote that the types of Ameiva thoracica Cope were not to be found, either in the Museum of Comparative Zoology or the Academy of Natural Sciences of Philadelphia. The series ANSP 9149-9180 unquestionably represents the syntypes of A. thoracica, and ANSP 9158, which most closely approximates the measurements and data given by Cope, is identified as the holotype. VARIATION: See tables. The type series from New Providence Island (ANSP 9149-9180) has the following counts: GAB 103-120 (110.6 zt .77); femoral pores 24-34 (27. 3 ±.41); fifteenth caudal verticil scales 29-37 (32. 2 ±.28); fourth- toe subdigitals 74-94 (82.3 ± .72). Ameiva auberi thoracica is a strongly lineate subspecies. In hatchlings and subadults the middorsal stripe is continuous to the frontoparietals, and somewhat intensified and black-edged on the head. The dorso- lateral stripes extend forward to the light-edged supraciliaries, and the lateral stripes are continuous to the ear openings. The middorsal stripe may be lost in the largest males, but persists in smaller males and all females. The dorsolateral and lateral stripes persist throughout life in all individuals. The dorsal fields, reddish brown in hatchlings, gradually fade to light brown or olive in older animals. The dorsolateral fields are intensely black and sharp-edged in all except the oldest males, in which they usually become emarginate or even reduced to a row of spots through loss of the black pigment. Tlie black dorsolateral fields have vague brick-red to dull tan edges in life. The lateral stripes, pale cream to gray in life, usually retain sharp lower edges throughout ontogeny. The ventral black coloration of adult males first appears at a snout- vent length of approximately 60 mm. (ASFS V10347) and gradually extends and intensifies until the throat, mesoptychium, chest, frequently the under sides of the forelegs, and most of the ventrals are solid glossy black. On the ventrals, however, black pigment is confined to the cen- tral four or six rows of scales, and the outer ventral scale rows are spotted and mottled with bluish pigment. The chinshields are almost always white, in striking contrast to the intense black of the throat granules. 1970 Ameiva auberi: II. The Bahamian Subspecies 127 In the largest males (AMNH 76281, 105 mm. SVL) the chinshields are also blackened along the inner edges. Hatchlings have reddish brown dorsal fields, a tan-to-yellowish mid- dorsal stripe, pale cream or yellow dorsolateral stripes, and a grayish green tail. The series from Eleuthera Island has the folowing scale counts: GAB 99-129 (109.8 =b .16); femoral pores 23-30 (26.6 ± .31); fifteenth caudal verticil scales 28-34 ( 31.2 it .24); fourth-toe subdigitals 74-93 (81.2 zb .66). Despite the significant difference in mean number of fifteenth caudal verticil scales, and some subtle differences in color pattern, the Eleuthera Island sample (which consists mostly of hatchlings and juve- niles) is referred to thoracica. Elements of the color pattern shared by Eleuthera and New Providence populations are the distinct and anter- iorly extensive stripes, the reddish-brown dorsal and black dorsolateral fields, and the striped interparietal and supraciliaries. In contrast to New Providence lizards, Eleuthera individuals show early loss of the middorsal stripe (ASFS V6824, male, 76 mm. SVL), less extensive black ventral coloration in adult males, extreme reduction and eventual loss of the black pigment in the dorsolateral fields (USNM 31992), and blue rather than green tails as hatchlings. Nevertheless, in view of the divergence of adjacent populations on Andros Island, Cat Island, and Ship Channel Cay, internal variation of thoracica seems relatively insignificant. Evidence from populations inhabiting the islets and cays connecting New Providence and Eleuthera, which could illuminate the relation- ships of the end populations, is inconclusive. Four specimens from Rose Island (AMNH 76255-76258) have characters common to both popula- tions, although the adult male ( 92 mm. SVL ) has reduced throat color suggestive of Eleuthera males. A single specimen from Little San Salvador Island (MCZ 39645) is referred to thoracica, rather than to the subspecies of nearby Cat Island, on the basis of the unmarked solid black dorsolateral fields and a mid- dorsal stripe continuous onto the parietals. coMPARisiONs: Although Ameiva auberi thoracica includes a relatively large range of variation, the subspecies has adequate internal agreement when compared with adjacent races. The population of Andros Island has significantly fewer dorsal granules, fifteenth caudal verticil scales, and fourth-toe subdigital scales. These populations share elements of the color pattern, but the rich bronze-red dorsal fields of Andros Island lizards is not matched by thoracica. To the east there are similarly 128 Annals of Carnegie Museum VoL. 41 trenchant differences between thoracica and the Cat Island subspecies. Cat Island lizards have higher GAB counts, more femoral pores and are probably significantly smaller as adults. In addition, the dorsolateral fields of thoracica are solid black or emarginate rather than internally spotted as in the Cat Island population. Some of the differences between New Providence thoracica and the Cat Island population may be par- tially bridged by adequate samples of adult lizards from Eleuthera Island. Ameiva auberi thoracica finds its closest relative in the population of i: Ship Channel Cay, which is almost surrounded on the north by the range of thoracica. There are significant differences here in femoral pores and fourth-toe subdigital scales, but size and other characters of scala- tion are similar. Although the color patterns are grossly alike there are substantial differences in the extent of the ventral coloration in males, in the color of the snout, and in the tendency to lose dorsal striping. : Ameiva auberi felis, new subspecies ■ holotype: cm 20440, an adult male, from The Bight, Cat Island, Bahama n Islands, taken on June 14, 1941, by George R.

DIAGNOSIS: A Bahamian subspecies of Ameiva auberi characterized by a com- bination of moderate size (males to 97 mm., females to 62 mm. SVL), high num- ber of dorsal granules at midbody, high number of femoral pores, moderate : number of scales in the fifteenth caudal verticil, and high number of fourth-toe ' subdigital scales; dorsal stripes becoming obsolete with age, dorsal fields olive- gray, dorso-lateral fields black spotted with lighter color; throat, mesoptychium, and anterior few rows of ventrals black in adult males. distribution: Cat Island, Bahama Islands. DESCRIPTION OF THE HOLOTYPE: An adult male with the following measure- ments and counts: snout-vent length 72.3 mm., tail incomplete; dorsal granules at midbody 109; femoral pores 13 and 13 (total 26); 30 scales in the fifteenth ; caudal verticil; fourth-toe subdigital scales 39 and 40 (total 79). Dorsal ground color dark olive, middorsal and dorsolateral stripes completely absent. Dorsolateral ■ black fields continuous from above forelegs to groin, and punctuate with num- erous, almost confluent light spots, producing a distinctly reticulate appearance. Lateral light stripe medium gray, sharp-edged above and below, and bordered |i below by a dark gray field shading into the dark ventrals. Dorsal surfaces of limbs , 1970 Ameiva AUBERi: II. The Bahamian Subspecies 129 olive. Central part of throat, mesoptychium, and anterior three rows of ventrals black, the black extending to the under surfaces of the forelegs as black stippling on dark gray. Lateralmost few rows of ventrals light-spotted, remainder of ven- tral surface dark gray, probably as a result of overexposure to strong formalin. The holotype appears to be generally darkened by improper preservation. VARIATION: See tables. The presence of reddish spots in the dark- brown-to-black dorsolateral fields of felis is unique among Bahamian races of Ameiva auberi. These spots are visible in hatchlings, and may grow and coalesce with adjacent spots and with the border of the dorso- lateral field to form a ragged or even reticulate field in older individuals. The majority of animals exhibit distinctly spotted dorsolateral fields. The middorsal stripe is tan-orange to tan, continuous onto the inter- parietal in post-hatchlings (ASFS V2117, 42 mm. SVL), but completely obliterated by the brown-to-medium-brown dorsal fields in the largest males. The dorsolateral stripes are also tan-orange in life and more persistent than the middorsal stripe. In even the smallest individuals examined the dorsolateral stripes end above the foreleg insertions. The lateral stripes are wide and buffy in life, and bordered below by lateral fields of purplish blue. The lateral fields may be irregularly spotted, giving a checkered appearance to the lower sides. The ventral color in life is pinkish blue or slightly purplish marked with black in adult males. The black ventral markings first appear at approximately 55 mm. SVL as a black smudge in the center of the throat, a black mesoptychium, and blackening of the anterior few rows of chest scales. Fully developed, the black covers most of the throat (but usually not the chinshields ) , the mesoptychium and under sides of the forelegs, and the anterior third of the ventral scales. The tail is bright blue to blue-green in life, and several hatchlings retain a bright cerulean, but distinctly striped, tail in pre- servative. COMPARISONS. Ameiva auberi felis stands alone among the Bahamian races of auberi in the presence of light-spotting in the dorsolateral fields. From the adjacent population of the Exuma Cays felis is strongly divergent in all characters of scalation, and probably has closest affinity with the Eleuthera Island population of thoracica. Eleuthera Island thoracica and felis have a tendency toward ontogenetic loss of the mid- dorsal stripe, similar GAB counts, fifteenth caudal verticil scale counts, and fourth-toe subdigital scale counts. They are distinguished by a significant difference in femoral-pore counts, and by the completely different color of the dorsolateral fields, which early in life fade into zones of black spots in Eleuthera Island thoracica. 130 Annals of Carnegie Museum VoL. 41 Ameiva auberi kingi, new subspecies holotype: cm 40915, an adult male, from Gibson Cay, in the mouth of South Bight, Andros Island, Bahama Islands, taken on July 4, 1965, by Neil D. Richmond. PARATYPEs: CM 40916-40920, same data as holotype. ASSOCIATED SPECIMENS: All from Andros Island (localities arranged from north to south) as follows: UF 5982, 17923-17924, approx. 9 mi. at 240° from Stafford Creek Settlement; ASFS 10287-10293, Fresh Creek; UF 17927-17930, Andros Town; UF 17920-17921, east tip of Reid’s Cay, North Bight; MCZ 42008, Man- grove Cay; MCZ 42003, south side of South Bight; UF 17931-17933, 2 mi. at 55° from mouth of Deep Creek; MCZ 42006-42007, Cistern Creek. DIAGNOSIS: A Bahamian subspecies of Ameiva auberi characterized by a com- bination of moderate size (males to 99 mm., females to 72 mm. SVL), low number of dorsal granules at midbody, moderate numbers of femoral pores and fourth-toe subdigital scales, and very low number of scales in the fifteenth caudal verticil; middorsal stripe persistent in adults, dorsal fields reddish brown, dorsolateral fields black; chinshields, throat, mesoptychium, and anterior fourth of ventrals black in adult males. DISTRIBUTION: Audros Island, Bahama Islands. DESCRIPTION OF HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 99.4 mm., tail 258 mm. (complete); dorsal gran- ules at midbody 97; femoral pores 13 and 13 (total 26); 27 scales in the fifteenth caudal verticil; fourth-toe subdigital scales 36 and 37 (total 73). Dorsal fields a rich, reddish brown, shading to medium brown on top of the head and tail. Middorsal stripe gray, extending from the frontoparietal almost to the middle of the back. Dorsolateral light stripes intense, extending from the temporal regions to near the groin. Dorsolateral black fields vivid and sharp-edged, bearing narrow stripes of lighter color adjacent to the bordering light stripes. Lateral light stripes broad, subtended by lines of irregular black spots above the ends of the ventrals. Chinshields, throat, chest, under sides of forelegs, and approximately a quarter of the anterior ventrals black. Posterior ventrals bluish laterally shading to white at mid-venter; pre-anal scales, under surfaces of thighs, and lower side of tail very light gray with wliite mottling. Tail brown above, with black and white stripes, light gray below. Dorsal surfaces of limbs gray-brown, stippled with black. VARIATION: See tables. The type series from Gibson Cay (CM 40915-40920) has the following counts: GAB 88-103 (average 96.8); femoral pores 22-26 (24.2); fifteenth caudal verticil scales 27-31 (28.3); fourth-toe subdigital scales 73-77 (74.7). Ameiva auberi kingi is characterized by reddish brown, almost bronze, dorsal fields in combination with solid black dorsolateral fields. The middorsal stripe is buff to yellowish in life, and continuous anteriorly beyond the parietal scales where it is bordered by black marks on each side, forming a distinctive black-white-black mark on the head of pre- served specimens. The dorsolateral stripes are continuous from the canthals, over the supraciliaries (also yellow), to the base of the tail. The stripes become intensely yellow near the groin. The black dorso- 1970 Ameiva auberi: II. The Bahamian Subspecies 131 lateral fields are edged with brown to brick-red stripes in life, and the dorsal fields have dark edges in hatchlings. The venter is dirty white to gray, and adult males have intense black ventral markings which cover the chinshields, throat, mesoptychium, under sides of the forelegs, and a few anterior rows of ventrals. The greatest extent of ventral blackening is exhibited by a male from Gibson Cay ( CM 40918, 87 mm. SVL ) that has the anterior four ventral rows, as well as the centers of the next three rows, entirely blackened. The series of specimens from Fresh Creek (ASFS 10287-10293) shows several distinct differences in color pattern from the Gibson Cay sample. In the Fresh Creek series the vivid white middorsal stripe is broadly edged with black, from the parietals to about the midpoint of the back. In the smaller specimens {ca. 50-60 mm. SVL) the dorsal fields are light-centered and black-edged. The dorsolateral fields, however, are solid black, without evidence of light centers. These seven specimens average 104.9 dorsal granules at midbody (95-115); 27.3 femoral pores (25-32); 28.4 scales in the fifteenth caudal verticil (26-30); and 80.4 fourth-toe subdigital scales ( 74-89 ) . The huge land mass of Andros Island is largely unexplored herpeto- logically. Available samples of Ameiva auberi from Andros are inade- quate for analysis of intra-island variation, but there are suggestions that representative series from all parts of the island may reveal the presence of more than one recognizable race. COMPARISONS: Ameiva auberi kingi occupies a position of intermediacy in scale counts between thoracica and the populations of the Berry and Bimini Islands to the north. In GAB counts, kingi, with the Berry and Bimini Island populations, forms a compact group distinct from all other Bahamian races of Ameiva auberi. Femoral pore counts, on the other hand, align kingi closely with the thoracica-felis group. In fifteenth caudal verticil and fourth-toe subdigital scale counts kingi is significantly different from the geographically adjacent populations, and in both these characters, overlaps the Ragged Islands population far to the south. The color pattern of kingi shows a strong resemblance to thoracica in the development of the stripes anteriorly on the parietals, frontals, and supraciliaries. The general tendency for intensification of the middorsal stripe on the head reaches a maximum in the Fresh Creek population of kingi. The combination of solid black dorsolateral fields and reddish brown dorsal fields distinguishes kingi not only from thoracica, but from all other Bahamian populations of Ameiva auberi as well. Further points of difference between kingi and geographically adjacent populations are 132 Annals of Carnegie Museum VoL. 41 found in the development of the black ventral coloration in adult males. The extent of blackening of the ventral scales is much less in kingi than in thoracica, but kingi, unlike thoracica, has black chinshields. The com- bination of divergent scale counts with the reddish dorsal and black dorsolateral fields makes kingi one of the most distinctive Bahamian races of Ameiva auberi.

DIAGNOSIS: A Bahamian subspecies of Ameiva auberi characterized by a com- bination of very large size (males to 120 mm., females to 71 mm. SVL), low number of dorsal granules at midbody, fairly high number of femoral pores, moderate number of scales in the fifteenth caudal verticil, and very low number of fourth-toe subdigital scales; all dorsal stripes persistent and continuous onto the head, lateral stripes sharp-edged and distinct, dorsal and dorsolateral fields light reddish brown with dark edges; chinshields, throat, mesoptychium, and most of the central ventrals black in adult males. distribution: The Berry Island group, Bahama Islands. Definitely known from Bond’s Cay, Chub Cay, Cistern Cay, Devil’s Cay, Frazer’s Hog Cay, and Little Harbour Cay. DESCRIPTION OF THE HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 97.6 mm., tail 237 mm. (complete); dorsal granules at midbody (GAB) 105; femoral pores 15 and 14 (total 29); 31 scales in the fifteenth caudal verticil; fourth-toe subdigital scales 36 and 40 (total 76). Dorsal ground color reddish brown, top of head gray. Middorsal stripe distinct and sharp- edged from the interparietal almost to the sacrum, edged with dark brown. Dorsal fields light-centered, the dark brown edges bordering the adjacent stripes. Dor- solateral stripes bright gray-white, continuous from the supraciliaries onto the tail, ' and broadly and sharply edged on both upper and lower sides with dark brown. Dorsolateral field light red-brown centrally, dark brown to black at the edges. Lateral stripe sharp-edged above and below, distinctly lighter than the ventro- lateral field, continuous to the ear. Sides below the lateral stripes gray, shading into the black ventrals. Chinshields, throat, mesoptychium, under sides of forelegs, chest, and almost all ventrals (both central and lateral) black. Lateralmost few rows of ventrals spotted with blue. Under sides of thighs and pre-anal scales light gray mottled with dark gray, and spotted with blue. Under side of tail grayish white. Dorsal surfaces of limbs brown, mottled with dark gray or black. VARIATION: See tables. The type series from Bond’s Cay (CM 41195-41199) has the following counts: GAB 97-107 (average 104.2); femoral pores 27-31 (29.0); fifteenth caudal verticil scales 28-31 (28.9); fourth-toe subdigital scales 72-77 (75.2). 1970 Ameiva auberi: II. The Bahamian Subspecies 133 The most distinctive feature of Ameiva auberi multilineata, as the name implies, is the many-lined appearance of adults. This effect is produced in part by the persistence of the dorsal light stripes, and in part by the dark borders located in the edges of the light dorsal fields. In life the dorsal and dorsolateral fields are brick-red to red-brown in the centers, and dark brown at the edges. Even in hatchlings (CM 41160, 37.7 mm. SVL), the light centers of the dorsolateral fields are apparent. The middorsal stripe in multilineata is unusually vivid, about twice the width of the dorsolateral stripes, and distinctly grayish rather than yellow. The lateral stripe is pale gray, and the lower sides are slightly darker gray. Black ventral coloration appears in males at about 65 mm. SVL, and eventually involves the chinshields, throat, mesoptychium, chest, under sides of the forelegs, and part of the ventrals. In the very largest males more than half of the ventrals are blackened, but the outermost rows of ventrals remain dark gray with bluish spots and mottling. The short series of specimens from Little Harbour Cay (AMNH 76294-76298) shows a tendency toward development of light-spotting in the dorsolateral fields, and to some extent in the dorsal fields. The spots give a dilute or faded appearance to the dorsal pattern of the adult female, and in a lesser degree to that of the adult males. The stripes are persistent and black-edged, however, and other details of color pattern are normal for the subspecies. A series of magnificent specimens from Devil’s Cay (AMNH 76299- 76303 + 3 untagged) includes three males between 110 and 120 mm. SVL — the largest Bahamian Ameiva known. In these gigantic specimens the dorsal and dorsolateral fields are faded to a uniform light brown, and the middorsal stipe is visible only on the anterior half of the body. The most striking aspect of the pattern of these animals is the vivid yellow, black-edged dorsolateral stripes diagnostic of multilineata. The black ventral coloration involves slightly more than half of the ventrals in these largest males. COMPARISONS: Ameiva auberi multilineata is the largest Bahamian race, approached in size only by the Bimini Island subspecies and by thoracica. The Bimini Island population and multilineata share scale- count characters that differentiate them from all other Bahamian races of Ameiva auberi. In GAB counts, multilineata and the Bimini popula- tion overlap only with kingi; their fifteenth caudal verticil scale counts distinguish them from kingi, thoracica, and felis but not from other races; and in fourth-toe subdigital counts they differ significantly from all other Bahamian subspecies of auberi. Femoral pore counts separate multilineata from all races except felis. 134 Annals of Carnegie Museum VoL. 41 The northernmost two subspecies of Ameiva auberi, multilineata and [ the Bimini Island subspecies, share a significant number of features of ' color pattern and scutellation and are strongly differentiated from all r other Bahamian races. The subtle characters that serve to distinguish |i these two populations from each other are outlined in the following discussion of the Bimini Island subspecies. The reddish brown dorsal | fields of these northern populations separate them from all Bahamian races except kingi, and the light-centered, dark-edged dorsolateral fields j| are found only in this northern group. The persistence of the dorsal i striping is unmatched in any other subspecies, and the reduction of ven- tral blackening in adult males distinguishes the northern pair of races from adjacent forms. Together, these two populations form a unit sharply divergent from all other Bahamian races of Ameiva auberi, not only in color pattern but also in size and scutellation.

The Bahamian Subspecies 135 DESCRIPTION OF THE HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 91.1 mm., tail 178 mm. (regenerated); dorsal granules at midbody (GAB) 108; femoral pores 15 and 15 (total 30); 30 scales in the fifteenth caudal verticil; fourth-toe subdigital scales 37 and 37 (total 74). Dorsal ground color medium reddish brown, head slightly lighter and more yellowish. Middorsal stripe light gray, continuous from interparietal almost to sacrum, not noticeably dark-edged. Dorsolateral light stripes from temporal areas to groin, light gray and distinct, and edged on the anterior half of the body with black flecking both above and below. Dorsolateral fields reddish brown, lighter than the dorsal fields, with concentrations of black stippling along the upper and lower edges anteriorly. Lateral stripe light gray, dark-edged above and sharp but fading into a dark gray area below and above the ventrals. Dorsal surfaces of limbs medium brown. Inner half of chinshields, throat, chest, and approximately one-third of anterior central ventrals black. Posterior central ventrals blue-gray, spotted with white; lateral ventrals dark gray, spotted with blue. Under sides of thighs gray- blue, spotted with white and pre-anal seales white. Tail indistinctly striped, brown above and gray below. VARIATION: See tables. The type series from North Bimini Island has the fol- lowing counts: GAB 91-108 (99.8 ± .89); femoral pores 28-34 (30.0 ±.36); fifteenth caudal verticil scales 28-31 (29. 6 ±.22); fourth-toe subdigitals 68-75 (71.7 ± .40). Ameiva auberi richmondi is another strongly lineate race from the northwestern corner of the Great Bahama Bank. Hatchlings of riehmondi have vivid cream dorsal and dorsolateral stripes, usually somewhat expanded but never black-edged on the head. The stripes remain bril- liant cream to yellow in subadults and adult females but are consider- ably diluted and reduced to paler yellow or yellow-gray in adult males. In adults the dorsolateral stripes are continuous only onto the neck, and the lateral stripes to the forelegs. The dorsal and dorsolateral fields are black or dark brown at the edges in hatchlings, the former with broad red-brown central fields, the latter with very narrow lighter centers. As the lizards grow, the light central zones of the dark fields enlarge and eventually obliterate the dark edges. The dorsal field becomes completely light long before the dorsolateral field is unicolor. The lateral stripe is cream to gray, sharp-edged above, but blending gradually into the darker color below. In an adult male paratype from North Bimini Island (ASFS V11603, 98 mm. SVL), the middorsal stripe is light gray and visible from the posterior edge of the parietal scales almost to the sacrum. The light gray dorsolateral stripes originate in the temporal areas and extend nearly to the groin. The dorsal and dorsolateral fields are almost exactly the same shade of light brown, and their black edges persist only as scattered melanophores along the edges of the dorsolateral stripes. The lateral stripes, and the sides below, are uniform light gray. 136 Annals of Carnegie Museum VoL. 41 The tail of hatchlings is bright blue; that of adults is gray above, and white marked with bluish mottling below, and is not black-striped along I the side. I Suffusion of the gular area with black pigment begins at an early age 1 in richmondi, and all males over 65 mm. SVL have extensively black- ened throats and mesoptychia. The usual maximum extent of the black j includes the throat, mesoptychium, chest, under sides of the forelegs, and : approximately one-third to one-half of the anterior ventrals. The lateral j ventrals are blue-spotted, and the pre-anal and thigh scales are dirty | white. In a common variant type, represented in series from East Bimini Island, South Bimini Island, and Easter Cay, the black of the ventral ji scales is restricted to the first two or three transverse rows. Tlie remain- ;i der of the ventrals is white, mottled with light gray. | In virtually all aspects of color and scutellation, the populations of the i various islands and cays of the Bimini Islands form a close-knit and ■ relatively invariable group. ' COMPARISONS: The close similarity of Ameiva auberi richmondi with i multilineata and their trenchant differences from the other Bahamian races of Ameiva auberi have been mentioned. It remains only to point out the characters that differentiate these two subspecies of the north- western arm of the Great Bahama Bank. These races are almost identical in all counts except femoral pore scales, which are significantly more numerous in richmondi. Here, admittedly, the difference is small, but it is based on large samples from each island group, and the standard j. errors of the mean values are reassuringly small. Size is another distin- j guishing characteristics of these races. Male richmondi attain a maximum snout- vent length of 117 mm., but they do not compare in bulk to the 120 mm. males of midtilineata. There are several subtle, but constant characters of color pattern that ‘ distinguish richmondi from multilineata. Paramount among these is the : early loss, in richmondi, of the black edges of the dorsolateral fields, producing uniform-colored rather than the dark-edged fields of multi- I lineata. In richmondi the dorsal stripes of adults are less extensive anteriorly, and the lateral stripe less well defined, in comparison with multilineata. Finally, the ventral black pattern of male richmondi rarely j: includes the chinshields, which are always dark in multilineata. In sum, the subspecies richmondi and 7nultilineata are remarkably j similar and obviously share a common ancestry. Nevertheless, there I are constant characters of both color and scutellation that can be used to differentiate them. Furthermore, their relative isolation from one another , 1970 Ameiva auberi: II. The Bahamian Subspecies 137 at opposite ends of the northwestern arm of the Great Bahama Bank leads me to regard their subtle but consistent differences as adequate evidence of subspecific divergence. Ameiva auberi focalis, new subspecies holotype: cm 41147, an adult male, from Ship Channel Cay, Exuma Cays, Bahama Islands, taken on July 23, 1965, by Neil D. Richmond. PARATYPEs: All from Ship Channel Cay, as follows: CM 41139-41146, same data as holotype; ASFS V10718-V10730, taken on July 6, 1966, by J. B. Brown, A. Schwartz, and R. Thomas. diagnosis: A Bahamian subspecies of Ameiva auberi characterized by a combi- nation of fairly large size (males to 107 mm., females to 83 mm. SVL), very high number of dorsal granules at midbody, moderate number of femoral pores and fifteenth caudal verticil scales, and low number of fourth-toe subdigital scales; middorsal stripe lost in adults, dorsal fields olive, dorsolateral fields black, chin- shields and throat blue, black ventral markings reduced to a bar in the center of the mesoptychium and another on the anterior two or three rows of ventrals, snout pink. DISTRIBUTION: Known only from the type locality. Ship Channel Cay, but pos- sibly occurs on several of the northernmost Exuma Cays, Bahama Islands. DESCRIPTION OF THE HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 110.3 mm., tail ea. 239 mm (complete); dorsal granules at midbody 112; femoral pores 14 and 14 (total 28); 30 scales in the fifteenth caudal verticil; fourth-toe subdigital scales 37 (one toe missing). Dorsal ground color, top of head and dorsal sides of limbs olive gray. Middorsal stripe faintly indicated as a lighter gray area. Dorsolateral light stripes also faint and only feebly lighter than the ground color. Dorsolateral dark fields slightly emargi- nate, but vivid black and continuous from the foreleg insertions to the groins. Below the dorsolateral black fields are slightly lighter gray areas, blending into the gray-blue ventral color. None of the stripes extends onto the neck, which is entirely unlined, shading gradually from the ventral blue-gray to the dorsal olive gray. Mental scale, rostral scale, and anterior upper and lower labials lighter than other head scales. Entire ventral surface from chinshields to pre-anals light gray-blue, with a small patch of black scales on the mesoptychium and black stippling on the anterior two transverse rows of ventral scales. Central posterior ventrals, femoral-pore-scale rows, and under side of tail white with blue-gray smudging. Tail weakly but distinctly striped laterally, olive-gray dorsally. VARIATION (See tables): Ameiva auberi focalis is unique among the Bahamian races of the species in the extreme reduction of the black ventral coloration of adult males. The maximum development consists of a black bar across the mesoptychium, a second bar on the anterior two and one-half rows of ventral scales, and a speckling of black throat granules. The under sides of the forelegs, chinshields, and throat are never solid black. The entire ventral surface is usually gray-blue in males, white in females. Adult males occasionally lack any trace of the usual black ventral pigmentation (CM 41146). 138 Annals of Carnegie Museum VoL. 41 The middorsal stripe is pale lemon-yellow in life, continuous from the frontal scale to the sacrum in the smallest specimens examined (ASFS V10729-V10730, ca. 65 mm. SVL), but is not black-edged on the head. The middorsal stiipe is persistent in adult females, but may be com- pletely lost in large males (CM 41140, 107 mm. SVL). The dorsal fields are olivaceous in life, and the dorsolateral stripes are tan to yellowish, vaguely continuous to the supraciliaries in small individuals. In old adults the dorsolateral stripes are conspicuously brighter than the mid- dorsal stripe. The intense black dorsolateral fields retain their consistency through- out life, or may be slightly invaded by their narrow brick-red edging. The lateral stripes and lateral fields are only poorly differentiated, greenish in life, and blend gradually with the blue-gray ventral color. The tail is gray above in adults, lighter than the olive dorsal fields, black-striped laterally, and gray-blue below the stripe, shading to white midventrally. comparisons: Although immediately distinguishable by the reduction of black ventral markings in adult males, Ameiva auberi focalis shares a combination of characters of the geographically adjacent subspecies. In scale counts focalis is not significantly different from thoracica in gran- ules around midbody and fifteenth caudal verticil scales but has a sig- nificantly higher number of femoral pores and a significantly lower number of fourth-toe subdigital scales. From the populations farther south in the Exuma Cays chain, focalis is significantly different in both fifteenth caudal verticil scales and fourth-toe subdigital scales, differences which are, in both cases, partially bridged by the Long Island popula- tion. There is broad overlap with the southern populations in number of granules at midbody, but the number of femoral pores is significantly different. Tlius focalis overlaps the range of variation of the adjacent population on the north in two characters and of the population on the south in three characters. Ameiva auberi foealis is distinguished from the adjacent subspecies on the north by two characters, and from the popu- lation on the south by one character. Elements of the color pattern of foealis may also be traced to the neighboring populations. The pink nose and tendency for early loss of the middorsal stripe are shared with the populations in the Exuma Cays. Retention of the solid black dorsolateral fields throughout life, lack of a well-defined, conspicuously lighter lateral stripe, and olive rather than gray dorsal fields are characteristic of Ameiva auberi thoraeiea. The cays immediately to the south of Ship Channel Cay along the 1970 Ameiva auberi: II. The Bahamian Subspecies 139 chain of the Exuma Cays have been poorly explored herpetologically. Scanty evidence suggests that there may be an actual hiatus in the range of Ameiva auberi between Ship Channel Cay and the northern- most island inhabited by the Exuma Cays subspecies (A. Schwartz, in lift. ) . The details of the distribution of Ameiva auberi in the northern Exuma Cays are in need of investigation to clarify the exact range of focalis and the relationship of focalis to the Exuma Cays subspecies.

DISTRIBUTION: The southern Exuma Cays and Long Island, Bahama Islands. Definitely known from Warderick Wells Cay, Bell Island, Sampson Cay, Bitter Guana Cay, Great Guana Cay, Cave Cay, Great Exuma Island, Elizabeth Cay, and Little Exuma Island, all in the Exuma Cays group, and from several localities on Long Island. The specimens reported from Crooked Island (Cochran, 1934) belong with this subspecies (see below). DESCRIPTION OF THE HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 86.6 mm., tail 225 mm. (complete); dorsal granules at midbody (GAB) 103; femoral pores 13 and 13 (total 26); 32 scales in the fifteenth caudal verticil; fourth-toe subdigital scales 40 and 40 (total 80). Dorsal ground color and top of head medium gray-brown, middorsal stripe faded. Dorso- lateral light stripes narrow but bright, extending from the forelegs to the tail. Dorsolaterial fields intensely black, slightly emarginate. Lateral light stripes dirty gray-white, sharp-edged both above and below. Ventrolateral fields black with a series of large, discrete, light spots. Dorsal surfaces of limbs dark brown. Chinshields, throat, under side of forearms, chest, and two-thirds of central ventrals black. Posterior third of central ventrals off-white smudged with gray. Lateral 140 Annals of Carnegie Museum VoL. 41 I ventrals tessellated (light blue on black). Pre-anal scales, under sides of thighs, I and under sides of tail dirty white. Dorsal surface of distinctly striped tail gray- brown. Middorsal field brown to tan, dorsolateral stripes buff, lateral stripes pale gray to buff, and tip of snout orange in life ( R. Thomas, field notes). VARIATION ( See tables ) : The type series from Long Island has the following i' counts: GAB 96-117 (107.07 ± 1.1) femoral pores 22-30 (25.7 ± .37); fifteenth I caudal-verticil scales 27-33 (30.5 zt .30); fourth-toe subdigital scales 72-90 , (83.6 ±1.1). ! The most striking and immediately obvious characteristic found in ' all populations of Ameiva auberi ohsoleta is the early loss of the mid- dorsal stripe and eventual fading of all lineate parts of the dorsal pattern, i In the Long Island series the middorsal stripe is only faintly visible in the smallest specimen (ASFS V8598, 40 mm, SVL) and is completely ' obliterated in all larger individuals. The resulting broad middorsal zone ! between the dorsolateral stripes is light brown to gray. The faint buff ; dorsolateral stripes are continuous from the forelegs to the sacrum even ! in large specimens. The intense black dorsolateral fields are emarginate ; in very old specimens, but retain their integrity in the type series. The i lateral stripe is light gray, and the dark gray field below it is light- | spotted. The black ventral coloration of males appears at an early age. One 68-mm. male has the chest, throat, mesoptychium, and even the under sides of the forelegs densely blackened. In older individuals the black also covers the chinshields. Unique characteristics of obsoleta are the ' pointed posterior margin of the black patch on the ventrals, and the | brilliantly tessellated light-blue-on-dark-blue pattern of the lateral ven- ' tral scales. The tail is bright blue in hatchlings, and vividly striped in all : adults. Despite its extensive geographic range northward through the Exuma Cays chain to Warderick Wells Cay, obsoleta is relatively invariable in color-pattern characteristics. Samples from the northern Exuma Cays exhibit tendencies toward longer retention of the middorsal stripe, and ! more brilliant striping. For example, the middorsal stripe is faintly visible in large males from Sampson Cay (CM 41102, 90 mm. SVL, and CM 41117, 95 mm. SVL). In general, the specimens from Sampson Cay are more brilliantly striped than animals from the Long Island popu- lation. Persistent stripes also appear in the series from Warderick WeUs ' Cay (AMNH 76244-76249) and in a single specimen from Bitter Guana Cay (CM 41070). The general tendency of obsoleta toward reduction of the striped pattern reaches its ultimate expression in a series of speci- mens from Cave Cay (CM 41023-41025, 41040-41045). In the smallest 1970 Ameiva auberi: II. The Bahamian Subspecies 141 animals of this series, males between 65 and 75 mm. SVL, the dorsal field is a uniform gray-brown, the dorsolateral stripes are faintly visible above solid, but emarginate, black dorsolateral fields, and the lateral stripes appear as vague lighter gray areas above the ventrals. In males there is progressive reduction of all stripes and fields, culminating in a virtually uniform gray-brown dorsum separated from the lighter gray sides by a line of black stippling representing the dorsolateral field. The appearance is that of a nearly unicolor lizard. Similiar patterns, resulting from extreme reduction of the dorsolateral fields, are found in occasional specimens of Ameiva auberi thoracica from Eleuthera Island, and rarely in the populations of the northern Ragged Islands (Cochran, 1934). In addition to the variable reduction of the dorsal pattern in obsoleta, there are several constant features of the pattern which also obtain throughout the range of the subspecies. The most important of these is the ventral pattern of adult males. The combination of the reduced black patch on the ventrals, in the shape of a posteriorly pointed V, with the brilliant light and dark blue tessellation of the lateral ventrals, occurs in all populations. A second constant ' character of obsoleta is the presence of a contrastingly colored snout, either noticeably lighter, or of a hue different from that of the sides of the head. In specimens from Long Island the snout is orange in life; in Warderick Wells Cay and Cave Cay animals it is pink in life, and in the specimens from Sampson Cay, it was light gray in life. Scale-count data were analyzed separately for each island in the Exuma Cays chain in an attempt to detect clinal variation along this extensive archipelago, but no significant clinal pattern was found. It is appropriate to mention at this point the published record of Ameiva thoracica ( = auberi) from Crooked Island, across the Crooked Island passage from Long Island ( Cochran, 1934 ) . I have examined the two specimens on which this record is based, USNM 81497 and 81498, collected by Dr. Paul Bartsch in 1930. These adult males have 106 and 110 dorsal granules at midbody, 23 and 25 femoral pores, 30 scales (each) in the fifteenth caudal verticil, and 72 and 79 fourth-toe sub- digital scales. In almost all elements of the color pattern they are identical with males of comparable size from Long Island, a notable exception being the faint but distinct middorsal stripe of both individuals. Because of the virtual meristic identity of these two specimens with Ameiva auberi obsoleta from Long Island, and in view of the failure of recent expedi- tions to find a population of Ameiva auberi on Crooked Island, I am dubious of the validity of the Bartsch record. Of course there is a pos- 142 Annals of Carnegie Museum VoL. 41 sibility that a natural population of auberi occurs on Crooked Island, but it requires verification. COMPARISONS: Ameiva auberi obsoleta occupies a central position geographically on the Great Bahama Bank, and in many apects of color and scutellation obsoleta is central to the other Bahamian races of Ameiva auberi. The basic color pattern of oliveTo-gray dorsal fields and black dorsolateral fields separated by cream-to-yellow stripes is repeated in the Bagged Island population to the south, and in focalis, thoracica, and other more northerly populations. Obsoleta diflFers from both focalis and thoracica in the early obsolescence of the striping and the unique ventral pattern of adult males, and from felis in the unspotted dorso- lateral black fields. From the populations of the Ragged Islands, obsoleta may be distinguished by its tessellated lateral ventrals, less discrete lateral stripes, and spotted lateral fields. Moreover, the Ragged Island lizards generally have a persistant middorsal stripe and more brownish dorsal fields. In scale counts obsoleta finds close similiarity with focalis and thora- cica to the north. Obsoleta is distinct from the northern populations in femoral pores, and overlaps in the other three scale-count characters examined. From the adjacent Ragged Islands subspecies, obsoleta is distinguished by significant differences in mean numbers of dorsal granules at midbody, fifteenth caudal verticil scales, and fourth-toe subdigital scales. Finally, size is a useful character in differentiating obsoleta from geographically adjacent races of Ameiva auberi. Obsoleta, with size maxima of 107 mm. and 71 mm. in males and females respec- tively, is smaller than focalis ( 109 mm. and 80 mm. ) and larger than the Ragged Island subspecies (87 mm. and 75 mm.). Ameiva auberi bilateralis, new subspecies HOLOTYPE: CM 40985, an adult male, from the south end of Great Ragged Island, Bahama Islands, taken July 10, 1965, by Neil D, Richmond. PARATYPES: All from Great Ragged Island, as follows: CM 40984, 40988-40995, ASFS V11363-V11364, same data as holotype; CM 40955-40959, Gun Point, July 9, 1965, Neil D, Richmond.

Flamingo Cay: USNM 81451-81454. DIAGNOSIS: A Bahamian subspecies of Ameiva auberi characterized by a combi- nation of small size (males to 87 mm., females to 75 mm, SVL), moderate number of dorsal granules at midbody, very low number of femoral pores, low number of scales in the fifteenth caudal verticil, and moderate number of fourth-toe sub- digital scales; middorsal stripe usually persistent, dorsal fields brown, dorsolateral fields black and sharp-edged, lateral stripe clear white, broad and vivid, with a 1970 Ameiva auberi: II. The Bahamian Subspecies 143 black lateral field below and above the ends of the ventrals; throat, chinshields, mesoptychium, and anterior half of ventrals black in adult males. DISTRIBUTION: The Ragged Island group, Bahama Islands. Definitely known from Raccoon Cay, Nurse Cay, Great Ragged Island, Little Ragged Island, Flamingo Cay, and Hog Cay. DESCRIPTION OF THE HOLOTYPE: An adult male with the following measurements and counts: snout-vent length 87 mm., tail 174 mm. (complete); dorsal granules at midbody 100; femoral pores 13 and 13 (total 26); 29 scales in the fifteenth caudal verticil; fourth-toe subdigital scales 37 and 37 (total 74). Dorsal ground color and top of head light brown, middorsal stripe visible as a faint trace posterior to neck. Dorsolateral stripes whitish, narrow, not black-edged above. Dorsolateral fields sharp-edged, solid black, continuous from above forelegs onto tail. Lateral stripes dead white, well-defined and sharp-edged, almost as wide as dorsolateral fields. A second black field below each lateral stripe, the two separated by the broad white lateral stripe. All stripes continuous only from foreleg insertion; none starts on head. Chinshields, throat, chest, mesoptychium, under sides of forelegs, and almost half of central ventrals black. Posterior central ventrals smudged with gray, lateral ventrals bluish smudged with black. Under sides of thighs light gray spotted with bluish, dorsal sides of limbs dark brown stippled with black. Tail brown above, with a strong black lateral stripe enclosed in vivid white stripes. Under side of tail gray. VARIATION (See tables): The type series from Great Ragged Island (CM 40955- 40959, 40984-40985, 40988-40995, ASFS V11363-V11364) has the following counts: GAB 97-116 (104.5 ±1.0); femoral pores 20-27 (24.1 ± .27); fifteenth caudal verticil scales 26-32 (28.9 ± .22); fourth-toe subdigital scales 71-82 (76.3 ± .53). Ameiva auberi bilateralis is characterized by the broad, sharp-edged and very white lateral stripes, bordered by intense black dorsolateral and lateral fields. Hatchlings (CM 40994-40995, ca. 32 mm. SVL) have a brilliantly striped pattern, including a broad middorsal stripe continu- ous from neck to tail, slightly narrower dorsolateral stripes originating on the neck, and lateral stripes fully as wide and bright as the middorsal stripe. In adult females the dorsolateral and lateral stripes retain their brilliance, unlike the faded middorsal stripe. The middorsal stripe of adult males is also faded, but remains visible as a gray area in the brownish dorsal fields even in the largest individuals. The dorsolateral fields are intense black in individuals of both sexes and all ages. Old males have slightly emarginate dorsolateral fields. An exception is seen in males from Flamingo Cay (USNM 81451-81454), which have the black fields reduced to a line of spots, and other lineate elements of the pattern faded. The black ventral coloration of males is well developed in individuals as small as 60 mm. SVL (CM 40927) and ultimately extends to cover the chinshields, throat, mesoptychium, and a small triangular area of 144 Annals of Carnegie Museum VoL. 41 anterior ventrals. The remainder of the central ventrals is frequently smudged with black in larger males, and the lateral ventrals are dark blue, with faint suggestions of a tessellated pattern. The series from Nurse Cay (CM 40922-40937) presents several dif- ferences from the Great Ragged Island sample. Nurse Cay lizards have a greater tendency toward loss of the middorsal stripe, and a less pro- nounced lateral light stripe. The dorsolateral black field of the adult males is considerably reduced, as in the Flamingo Cay population. Adult males from Nurse Cay have extensive blackening of the anterior half of the central ventrals. Ameiva auberi bilateralis is probably the smallest of the Bahamian races, smaller even than the diminutive felis. Although less than 40 specimens were examined from throughout the range of bilateralis, the samples contained many adults and a good representation of all size classes. The largest male examined was only 87 mm. snout to vent, and the largest female 75 mm. snout to vent. COMPARISONS: Bilateralis is very similar to the adjacent subspecies obsoleta in many features of color pattern, but is distinguished from obsoleta, indeed from all other Bahamian subspecies of Ameiva auberi, by the brilliant white lateral stripes and development of unmarked black fields below the lateral sti'ipes. Other color characteristics that distin- guish bilateralis from obsoleta are the lack of a boldly tessellated pattern on the lateral ventrals, and a tendency toward longer retention of the striped elements of the pattern. Despite the similarities in the color patterns of obsoleta and bilateralis, these subspecies are strongly differ- entiated in scutellation. Bilateralis is significantly different from obsoleta in dorsal granules at midbody, fifteenth caudal verticil scales, and fourth-toe subdigital scales, and overlaps the range of obsoleta only in femoral-pore-scale counts. Bilateralis occupies a unique position among the southern Bahamian races. Rather than continuing the generally gradual clinal reduction in all scale counts, which obtains from New Providence through Long Island, bilateralis has sharply lower counts which overlap only the populations of Andros Island and the Berry Island and Bimini Island groups in the northern Bahamas. Bilateralis is distinguished from these northern populations by many characters of the color pattern and by size. The Green Cay Population A small series of specimens of Ameiva auberi (CM 40171-40179) was taken on Green Cay on July 18, 1965, by Neil D. Richmond. These lizards constitute something of a zoogeographic enigma, since they resemble 1970 Ameiva auberi: IL The Bahamian Subspecies 145 most closely Ameiva auberi bilateralis rather than the geographically adjacent populations: obsoleta of the Exuma Cays chain and kingi of Andros Island. The Green Cay lizards have a strongly lineate color pattern, with all dorsal stripes persistent throughout life. The middorsal stripe is con- tinuous from the neck to the tail, the narrow dorsolateral stripes originate on the neck, and the lateral stripe is fairly sharp and white. The dorsal fields are gray-brown, the dorsolateral fields are black and emarginate in older adults. The lateral fields are dark gray, neither black as in bilateralis nor spotted as in obsoleta. Adult males have the chinshields, throat, mesoptychium, and anterior two or three rows of ventrals black- ened, and the remaining central ventrals black-smudged. The lateral ventrals are light blue, the under sides of the thighs and tail are white to light gray. The tail is boldly striped. In scutellation the Green Cay population is almost identical with bilateralis in dorsal granules at midbody, femoral pores, and fourth-toe subdigital scales, and has a slightly higher count of fifteenth caudal verticil scales. Of course the sample is too small to be statistically reliable, but meristically the Green Cay population is obviously very similar to, if not identical with, bilateralis. Until a larger sample is available it seems best to withhold formal assignment of the Green Cay population to one of the described subspecies. Nevertheless, the similarity of these lizards to bilateralis suggests that the population has been directly derived from the Ragged Islands. Discussion The land reptile fauna of the Bahama Islands has been the subject of much discussion and speculation because, as a totally derivative fauna in a geologically recent archipelago, it promises to yield concrete data on basic problems such as the potential for overwater dispersal and the evolutionary rates of various species. The earlier literature on the relationships of the land biota of the Bahamas has been sum- marized by Rabb and Hayden ( 1957 ) , who also presented a useful analysis of the complex and as yet incompletely understood geological history of the Bahamas. In a more recent contribution Schwartz ( 1968a) has elaborated on the faunistic relationships and history of the Bahamian amphibians and reptiles. Schwartz's scheme explains the present dis- tribution and origins of the faunas, and helps to place Ameiva auberi in perspective with regard to the other reptile species of the Bahamas. Schwartz postulates early invasion of the Bahamas by Cuban and Hispaniolan faunas, subsequent extinction of this fauna over most of the 146 Annals of Carnegie Museum VoL. 41 Great Bahama Bank with limited survival on peripheral and southern refuges, and the eventual re-invasion of the Great Bahama Bank in late Pleistoeene times. The colonists of this second major wave have invaded the newly emergent lands and old refuges to varying extents. It is with this final group of immigrants that I associate the Bahamian populations of Arneiva aiiheri. The pattern of distribution of Ameiva auheri on the Great Bahama Bank strongly suggests very recent arrival from Guban sources. Auheri has managed to invade most of the central islands of the bank, but is restricted peripherally. Gat Island represents the maximum extent of eastward dispersal, and although the island lies on the edge of the Great Bank, it is only a short distance across a narrow water barrier from Eleuthera Island. Auheri has also reached the Bimini Islands. This might be regarded as an indication of a longer history in the archipelago, but Ameiva auheri richmondi of the Bimini Islands is extremely similar to A. a. multilineata of the adjacent Berry Islands, which suggests that richmondi may be newly arrived on the Biminis. Despite having reached the peripheral Gat Island and Bimini Islands, and isolated interior islands such as Green Gay and Flamingo Gay, the general distribution of auheri on the Great Bahama Bank bespeaks recency. Auheri has failed to extend its range to any of the more isolated large islands at the eastern periphery, such as Gonception Island, Bum Gay, and San Sal- vador Island, and apparently has not crossed the Grooked Island Passage to the south (but see discussion under A. a ohsoleta, above). Most significantly, auheri has crossed none of the relatively narrow water barriers between the northern islands of the Great Bahama Bank and the large islands of the Little Bahama Bank to the north. The exact timing of the invasion, or invasions, of the Great Bahama Bank by Guban Ameiva auheri is not clear. The only concrete evidence lies in the fossils of Ameiva auheri from New Providence Island reported by Etheridge (1966). These specimens, identical with recent species, came from cave deposits assigned to the pre-Pamlico portion of the Wisconsin glacial stage of the Pleistocene. Of the nineteen species of amphibians and reptiles that comprise the Great Bahama Bank herpetofauna, no less than thirteen have been successful in extending their ranges beyond the islands of the Great Bank proper. Seven species have invaded the Little Bahama Bank to the north, using the Great Bahama Bank as a stepping stone, and ten of the thirteen species have either reached eastern peripheral islands, or have crossed the Grooked Island Passage to the south. The remaining species include the proba- 1970 Ameiva auberi: II. The Bahamian Subspecies 147 bly old, Cat Island endemic turtle Chnjsemijs felis, and four species of lizards (including Ameiva auberi) regarded as conspecific witli Cuban stocks. This fairly clear evidence of recent immigration to the Great Bahama Bank is somewhat clouded by the relatively great morphological radiation of the Bahamian Ameiva auberi. The total of eight sub- species of auberi here recognized far exceeds the number of recogniz- able geographic races in other species of the reptile fauna. By compar- ison Leiocephalus carinatus, which has a much larger geographic range, has evolved no more than four Bahamian races (Babb, MS.). Sphaero- dactylus deeoratus has a distribution on the Great Bahama Bank very similar to that of Ameiva auberi, with the single exception that deeoratus has reached Bum Cay. A modern revision of deeoratus admits only three recognizable races on the Great Bahama Bank (Thomas and Schwartz, 1966), although it must be noted that Sphaerodactylus are the master mariners among lizards, and thus the Bahamian populations may be of exceedingly recent origin. Other Great Bank reptiles and amphibians follow this general pattern of relatively little fragmentation into geo- graphic races. The eight races of Ameiva auberi have apparently evolved as isolates during the gradual and successive invasion of various parts of the Great Bahama Bank by over-water dispersal. The obvious recency of immigration of auberi to the Bahamas, and the remarkable morphological radiation which has produced a constellation of well-marked subspecies, underscores the latent variability and evolutionary plasticity of this group of lizards. Both Ameiva and the related genus Cnemidorphorus contain many notoriously labile species. In topographically diverse land masses and in island archipelagoes this lability is expressed in the formation of numerous relatively divergent geographic races. The only comparable situation outside the family Teiidae of which I am aware is the explosive radiation of some species of the lacertid genus Laeerta on islands and archipelagoes in the Med- iterranean Sea. 148 Annals of Carnegie Museum VoL. 41 Fig. 1.

DISCUSSION Albert Schwartz^ Research Assoeiate, Section of Amphibians and Reptiles Carnegie Museum, Pittsburgh, Pennsylvania With the description of 24 Cuban subspecies and eight Bahamian subspecies of Ameivci aiiberi Cocteau, the species has now been shown to be extremely polytypic and genetically plastic. Such diversity may be surprising to some readers, but actually it is to be expected. The geographically correlated variation of the three Hispaniolan species (Ameiva chnjsolaema, A. taeniura, and A. Uneolata), whose study preceded tlie present one on A. auberi, has served in a way as a prec- edent. The study of the Hispaniolan species indicated that on at least one of the Greater Antilles the genus Ameiva has differentiated on the subspecific level in response to edaphic and geographical isolating factors. Although Cuba does not present the topographic and physiographic diversity of Hispaniola, it is nonetheless far from a flat, featureless and topographically uniform plain over which Ameiva auberi is neatly and evenly distributed. The response of some Cuban reptiles (notably Anolis equestris in Oriente Province; Schwartz, 1964b) to often-dramatic ecological differences and geo- graphical isolating features, by the development of distinct subspecies, is well known. Considering also that: Cuba is an elongate island (about 1200 kilometers long with a maximum width of from 35 to 200 kilometers); there are several extensive chains of cays associated both with it and the Isla de Pinos; Cuba varies ecologically, from extremely arid coasts to mesic forested mountainous highlands with elevations to 2005 meters (Pico Turquino); and that there are many ranges and massifs with lesser but still respectable heights and areas, it is not surprising that Ameiva auberi varies greatly in several char- acters in a geographically correlated manner. As far as variation in the Bahamian archipelago is concerned, this too is expected, consid- 1 Miami-Dade Junior College, Miami, Florida 33167 152 1970 Ameiva auberi; III. Discussion 153 eriiig both the plasticity of A. auberi on Cuba and the (at least presently) completely disjunct nature of many of the Great Bank islands that are inhabited by the species. Apparently the closest relative of A. auberi is A. dorsalis Gray from Jamaica. In Barbour and Noble's revision of Ameiva (1915:425), dor- salis, thoracica, and auberi are keyed out together. Examination of specimens of A. dorsalis shows that the Jamaican species has many resemblances to A. auberi insofar as scutellation is concerned. Both have 10 transverse rows of ventral scales and comparable numbers of longitudinal rows of ventral and fourth-toe subdigital scales. There are, however, trenchantly different features of scutellation in A. dor- salis (greater number of femoral pores, much smaller dorsal granules, much less enlarged preantebrachials, differences in scutellation of the temporal region) which I regard as being of specific rather than sub- specific value. Thus, A. dorsalis is to be regarded as a species distinct from A. auberi. That dorsalis is related to auberi is attested by the gross similarity of dorsal pattern (a median dorsal pale longitudinal area, pointed anteriorly, which gradually expands as it progresses posteriorly to embrace the base of the tail) to that of some of the eastern Cuban subspecies of A. auberi, namely sabidicolor and granti. Such resemblances may well be fortuitous, but on the other hand no other West Indian Ameiva has this type of median dorsal marking. The proximity of Jamaica to the southern Oriente coast (about 150 kilometers) seems to reinforce these resemblances as indicators of relationship. Barbour and Noble (1915:422), in their schema representing the relationships of the West Indian and continental species of Ameiva, suggested that auberi and dorsalis were distantly and independently derived from A. undulata of Middle America, that thoracica is closely related to auberi, and that dorsalis is directly related to A. chrijso- laema of Hispaniola. At the moment I do not agree with this latter relationship. Certainly dorsalis is much more closely related to auberi than to chrysolaema. Barbour and Noble also suggested that A. taeni- ura {=A. lineolata sensu Barbour and Noble) is a distant relative of auberi. This relationship seems more plausible, although it is now generally accepted (Cochran, 1941:273-274) that taeniura is more closely related to A. polops of St. Croix, and thence to A. maijnardi in the southeastern Bahamas and A. tvetmorei in Puerto Rico. These three species have the dorsal caudal scales with oblique keels, although this character is least definitely shown in taeniura. 154 Annals of Carnegie Museum VoL. 41 It seems likely that dorsalis-auberi (ineluding thoracica) and pos- sibly chrysolaemci represent a single stock of western Greater Antilles ground lizards, of which dorsalis has been long isolated on Jamaica. Ameiva aiiberi has been long in residence on Cuba and the Isla de Pinos, and is a recent arrival in the Bahamas. A. dorsalis merits spe- cific status, whereas thoracica does not. Savage (1966:742-743) has suggested that A7neiva and Cnemido- phoriis represent, respectively, South American and Middle American derivatives of a common ancestral stock. These two genera evolved separately in areas north and south of the Isthmian Link. In the late Cenozoic, with the closing of the Isthmus of Panama, Ameiva invaded CenLal America and Cnemidophonis South America, with limited evolution in the newly invaded area in each case. If such a history is essentially correct (and the continental data support it), a relation- ship between A. tindidata and auberi-dorsalis-{?chrysolaema) seems less likely. Final and “permanent” closure of the Isthmian Link took place in the Pliocene, although prior to that time there had been a series of stepping-stone islands scattered between South America and Mexico. It is possible that a South American Ameiva stock reached Middle America sometime earlier, during the Cenozoic, and thence reached Cuba (and later, Jamaica, and still later, the Bahamas). In fact, the diversity of Greater Antilles Ameiva (contrast for example such species as A. ehrysoJaema and A. lineolata on Hispaniola, or even such dissimilar species as A. maijnardi and A. auberi, occurring on islands in or near the same archipelago) makes it seem very unlikely that this high degree of differentiation on the species level has oc- curred since Pliocene, or later, invasion of the Greater Antilles from the continent. On the other hand, considering the diversity of Lesser Antilles Ameiva (see Baskin and Williams, 1966, for an incisive discussion), it seems more likely that all Antillean Ameiva are related to one or more South American stocks. It also seems likely that the Antilles as a faunal region has been colonized by leap-frogging and island- hopping, primarily by South American stocks. Such a history, being independent of the Isthmian Link events, would allow sufficient time for Ameiva to have reached many of its Antillean outposts. Although absent in the Gayman Islands and some of the northern and south- eastern Bahamas, Ameiva is one of the most widespread reptilian genera in the Antilles, exceeded in total distribution only by Anolis and Sphaerodactylus. This history would also allow sufficient time for 1970 Ameiva auberi: III. Discussion 155 the various major “kinds” or “styles” of Ameiva to have evolved. And it would not demand that the great specific and subspecific diversity of the western Caribbean Ameiva be accomplished more or less synchronously since the Pliocene. Along these lines, it is pertinent that presumably the Great Bank in the Bahamas was inundated throughout the Pliocene and variably or partially submerged during the Pleistocene (Babb and Hayden, 1957:8). This implies that all the Bahamian subspecies of A. auberi have had a very recent origin (at least post-Pliocene, and possibly even more recent) since the Great Bank was generally not available earlier for colonization from Cuba. The same statement is true of some of the Cuban subspecies; extraria, extorris, zugi, and galbiceps occupy low cays and islets that were inundated during the Pliocene. These cays and islets could not have been invaded from the Cuban mainland or the Isla de Pinos until after they emerged from the ocean. The total history of A. auberi in the Bahamas and Cuba indicates, by the very recency of some of the land, masses occupied by quite distinctive subspecies, that there had long been a resident stock of Ameiva (presumably remotely derived from South America) on Cuba. There diversification occurred, and at an early date, by overseas transport, Ameiva arrived in Jamaica (probably from eastern Cuba). At a much later date, Ameiva reached the Bahama Islands' Great Bank. I suggest the derivation of dorsalis from auberi, rather than the reverse, because dorsalis is relatively constant in its pattern features throughout Jamaica, suggesting that it is the derived rather than basic species of the auberbdorsalis pair. Given a long period of residence of A. auberi on Cuba and the ecological, physiographic, and geographic diversity of Cuba as well, the subspeciation of A. auberi there is expected. The eastern sub- species (of which it has been noted that sabidicolor and granti are rather like A. dorsalis in dorsal pattern) seem to have retained the original style of dorsal pattern of the basic stock. The expanding and fading median dorsal line, in fact, is a general feature of A. auberi from northeastern Camagiiey to Cabo Cruz (although ustulata on the south-central Oriente coast has diverged from this basic Oriente pat- tern) in the subspecies sublesta, citra, granti, sabidicolor, and hardyi. These races presently (with the exception of sublesta and citra) are associated with coastal regions bounded by interior mountains. It seems possible that all the eastern subspecies from sublesta to hardiji represent radial derivatives from one ( or several ) eastern mountainous 156 Annals of Carnegie Museum VoL. 41 areas that served as refuges in Plioeene-Pleistocene time. Subsequent differentiation along the coast has resulted in the development of the large and orange-throated southwestern hardiji (whereas the more east- ern subpecies mtiilata, sabiilicolor, and granti are black-throated) and the geographically intermediate ustulata, which lacks the expanding and fading dorsal line. The extreme peripheral members of this group, citra and the insular but closely adjacent sublesta, are subspecies that i are farthest removed from any eastern massif but presumably were derived from such areas (see Fig. 1 for a graphic rendition of these and the following statements). The central Camaguey subspecies Uanensis is allied most closely to galbiceps from the Cayos de las Doce Leguas. The apparent absence of Ameiva from most of Camagiiey Province has been previously mentioned (Schwartz, Section I), and it has been admitted that this absence may be more apparent than real. The Doce Leguas cays are low and surely would have been inundated with any appreciable rise in sea level. Thus colonization of these islands must have taken place since their last emergence from the sea. The occurrence on the Doce Leguas cays of two endemic subspecies of lizards, as well as other reptiles (one of which, Sphaerodactijhis argus, is purely Jamaican in origin) indicates that sufficient time has elapsed since the appearance of these cays above the ocean surface to allow not only the arrival of Cuban reptiles there, with subsequent racial differentiation, but the waif arrival of a Jamaican reptile also. Presumably, despite the i present absence of Ameiva from the adjacent Camagiieyan coast, galbiceps and Uanensis represent common derivatives of an ancestral Cuban form. The patterned dorsal fields and non-black throats ally these two races. Turning to the extreme western end of Cuba and the Isla de Pinos, there are two major groups of subspecies involved: (1) the very large and yellow-throated procer with a relatively wide distribution, and (2) the smaller races cacuminis, denticola, patdsoni^ secta, marcida, and ziigi. Of the second complex, paulsoni-sectamiarcida-ziigi repre- sent a southern Pinar del Rio-Isla de Pinos-Archipielago de los Canarreos group. The floral and faunal relationships of Pinar del Rio to the Isla de Pinos have been pointed out repeatedly (Schwartz, 1959a: 138; 1959b: 61; 1959c: 118), and it is not surprising that the subspecies of Aiiieiva in these two regions show similarities. Of the four races, paulsoni and zugi (usually with non-black throats, and zugi with its extreme obsolescent dorsal pattern) are the most divergent. It 1970 Ameiva auberi: III. Discussion 157 must be recalled, however, that marcida on the southern Isla de Pinos is apparently in the process of losing the black-throated condition, and that one population of otherwise pale-throated ziigi (Cayo Candles) contains some black-throated individuals. There seems little doubt that zugi has been derived along the Archipielago de los Canarreos from the adjacent and partially black- throated marcida. Possibly this group of four subspecies represents radial dispersal from an Isla de Pinos haven, paulsoni having arrived in its present south Cuban coastal area by overseas transport or by overland dispersal while the Isla de Pinos and Cuba were connected, and marcida having differentiated from secta on the southern third of the Isla de Pinos (because of the intervening Cienaga de Lanier) at a more recent date, with zugi a derivative of marcida on the Archipielago. Even slight rises in sea level would bring about division of the Isla de Pinos into two separate islands, and this may have helped reinforce the genetic distinction of secta and marcida from each other. The distribution of procer, centering as it does in the Sierra de los Organos, would indicate that it has had a long, independent history in this range, which was part of the Cuban archipelago during Pliocene-Pleistocene time. Since restoration of the surrounding low- lands, procer has expanded its range into the lower areas surround- ing the Sierra de los Organos and has reached as far to the southwest as the base of the Peninsula de Guanahacabibes and as far east as Cabanas. The two Guanahacabibes subspecies, denticola and cacuminis, have been discussed in detail previously ( Schwartz, Section I ) . It is difficult to associate denticola with its adjacent neighbor procer, and denticola is better regarded as a western derivative of the paulsoni (and thus indirectly of secta ) stock, with cacuminis as either a terminal or north- ern peninsular coast population with non-black throats. To the east of the range of procer, there is a series of northern coastal subspecies from Habana Province to Las Villas Province {auberi- pullata-gemmea-garridoi) of which one (pullata) has a black chest and throat patch. In addition to these subspecies, ahducta occupies the Peninsula de Hicacos, and extraria and extorris occur on the Archipiel- ago de Sabana, off the northern Las Villas coast. The same style of throat and chest coloration and pattern as pullata occurs in the south- ern Las Villas atrotliorax, whereas the latter’s closest geographic rela- tive is peradusta, a subspecies that carries ventral blackening to an extreme in the species. A. a. atrotliorax occupies that part of the 158 Annals of Carnegie Museum VoL. 41 southern coast immediately adjacent to the high Sierra de Trinidad, whereas the north coast races occupy in general the coasts adjacent to more interior uplands — the Escaleras de Jaruco, the Sierra Morena, and the Sierra de Jatibonico. A single subspecifically unidentifiable specimen from northeastern Las Villas is from the Sierra de Jatibonico, and the small series from north of the Sierra de Cubitas completes the records of Ameiva from this northern coast between Habana and central Camagiiey provinces. The occupation of lowlands immediately adjacent to interior uplands on both north and south coasts (of these subspecies, peradusta, which I consider an atrothorax derivative, is the farthest removed from any immediately adjacent montane mass) of central Cuba suggests that in each case the more or less widespread Ameiva had been forced to retreat during extensive Pleistocene inun- dation to a series of disjunct islands, whence it subsequently expanded with emergence of surrounding lowlands. If such is the case, then auheri and pidlata may have been derived from an Escaleras de Jaruco population, with the peripheral a])duct(i evolving on an offshore island which is today the Peninsula de Hicacos, gemmea and garridoi from j the Sierra Morena (or possibly garridoi from the Sierra de Jatibonico), and atrothorax (and, more removed on the west side of the Bahia de Cienfuegos, peradiista) from the Sierra de Trinidad. The differences pointed out between coastal ])idlata and the few specimens from the interior of Matanzas Province at San Miguel de los Banos may indi- cate that these latter have been derived from still another isolated , population on the Bejucal-Madruga-Limonar anticline, in which range San Miguel lies. The similarity in chest and throat pattern between the north coast puUata and the south coast atrothorax may be inter- preted (in this area) as the retention of a primitive throat pattern by two presently disjunct populations which previously may have been continuous across the area now occupied by the La Habana-Matanzas Red Plain (Llanura roja la Habana-Matanzas; see Marerro, 1951:474 et seep), and across which these two races may have restablished contact. The general association of Cuban A. auheri with lowland coastal regions allied to nearby mountains, and the contention that these ad- jacent mountains were insular refugia during the period when Cuba || was an archipelago, support the differentiation of A. auheri into a series of races, these races having been at least partially differentiated j during the period of inundation of the lowlands. The fact that the center of distribution of one race (proeer) is still primarily in the 1970 Ameiva auberi: III. Discussion 159 interior uplands lends added support to this theory. The only serious exceptions to the montane refiigia are llanensis in Camagiiey Province, and caciiminis and denticola on the Peninsula de Guanahacabibes. The latter two races, as has been pointed out, may be more recent western derivatives of paulsoni (and its Isla de Pinos relatives), whereas llanensis occupies an interior region adjacent to the Sierra de Cubitas. If the unnamed population north of the Sierra de Cubitas is presumed to represent the original residual Cubitas population, then llanensis can hardly also be so considered. In southern Camagiiey Province is the Sierra de Najasa. This range is geographically intermediate between the distribution of llanensis and the Doce Leguas subspecies galhiceps, and possibly llanensis represents the Najasa isolate that has subse- quently invaded the north as far as the Sierra de Cubitas and also reached the Laberinto de las Doce Leguas. As I mentioned above, it is obvious that some insular subspecies of A. miheri (extmria, extorris, ziigi, galhiceps, and possibly siihlesta) have had more recent development and differentiation from their main- land relatives. These races are in most cases closely related to the subspecies on the adjacent mainland: i.e., snhlesta to citra, zugi to marcida, and galhiceps to llanensis. The differences between extraria and gemmea, however, are much greater than those between the above racial pairs. Considering the long and linear extent of the north coast caijeiia from Piinta Hicacos in the west to Cayo Sabinal in the east, and considering that Cayo Sabinal is inhabited by the westermost member of the Oriente complex of races, it is possible that extraria (and extorris, which is a local derivative of extraria) has been derived by serial colonization and invasion of the northern cayeria from the east, rather than from the coast directly to the south. The resemblances between extraria and the eastern subspecies are such that extraria may well be more closely related to suhlesta and citra than the more geographically dose gemmea and garridoi. If the above interpretation of the history of Ameiva in Cuba is correct, then the suggestion that the distribution of A. aiiheri, com- posed of widely disjunct populations separated by at times broad areas where no ground lizards are known, is a relictual one is reinforced. Those areas from which no Ameiva are known are thus interpreted as regions that A. auheri has not yet penetrated. These regions generally are also farthest removed from montane refugia. Although A. auheri is absent today from some regions like the highlands of the Sierra Maestra and extreme eastern Oriente because of ecology and elevation, 160 Annals of Carnegie Museum VoL. 41 the absence of the species from other apparently suitable areas may be explained by this suggested history of the species in Cuba and the Isla de Pinos. Considering the Bahamian subspecies as a whole (see McCoy, section II, for details), the consistency of presence of black throat and chest pigment (reduced but still present in focalis) suggests that the parent Cuban population of the Bahamian stock was black- throated, and logically would be from the northern Cuban coast. The closest present point of the Bahama Islands and Cuba is along the southwestern arm of the Creat Bahama Bank paralleling the Camagiiey caijena between Cayo Coco and Cayo Cuajaba. Here the Great Bank is separated from Cuba by the narrow (50 kilometers) but deep (locally to over 1000 fathoms) Old Bahama Channel. At this closest point of the Cuban insular platform and the Great Bahama Bank, there are but two tiny and remote Bahamian islets ( Guinchos Cay and Cay Lobos) that are not known to harbor Arneiva. To the east, along the southeastern margin of the Great Bank and about 110 kilometers north of Cabo Lucrecia in Oriente, lie the southernmost Bahamian islands with any considerable land mass, the Ragged Island group. Arneiva a. hilateralis, one of the most distinctive of the Bahamian subspecies, occupies these islands. It might be expected that hilateralis would be like one of the north Cuban coastal subspecies. Arneiva auberi granti, by virtue of its occur- rence from Banes eastward to Baracoa, would be a logical Cuban possibility. A. a. granti is also black-throated, which would satisfy one of the pigmentary requirements of a Cuban ancestor for the Bahamian lizards. Along the northern Cuban coast, other black- throated subspecies are pullata and extorris. The former lies far to the west in Matanzas Province and the latter has a limited distribution on one of the cays of the Archipielago de Sabana. The two other eastern Cuban north-coast races, sublesta and eitra, have colored throats. Despite the proximity of granti and hilateralis, these two subspecies have little in common other than throat and chest color. A. a. hilateralis is a pale but distinctly lined subspecies with broad, sharp-edged and white lateral stripes bordering black lateral fields. The dorsal stripe is present but faded, maintains its intensity and width for the length of the dorsum, and does not become progressively fainter and wider as is proceeds posteriorly. A. a. granti on the other hand is a rich reddish brown above, has a yellow and contrasting median dorsal 1970 Ameiva auberi: III. Discussion 161 line which expands and becomes paler posteriorly, narrow and often fragmented dorsolateral lines, and lateral fields with scallops or internal spotting. A. a. bilateralis is generally faded in aspect with boldly contrasting solid black lateral fields, whereas A. a. gra7'iti is a richly colored and brightly patterned lizard. Two subspecies could hardly be more different in pattern and color than these two. As far as meristic data are concerned, bilateralis and granti have identical means (75.9) of fourth-toe scales and comparable means of femoral pores (24.1 and 25,7), but bilateralis has a higher mean number (28.7) of fifteenth verticil scales than does granti (25.1). All things considered, Cuban granti and Bahamian bilateralis seem not to be closely related. Of the north Cuban coast subspecies, bilateralis most closely resem- bles extraria and extorris. Of this pair, extorris is black-throated but is known to occur on only one islet. All three subspecies are faded in appearance, but extorris has an unpatterned dorsum and extraria has a yellow median dorsal line that fades posteriorly. Finally, both extraria and extorris lack lateral fields, quite in contrast to the prominence of these features in bilateralis. Of the three subspecies, the means of fourth-toe scales in extraria (76.3) and bilateralis (75.9) are compara- able, whereas that of extorris is much lower (69.5). The series of ex- torris is small, however. Femoral pore means (24.1 in bilateralis, 23.8 in extraria, 25.3 in extorris) are variable, with bilateralis intermediate between the two Cuban subspecies, and means of fifteenth verticil scales (28.7 in bilateralis, 26.5 in extraria, 25.4 in extorris) show that bilateralis exceeds both Cuban subspecies in this count. It is interest- ing to note that, of the Bahamian subspecies, bilateralis ranks next to last in fifteenth verticil means (range of Bahamian means 28.3 to 31.6). Means of fifteenth verticil counts in all Cuban subspecies vary from 24.9 to 29.5. Thus, in general Cuban subspecies as a group have fewer scales in the fifteenth caudal verticil than do Bahamian subspecies as a group. The low fifteenth-verticil mean of bilateralis suggests that, of all the Bahamian races, it may indeed be most closely related to the Cuban stock. Everything considered, the differences between the pertinent north Cuban coastal subspecies of A. auberi and the most southern of the Bahamian subspecies, bilateralis, suggest that the Ameiva invasion of the Great Bank may well have been along that section of Cuba that most closely approximates the Great Bank today, i.e., the northern cayeria between Punta Hicacos in Matanzas and the Bahia de Nuevitas. At least there are some similarities between some of the subspecies 162 Annals of Carnegie Museum VoL. 41 along this coast and bilatercilis. Although the Ragged Islands are elosest geographically to the Oriente coast, there is little similarity between hilateralis and granti. This postulated relationship is of eourse questionable. Resemblances between extraria and hilateralis may be due to responses to small-islet environments and more arid conditions. It should be recalled that granti occupies one of the wettest and most densely forested portions of Cuba, whereas extraria inhabits a series of cays that are open, more or less arid, and lack dense forests. It is pertinent that ziigi, a sub- species of the exposed and dry islands in the Archipielago de los Canarreos, is also pale. Remarkably, of all the Cuban subspecies, hilateralis most closely resembles the far-removed zugi. Of the pale and faded Cuban subspecies, only zugi regularly retains the black lateral fields. This surely is an instance of convergence. McCoy ( section II ) has commented succinctly on the evolution and radiation of A. auheri within the Bahama Islands themselves. In the Bahamas, Ameiva occupies solely the Great Bahama Bank and has not succeeded in invading the Little Bahama Bank or in crossing the Crooked Island Passage. It has reached Cat Island, which is peripheral to the Great Bank proper. The remarkable vagility of A. auheri is demonstrated by its ability to reach some remote islets on the bank. Green Cay and the Bimini Islands are two striking cases in point. Of the Bahamian subspecies, kingi, richmondi, and multilineata seem to form a rather eompaet group of predominantly lineate subspecies that occupy islands to the west of the Tongue of the Ocean dividing the Great Bank into two nearly equal portions. To the east of the Tongue of the Ocean, thoracica, felis, and focalis form a less integrated group, with felis most divergent in dorsal and lateral pattern. A. a. ohsoleta might also be included with this assemblage. A. a. hilateralis stands alone in its strikingly contrasting dorsal pattern, although it too is probably related to the eastern Great Bank subspecies, most closely to the adjacent ohsoleta. There seems little reason to reject a hypothesis that the Bahamian subspeeies represent two basie stocks (but not likely two different invasions) that were early separated by the Tongue of the Ocean. After this early division, distinctive subspecies on each island or island group evolved. A. a. felis requires speeial comment. This subspecies occupies the only island (Cat) peripheral to the Great Bank (although there must have been a former connection, in contrast to several remote Bahamian Islands that have never been connected) inhabited by A. auheri. Me- 1970 Ameiva auberi: III. Discussion 163 Coy (section II) stated that felis stands alone among the Bahamian races in that it possesses spotted lateral fields. Patterned lateral fields are of regular occurrence in many Cuban subspecies, however. The occurrence of this character in felis, so far removed geographically from Cuba and separated from it by the two intervening subspecies ohsoleta and hilateralis is especially intriguing. Considering the isolated position of Cat Island in reference to the Great Bank and its member- ship in the eastern seaward volcanic arc, the resemblance of felis to some Cuban subspecies in this character may be of added significance. It seems possible that the Cat Island A. auberi have had a somewhat different history from the balance of the Bahamian subspecies. Detailed studies of two other Bahamian reptiles (Sphaerodactijlus cleeoratus, Thomas and Schwartz, 1966:7; Thomas, 1968; Anolis distiehus, Schwartz, 1968b) have shown that the Cat Island populations are peculiar and neither readily assignable to adjacent subspecies nor sufficiently and constantly divergent to be regarded as nomencla- turally distinct. In both cases the Cat Island populations show peculiar admixtures of characteristics of populations from adjacent islands. The contrast between the situation in S. decoratus and A. distiehus on one hand, and A. auberi on the other, is quite striking in this regard, since felis is an exceptionally distinct subspecies. Apparently the reptile fauna of Cat Island has had a varied history, and presumably this is due to the location of Cat, peripheral to the Great Bank mass itself, and possibly to a geological persistence it may have enjoyed. In summary, I interpret the history of Ameiva auberi as follows. A pre-auberi stock arrived on Cuba from South America, by island- hopping and overseas transport, at some early date. Evolution of this stock into subspecies began on Cuba, and differentiation was aided by the successive partial inundations that occurred during Cuba’s geologi- cal history, resulting in archipelagos variously formed and later vari- ously recombined. Sometime in its history, Ameiva reached Jamaica, probably from the southern Oriente coast, and in Jamaica arose A. dorsalis. During the Pliocene-Pliestocene, Cuba was once more a series of islands, which the present montane masses roughly outline. On these islands, Ameiva continued its local evolution, and with the recession of the seas and final emergence of the Cuban lowlands, the lizards were able once more to recolonize not only the resultant low- lands but also to reach the Great Bahama Bank from the northern Cuban coast in the region between Las Villas and Camagiiey. With establishment of Ameiva in the Cuban lowlands from montane refugia, 164 Annals of Carnegie Museum VoL. 41 various subspecies have evolved because of isolation and intensifica- tion of differences that had their inceptions while the lizards occupied their Pleistocene refugia. On the Bahama Islands, two (or perhaps three) basic stocks have resulted in two major divisions of the sub- species of those islands, one east of, the other west of, the Tongue of the Ocean. I interpret all extant subspecies of A. auheri as being quite recent in development. Such an interpretation is mandatory since much of the land area now occupied by A. auheri has been permanently available only since the Pleistocene. 1970 Ameiva auberi: HI.

Miller^ Research Associate, Section of Insects and Spiders, Carnegie Museum, Pittsburgh, Pennsylvania This is the seventh of a series of papers based on the Margaret M. Cary — Carnegie Museum Expedition to Bafa California, Mexico, 1961, to appear in the Annals of Carnegie Museum. For an account of the itinerary and description of localities, see the first paper in this series [Richard M. Fox, Ann. Carnegie Mus., 36 (16): 181-192], Except as noted, all specimens including type series discussed in the following study are in the collection of Carnegie Museum. Introduction The Hesperiidae of Baja California have been reviewed] by MacNeill (1962). This paper adds locality records and confirms the occurrence in the Cape region of some poorly known skippersL.,Jwo|^additipna4 species are added to the list of peninsular skippers, the rare Tlwryhes Valeriana (Plotz) and Pyrgus o.^oileus (Linne). Two new peninsular subspecies were described in a preceding paper (Miller and MacNeill, 1969). The list of hesperiids is by no means complete; there is still an undescribed subspecies of Paratrytone melane (Edwards) in the high mountains south of La Paz; Prenes californica A. G. Weeks is still an unknown butterfly; possibly there are other species of Erynnis in the mountains. And the spring skipper fauna has been poorly sampled. The Expedition personnel collected 1558 hesperiids of 87 species. Of these, 411 specimens of 81 species were taken on the mainland, and 1147 specimens of 26 species collected on the peninsula. Four of these species are represented by separate mainland and peninsular subspecies. In addition to the Expedition material, I have examined a small number of skippers from the San Diego Natural History Museum, and these are reported under the appropriate species below. ^Allyn Museum of Entomology, 712 Sarasota Bank Building, Sarasota, Fla. 33577. Issued September 25, 1970 169 / 170 Annals of Carnegie Museum vol. 41 I wish to express my appreciation to the late Dr. Richard M. Fox and to Harry K. Clench of the Section of Insects and Spiders, Carnegie Museum, for their encouragement and suggestions. Dr. C. Don MacNeill identified some specimens for which we had no comparative material, and generally was most helpful. Thanks go to Dr. C. F. Harbison, San Diego Natural History Museum, for the loan of specimens. Finally, the greatest thanks are due Mrs. Margaret M. Cary of Philadelphia, Penn- sylvania, for making this study possible by sponsoring the Expedition. Zoogeography, Cape Region Hesperiidae The occurrence outside the Cape region of the Hesperiidae thus far recorded from there is summarized in Table 1. From these data it becomes apparent that not all the skippers in the region were derived from the same geographic source, nor were they simultaneous arrivals at the tip of the peninsula. The 28 species show five general distribu- tional patterns, which are summarized below. 1. Basically temperate species showing affinities to the California mountains. There are two of these species known from the tip of the peninsula at present, both in the high mountains of the Sierra de la Laguna. When these mountains become better collected, particularly in the spring, the number will probably increase. Roth species are represented in the Cape region by endemic subspecies, Erynnis tristis pattersoni Rums, and an unnamed subspecies of Paratrytone melane (see MacNeill, 1962: 110-111). These two primarily temperate skippers have also managed to penetrate the Mexican highlands, with melane extending as far south as the Cerro de la Muerte in Costa Rica. The differ entation shown by these butterflies in the Cape region indicates long isolation from their northern relatives, and their temperate habitat on the peninsula suggests that they arrived at a time when the peninsula was moister and perhaps cooler than at present. Truxal (1960: 168) discusses the post-Miocene extension of the Arcto- and Madro-Tertiary geofloras into the peninsula, and it seems likely that the introduction of tristis and melane into the Cape region was synchronous with this event. 2. Sonoran desert species neither found in southern California nor significantly penetrating the tropics. There are five of these species: Thoryhes valeriana (Plotz), Systasea zampa (Edwards), Pyrgus philetas Edwards, Nastra neamathla (Skinner and Williams) and Lerodea dysaules Godman. The lack of differentiation of the Cape region populations of these species indicates some interconnection with 1969 Miller: Mexican Hesperiidae 171 TABLE 1 Distribution of Hesperiidae Species of the Cape Region Showing Endemicity OF Cape Fauna Species Distribution Outside Cape Region BCN sc CM AM ASD MH SM SA Chioides catillus a a a a b Urhanus proteus a? a a a a a a a dorantes ? b b b b b Thorybes valeriana a a?

In either event, these skippers are probably later, perhaps even post-Pleistocene, arrivals. All are lowland butterflies. 3. Sonoran desert species that have penetrated California but not the tropics. There are four of these species: Staphylus ceos (Edwards), Pholisora catullus (Fabricius), Copaeodes aurantiaca (Hewitson), and Polites sahuleti (Edwards). One of these is represented by an endemic Cape region subspecies, Polites sahuleti margaretae Miller and Mac- Neill, but the peninsular populations of the other three species are indistinguishable from their mainland counterparts. P. sahuleti inhabits the coastal grasslands on the peninsula, while the others are of more general occurrence in the lowlands. All are probably fairly recent arrivals on the peninsula. P. sahuleti is a well-known polytypic species. ill 172 Annals of Carnegie Museum vol, 41 « !! whereas the others have no presently recognized geographic isolates. 4. Sonoran desert, and humid or subhumid, tropical species not found 1 in southern California. There are eight species in this group: Chioides catillus (Cramer), Cogia hippalus (Edwards), Chiomara asychis li (Stoll), Pyrgus oileus (Linne), Heliopetes domicella (Erichson), H. |j laviana (Hewitson) and Amblyscirtes tolteca Scudder. This group is I second only to Group 1 in degree of endemism. Three of the species have endemic Cape region subspecies, Urbanus dorantes calafia (Wil- i liams), Cogia hippalus peninsularis Miller and MacNeill, and Chiomara asychis pelagica (Weeks), and the peninsular populations of catillus and laviana may be distinguished from their mainland relatives by differ- , ences too slight to warrant naming them. Fives species, catillus, laviana, | domicella, asychis and oileus, are also represented in South America ! by different subspecies, while tolteca has two subspecies in Mexico: the i, nominate one in southern Mexico and prenda Evans in Sonora. Most, | if not all, these species are earlier arrivals in the Cape region, probably post-Miocene and certainly pre-Pleistocene. 5. Widely distributed tropical and subtropical species. There are eight species in this category lUrbanus proteus (Linne), Erynnis fune- ralis (Scudder and Burgess), Pyrgus communis (Grote), Hylephila phyleus (Drury), Atalopedes campestris (Boisduval), Lerodea eufala ' (Edwards) Calpodes ethlius (Stoll), and Panoquina panoquinoides (Skinner). None of these has an endemic Cape region subspecies, and in only one species (panoquinoides) can the peninsular material be ^ distinguished from either Mexican or Californian specimens. P. pano- * quinoides is unique in the group as a colonial butterfly intimately associated with coastal or even salt-marsh grasses. Five of the other I members of the group, proteus, phyleus, campestris, eufala, and i ethlius, are strong-flying tropical skippers that have been taken as far I north as the northern United States, but they probably are not resident : there. These species arrived in the Cape region, probably in recent i times, either over water or via land, through the Sonoran desert. C. ethlius, though, is so intimately associated with cannas wherever it is found that it is impossible to ascertain whether it actually arrived in the Cape region under its own power or was imported by man with his ornamental cannas. No specimens were taken on the peninsula except in canna gardens. The other two species, E. funeralis and P. communis, are widespread butterflies which certainly arrived recently, probably by way of the Sonoran desert. 1 1969 Miller: Mexican Hesperiidae 173 In summary: all members of Group 1 are represented by endemic subspecies derived from the California mountains, and they probably date from the post-Miocene floral invasion of the peninsula; all members of Group 2 are recent arrivals from the Sonoran desert; the members of Group 3 arrived fairly recently from the Sonoran desert, although sabuleti may be an earlier immigrant; the members of Group 4 are early arrivals from the Sonoran desert, as evidenced by their distinct- ness from mainland populations; and the Group 5 skippers are recent arrivals of widely distributed, strong flying species, one of which, ethlius, may have been introduced by man. Systematic Account In the following account, no attempt has been made to separate the peninsular from the mainland skippers, except by separately listing the records from the various Mexican states. I have listed the material that was available from the San Diego Museum of Natural History separately at the end of the discussion. Subfamily Pyrrhopyginae Mysoria affinis (Herrich-Schaffer), 1869. This skipper is known from the western lowlands of Mexico and occurs infrequently in Guatemala (Evans, 1951: 69). It was not taken on the peninsula; indeed, no pyrrhopygine is known from there. SINALOA: 16 mi. north of Mazatlan, 1 $ 29-x. Subfamily Pyrginae Phocides pigmalion belus Godman and Salvin, 1893. Evans's description (1952: 13) of this Mexican subspecies mentions . . costal spot over cell spot vestigial." While this description applies to males, the females have the costal spot well developed. This skipper is not common in collections. SINALOA: Mazatlan, 2$ 1$ 24-x, 1$ 26-x. Proteides mercurius mercurms (Fabricius), 1787. The single specimen taken by the mainland party is in all respects referable to the mainland subspecies of this skipper. The species is general throughout the Neotropics. SINALOA: Urias, 2 mi. south of Mazatlan, 1 $ 31-x. Epargyreus exadeus complex. Although this species was recorded from Baja California, MacNeill (1962: 95) has discussed the problems inherent in such a record. The three specimens collected by the mainland party show another of the 174 VOL. 41 Annals of Carnegie Museum problems — exact species determination in the exadeus complex is diffi- cult, if not altogether impossible at present. When I was at the British Museum in 1964 I examined the series of Epargyretis arranged by Evans and found that it was confused. The entire genus, and particularly the I exadeus complex, is impossible to identify with certainty using Evans’s keys ( 1952 ) . A careful and exhaustive revision of this genus is necessary before any certain identifications may be made. The males before me apparently represent two species: the one from 19 miles east of Concordia, Sinaloa, keys to sociis Hiibner, but the j genitalia are like exadeus Cramer. The one from 2 miles east of Con- ! cordia keys to spina Evans. The female appears to be of spina.

This specimen is similar to a long series from Yucatan and definitely is i referable to the nominate subspecies. SINALOA: 17 mi. east of Concordia, 1^ 1-xi. Chioides catilliis alhofasciata (Hewitson), 1867. 1 This species in its several subspecies is found throughout much of ; tropical America. The subspecies alhofasciata is recorded from Arizona , through Central America and into Colombia (Evans, 1952: 56). This species is not an inhabitant of the very wet tropical forests. It prefers drier, more open situations than do other “long-tails.” C. c. albofasckita is an avid flower visitor, showing definite preferences ; for zinnias in cultivated gardens, the “desert willow” (Chilopsis linearis), and the flowers of large Compositae in the arroyos. These butterflies are very pugnacious and will engage others in mock combat at any time. j| This species was taken both on the peninsula and in Sinaloa, but it is surprisingly absent from collections made in Sonora. 1 have never seen catillus as abundant as it was in Baja California Sur. The series from the peninsula differs from the mainland representatives in the char- acteristics described by MacNeil (1962: 95), but the differences are not ! of a magnitude to warrant description of the Baja California population as an entity distinct from the mainland alhofasciata.

The nominate subspecies is known from the entire continental Neo- tropics, and is common as far north as the southeastern United States.

These butterflies are avid flower visitors and show some pugnacity toward others of their own kind, but not to the same degree as does C. catilhis aJhofasciata.

There are also Antillean subspecies. SONORA: Hermosillo, 3 5 2 2 20-x.

Urbanus dorantes calafia ( Williams ) 1926. This subspecies was synonymized to nominate dorantes by Evans 1969 Miller: Mexican Hesperiidae 177 (1952:92), but he saw no peninsular specimens. The Baja California material is extremely distinct from mainland examples, particularly in the extensive olive-gray overscaling of the upper surface and the grayer under surface lacking the purplish sheen of nominate dorantes. A more detailed description of calafia is given by MacNeill (1962:97). These butterflies are avid flower visitors and are found almost any- where in the Cape region where there is green vegetation. During the morning and late afternoon these butterflies are seen in the open, but during the heat of the day they are active only in shady spots. On two occasions (Mesa Puerta Azul, 1-xi, and Boca de la Sierra, 24-xi) we encountered swarms of calafia during the hottest part of the day under trees, feeding at flowers and flying about. No specimens were seen in open sunlight except when they were flying from the shade of one tree to the shade of another. I observed a similar phenomenon with the mainland subspecies in Costa Rica during July and August, 1963. Inasmuch as high temperature, greater amount of incident light, and lower relative humidity all were conditions during the times that we observed these habits, it is impossible to determine which factor gov- erns the dorantes habit of seeking shade in midday. Perhaps all factors were in operation. None of the other skippers showed this disposition to escape the sun of the hot part of the day while remaining active. This was the skipper most often attracted to light on the peninsula, and it seems to be somewhat crepuscular, flying much later than most other skippers.

Urbanus simplicius (Stoll), 1790. This species has often been confused with the following one, but Tilden (1965) has given the characters for separating them. My ovm experience in Costa Rica indicated that simplicius is more character- istic of wetter environments than is procne. The present species is known from Mexico to Paraguay and Argentina. SINALOA: Mazatlan, 1^ 24-x; 19 mi. east of Concordia, 1$ 25-x. Urbanus procne (Plotz), 1881. This is the species generally referred to in the literature as sim- plicius from the United States (see Tilden, 1965). U. procne has the wider range of the two, being commonly found from southern Texas to Argentina, and it is more tolerant of dry conditions than is simplicius.

This '‘species” is in a confused state. Evans (1952: 128, pi. 21) de- scribes and presents five different genitalic configurations (poorly drawn ) of the valva with the comment, “The cuiller of the clasp varies considerably, as specified in the list of the B. M. material. But the dif- ferences seem to be individual rather than sub-specific.” In my opinion these differences are possibly specific, but the material available is not sufficient for definitive determinations. Significant results might be obtained by rearing through a few broods of these butterflies to see whether or not various configurations of the valva might occur in sib- lings. The material at hand from Sonora and Sinaloa either agrees with the figure of the genitalia given in Lindsey, Bell and Williams (1931: pi. 5, fig. 7, as coyote) or the valva is more pointed than in that figure. From Evans’s figures it is difficult to determine which of his groups are represented in our material, but probably groups D and E are. All the males have well-defined costal folds and apical hyaline spots; the female lacks the apical spots. SONORA: Hermosillo, 1 5 20-x.

These skippers are too worn to be compared profitably with mainland material and must be referred simply to valeriana at present. Evans (1952: 132) synonymizes the Dyar names mysie and uvydixa to valeriana, but MacNeill {in lift.) expresses some doubt as to the validity of Evans’s conclusion. Much more material is necessary before any decisions can be made on these names. BAJA CALFORNiA SUR: 4 mi. south of Arroyo Candelaria, 2$ 26-x. 180 Annals of Carnegie Museum VOL. 41 Figs, 1-3.

Two specimens of this subspecies were taken by the mainland party. They are distinct from the subspecies penimularis represented in the Cape region and described previously (Miller and MacNeill, 1969: 20-21). MacNeill (1962) mentions the possibility that the nominate subspecies may occur on the peninsula in the San Pedro Martir massif, Baja California Norte, but it has not been recorded to date.

Cogia calchas (Herrich-Schaffer), 1869. This species is one of the commonest in the Neotropics, but it is un- recorded from the peninsula.

This species is basically a member of the Sonoran desert fauna that has also penetrated Baja California. I can detect no difference between the peninsular and mainland populations. On the peninsula ceos was rather widely distributed, though never abundant. It generally sought the shadiest places available and seldom ventured far from them, at least during the hours of hot sunlight — I never saw it in the early morning or late afternoon. This species may be taken occasionally at water.

Soc., 5: 207 (type-locality: South Apache, Arizona). Antigonus evansi Bell, 1941. Ent. News, 52: 165; fig. 2 (type-locality: Babo- quivari Mts., Arizona). New synonomy. Figs. 4, 5 (Neotype d ), 6 (Neotype d genitalia). Edwards (1876: 207) described Hesperia zampa from a single ex- ample collected at “South Apache, Arizona” and retained it in his own collection. Later he sent this specimen and several others to Speyer for study (Brown, 1964). This shipment of butterflies was lost when the S. S. Pomerania went down in the English Channel, so it is appar- ent that the type of zampa was lost. Holland (1931: pi. 46, fig. 1) wrote the next chapter in the history of this name by figuring a specimen of S. pulverulenta (Eelder) as the “type” of zampa. As noted above, that specimen cannot be the authen- tic holotype of zampa, and was not even from the Edwards collection. It bears only the printed labels, “Arizona” and “Holland/Collection.” The Holland designation of the identity of zampa, however, was ac- cepted by many subsequent authors, notably Bell (1941: 164) and Evans (1953: 160). Both placed zampa in the synonymy of pulveru- lenta, justifiably if the specimen figured by Holland were the holotype of zampa. Bell (1941: 165) then described the second species of the genus occurring in North America as Antigonus evansi. Inasmuch as Bell and Evans have successfully separated these two species, I am reluctant to upset current nomenclature. I have discussed 184 Annals of Carnegie Museum VOL. 41 the status of the present species with several colleagues who have had extensive field experience in Arizona, and while all of us have seen hundreds of examples of this skipper, none of us has seen an unques- tionably authentic specimen of pulverulenta from that state. The few specimens that bear data other than the vague “Arizona” of earlier collectors are specimens taken by O. C. Poling that are labeled as from the Baboquivari Mountains. Poling, a professional collector, also col- lected extensively in the Davis Mountains, Texas (where pulverulenta occurs), and he was not overly careful with his data. So I suspect that at least some of the specimens he labeled as from Arizona were act- ually collected in Texas. Since I can find no authentic pulverulenta from Arizona, and since there are two specimens of “evansf from Arizona in the Edwards collection, I reluctantly designate one of the latter as the neotype of Hesperia zampa Edwards. This specimen bears labels as follows: first, a handwritten label, “Zampa cT/Edw. Ariz^.”; second, a printed label, “Edwards/Collection”; and third, a partly printed, partly handwritten label, “Neotype/Hesperia/zampa cT/W. H. EDWARDS/ designated by/Lee D. Miller, 1965.” The designation of this specimen has been done with the knowledge and encourage- ment of F. Martin Brown, who is engaged in a complete study of the Edwards types. The present species is well differentiated by Bell (1941: 164-166) and Evans (1953: 160), as evonsi, and these works should be consulted for a complete listing of the distinguishing characteristics. H. zampa is a desert or subdesert species, whereas pulverulenta occurs in less arid situations. We found the present species around watering places where it flew close to the ground, rarely visited flowers and lighted with the wings half open. These skippers were never particularly abundant.

Chiomara asychis georgina (Reakirt), 1868. This subspecies is the one represented in the southernmost United States, Mexico, and Central America. Evans (1953: 198) considers the Baja California material to be the same subspecies, as does MacNeill (1962: 100), but the peninsular specimens are consistently so different from mainland ones that the Weeks name pelagica (see below) is resur- rected for them.

The peninsular asychis are very different from the mainland repre- sentatives of this species, hence I am restoring the Weeks name pelagica to them. This subspecies most closely resembles Argentinian 1969 Miller: Mexican Hesperiidae 187 and Bolivian specimens of C. a. autander (Mabille) and bears little resemblance to the Mexican and Central American georgina. The differ- ences between georgina and pelagica are summarized in Table 2.

These butterflies were common almost everywhere on the peninsula where collecting was done. They do not visit flowers as avidly as do some of the other skippers and are more likely to be seen sunning themsleves on the tips of twigs with their wings outstretched. They are not particularly pugnacious, although they may on occasion attack almost anything that moves in their vicinity. The silhouette of these butterflies at rest is characteristic: the wings are held outstretched and the tips of the fore wings droop, giving the butterflies a convex appearance.

I am following Burns ( 1964 ) in attributing specific rank to funeralis, but most authors have considered it a subspecies of zarucco ( Lucas ) . This species is one of the most distinctive elements of the Sonoran desert fauna, and it is common in Baja California. In sharp contrast to most of the skippers, funeralis is to be found even in the very dry desert and in the brightest, hottest sunshine. It is very pugnacious and will engage in mock combat with almost anything that moves. It visits flowers frequently, showing a particular preference for the flowers of large yellow composites.

This subspecies was originally described from seven males collected in the Sierra de la Laguna (sometimes called Sierra de la Victoria). The genitalia of the two males taken by the Expedition look more like those of E. tristis tatius (Edwards) than those of the nominate sub- species. These two specimens were taken at the top of a windswept grassy hill at an elevation of 1270 meters. Oaks were plentiful nearby; these are postulated as the food plant by Burns (1964: 143). Since the type series was taken in May and the Expedition material was collected in November, this species is at least double-brooded in the Cape region.

Pyrgus philetas Edwards, 1881. I agree entirely with AlacNeill (1962: 101), who has reinstated philetas as a distinct species. Evans (1953: 222) had placed it as a sub- species of oileus. The present species is characteristic of the Sonoran and Chihuahuan desert and is found in the Cape region of Baja California. This skipper was found wherever there was water, though it was sel- dom abundant. It visits flowers and is particularly fond of those of the “desert willow.” Many other specimens were collected at mud puddles. P. philetas seems to be more widespread throughout the Cape region than albescens, but is not as common as that species in areas where both are present.

This subspecies is found infrequently from Texas and Arizona south to northern South America. A few specimens have been recorded previ- ously from the peninsula. This butterfly was never common and was taken only in several arroyos, although at Rancho Palmarito I saw a specimen or two that eluded me. Generally they were seen flying about in moderate shade or visiting low flowers. Unlike many of their relatives, these butterflies are very inconspicuous in the field. They are not combative, in contrast to most Mexican Heliopetes. The single female from south of Hermosillo is a striking aberration, differing from the ordinary female in the following particulars: the apical-submarginal row of white spots on the forewing, both above and below, is fused into a band that is connected to the discal white band, leaving a subtriangular black patch at the end of the forewing cell. The hind wing pattern is more or less normal, perhaps showing the white discal band a bit more developed.

This widespread tropical species is common in the Cape region of Baja California. 1969 Miller: Mexican Hesperiidae 191 Almost wherever there is water, natural or otherwise, laviana is abundant. These butterflies are avid flower visitors, preferring the flowers of low composites or leguminous plants. Otherwise the males will establish territories and attempt mock combat with other members of their species, but they are not as pugnacious as some of the “long- tails.” BAJA CALIFORNIA SUR: Rancho Rosarito, 2$ 1$ 23-x; Rancho El Novillo, 1$ 28-x; Rancho El Salto, 1$ 28-x; Rancho Palmarito, 2$ 27-x, 3^ 2$ 31-x, 2$ 4-xi; 21 ^ 4 $ 30-xi; Arroyo Hondo, near El Triimfo, 2 $ 24-x; Arroyo San Bartolo, 1 $ 12-xi; roadway 5 kilometers south of Sancho Buenavista, 1 $ 25-x; Miraflores, 1 $ 25-x; Boca de la Sierra, 1 $ 28-xi; Arroyo El Rincon, 1 $ 26-xi; Puerto Chi- leno, 1 $ 22-xi; Arroyo Candelaria, 1 $ 24-xi; 4 mi. south of Arroyo Candelaria, 2$ 24-xi.

The specimens listed below indicate that neamathla may actually be widely distributed throughout the Cape region, but it is apparently never common. With the abun- dance of Lerodea e. eufala (Edwards), however, it may have been overlooked by most collectors, since the two have rather similar habits.

This species and the next tend to replace one another, aurantiaca being far more abundant in the very arid regions, while minima is commoner in more humid environments. The present species is found in the southwestern United States and western Mexico, including the peninsula. C. aurantiaca was present in almost all areas of the peninsula visited by the Expedition, even in some of the driest arroyos. It does not visit flowers as readily as most of the skippers, but when it does, it prefers large yellow composites. Most of the time, however, it perches on a rock or a twig and waits for other butterflies, with whom it engages in mock combat.

This species, one of 'the most widespread in the Neotropics, penetrates the temperate regions to the north and south. It is common on the peninsula. H. phyleus is an avid flower visitor and almost any cultivated flower garden on the peninsula swarmed with these butterflies. Even when they are visiting flowers, these butterflies are always ready to engage another butterfly, a bird, or a butterfly collector in mock combat. They are easily captured when they are visiting blossoms, but otherwise these skippers are extremely wary.

Rindge (1948 : 309) recorded this skip- per from the peninsula, but the specimen was not available for study by MacNeill, who concluded (1962: 111) that tolteca was “a doubtful inhabitant” of the peninsula. Expedition personnel collected a dozen specimens in scattered localities in the Cape region, so this species is definitely present in the peninsula. All these specimens are worn, how- ever, and I have no specimens at hand of prenda, so I am unable to say which subspecies is represented by the Cape material. The specimens are generally a bit smaller than a series at hand from Piste, Yucatan, but there is no evidence of the grayish flush Evans (1955: 389) employs to characterize prenda. A. tolteca is not a common species, and its secretive habits would account for its being overlooked. It has a rapid flight and always re- mains close to the ground. It is not a pugnacious butterfly and is so unobtrusive that the collector must be especially observant to find specimens. The only flowers visited were those that grew close to the ground, such as coralvine.

Lerodea eufala eufala ( Edwards ) , 1869. This species is common throughout the American tropics and sub- tropics. It is abundant in Baja California Sur. These butterflies are avid flower visitors, preferring the cultivated varieties, and ‘‘desert willow,” coralvine, and large yellow composite blossoms. While these butterflies are combative, they are not as aggres- sive as H. phyleus or C. aurantiaca. Along with those two species eufala is one of the most abundant hesperiines on the peninsula.

It is closely related to L. arabus (Edwards) and is probably a subspecies of that species. There is a wide range of individual varia- tion in the specimens before me. All males have faintly delimited spots on the under surface of the hindwing in at least spaces Ms-Cui and Cui-Cu2. The spotting of the forewing, however, is far more variable: the cell spot is obsolescent in one of the males, a female from Baja California, and the female from Sinaloa, and the spots in general are variously developed, from prominent to almost obsolete, particularly those in spaces M.3"Cui and Cu2“2A. The variation is without regard to the configuration of the male genitalia. These butterflies are rather secretive skippers, little given to com- bativeness. They fly low, along the ground, and are attracted only to flowers that are a foot or less in height.

Since it has been recorded on the peninsula only from the environs of settle- ments where many ornamental cannas are grown year in ad year out, I am inclined to the opinion that ethlius is not native to Baja California, but rather was introduced there along with ornamental cannas. C. 198 Annals of Carnegie Museum VOL. 41 ethlius is, however, a well-known migrant (see Welling, 1964), and j it is possible that stray specimens have often reached Baja California ;i on their own. But not until the advent of cultivated cannas was there opportunity for this butterfly to establish colonies there. In any event, J this species is certainly not part of the natural peninsular fauna and is a recent arrival. i BAJA CALIFORNIA suR: La Paz, Hotel Giiaycura grounds, 15 22-x; Bahia de Palmas, 1 5 1 $ 16-xi, 1$ 29 20-xi.

It is known from California, most of the peninsula, and western coastal Mexico. These butterflies are always associated with coastal grasses and are i seldom found far from them. They are most active late in the afternoon, i when the males will take positions on grass stems and engage one i another in mock combat or will hover around females. The females : generally fly deep in the grass and are not so combative as the males. These skippers seldom visit flowers, but flowers were not abundant on the tidal flats where we observed these butterflies.

The cylindrodont rodents Craig C. Black ^ Section of Vertebrate Fossils, Carnegie Museum, Pittsburgh, Pennsylv Introduction In this, the fifth in a series of papers dealing witlr^^tebrates^^3m Badwater Creek, Wyoming, four species of cylindriodont rodents are described, one as a new species of Pseudocylindrodon. All specimens are from the Hendry Ranch Member of the Tepee Trail Formation (Tourtelot, 1957) and are of late Eocene or Uintan age. There are approximately one hundred and fifty isolated cylindrodont teeth in the Badwater collections at Carnegie Museum and at the University of Colorado Museum. The large majority of these specimens are from a single locality and appear to represent a single species, but because of the lack of associated dentition, it is possible that one or two speci- mens that represent different populations have been erroneously grouped together. Such an error, if it exists at all, is probably minor, however, as most of the specimens appear to fall quite readily into four discrete categories. Wood ( 1949 ) was the first to describe rodents from the late Eocene deposits along Badwater Creek, but he did not mention the presence of cylindrodonts in the fauna. However, he described and figured (1949, p. 559, fig. 11) an upper incisor which he referred to as cricetid indet. This incisor (Amherst College Museum 10004) is probably that of a cylindrodont rather than a cricetid and it appears to be referable to the new species of Fseudocylindrondon described below. The upper incisor of Pseudocylindrodon medius and of P. neglectus is oval in 1 Present address: Museum of Natural History, University of Kansas, Lawrence, Kansas 66044.

This is the condition described for the Amherst specimen referred to as a cricetid by Wood.

HORIZON AND LOCALITIES: Late Eocene, Wood and Rodent localities (Black and Dawson, 1966). DIAGNOSIS: Larger than Pseudocylindrodon medius and P. neglectus; cheek teeth not as high crowned as in P. medius and P. neglectus; M^-^ not as wide in 1969 Badwater Area: The Cylindrodont Rodents 203 relation to length as in other species of Pseudocylindrodon; only partially re- duced; hypoconid on P4-M3 not as enlarged and not pulled anteriorly as strongly as in P. medius and P. neglectus; Ms not greatly reduced. description: The deciduous is more triangular in occlusal outline than because of the enlarged buccal half of the anterior cingulum. The cusps are quite prominent on dP^ with the lophs poorly developed. The protoconule and metaconule are large and there is a small but distinct hypocone present. The permanent fourth premolar is as large as and and is similar in structure. P^ differs from the molars primarily in having a much shorter anterior cingulum which never passes internally more than halfway along the anterior face of the tooth. The posterior cingulum is also shorter than it is on and M^. No hypocone can be distinguished. On all the P^s in the sample the metaconules are large and the metaloph is incomplete, failing to reach the internal face of the protocone. In one specimen, CM 21303, there is a short, thin crest from the metaconule to the posterior cingulum. Mesostyles are prominent on all P^s. It is impossible to separate the first from the second upper molars when dealing with isolated teeth and the same is true for the lower first and second molars. The descriptions given here, therefore, apply to both. As in Oligocene cylindrodonts there is considerable variation in occlusal outline of M^-M^ which is dependent upon the stage of wear. Generally, are somewhat wider than long but the impres- sion is of a rather square occlusal outline. The internal border of the teeth is broad although there is no distinct hypocone. The union of the posterior cingulum with the protocone, however, is broad and the postero-internal corner of the tooth is consequently squared off. The anterior cingulum does not pass internally to the protocone, but covers only about two-thirds of the anterior face of the tooth. The mesostyles are usually large although in two specimens they are absent. In no instance is the buccal end of the central valley closed by the mesostyle or posterior slope of the paracone. There is considerable variation in the size of the metaconule which is occasionally almost undistinguishable within the metaloph, but more normally is quite large. The metaloph is either constricted at the protocone, fusing into the internal face well below the top of the cusp, or occasionally it is incomplete. In some specimens there is a short crest from the metaconule to the posterior cingulum (fig. 5) but more often the posterior valley is not bridged 1 Named for _Mrs. David Ruhala, formerly Miss Tobey Hall, vi^ho was a cheerful, able, and dedicated assistant with the Carnegie Museum field parties for three summers while we worked the Badwater area. 204 Annals of Carnegie Museum VOL. 41 by such a crest. The protoloph and metaloph diverge only slightly as they pass from the protocone to the buccal margin of the tooth. Figs. 1-21. Pseudo cylindrodon tobeyi, isolated teeth, all approximately x7. 1.

The protoloph and metaloph pass more or less directly across the tooth, not diverging as much as they do in the Oligocene species. A metaconule is still distinct on a few M^s (fig. 10) but more commonly it is absent. In several specimens there is a loph from the metaloph or metaconule running posteriorly to the posterior cingulum. One or two specimens are not at all reduced, resembling and to a remarkable degree (fig. 8). There is no posterior interdental wear facet on these teeth, however, indicating they are certainly third molars. The deciduous lower fourth premolar is quite long and narrow. The trigonid basin is wide and closed by the anterior cingulum and by a heavy posterior protoconid arm. The hypoconid is not enlarged or pulled forward as in the permanent P4, hence the buccal valley is wide. The hypolophid is strong and there is a wide valley between the hypolophid and posterolophid. There is considerable variation in the structure of P4 among the speci- mens here assigned to P. toheiji but the sample size is small and there is nothing in the sample of molars that would suggest that more than a single species is present. The amount of variation is displayed in two specimens, both taken from one quarry (figs. 12 and 13). P4 is generally as long as Mi and M2 but not as wide. The protoconid and metaconid are appressed, with only a small trigonid basin intervening. There is no trace of an anterior cingulum, so that the trigonid basin opens onto the anterior face of P4. The hypoconid is swollen and pulled anteriorly, resulting in a postero-internal direction for the buccal valley. The posterolophid is quite strong on all specimens and joins the entoconid just below the apex of that cusp, with the posterior valley thus closed off internally. The hypolophid is completely absent in one specimen (fig. 12), while it is a strong, complete crest uniting with the posterior end of the ectolophid in another ( fig. 13 ) . There are no stages of partial hypolophid development in the sample. When the hypolophid is present the posterior valley becomes isolated as a shallow basin after slight wear. The central, or talonid, basin opens internally as the entoconid and metaconid are separated by a deep cleft. The first and second lower molars are identical as far as can be deter- mined from a collection of isolated teeth. They are also quite uniform, showing little morphologic variation within the sample. Mi -Mo are rectangular in occlusal outline, with the anterior half of the teeth some- 206 Annals of Carnegie Museum VOL. 41 what narrower than the posterior. The trigonid basin is of moderate size in an unworn Mi or M2 and it is elosed both anteriorly and pos- teriorly. The hypolophid is always well-developed as is the posterolo- phid. The central valley is generally open internally with no metastylid present, while the posterior valley is closed internally after moderate wear. The hypoconid is swollen and pulled forward as in the Oligocene species. M3 resembles Mi and M2 in most details but differs from them in being more variable in size. Also, in some specimens of M3, the central valley is closed lingually and the posterior half of the tooth is somewhat reduced. This is effected through shortening of the hypolophid and posterolophid. One specimen, CM 21367, (fig. 21) is greatly reduced and approaches the condition seen in an unworn M3 of Cylindrodon. However, this tooth is much lower crowned than any M3 known of Cylindrodon. DISCUSSION: In view of its age, Pseiidocylindrodon tobeyi is amazingly similar to both P. medius and P. neglectus of the early Oligocene of Montana. There are a number of minor differences in dental morphology between the three, but P. tobeyi certainly bears out Burke’s conviction (1935, p. 12) that “the ancestor of Cylindrodon in the Upper Eocene had progressed beyond the stage represented in Pareuniys{?) troxelli m!’ and confirms his belief that Pareumys could not have been ancestral to Cylindrodon or Pseiidocylindrodon. By Uintan time there was at least one lineage whose cheek teeth were considerably higher crowned than in any species of Pareumys and this lineage could have been ancestral to Cylindrodon of the early Oligocene. Pseiidocylindrodon tobeyi differs from Pareumys not only in having considerably higher crowned cheek teeth but in a number of other features as well. The metaloph in Pareumys is incomplete (Wilson, 1940), whereas in Pseiidocylindrodon tobeyi it is usually complete. The metalophids on the lower molars are always complete and close the trigonid basin, while in Pareumys, the metalophids are progressively shortened from Mi to M3. The hypoconids of Pseiidocylindrodon are swollen and pulled anteriorly, while in Pareumys they are more as in My sops or various ischyromyids. Differences between Pseiidocylindrodon tobeyi and the Oligocene species of Pseiidocylindrodon are less striking and are usually ones of degree of development of structures rather than differing modes of development. There is less unilateral hypsodonty of P^-M^ in P. tobeyi 1969 Badwater Area: The Cylindrodont Rodents 207 than in P. medius and P. neglectus, and the Badwater species is some- what lower crowned. P. tobeyi is larger than the Oligocene species, and it is also larger than Cylindrodon. The valleys of the lower cheek teeth of P. tobeyi are not closed lingually as completely as they are in P. medius and P. neglectus. The hypoconid does not swing anteriorly as far nor is it as swollen in P. tobeyi as it is in P. tnedius and P. neglectus. Finally, the M3/3s of P. tobeyi are not as greatly reduced as those of the Oligocene species of Pseudocylindrodon. Through a slight reduction in size and a further emphasis on increase in crown height, P. tobeyi could have given rise to Cylindrodon, and with less increase in crown height it could have given rise to Pseudo- cylindrodon medius. If the Badwater species was not directly ancestral to the Oligocene cylindrodonts, it was certainly much closer to the Mysops-Cylindrodon lineage than was any species of Pareumys. Wilson (1940, p. 102, pi. 1, fig. 8) described and illustrated a single tooth from the Eocene Sespe deposits which he referred to as Pareu- mys(?) sp. This specimen was stated to differ from Pareumys in greater height of crown and completely enclosed posterior basin, and Wilson suggested the specimen might have affinities to the Oligocene genera Pseudocylindrodon and Cylindrodon. In addition to the characters men- tioned by Wilson, the hypoconid on this specimen is more swollen and is pulled further anteriorly than it is in the other California specimens of Pareumys described in the same paper.

The pro- j toloph and metaloph are complete with no distinct conules present. | These lophs are rather low, joining the protocone considerably below ‘ the top of that cusp. There is no hypocone or mesostyle. The anterior 1 cingulum is long, while the posterior cingulum is short and does not |] reach the buccal margin of the tooth. The tooth here considered to be an M^, CM 16896, has an unusual pattern unknown in any other cylindrodonts. Both the protoloph and the metaloph fail to reach the protocone. Instead they are both joined | to a short ridge that passes between them from the protocone. The protocone itself is hardly distinguishable as a cusp, rather the entire j lingual ridge of the tooth is thickened. The anterior and posterior cin- j gula are of equal length and neither reaches the buccal border of the tooth. Ml and M2 are rectangular in occlusal outline. They are somewhat lower crowned than the molars of P. toheyi, but are higher crowned than any Pareumys molars. The posterior protoconid arm is not fused ^ to the posterior slope of the metaconid and in some specimens it is directed posteriorly so that the trigonid basin is open to the rear (figs. 27 and 28). The hypolophid is strong in all specimens and the hypo- conulid is distinct. The central and posterior valleys are usually open j lingually, but they are partially closed in CM 15578. The hypoconids are not greatly swollen and there is only slight indication of the antero-buc- cal torsion of the hypocone seen in other species of Pseudocylindrodon. On M;i the posterior protoconid arm is very short, with the trigonid basin open posteriorly. The central valley is open, but the posterior valley is closed. The posterior half of the tooth is onh' slightly reduced through shortening of the posterior cingulum. 1969 Badwater Area: The Cylindrodont Rodents 209 DISCUSSION: It is possible that these nine specimens do not all repre- sent the same species. The seven lower teeth from four different local- ities all seem reasonably alike morphologically. The association of the and with the others is very questionable. Both these teeth, however, appear to be cylindrodont in morphology, and are of the proper size to be associated with the lower teeth. Nevertheless, no cylindrodont known possesses some of the features seen in the and M^, while the lower teeth are similar to lower molars known for other species of Pseudocylindrodon and Pareumys. The lower teeth appear to be intermediate between Pareumys and Pseudocylindrodon. They differ from Pareumys and resemble Pseudo- cylindrodon in: (1) being slightly higher crowned; (2) having some swelling and anterior torsion of the hypocone. They differ from Pseudo- cylindrodon and resemble Pareumys in having: (1) open central and posterior valleys; (2) short posterior protoconid arm with open trigonid basin. The material is too scrappy and distinctions still too hazy to warrant description of a new taxon. This taxon, if indeed these specimens repre- sent a single taxon, is more primitive than Pseudocylindrodon tobeyi and more advanced than the Badwater or any other species of Pareumys.

The two Badwater teeth are appreciably longer than wide, another Pareu- mys character in contrast to Pseudocylindrodon. The hypoconids of Pareumys sp. are not swollen nor do they show any anterior torsion as they do in the higher-crowned cylindrodonts. The posterolophids are low and the hypoconulids indistinct. The central and posterior valleys are broad and shallow. There is no metastylid. On CM 15990 the posterior protoconid arm passes into the metaconid slope isolating the trigonid basin from the talonid. These two teeth are slightly larger than either the first or second molars of Pareumys milleri or P. grangeri and the cusps and crests of the Badwater specimens are somewhat lower than in the Uinta species. In all other respects, however, they are quite close to CM 2938, the type of P. milleri. There is not sufficient material available from this Badwater popula- tion of Pareumys to allow specific determination. It is impossible to tell whether this population is consistently larger than P. milleri or merely a slightly larger variant of that species.

HORIZON AND LOCALITY: Late Eocenc, Wood locality (Black and Dawson, 1966). DESCRIPTION: All teeth are extremely small, much smaller than those known for any other cylindrodontid. On the metaloph is complete but there is a second crest from the metaconule to the posterior cin- gulum (fig. 33). The tooth is unilaterally hypsodont. The anterior cingulum is quite short, a character commonly found on P^s of other cylindrodonts. There is no mesostyle and there is no distinct hypocone. On the lower premolar there is almost no separation between the protoconid and metaconid. There is no hypolophid. The hypoconid is swollen and pulled slightly forward. The ectolophid does not reach the hypoconid, leaving the central basin of the tooth open into the buccal valley. The M3 has no posterior protoconid arm, so there is no trigonid basin. There is just an open slope from the anterior margin of 212 Annals of Carnegie Museum VOL. 41 the tooth into the talonid basin. There is a strong hypolophid (fig. 35) || on Ms and the hypoconid is enlarged and has a slight anterior torsion, i: These three teeth are tentatively referred to the Cylindrodontidae I because they display several characters common to that family and not ' found in other late Eocene rodent families: (1) unilateral hypsodonty of P^; (2) enlargement of hypoconid and its anterior direction on P4 I; and Ms; and (3) strong hypolophid on Ms. There is, of course, no cer- tainty that these three should be associated. However, because of their occurrence together at one locality, their uniform small size, and their similarity to other cylindrodonts, the association seems possible. The incomplete ectolophid on P4 and the complete absence of a : posterior protoconid arm on Ms are unique features unknown in other 1 cylindrodonts, although some third lower molars of Pareumys have the | posterior protoconid arm greatly reduced. The three teeth are relatively | higher crowned than those of Pareumys, however, and the hypoconid ji development differs from that in Pareumys. It is of interest that the three specimens are all from a single locality. | j This small species has not been found at any of the other localities 1 where large samples also have been collected using washing techniques, i It is hoped that future work will give us more information about this | : unique, tiny cylindrodont. !

The samples j of teeth from localities 5, 5A, 6, and Wood were recovered from con- J centrate resulting from the washing of at least four tons of matrix from ' each locality. The concentrate from each locality appears to be equally rich both in the number of total mammalian specimens and in the num- ber of mammalian taxa represented. There is still a small amount of unsorted concentrate from 5A and much larger amounts from 5, 6, and Wood. However, it is unlikely that sorting of this concentrate will 1969 Badwater Area: The Cylindrodont Rodents 213 change the distribution pattern of cylindrodont species at these local- ities, even though it will certainly alter the number of individuals and perhaps of the percentage of cylindrodonts in relation to the total fauna at each locality. The cylindrodont samples from localities 7 and Rodent were obtained through surface prospecting, and consequently may not reflect a true picture of species diversity at these two localities. I doubt this, however, as the general pattern for all localities seems to suggest an association of localities 5, 5A, 6, and 7 on the one hand, and Wood and Rodent on the other. Locality 7 is thus grouped with three localities from which large samples of matrix have been processed, and the Rodent locality is also grouped with a locality from which a large sample has been taken. Two cylindrodont species found at Badwater are known from such small samples that little faith could be placed on any generalizations based on them. Pareumys sp., the most primitive of the Badwater species, is known from only two specimens recovered a locality 6. The very small cylindrodont is known from only three specimens from the Wood locality. This species is certainly more advanced than the Pareumys species. The really striking distribution pattern is provided by Pseudocylin- drodon tobeyi, which is known to occur only at the Wood and Rodent localities, with only a half-dozen of the nearly one hundred teeth coming from the latter locality. With the concentrate resulting from the processing of at least twelve tons of mati'ix sorted, no specimens of P. tobeyi are known from localities 5, 5A, 6 or 7. That P. tobeyi is totally absent, or at the very least, exceedingly rare at these localities is, I believe, certain. At localities 5, 5A, 6, and 7, on the other hand, we find ?P seudocylindrodon sp. a somewhat more primitive species than P. tobeyi. ?P seudocylindrodon sp. is not common at these localities, however, as P. tobeyi is at the Wood locality. Whether this difference in faunal composition, which is seen in the cylindrodont rodents between these six localities, is due to age, ecology, or some other unforeseen sampling factor is unanswerable at present. It is interesting to note that Parectypodus lovei ( Sloan, 1966 ) is known from localities 5, 5A, and 6 from twenty specimens, but that only one specimen is known from the Wood locality. (Sloan, in his publication, did not mention the five specimens from 6 and the one from Wood. These have been recovered from the concentrate since 1966 ) . As more of the Badwater fauna is described, a clearer understanding of faunal 214 Annals of Carnegie Museum VOL. 41 differences should result. At present only eleven of the species listed by Black and Da\vson ( 1966 ) have been reviewed, and additional material is already known for five of the seven species discussed by Robinson (1968). This additional material in no way modifies the systematics Robinson presented but does alter the locality distribution for some taxa. On the basis of the cylindrodonts alone there is a slight suggestion ^ that the Wood and Rodent locality faunas are either somewhat younger i than those from 5, 5A, 6, and 7 or that there was an ecological difference reflected in the depositional environment.

Dawson Associate Curator of Vertebrate Fossils Carnegie Museum, Pittsburgh, Pennsylvania Introduction One of the best represented small mammals in upper Eocene localities along Badwater Creek is Mytonolagus. Specimens of this leporid have been found there at all localities of this level, not only isolated teeth but also maxillae, partial jaws, and a few postcranial parts. The genus Mytonolagus, the only described North American late Eocene leporid, was first reported from Uintan (Myton) and Duchesnean (Randlett) aged deposits in the Uinta Basin (Burke, 1934), where the species M. petersoni occurs. Later, Wood (1949) reported the genus from along Badwater Creek and named the new species M. wyomingensis on the basis of his Wyoming material. Thir- teen isolated teeth from one locality (Wood Locality of Black and Dawson, 1966: fig. 1; this and other localities shown there) constituted Wood’s sample. A later collection from a different upper Eocene local- ity along Badwater Creek (Gazin, 1956:8), probably Locality 5, 6, or 7, yielded a ro.axilla with P^-M^ that was referred to M. wyomingensis. Other reports of Mytonolagus since Burke’s original description are RusselFs (1965:8-9) reference of material from Swift Current Creek, Saskatchewan, to the Uinta Basin species, M. petersoni, and Black’s mention (1967:62) of the genus in the Shoddy Springs (Montana) local fauna. New material from Wood Locality adds to the record of M. wyom- ingensis from its type locality. Even more abundant, however, are specimens of Mytonolagus from Localities 5 and 6, located to the west of Wood Locality. These specimens differ from those from the type Issued September 25, 1970 215 ^THSb7v7^ UUT9 1970 ) 216 Annals of Carnegie Museum VOL. 41 locality in a number of characters, most of which indicate a more primitive level of development than in M. wyomingensis. Locality 7 also has yielded remains of Mytonolagus, although less abundant, in a level of development comparable to that at localities 5 and 6. Speci- mens from localities 5, 6, and 7 are all referred to here as Mytonolagus near M. petersoni. Finally, Rodent Locality has produced specimens referable to M. wyomingensis, although these show a few differences, possibly advances, from Wood Locality specimens.

EMENDED DIAGNOSIS: Species of Mytonolagus with buccal root on showing some sign of separation into two parts. Hypostria on P^-M^ more persistent than in M. petersoni. On M^'^ limit of enamel deposition reached buccally before tooth is worn out; buccal pattern eliminated at relatively earlier wear stage than in M. petersoni.

On P4-M3 postero- lophids present in early wear; lingual groove between trigonid and talonid persists nearly as far as buccal groove. DESCRIPTION: Only isolated teeth are known, but they provide a more complete sample and show a greater range of wear stages than in the sample available to Wood.

Following greater wear (fig. 2) this buccal lobe loses its separation from the central lobe, with a two-lobed tooth resulting. The single root bends posteriorly at its distal end. There is considerable variation among specimens of from Wood Locality, apparently both age and individual, in development of the anterior loph. In all relatively little-worn teeth, however, the anterior loph does not reach the buccal wall of the tooth, and two valleys, one buccal and one lingual to the central lobe, thus open onto the anterior face of the tooth (fig. 3). The central lobe does not contact the an- terior loph. Wood’s type specimen of M. wyomingensis, ACM 10022, is a tooth, broken anterobuccally, that he described as P^. On this tooth it appears that the central lobe contacts the anterior loph. This condi- tion is not duplicated in unbroken specimens of P^ from the type locality, but can be found on P^. It seems likely that Wood’s type speci- men is actually P^. Following wear, P^ becomes widened transversely (fig. 4), and in the most-worn known specimens has all pattern elimi- nated except the crescentic valley lingual to the central lobe. There is one buccal root, usually grooved medially and variable in showing one or two pulp cavities at its distal end. 218 Annals of Carnegie Museum VOL. 41 Only two specimens of are known from Rodent Locality, but these show some advance over those from the type locality in having a central lobe that bends more sharply anterobuccad, and two distinct pulp cavities in the buccal root. On the buccal root is grooved medially, and has two pulp cavities. The pattern in a moderately worn specimen (fig. 5) shows a shallow hypostria, central lobe that contacts the well-developed anteroloph, and posterior (Wood’s metacone), or posterior and anterior (Wood’s paracone), buccal cuspules. As with P^, the one known P^ from Rodent Locality is advanced beyond those from the type locality in the more pronounced anterobuccal swing of the central lobe and in the greater separation of the buccal root into two parts.

Following wear, the pattern becomes reduced to crescent and hypostria, and finally the buccal part of the hypostria forms an isolated lake. Deposition of the enamel is such that in well-worn specimens the tooth is past the enamel limit on the buccal side. The three known specimens of from Wood Locality show that the tooth is reduced and compressed anteroposterioiiy. The least-worn specimens (fig. 8) show the tooth to be composed primarily of the trigon. A deep buccal fold is present within the trigon and a very small posterior protrusion represents the talon. With wear, all pattern except a lingual groove, comparable to the hypostria on M^‘^, is present between trigon and talon. In the most worn stage known (fig. 9), the tooth is a cylinder, enamel is absent posterobuccally, and the only trace of pattern is a small enamel-lined lake, the remnant of the buccal end of the hypostria. No unworn specimens of P3 are known, but in the least- worn speci- mens available, trigonid and talonid are separate columns; the trigonid has an anterolingual fold, and the talonid is wider than the trigonid (fig. 10). Following greater wear the fold is lost, the trigonid becomes relatively wider, though still narrower than the talonid, and the two columns become joined by a medial bridge, resulting in lingual and buccal folds. Finally, the lingual fold loses its connection with the lingual wall and forms an isolated lake, which is worn away follow- ing still greater wear. Well developed posterolophids occur on P4-M2 in early stages of wear. The lingual groove between trigonid and talonid persists nearly as far down the tooth as does the buccal fold. None of the specimens shows a lingual bridge between the columns, although this might form in a very well-worn tooth. The talonid is slightly narrower trans- versely than the trigonid and both taper buccally. The only known M3 is from Rodent Locality. This tooth has separate trigonid and talonid, with the posterolophid indicated by a posterior expansion of the tooth and a posterobuccal groove. Only two specimens of deciduous teeth are known. DP^ (fig. 11) has three transversely oriented lobes, which join one another postero- buccally. The buccal lobe is very small and the lingual lobe forms most of the posterior wall. DP^ of M. wyomingensis (fig. 12) is less worn than that of M. petersoni, CM 11932, having the hypostria still con- 220 Annals of Carnegie Museum VOL. 41 nected to the lingual side of the tooth. The anterior arm of the central lobe joins the anterior lobe bucally at this stage of wear, whereas in the more worn dP^ of M. petersoni, anterior and central lobes are still independent bucally.

DISCUSSION: In his description and discussion of Mytonolagus wyom- ingensis, Wood (1949:561-565) considered some of this species’ charac- ters to be more primitive and some more advanced than in M. peter- soni, but he concluded that M. wyomingensis is ''a form close to, and perhaps even more primitive than, the Uinta Mytonolagus petersonir The characters considered primitive by Wood, which were taken from 1969 Badwater Area: The Leporid Mytonolagus 221 ACM 10022, interpreted by him as but here as were position of the metacone, and the poorly developed hypocone. The now-known specimens of both P^ and P^ show that these teeth in M. wyomingensis are actually more advanced than in M. petersoni. On P^ and P^ the hypostria, separting "protocone” and “hypocone” parts of the lingual lobe, is more persistent than in M. petersoni, and P^ has better devel- oped anterior buccal cuspules (paracone and metacone of Wood). It is not clear whether Wood considered the formation of two buccal roots on the premolars as a primitive or an advanced feature of M. wyomingensis, but it appears to be advanced. In the most prinimtive known late Eocene lagomorph, the Asian Lushilagus lohensis, both P® and P have a single buccal root (Li, 1965:30). This condition occurs also in Mytonolagus petersoni. The subdivision of the buccal root into two parts, which begins to occur in M. wyomingensis, is a stage of advance beyond M. petersoni and leads toward the condition of two buccal roots on P^""^ such as occurs in the early Oligocene leporids Palaeolagus temnodon and Megalagus hrachyodon. In these forms on P^ the anterior buccal root is fused to the large lingual root, and the two buccal roots of P^ are free. Loss of buccal roots on pre- molars and molars that occurred in the more progressive lines of leporids during the Oligocene was accompanied by increased hypos- odonty and atrophy of more buccal parts of the upper cheek teeth. In the molars also M. wyomingensis shows advance beyond M. petersoni, especially in longer persistence of the hypostria and earlier elimination of buccal parts of the molar pattern. The leporid from Badwater Lo- calities 5, 6, and 7, described below, seems to be a good intermediate between M. wyomingensis and the more primitive M. petersoni. Mytonolagus near M. petersoni Figures 13-27, Tables 2, 3 localities: 5 (70 teeth, 3 maxillae, 2 jaw fragments in CM), 5 A (52 teeth, 1 jaw fragment in CM; 21 teeth in UCM), 6 (37 teeth, 6 maxillae, 1 jaw in CM), 7 (11 teeth in CM); 5, 6, or 7, USNM 21090, left maxilla with P3M2. DESCRIPTION: This leporid is represented by more complete upper and lower jaw material than is M. petersoni from the Uinta Basin. The parts than can be compared show agreement between the two forms in most features. The zygoma protrudes laterally about in line with the anterior margin of P^, which is slightly more posterior than in Palaeolagus temnodon. There are two mental foramina on the jaw 222 Annals of Carnegie Museum VOL. 41 (fig. 13), the more posterior of which is in line with the talonid of P4, as in M. petersoni. The more anterior foramen is relatively far for- ward below the diastema, in an area not preserved in known speci- mens of M. petersoni. The anterior mental foramen is more posteriorly situated on the diastema in P. temnodon. The anterior border of the masseteric fossa reaches to below Ms, with a knob and fairly well- developed ridge forming the anteroventral border of the fossa. On the medial surface of the jaw the swelling over the shaft of the incisor terminates posteriorly in a line below the anterior of M2, about as in M. petersoni. Figs. 13-14.

Palaeolagus temnodon has a relatively more reduced M^. In the lower jaw M1.2 are subequal in M. petersoni and Mytonolagus near M. petersoni, or M2 may be slightly larger. Both these molars are larger than P4. In P. temnodon, P4-M0 are more nearly equal in size. 15 Figs. 15-16. Mytonolagus near M. petersoni, occlusal views of teeth in jaws, x 10. fig. 15: CM 14403, right P4-M2. fig. 16: CM 19770, right Mi-s. The groove of the upper incisor is slightly medial of center, and the medial portion protrudes farther anteriorly than the lateral. The first upper cheek tooth, P- (fig. 17), consists of three lobes, transversely oriented as in M. wyomingensis. Even in the most worn specimen available, three lobes are still present as they are in the very worn type specimen of M. petersoni, and it appears that the two-lobed 224 Annals of Carnegie Museum VOL. 41 shape found in worn of M. ivyomingensis would not occur here. The roots are fused into a wider posterior and narrower anterior part or may separate into two parts at the distal end. As in M. petersoni and M. wyomingensis, exhibits variation in transverse width of the anterior loph. The lingual groove is barely indicated, even in relatively unworn teeth, and thus is similar to that in M. petersoni, but less well developed than in M. wyomingensis. The single buccal root has one pulp cavity, as in M. petersoni. The lingual hypostria is only rudimentary on P^ (fig. 18), shallow even in relatively little-worn teeth. The central lobe remains distinct from the anterior lobe until well worn. The tooth is less well developed anterobuccally than in M. wyomingensis, has less buccad development of the anterior lobe, and less development of the antero-buccal cusp. The buccal root is grooved but has only a single pulp cavity. The central lobe of and posterobuccal part of that tooth are better developed than on M^. In relatively little worn examples of both teeth, the central lobe has a contact with the lingual shelf and a posterobuccal protiusion which is better developed and extends farther on than on M^. The hypostria curves strongly posterobuccad at this stage of wear. After greater wear the central lobe loses its con- nection to the lingual shelf and the buccal tip of the hypostria forms an isolated lake. These teeth differ from those of M. petersoni in two principal features. First, the hypostria extends closer to the enamel limit than in M. petersoni. Second, the central lobe in this Badwater form shows some advance: on MMt is more concave buccally and its posterior connection is oriented more posterobuccally than directly posteriorly, as in M. petersoni; on the central lobe has a stronger posterior protrusion than in M. petersoni. Even in very well worn teeth, traces of pattern are preserved buccal to the central lobe. These traces do not occur in M. wyomingensis in comparable stages of wear. Enamel persists on the buccal side of the molars even in very well worn stages in contrast to M. wyomingensis, in which the buccal enamel is absent in well worn teeth. It appears that considerable reduction has already affected (figs. 19-21), but the tooth is distinctly more robust and less reduced than in M. wyomingensis. When unworn, the trigon shows a strong V-shape with a rounded remnant of the central lobe in the buccal opening of the V. Posterior to this is the protrusion of the talon, developed lingually but not bucally. In the most worn specimen available there 1969 Badwater'Akea: The Leporid Mytonolagus 225 is a hypostria, lingually between trigon and talon, and an isolated lake. The only known, very worn of M. petersoni, CM 11937, is somewhat larger than most specimens of this tooth of Mytonolagus near M. petersoni.

The lower incisor, as in M. wyomingensis and M. petersoni, is rela- tively narrower transversely in its ventral part than is that of Palae- olagus temnodon. In the least- worn specimen of P3 (fig. 22) a small posterolophid is still indicated by posterolingual fold, and the trigonid has a well- 226 Annai.s of Carnegie Museum VOL. 41 developed anterolingual notch. The presence or absence of a connec- tion between trigonid and talonid is variable, some specimens having a connection near the lingual side, while in others, seemingly in com- parable stages of wear, trigonid and talonid remain separate. The trigonid and talonid are nearly equal in width ( fig. 23 ) , as opposed to a narrower trigonid in M. wyomingensis. There is never a deep lingual fold as in M. wyomingensis. In very well worn teeth (fig. 24) the pat- tern consists of a buccal fold and an isolated lake lingual to the fold, a remnant of the more lingual part of the trigonid-talonid fold. The only know Pss of M. petersoni are very worn, retaining only the buccal fold between trigonid and talonid. The pattern on Pt-M^ generally resembles that in M. wyomingensis, with a well-developed posterolophid present in early wear. These teeth are hypsodont but M2 shows toward its distal end a constriction of the rooted portion. The lingual groove between trigonid and talonid is more persistent relative to the buccal groove than in M. petersoni. Following wear the talonid extends an anterolingual process toward the trigonid, but in known specimens the columns do not join as they do in the very worn type of M. petersoni. Little-worn M3 has a two-cusped trigonid, two cusped talonid, and well-developed, cuspate, posterolophid. With wear the cusps are flattened, and trigonid and talonid join lingually. Next, trigonid and talonid join buccally also, first with an enamel-ringed lake between them that is finally worn away. In the most worn Ms available, the posteroexternal groove between talonid and posterolophid is also worn away. The tooth is relatively larger, especially anteroposteriorly, than that of M. wyomingensis. All deciduous teeth except dP^ are represented. Little worn dP^ (fig. 35) has a shallow hypostria and a long anterior lobe, which extends to the buccal wall anterior to the central lobe. The hypostria is re- moved with wear. DP^ has a hypostria that forms an isolated lake following wear. Its crescentric valley lingual to the central lobe con- nects to the buccal wall in earlier stages of wear but loses the connec- tion later. An isolated lake is buccal to the central lobe. Out of the four known dPss, none are unworn. The least worn shows that the tooth had three lobes anteroposteriorly and a protruding posterolophid. The two anterior lobes join first (fig. 26). In greatly worn specimens the three lobes are joined. As on dPs, the talonid of dP4 has a protruding postero- 1969 Badwater Area: The Leporid Mytonolagus 227 lophid. Following wear the two lobes of dP4 (fig. 27) become joined lingually by a bridge.

DISCUSSION: The leporid from localities 5, 6, and 7 differs from M. petersoni mainly in its relatively longer hypostria on the upper molars, longer lingual fold between trigonid and talonid in the lower molars, and in evidence of a more crescentic shape of the central lobe on It and M. petersoni differ from M. ivyomingensis in having a more persistent buccal lobe on P^, having on P^"^ a single root with little or no subdivision into two parts and less development of the hypostria, retaining into later wear stages the folds buccal to the central lobe and buccal enamel on and having less reduced M%. The differences 228 Annals of Carnegie Museum VOL. 41 between M. petersoni and Mytonolagus from localities 5, 6, and 7 suggest a more advanced level of development in the latter. These two forms seem more similar to one another than either is to M. wyom- ingensis, but differences of the Badwater form from the Uinta Basin species suggest that the former should be referred to as Mytonolagus near M. petersoni.

The more westerly localities (5, 6, and 7) have produced the most primitive, a form slightly more advanced than M. petersoni. The more advanced M. wyomingensis occurs in the more easterly Wood Locality, and it, or a slightly more advanced form, is repre- sented also at Rodent Locality. So far as known no M. wyomingensis is present in localities 5, 6, and 7, and no M. petersoni in Wood or Rodent localities. These forms, along with the Uinta Basin leporid M. petersoni, represent gradual stages of development within the late Eocene. In addition to the late Eocene occurrences of Mytonolagus in the Uinta Basin and Badwater Creek, the genus has been reported from the Shoddy Springs local fauna of southwestern Montana (Black, 1967:62) and from Swift Current Creek, Saskatchewan (Russell, 1965:8-9). The Shoddy Springs Mytonolagus is represented by only a few teeth, which are smaller than those of M. petersoni but more similar to it in occlusal pattern than to M. wyomingensis. The Swift Current Creek lagomorph was referred by Russell (1965:8-9) to M. petersoni. Comparisons with the Uinta Basin specimens show, however, that in the Saskatchewan form the hypostria on the upper molar of NMC 8653 extends closer to the enamel limit than in M. petersoni. It differs from both M. petersoni and M. wyomingensis in having on P4-M2 of ROM 1679 the trignonid shorter anteroposteriorly relative to the talonid, which is more rounded lingually and reaches less far linguad, and in having a relatively longer lingual groove between trigonid and talonid. No little-worn P3S are known for M. petersoni, but comparisons with P3 of Mytonolagus near M. petersoni and M. wyomingensis show that on P3 of the Saskatchewan form both the anterolingual fold and the more posterior lingual fold are situated more posteriorly than are the comparable folds in the specimens of Mytono- lagus. Perhaps the more posterior lingual fold in the Saskatchewan forms marks the posterolophid of P3. The Saskatchewan form is not yet known enough to serve as the basis for speculation. However, it is probably not referable to M. petersoni, and possibly not even to Mytonolagus. The characters of its lower cheek teeth are somewhat similar to those of some relatively primitive lagomorphs like Desmato- 230 Annals of Carnegie Museum VOL. 41 lagus vetustus of the Mongolian Oligocene. In Shamolagus medius of the Mongolian late Eocene the folds on P,; seem similar in position to those on P;^ of the Saskatchewan form. The Saskatchewan lagomorph suggests greater diversity in late Eocene North American lagomorphs than has been suspected, and although the evidence is not yet sufficient, it seems to have a few characters found in some of the Asian late Eocene lagomorphs and possibly in some later Tertiary North American lago- morphs that have been referred to as "'DesnuitolagusT The late Eocene lagomorphs of China and Mongolia (Burke, 1941; Li, 1965) form at least two groups, that of Lushilagtis and its relative Shamolagus, and that of Gobiolagus. Of these, the former group is the more generalized and probably led toward Desmatolagus of the Oligocene. Gobiolagus is specialized in its strongly developed unilateral hypsodonty and rela- tively small talonids, and seems to have persisted into the Oligocene. Mytonolagus cannot be tied closely to either of these groups and appears to be more advanced toward later North American leporids in the proportions of its cheek teeth. The Saskatchewan form is more advanced in the proportions of one tooth to another than are mem- bers of the Asian Lushilagus-Shamolagus-Desmatolagus group. How- ever, the Saskatchewan form shows a little greater resemblance to that group than does Mytonolagus. References Cited Black, C, C. 1967.

Beds containing fish scales and teeth were reported as early as I 1876 (Stevenson, 1876: 78, 326). P. E. Raymond (1910) noted the I presence of bone in the Ames limestone and underclay and in the I Birmingham shale. E. C. Case ( 1915) described some tetrapod remains I from Pitcairn, Allegheny County, and summarized earlier vertebrate I fossil finds from southwestern Pennsylvania. Moran (1952) and Romer I (1952) discussed all vertebrate fossil finds previous to 1952 from the Pennsylvanian of Allegheny County as well as from the Dunkard of I West Virginia and Ohio. Kent (1967) and Schweinfurth (1967) repeat- I edly mentioned the occurrence of fish remains in the fresh-water I limestones of southwestern Pennsylvania. Fossil fishes below the Cone- I maugh are known from two famous localities: Linton, Ohio (New- I berry, 1873, 1875), and Cannelton, Pennsylvania (Westoll, 1944), I within 70 miles of Pittsburgh, but are seriously in need of restudy. acknowledgments: I am grateful to Carla Hartz and Lee Ambrose, who have ably and enthusiastically illustrated this paper; W.

This work has been supported by a grant from the Pittsburgh Foundation to the Section of Vertebrate Fossils, Carnegie Museum. Geologic Setting The Ames marine horizon of the central Conemaugh group marks a change in depositional history in this area from alternating near-shore marine and fresh-water sediments of the lower Conemaugh, to the predominantly, if not exclusively, fresh-water beds of the upper Cone- maugh, Monongahela, and Dunkard groups. Fossils useful for correla- tion above the Ames limestone are plants, ostracods, and insect wings. Zonation of the Pennsylvanian-Permian section of western Pennsylvania is based chiefly upon plant successions (Darrah, 1934), coupled with classic applied stratigraphic principles. Little use has been made of the invertebrates, and no use of the vertebrates. The presence of cyclical deposits throughout the Pennsylvanian and Permian of southwestern Pennsylvania indicates repetition of varied ecological and depositional conditions. A typical cyclothem in the Pitts- burgh area consists of several elements. A clay zone, representing soil formation, contains scattered plant material. A carbonate zone which may contain a few teeth and denticles of Orthacanthus, and an occa- sional microsaur tooth, may occur in the clay. These carbonates thus seem to represent local flooding or standing-water conditions. Fresh- water limestone may be developed within the clay zone, usually locally. Overlying the clay is either coal or a trace of coal, with plant material only. The coal is usually succeeded by a jet-black, carbonaceous and pyritic shale, either massive or very thin-bedded, and of fresh-water origin. Massive shales may have occasional scattered fish material, while thin, evenly-bedded shales may contain many fish scales and occasional articulated vertebrates, as well as pieces of plant stem and leaf. This thin black-shale zone grades upward into gray, flaky shale, irregularly bedded, containing plants, insect wings, and conchostrac- ans, seemingly representative of very shallow-water, mudflat facies. Above this zone lies a thick zone of plant-containing, light-gray silts and interfingering sands, upon which another clay zone is developed. Fish remains occur, broadly speaking, in two different sedimentary types representing strikingly different ecologies. The most readily observable remains occur in the jet-black, carbonaceous siltstones and shales that frequently accompany coals or coal zones. Bones, scales. 1969 Fossil Fishes From Southwestern Pennsylvania 233 teeth, and spines of fish, filled with pyrite, are accompanied by copro- litic material and, much more rarely, by articulated specimens or portions of specimens. Fish scales occur irregularly throughout the black shales and may be locally concentrated. Tetrapod remains are rare to nonexistent. Fresh- water limestones may contain local concen- trations of fish and tetrapod remains, under somewhat specialized sets of depositional circumstances that are not well understood. Fossil vertebrate specimens, furthermore, are almost never found articulated in these limestones. While it is not unusual to find small numbers of fish teeth and scales in fresh-water limestones, only rarely are sufficient concentrations of material found to be of any paleontologic use. Stratigraphically useful invertebrate fossils are rare. But many hori- zons contain fossil-fish material, and it may be possible to correlate units on the basis of their vertebrate faunas when the latter are known well enough. This paper is a preliminary report on a few fresh-water fossil fish from one of these horizons, the Duquesne limestone. The following abbreviations are used throughout: AMNH, American Museum of Natural History; CM, Carnegie Museum; DL, Duquesne limestone; CMSL, Carnegie Museum Stratigraphic Locality, Section of Invertebrate Fossils; FMNH, Field Museum of Natural History. DUQUESNE CLAY AND LIMESTONES The Duquesne clay occurs between the top of the Grafton shales and the base of the Duquesne coal (Johnson, 1929). In places where the Grafton shales are cut out, the Duquesne clay lies directly on the Ames limestone (Johnson, 1929: 5). The clay averages about eight feet in thickness throughout Allegheny County and contains, in its upper portion, occasional well-preserved terrestrial plant fossils stand- ing erect (CMSL 366). A carbonate zone occurs near the center of this clay, generally poorly developed and unfossiliferous, but persistent. North of the bluffs of the Allegheny and Ohio rivers, the carbonate zone appears in three layers of fresh-water limestone. They are dark gray to black, weathering to tan on a fresh break, and have a peculiar, foul, swamp-like odor when crushed or in contact with acid (White, 1878). Broad slabs exposed along McKnight Road, Ross Township, show many unrecognizable fragments of bone on their surfaces. To my knowledge, the Duquesne limestones occur in only one area south of the Allegheny River, namely the west end of Mount Washing- 234 Annals of Carnegie Museum VOL. 41 River, opposite Herr’s Island; 3. Riverview Park, 100 feet below Allegheny Observatory, ton, within the city of Pittsburgh. In this area, limestones 2, 4, and 6 outcrop for almost a mile along the bluffs of the Monongahela River, and again for a short distance west of the south end of the Fort Pitt Tunnels (fig. 1). Limestone 2a, 3, and 5, however, seem to occur only for about 200 yards of outcrop east of the north portal of the Fort Pitt Tunnels. They represent small bays that extended southward from extensive marly lakes. The Duquesne limestones from this area have produced an extremely rich and varied vertebrate microfauna, part of which is described here, as well as many fragments of larger vertebrates. 1969 Fossil Fishes From Southwestern Pennsylvania 235 The invertebrate fauna is limited to ostracods, conchostracans, and Spirorbis. The outcrop of these limestones at the north portal of the Fort Pitt Tunnels is in a tall, slowly sagging, slump block. Significant quantities of varied vertebrate material occur within and between the two top limestone units and in the lowest limestone. The sedimentary character of these units is worthy of more study than presently can be devoted to them. The upper unit (DL 2) grades into gray calcareous siltstone above as well at the east end of the outcrop. Scattered fish scales and teeth are found near the base of this siltstone. The limestone is distinctly conglomeratic, composed of dark and light lime pebbles and plates of siltstone in a calcareous and silt ground mass. The particle sizes are clearly larger toward the base of the unit, and most of the bone occurs in the lower inch of this bed. Bone occurs in all components of the rock unit, but is most common in the calcareous silt ground mass. There are associations of bony elements that indicate parts of individuals, but no articulated components. Non-carbonized but finely comminuted plant material is present throughout the unit. Fragmented tetrapod remains are common. A very thin shale break provides an irregular plane of separation between DL 2 and DL 2a. This break, between ^3 2 inch and % inch thick, has yielded scales, teeth, a partially articulated fish, and parts of a reptile. Duquesne limestone 2a varies as greatly in composition as it does in thickness. In the thinnest parts, it is composed of thin plates of very light and very dark shale with calcareous cement. This unfossiliferous sediment may grade into either of two other types within a few inches. The more common type is a dark-brown limestone interrupted by frequent and seemingly random seams of calcareous silt. Small fossils are more prevalent in the silty fractions than in the limestones, while macrofossils are found in the limestones or crossing both silty and lime- stone portions. The remaining lithologic type is a massive, very dense, very black limestone with finely disseminated crystalline calcite. Macro- fossils are lacking but fragmented microvertebrate fossils are common. Tetrapod material is almost totally absent in the lower of the two lime- stone units, and is limited to microsaur bones. Duquesne limestone 6, averaging almost one foot in thickness, is a massive unit high in clay, locally high in iron compounds, and contain- ing some gypsum crystals as well as an irregular mesh of calcite tubules, possibly from burrow fillings. Orthacanthus and Xenacanthus teeth, 236 Annals of Carnegie Museum VOL. 41 2a 1 r 1969 Fossil Fishes From Southwestern Pennsylvania 237 paleoniscoid scales, and small tetrapod bones are irregularly distributed throughout and may be locally concentrated near the base of the unit. Lungfish remains are present but rare. Transport of bone seems to have been significant in DL 2, but mini- mal in DL 2a and DL 6. Reworking of the unconsolidated substrate by burrowing organisms may have been the most important factor in disarticulating specimens in these units. Deformation of bones prior to lithification can be seen in certain specimens from all fossiliferous limestone units. Small microsaurian vertebrae are generally skewed to one side. A large portion of an Orthacanthus spine was bent to the point of shattering individual longitudinal bony spicules. A large Sagenodus cf. S. periprion operculum was crushed from above, fragmented, and spread out to occupy almost twice its intact area. These examples, however, are exceptions, for most bones, large and small, show no trace of the effects of fossilization. The distinctly fresh-water nature of the deposits is indicated by the presence of Orthacanthus sp., Sagenodus periprion, and another dip- noan, as well as by the several tetrapod remains. The assignment of the name Duquesne limestone to these beds (Johnson, 1929: 60) recognizes their proximity to the overlying Duquesne coal and/or black shale. This stratigraphic proximity is de- ceiving, for the limestones occur in the midst of a clay representing a soil zone, a gap in deposition of unknown duration. At least one layer of erect, fossil land plants occurs between the definitive Duquesne coal horizon and the underlying limestone-coal sequence (fig. 2), The six- inch coal overlying the limestone sequence at the Fort Pitt Tunnels is not the Duquesne coal of Johnson (1929), which is represented by a trace at the base of the Birmingham shales at this place.

The time elapsed, however, in deposition of each of the two principal fossil-bearing lime- stones (DL 2 and DL 2a), is geologically very short. Neither bed shows any interruption or change in the nature of deposition vertically. Parti- cle-size distribution suggests that DL 2 is a single, graded bed. Larger pieces of tetrapod bone are abraded and occur at the base of the bed, i suggesting transportation of these chunks along with the plates of | hardened silt. The small bones of fish and microsaurs are, for the most ; part, unworn and uninjured in spite of their great fragility. The remains j of these aquatic vertebrates, found in the lime-silt ground mass, prob- ably represent an in situ fauna. The peculiarities of this bed can be j compared to a dried swamp bed flooded with silt-laden water. i DL 2a contained a major portion of the skull of one individual of ; Sagenodus cf. S. periprion (CM 19127). The bones were disarticulated * but closely associated, and in some cases extended from the top to the bottom of the stratum. The bed itself is quite limited in area and ; probably represents the product of a single season of deposition of . calcium carbonate in a shallow and algal-filled body of water . Certain vertebrate elements in the fauna of the Duquesne limestones lend themselves readily to identification; others, such as the isolated paleoniscoid scales, cannot presently be treated.

Xenacanthus cornpressus Hotton, 1952. description: Several hundred teeth, ranging in height from /2 mm. to 3 cm., plus parts of two fin spines, have been found within the limited volume (5 cubic feet) of rock dissolved from DL 2a. These teeth, while varying in size and pro- portions of the two main cusps, are perfectly uniform in characteristics. Each tooth has two large, blade-like serrated cusps, and a tiny central, generally unserrated, cusp upon a prominent rounded base. The basal surface of the tooth is cupped for attachment to the jaw, and a prominent boss is present lingual to the cusps on the denticulated surface. The two major cusps are almost of equal size in teeth that seem to be from near the symphysis, while on other teeth there is progressive proportional difference in the height of the two cusps. This feature, together with strong angling of the smaller cus, seems to be indicative of teeth located far back along the jaws. The spines (fig. 3) rae rounded in cross-section, thick, composed of longitudinal bony fibers reflected externally as fine striae, and bear a double row of small, sharply downcurved denticles proximally along a cupped rear margin. No complete spines have been found. DISCUSSION: Hotton (1952) suggested that only one genus {Xenacan- thus) of North American pleuracanth shark is known. Gluckman ( 1964: 211-212) reproduced the superb illustrations of von Fritsch (1889). These illustrations (von Fritsch, 1889, figs. 173-175) clearly indicate that the teeth named Diplodus (Agassiz, 1843) are associated with the spine named Orthacanthus (Agassiz, 1843, pi. 45, figs. 7-9), while the spine named Pleuracanthus (Agassiz, 1843, pi. 45, figs. 4-6), which is a senior synonym for Xenacanthus (Byrich, 1848), is associated with distinctly different teeth built upon the same general plan as those ol Orthacanthus ( Diplodus ) . Almost all reported North American pleuracanth teeth are of the Diplodus type, corresponding to the genus Arthacanthus. North Amer- ican spines of the genus Xenacanthus have been uniformly assigned 240 Annals of Carnegie Museum VOL. 41 Figs. 3-4. Fig. 3. Orthacanthus sp. Fragment of spine. CM 19131. Unit is 1 cm.

True Orthacanthus spines have been assigned incorrectly to the “genus” Acondylacanthus (Romer, 1952: 51). North American Xenacanthus teeth are rarely reported and tend to be overlooked prineipally because of their small size. In DL 2a, two robust spines of Orthacanthus accompany many teeth of comparable size. Orthacanthus teeth are also known from DL 2, 3, and 6. Genus Xenacanthus (Beyrich, 1848) Pleuracanthus Agassiz, 1843. Orthacanthus Newberry, 1873. 1969 Fossil Fishes From Southwestern Pennsylvania 241 Xenacanthus sp. Figure 4 One almost complete spine, plus a fragment of a second spine of this genus, is known from DL 2a. Teeth associated with spines of this size and delicacy have not been found in the same bed. However, Xenacan- thus teeth have been retrieved from DL 6 and are quite common in the Dunkard series of southwestern Pennsylvania. The spine (fig. 4) is quite thin, evenly tapered to the tip, and bears a row of depressed, recurved denticles on each side nearly throughout its length. The spine is nearly oval in cross section distally where the denticle rows are borne midlaterally, and is more highly arched proxi- mally along its presumed dorsal surface than its somewhat flattened ventral surface. The denticle rows are ventrolaterally placed near the proximal end. The teeth of Duquesne limestone Xenacanthus are diminutive, and differ strikingly from those of Orthacanthus. The two major cusps are subequal in size, approximately twice the length of the central cusp, thin, and circular in cross-section throughout their length. The two major cusps each bear six to eight thin vertical ridges along their distal halves from Orthacanthus in lacking a prominent labial process. The lingual “button’' is quite variable in development. Little angular devia- tion of the cusps from each other is present. There is no difficulty in distinguishing the teeth of Xenacanthus from teeth in the same size range of Orthacanthus. The spine of Xenacanthus arcuatus ( Newberry, 1873, pi. 40, fig. 4) from Linton, Ohio, Upper Allegheny series, differs from the Duquesne specimen in having a concave ventral face. No differences in spine shape are known between Conemaugh and Dunk- ard Xenacanthus ( to be reported on at a later date ) . It is not presently possible to make species assignments based on the small samples available.

HORIZON AND LOCALITY: Duqiicsne limestone 2a, Conemaugh, Pennsylvanian, 200 feet east of north portal, Fort Pitt Tunnels; Pittsburgh, Allegheny County. TYPE SPECIMEN; CM 19134, distal portion of a dorsal spine, Duquesne lime- stone 2a. REFERRED SPECIMENS: CM 19136, dermal denticles; CM 19135, teeth, from the Duquesne Limestone. A considerably broader spine fragment, equally severely compressed but showing more rapid tapering and no left-right alternation of denticle direction, comes from the Mason shale at Sample, Allegheny County. This spine (CM 21565) is regarded as a pectoral spine of the same "species” of hybodont shark. DISCUSSION: The teeth originally referred to Agassizodus variabilis by Romer ( 1952 ) were, in fact, not related to the marine Pennsylvanian fish bearing the original name. The teeth and spine fragments men- tioned by Romer are those of a fresh-water fish, and lack the broad, rounded cusps and the characteristic bradyodont structure of typical Agassizodus teeth. Order Dipnoi Family Ctenodontidae Woodward, 1891 Genus Sagenodus Owen, 1867 Sagenodiis cf. S. periprion Figures 6-9 Sagenodus cf. S. periprion have previously been described from the uppermost Conemaugh and the Greene of this region by Romer (1952: 52 ) . Remains from DL 2a consist of two opercula, two tabulars, a par- ietal, parasphenoid, numerous cheek and snout bones, ribs, and right pterygoid and vomerine tooth plates, all pertaining to one individual (CM 19127). This specimen has an associated vomerine tooth (fig. 6), the first such tooth reported for this genus. The forms of the cranial bones are apparently unchanged from the upper Conemaugh through the Dunkard and are relatively undis- tinguishable from the Texas Permian Sagenodus periprion (Romer, 1952: 54). The vomerine tooth ( fig. 6 ) is remarkable in its similarity to the form illustrated in figure 9 from the Duquesne horizon. Differences between these vomerine teeth are almost exclusively a reflection of the differ- ences in size of the forms. The similarity between these teeth is in 244 Annals of Carnegie Museum VOL. 41 Fig. 6. Sagenodus cf. S. peripron. CM 19127. Left vomerine tooth. A. Anterior view. B. Ventral view.

The tiny vomerine teeth pro- 246 Annals of Carnegie Museum VOL. 41 vided the first indication that a series of very tiny Sagenodus were preserved in the Duquesne limestone. This was confirmed only after a number of intermediate-size specimens were found in Monongahela- and Dunkard-group rocks. The latter specimens are currently under study. EARLY GROWTH: The Duqucsnc limestone Sagenodus provide an in- sight into the ontogeny of the jaws of this form. The most immature specimen, CM 19465, bears four rows of teeth on a flat, simple, bony plate. The four rows contain five, five, five, and three, teeth respective- ly, beginning with the most anterior row, which measures 86 mm. in length. Each tooth in each row is almost double the size of the tooth mesial to it. In CM 19471, the first row of teeth is missing, but the specimen bears a ventral ridge of bone that presumably lay mesial to Meckel’s carti- lage. The tooth rows show some fusion with growth of the individual teeth, so although there are five, four, and one, cusps respectively, the innermost cusps have been almost completely incorporated into the bases of the cusps next lateral. CM 19467, which shows a well-developed ventral ridge, also bears a first cusp-row of 1 mm. length. It has four rows, bearing three, two, two, and two, cusps respectively. All traces of the tiniest mesial teeth have vanished, while the remaining teeth in individual rows have grown into hefty, wellrounded cusps united at the base. The most anterior tooth row maintains a sharply bladed series of cusps. In all three speci- mens where the first tooth row measures more than 1 mm., or where the spenial bone is well-developed vertically, there are four tooth rows, with a maximum of three cusps in each row. CM 19468 (fig. 7) is the largest of the small Duquesne limestone Sagenodus, and the only specimen with five tooth rows. Evidence from Dunkard group specimens indicates that two additional cusps are added to each row before additional tooth rows are added to the splenial element. One right palatal element is known that corresponds in size range with these splenials ( CM 19469; fig. 7B ) . It is a broad, rounded element in a poor state of preservation which bears teeth or tooth bases indicat- ing the presence of six rows. The most anterior row is compressed and blade-like, while teeth in succeeding rows decrease in compression, in tooth size, and in basal proximity. The superficial glossy layer of the teeth seems to extend at least across the anterior two valleys between tooth ridges. The remarkable thinness of tooth walls, dramatically 1969 Fossil Fishes From Southwestern Pennsylvania 247 A Fig. 8. Sagenodus cf. S. periprion. CM 19468. Right splenial. A. Dorsal view. B. Labial view. Unit is 1 mm. illlustrated in this specimen, corresponds to the condition in several of the splenials. 248 Annals of Carnegie Museum VOL. 41 The blade-like anterior ridge of the palate and splenial evidently were piercing and chopping ridges. The large, rounded, and yet thin- walled teeth of the posterior ridges seem incapable of masticating anything firmer than soft plant tissue or soft-bodied invertebrates. A generally vertical action of the splenial-dental ridges between those of the palate seems to be the only possible way of masticating. The vomerine teeth assigned to this group ( fig. 9 ) have been placed here on the basis of two observations. The first is that they closely resemble the vomerine tooth of Sagenodus cf. S. periprion (fig, 6), to which the tooth rows on the jaws also bear some resemblance. The second is the assignment of vomerines illustrated by Berman ( 1968 ) to Gnathorhiza, which, if correct, strongly suggests that vomerines such as that in figure 12 belong with a genus more closely related to Gnathorhiza. Vomerine teeth of this size generally lack strong, bony bases. The bases, where seen, consist of highly spongy bone, spicular in construc- Fig. 9. Sagenodus cf. S. periprion. CM 19431.

The teeth themselves vary only in the degree of development of secondary cusps, which are not constant in number, proportion, or size. Few cusps, gradually increas- ing in size away from the midline, plus a slight anterior convexity, describe this form. Only two features distinguish this vomerine from that of large Sagenodus: its minuscule size and a lack of evident wear on the sides of the more mesial cusps. At the growth stages represented by the small Sagenodus specimens, there is no evident tooth wear. Addition of tooth rows and cusps with age is indicated in the Duquesne limestone Sagenodus where numbers of cusps per row is decreased by the incorporation of the smallest teeth into the bases of adjacent ones. Growth of individual teeth seems in- dicated, not only by this observation but by the tendency of larger splenials to have the teeth united at their bases, producing rows of cusps. The small specimens of Sagenodus provides a remarkable insight into the ontogeny of this form.

DISCUSSION: The jaws of small individuals of this species were very common in DL 2a, and were present in DL 2. One fragmented jaw was found in DL 6. Preservation was generally excellent; very few frag- mentary jaws were found. Size variation is between 1 mm. total lower- Fig. 11. Monongahela stenodonta. CM 19450, Type. Right pterygoid. A. Ventral view. B. Lateral view. Unit is 1 mm. 252 Annals of Carnegie Museum VOL. 41 jaw length and 9 mm. total jaw length. One pterygoid (CM 19455) shows growth and wear indicative of a specimen much older than the others. Most of the remains seem to represent young specimens, pos- sibly young-of-the-year. The pterygoid plates (fig. 11) show an interesting pattern of growth of the various ridges, which sheds light on changes in feeding during the life of the fish. The three anterior-cusp ridges are extremely sharp- edged in the small specimens with indivdual cusps quite discrete although not isolated from each other. The number of cusps per tooth- ridge stays constant through growth of the animal until all cusps are obliterated by wear ( fig. 13 ) . The fourth cusp row consists of one rela- tivley rounded cusp in the smallest individuals. Cusps are added with growth until the adult condition of the tooth plate is reached. At this point, the posterior ridge is of significant size, may contain up to seven cusps, and addition of cusp ceases. The three anterior ridges of the pterygoid are discrete in the young and meet at an apical cusp con- tributed by the central ridge. The posterior ridge is subsidiary to the ridge next anterior, originating on the side of that ridge (fig. 11). Growth of the ridges results in early union of the first three ridges at the apex, and considerably later in the incorporation of the fourth ridge. There is little wear in juvenile Monongahela pterygoids. Slight wear facets are developed only at the tips of the cusps, and extremely sharp edges are maintained in valleys and all sides. There is no indication of shearing of upper against lower jaw and no means of crushing food items. The mode of feeding is almost certainly that of an active predator with teeth designed to pierce and hold prey. C Fig. 12. Occlusal pattern in Monongahela. Solid lines represent pterygoid tooth ridges, dashed lines represent splenial tooth ridges. Ridges A,B,C, and D (ptery- goid only) labelled from anterior to posterior. 1969 Fossil Fishes From Southwestern Pennsylvania 253 With the achievement of a subadult size, as evidenced by growth of the fourth pterygoid ridge, aspects of wear become evident. Cusps gradually are obliterated by growth, from within and by abrasion, to form unified ridges. Ridges a and c, (see fig. 12 for key) united at the apex, are separated from b by a valley (fig. 13) produced by wear of the mandibular element, and a notch tends to be worn into ridge c by the mandible, generally lateral to the junction of c and d. The sub- adult shows a plate with one sharp, arcuate mesial ridge, composed of ridge a, the mesial part of c, and ridge d, plus two converging ridges separated from it, ridge b, and the lateral part of ridge c. Upon occa- sion, a specimen may be found where ridge c is notched mesial to its juncture with ridge d ( CM 19455 ) . The change in ridge shape and relationship occurs when the jaw is relatively large. Therefore it is postulated that the change occurs at a subadult stage. The change results in a style of feeding better adapted to cutting and chopping. Both animal and vegetable material could be obtained and chewed with this mechanism. The vomerine teeth attributed to this species (fig. 14) are rarely Fig. 13. Monongahela stenondonta. CM 19455. Right pterygoid. Ventral view.

They are blade-like, slightly convex anteriorly, I and grow by addition of successively larger cusps laterally. Newer vomerine cusps are slightly serrated along their mesial edges. The older I cusps show wear only on the mesial sides of their tips. As the vomerine i teeth are not opposed by any known toothed elements, it is inferred that wear was produced by the action of tooth against prey, which | suggests prey with a resistant external layer. The ostracods found in | the same deposits would be within the size-range of prey for most of the Monongahela specimens represented. The mandibular, or splenial, elements of Monongahela (fig. 10) do not differ noticeably from those of the Permian genus Gnathorhiza (Berman, 1968, fig. 2), except in size. The smallest specimen found, jj CM 19460, shows that: the anterior ridge a includes the apical cusp, j ridge b (see Fig. 12 for key) originates from the cusp next posterior |j to the apex, and ridge c includes only the remainder of the cusps on a | 1969 Fossil Fishes From Southwestern Pennsylvania 255 line from the apical cusp. The separation between ridges is lost very early. The range of angles found between ridges of the mandible is much greater than those of the relatively unvarying pterygoid. Bilateral variation is strong in CM 19485. The degree of latitude in lower jaw angles virtually prohibits accurate shearing action of the upper against the lower jaw and reinforces the belief that the feeding was accom- plished by chopping and piercing. In the young, cusps served to hold, pierce, and cut prey, while older individuals lost the need for cusps, either as a result of change in the predator-prey size relationship or a change in diet. The presence of single-bladed splenial elements in populations of Permian Gnathorhiza has been noted by Berman ( 1968 ) . Single-bladed splenial elements comprise 19.5 percent of the total number of Mon- ongahela lower jaws, and comprise a minimum of 16.1 percent of in- dividuals sampled in this study. The size-range of single-bladed splen- ials is great. CM 19464 (fig. 14) is the largest splenial of any sort found. These peculiar elements differ from normal Monongahela splenials in few ways. Most important, the transverse and posterior tooth blades are not present. The anterior blade is proportionally equal, in length, to the same element of a normal splenial. Shearing wear along the posteromesial half of the blade is evident (fig. 15) in all but the small- est specimens, as Berman (1968, fig. 2D) has illustrated for Gnathor- hiza. No other acute differences are known and no palates that match this lower jaw have been found. Several specimens give some insight into a developmental peculiarity of high frequency and surprisingly great duration. CM 19461, a very small single-bladed splenial, displays one cusp oriented at an angle equivalent to the transverse blade, and one cusp oriented at an angle equivalent to the posterior blade. These two cusps are quite small, and are at the posterior end of the large anterior blade. CM 19464 bears one excedingly small, rounded cusp on its posterolateral edge. CM 19463 bears a slight posterolateral ridge. CM 19444 and CM 19476 each display two rudimentary cusps of the transverse ridge, and CM 19481 displays a rudimentary transverse ridge. The single-bladed splenial is evidently produced through a reduction in the number of teeth in the posterior two ridges coupled with a lack of growth or exceedingly limited growth of the teeth that were present. 256 Annals of Carnegie Museum VOL. 41 Fig. 15. Monongaliela stenodonta. CM 19464, Right splenial, single bladed. Lin- gual view. Unit is 1 mm. 1969 Fossil Fishes From Southwestern Pennsylvania 257 The anterior ridge is normal in shape, size, and position, but the splenial lacks a prominent “heel” to stop jaw travel by contact with the “heel” of the upper jaw. An abnormal, though functional, shearing action can thus take place between the anterior ridges of upper and lower jaws. No palate has been found that would correspond to a single-bladed splenial in form or function, either in the Duquesne limestone or in the Permian Lenders formation ( Berman, 1968 ) . Berman has inferred that this type of splenial is simply an abberant lower jaw. When a specific change in dentittion of this magnitude, reflecting a relatively major change in jaw function and almost certainly in diet, can be demon- strated in high proportion over a considerable span of time and space, it is obviously an important biologic and ecologic factor. As the single- bladed splenial seems to arise through a developmental abnormality, it seems unwise to grant it separate taxonomic status at present. Conclusions Monongahela is clearly related to the Permian Gmthorhiza (fig. 16), differing chiefly in the interrelationships of the pterygoid tooth rows. Derivation of the Gnathorhiza palate may have been accomplished by a mesial shift in the point of origin of the most posterior tooth row, plus a spreading of the space between rows. Detailed treatment of this problem will appear in a later paper on some lower Dunkard Monongahela. The Monogahela-Gnathorhiza group shows definite similarities to the very young Sagenodus described above. The blade-like anterior tooth row, and the tendency towards a blade-like second row in Sagenodus is quite reminiscent of Monongahela. The presence of only one more tooth row in Sagenodus jaws than in Monongahela jaws of the same size is an important addition to the similarities. At present, however, there are obvious barriers to a clear relationship between Sagenodus and Monongahela. Similarities exist only at the earliest ontogenetic stages of Sagenodus. As Sagenodus grows, it adds cusps and tooth rows, until at the adult condition it reveals basically different chewing motions, dietary adaptations, and ontogenetic patterns from Monongahela. Body form and skull bones are also quite different. Nevertheless, it is possible to conceive of an ancestral condition of Sagenodus from which both Monongahela and Sagenodus might be derived. Contrary to the assertions of Berman (1968), there is a striking 258 Annals of Carnegie Museum VOL. 41 Figs. 16-17. Fig. 16 Gnathorhiza dikeloda. FMNH UF 45. Right pterygoin. Ven- tral view, Unit is 1 mm. Fig. 17. Protopterus annectans. Right pterygoid. Ventral view.

Two differences are conspicious. The palate of Protopterus (fig. 17) has but three tooth blades, con- trasted with four in Paleozoic forms. Further, the proportionally longest tooth blade is the most posterior rather than the most anterior blade. It has been shown, however, that the most posterior pterygoid tooth row of Monongahela is very short in small individuals and that it is late in developing. Further, suppression of splenial tooth rows is not unusual in M. stenodonta and Gnathorhiza, and is not an improbable mechanism by which the Protopterus pattern may have been derived. It may be pointed out that two small palates of M. stenodonta (CM 19420 and I942I) apparently lack a posterior-tooth row. Differences in propor- tional length of tooth rows between the Paleozoic and the Recent are to be expected. The pterygoid bone of Protopterus is a vertically expanded element with little flattening under the tooth rows. The pterygoid bones of the Paleozoic genera are thin, flattened horizontal plates, somewhat extended under the tooth rows. The Recent fish appear to have strengthened the bony support for the palate considerably, a difference that is not anticipated in the Pennsylvanian fossils. The diet of the Recent forms varies between small vertebrates and shelled invertebrates like snails and small bivalves (Sterba, 1963, p. 846). The tooth-blades, admirably suited to such a diet, are them- selves substantially identical in form to those of the Paleozoic genera, and widely divergent from the crushing dentition of the ceratodont line and Epieeratodus. Summary The non-actinopterygian portion of the Duquesne limestone fish fauna consists of an acanthodian (microphagous?), two xenacanthid sharks ( large and small predator ) , a hybodont shark ( crushing-inverte- brate feeder), a large dipnoan (scavenger-predator-herbivore) and a small dipnoan (crustacean feeder-predator). The actinopterygian por- tion of the fauna contains small, abundant secondary and tertiary consumers only. Monongahela is a dipnoan approximating the ancestors of Gnathor- hiza, and closely approximating the ancestor of the modern Lepidosi- renidae. Although an ancestor for Monongahela is not known, the young stages of Sagenodus seem to be morphologically close to the necessary conditions. 260 Annals of Carnegie Museum VOL. 41 References Cited Agassiz, L. 1837-1843.

Volume 41 Annals of Carnegie Museum Article 9 THE INFLUENCE OF PREHISTORIC MAN ON THE DISTRIBUTION OF THE BOX TURTLE Kraig Adler Department of Biology, University of Notre Dame Notre Dame, Indiana ! I Introduction The Eastern Box Turtle {Terrapene Carolina) has a wide distribution throughout eastern North America from Maine to Florida, and west to Texas. It is a common and conspicuous element of the fauna, but its I distribution at the northern edge of its range has been difficult to deter- I mine, in part because this turtle is so often kept as a pet and then released 1 beyond its natural range. This report is a re-evaluation of distributional I records for this species from Wisconsin to Maine based on the large body I of archeological data now available from this area. Accurate determina- 1 tion of the present range is prerequisite for a discussion of the various : factors, including man, that have altered the distribution of this turtle, j ACKNOWLEDGMENTS: I thank Neil D. Richmond (Carnegie Museum), J Charles M. Bogert and George W. Foley (American Museum of Natural I History), Ernest E. Williams (Harvard University), Albert A.

Guilday (Carnegie Museum), William A. Ritchie p (New York State Museum), and J. V. Wright (National Museum of I Canada) for sending archeological specimens, dates, and information. Ij Paul S.

Deposi- tories referred to are the Museum of Comparative Zoology (MCZ) and The University of Michigan (UMMZ). Issued September 25, 1970 264 Annals of Carnegie Museum VOL. 41 This research was completed during tenure of a National Institutes of Health Traineeship (NIH 2 T1 GM 989-07). Fossil Records Fossil material of this turtle is extensive, but is in large part only from two areas (Florida and Texas), both in the southern part of the range (Auffenberg, 1958, 1967; Milstead, 1969). Very few records are avail- able from the northern part of the range that could give a clue to the distribution of this species during glacial and interglacial periods. Turtles like T, Carolina are known from the upper Pliocene and Pleistocene of Florida (Auffenberg, 1958, 1967), and the Pleistocene of New Mexico, Texas, Kansas, Arkansas, and Missouri (Milstead, 1967). Although the box turtle still exists in most of Florida, the records from southern Texas, western Kansas, and eastern New Mexico, which are beyond the present range, suggest a more southern and western distribution limit during the Pleistocene. During this period or earlier, the Texas populations were doubtless in contact with others to the south in Mexico that now have become morphologically distinct and disjunct (T. Carolina mexicana, T. c. ijucatana, T. coahiiila; Milstead, 1967). Terrapene is well known from archeological sites in Yucatan dating from the Pleistocene (Lange- bartel, 1953). Fossil T. Carolina are reported from only five localities in northeastern North America: two each in Pennsylvania (Fig. 1) and Virginia, and one in Maryland. Both Virginia localities are of late Wisconsin age: Natural Chimneys (Augusta Co.; Guilday, 1962b) and Early’s Pits (Wythe Co.; Guilday, 1962a). The Maiyland locality is Pleistocene in age (Talbot Co.; Milstead, 1965). The oldest Pennsylvania record is from Port Kennedy Cave (Montgomery Co.; Milstead, 1965), which is of Yarmouth age. Guilday et al. ( 1966) suggest a minimum date of about 1770 ± 200 years B. C. for the Bootlegger Sink Terrapene (York Co., Pennsylvania). The Bootlegger fauna contains both temperate and boreal elements and is undoubtedly the result of a long period of deposition. The box turtle, judging from its low fluoride content, was probably a late addition to the deposit. In contrast, the extensive excavations at New Paris Cave no. 4 (Bedford Co., Pennsylvania), dating 9345 ±: 1000 B. C., failed to disclose this species (Guilday et ah, 1964), and it did not turn up at Frankstown or Cumberland caves, both Pleistocene assemblages (N. D. Richmond, pers. comm.). These records, although few in number, establish the presence of Terrapene as far north as southern Pennsylvania during at least some periods of the Pleistocene. 1969 Prehistoric Man's Influence on Box Turtle 265 Fig. 1.

Numbers identifying sites refer to Table 1. 266 Annals of Carnegie Museum VOL. 41 Archeological Records Fossil and archeological records are listed separately, since prehistoric man occasionally transported turtles, including box turtles, and this means of dispersal must be taken into account. Archeological records for T. Carolina in northeastern North America (Adler, 1968; table I, fig. 1) represent material from refuse pits or burial mounds. I have seen most of this material, and have particularly examined critical records.

C-14 dates are preceded by an asterisk; others are estimates based on associated archeological material. In some cases, these dates may be accurate only for the Terrapene-hearing component. Dates are from Ritchie (1965) and Ritchie, Guilday, and Wright (pers. comm.). Numbers correspond to sites in Fig. 1; details for Michigan and Ohio records are in Adler (1968). Box turtles (or “land tortoises, Cistudo” as they often appear in some of the archeological and older zoologieal literature ) have been found at archeologieal sites in the northeast dating over the past five thousand years. The oldest record is from Lamoka Lake in central New York (site dated 3433 to 2575 B. C. ). From then until about 1700 A. D. (Kleis, 1969 Prehistoric Man’s Influence on Box Turtle 267 Oakfield, Dutch Hollow, and Garoga sites ) they were locally common in western New York, southeastern New York, and southern Ontario, areas largely beyond the present range of the species. In Pennsylvania all archeological records fall within, or only a few miles beyond, the present range (Fig. 1). Farther west, there are a few archeological specimens from beyond the present range in Ohio and Michigan, but in each case they were used as bowls and thus could have been introduced into these areas via inter-tribal trade. The two extralimital records from Michigan are each represented by a single fragment. These reeords and some material from Wisconsin originally misidentified as T. Carolina are dis- cussed elsewhere (Adler, 1968). Box turtle artifacts are also known from four sites in southern Ontario (Table 1). In all cases, however, the specimens have been made into bowls or rattles, so the possibility exists that these may have been intro- duced via trade. However, one of these localities (Lake Medad; Bleak- ney, 1958) is very near the place where the single modern Canadian specimen was found ( see below ) . The archeological records indicate the widespread occurrence of the box turtle in northeastern North America since about 3000 B. C., and suggest a reduction of its range in New York and possibly Ontario sinee 1700 A. D. The possible causes of this reduction will be discussed in more detail below. Present Distribution Conant (1958) gives the most recent map for the range of the box turtle. After careful review of the literature and new records, and after consideration of each of these in view of the abundant archeological in- formation now available (Adler, 1968; table 1), I have drawn up a new map (Fig. 1). There are significant differences between this and Conant’s map, and these differences are briefly discussed below. NEW ENGLAND The box turtle ranges through the maritime provinces of New England to and including the southern tip of Maine. There are no records for Vermont. The only two records for New Hampshire are old (Huse, 1901 ), and both in the maritime part of the state. There is a single, old record from Maine (York Co., A. A. Barden, pers. comm.). Surveys in other parts of the state, including offshore islands, have not found it. However, box turtles are known from two islands off the Massachusetts coast: Martha’s Vineyard (personal record) and Nantucket Island (MCZ 268 Annals of Carnegie Museum VOL. 41 46174 ) . Both islands were apparently separated from the adjacent main- land about 2000 B. C., according to botanical and zoological evidence (Ogden, 1958; Starrett, 1958). These two islands are located 5 and 20 miles, respectively, from the Cape Cod mainland. If these turtles did not swim these distances or were not transported by humans, this species has been present on these offshore islands (and presumably on the ad- jacent mainland) for nearly 4000 years. NEW YORK, PENNSYLVANIA AND ONTARIO Within historic times, the box turtle has never been listed as common in New York state except in the southeastern corner. Mearns ( 1898 ) said it was common along the lower Hudson Biver, from the Fishkill Moun- tains and Storm King Mountain ( Putnam Co. ) southwards. There are numerous records from Long Island (Latham, 1916) and Staten Island (Davis, 1912). Farther up the Hudson, there are two old records from near Albany (Eights, 1835; Baur in Taylor, 1895). It has apparently disappeared in that area since, as Bishop (1923) recorded no further specimens. Tlie only historic record for western New York is a single specimen from Allegany State Park (Cattaraugus Co.; Eaton, 1945), although Bishop and Alexander (1927) did not find it in their extensive survey of the Park. Werner ( 1959 ) reported a specimen from Ironsides Island (Jefferson Co.), an island in the headwaters of the St. Lawrence River. In Pennsylvania, T. corolina is not known from the northern half of the state, except along Lake Erie and near the Ohio Border. Since this turtle is not common at high elevations in mountainous regions, it seems unlikely that the western New York and Ontario populations of prehistor- ic times were derived from eastern New York, although the “Water Level Route” across central New York could have been used as an invasion route. It seems more likely that these populations reached this area via the low plains along the shore of Lake Erie, since the archeological records are more consistent with this hypothesis. There is only one modern record for Ontario (and Canada), previously unreported, from 5.2 miles east of Alberton: “there was nothing about the turtle that might have led me to suspect that it had been a captive” (C. M. Bogert, pers. comm.). The proximiU^ of this locality to an archeo- logical site for T. Carolina, namely Lake Medad, lends some support to the belief that this is a natural record. 1969 Prehistoric Man’s Influence on Box Turtle 269 OfflO, INDIANA AND MICHIGAN The distribution of the box turtle in Ohio and Indiana is apparently not as continuous as currently thought. I can find only two seemingly authentic records for a broad belt of land from the Pennsylvania border to and including east-central Indiana. Dexter’s (1955) record for Portage County, Ohio, was for a specimen actually collected in Carroll County farther south, and within the natural range of the species. However, his earlier record (Dexter, 1948) of a single specimen from Twin Lakes (Portage Co., Ohio) appears authentic. T. Carolina is known from several Cleveland parks ( Cuyahoga Co. ) but these records are discounted since the species is absent from other areas beyond the city limits. T. Carolina triunguis ( a form found generally west of the Mississippi River ) has also been taken in these same parks. It and T. c. Carolina have both laid eggs there, and newly-hatched juveniles of both were found in the parks in 1959 (C. Strong, pers. comm.). Box turtles are absent on the Lake Erie islands (Langlois, 1964), although they are abundant on the adjacent Ohio mainland. The only apparently authentic record for east-central Indiana is a single specimen collected in Adams Co. in 1953 (UMMZ 108078). Ex- tensive collecting by many persons in this region and in the part of Ohio mentioned above has failed to turn up additional specimens. Actually, there is no fossil or archeological evidence to show that this turtle was ever native to this region. Today, this area is largely under cultivation, and the moist forests that T. Carolina typically frequents have been re- duced or eliminated. It is possible that the drying conditions of the Xerothermic Interval contributed to the demise of this turtle in these parts of Ohio and Indiana, if it ever occurred there at all. In Michigan, the box turtle is known from the southwestern half of the lower peninsula. The most northern record along Lake Michigan is a specimen from Benzie County (UMMZ 108890) collected in 1953. There is only one record farther north, a single specimen collected during four summers of field work at Douglas Lake (Cheboygan Co.; Ellis, 1917), site of The University of Michigan’s biological station. Continuous col- lecting in this region since that time has failed to turn up an additional specimen (F. H. Test, pers. comm.). The northern distribution of the box turtle in Michigan (nearly to 45° North latitude) is of particular interest because it reaches only to about 43° North latitude on the Wisconsin side of Lake Michigan. Presumably, the temperature-moderating influence of the lake (caused by the high 270 Annals of Carnegie Museum VOL. 41 specific heat of water ) provides a more suitable climate on the eastern shore. The effective growing season is extended well into the fall on the eastern shore, which has resulted in a ffourishing agricultural “fruit belt” in this region. In fall and winter, the temperature of the prevailing west- erlies is often raised as much as 20° F. before these winds reach the eastern shore (Wills in Hambridge, 1941). In spring, the warm south- westerlies are cooled as they pass over the lake. The main effect is the delay of plant development — and perhaps emergence of terrestrial animals — until such time as the frequency of killing frosts is much re- duced. Only a few of the terrestrial and aquatic vertebrates found on both sides of the lake show a more northerly distribution in Michigan. I do not have sufficient information on birds to comment on their distributions or times of migration on both sides of the lake. None of the fish or mam- mals shows a more northerly range limit in Michigan, except for a mole, Scaloptis aquaticus (see Burt, 1964), but there are several examples among terrestrial amphibians and reptiles. The most striking instances are the box turtle, spotted turtle (Clenmiys guttata), and Fowler’s Toad (Bufo woodhousei) . In fact, the northern limits of the ranges of these three forms are almost exactly the same east of the Mississippi River, even to minute details of distribution ( compare ranges in Conant, 1958, Logier and Toner, 1961; Adler, 1968). In each of these, the distribution around Lake Michigan is alike, the range in Michigan extending nearly to the Upper Peninsula in the western part of the state along the lake. It is possible that these three forms have some similar sensitive point in their life histories that accounts for the resemblance in their northern distribu- tions in this region. During the spring, they live in rather different habi- tats: Biifo in temporary pools and streams, Clernmys in peiTnanent ponds and marshes, and Terrapene on land. The moderating inffuence of Lake Michigan would be expected to have rather different effects in each of these habitats. In the fall, however, the habitats of the three are similar, in that all are terrestrial. All three hibernate on land, including Clernmys (Netting, 1936). If a common limiting factor like temperature exists, the effects on the three species might be expected to be more uniform in the fall when all exist in similar habitats. I suggest that the absence of early killing frosts in the fall (in western Michigan as opposed to Wisconsin) might allow them a longer period in which to find a suitable site to bury themselves and successfully hibernate. Box turtles, for ex- ample, bury themselves in a slow, stepwise fashion requiring several days or weeks to complete. A killing frost or two in rapid succession could 1969 Prehistoric Man’s Influence on Box Turtle 271 kill such an animal before it could dig deep enough to effectively hibernate. ILLINOIS AND mSCONSIN In Illinois, Smith ( 1961 ) records T. Carolina from the southern half of the state. There are no fossil, archeological, or modern records for the northern half. The presence of this species in Wisconsin has been a matter for debate. Some authors ( for example, Dickinson, 1965 ) have confused the eastern and western box turtle (T. ornata), and their records are thus useless. Higley (1889) reported two specimens of T. Carolina from Walworth County, and Cahn (1929) mentions one from nearby Waukesha County. Both appear valid. It is doubtful that Terrapene were carried about and released in Higley ’s day as much as they are today. DISCUSSION OF MODERN DISTRIBUTION The modern limit of distribution for T. Carolina from Wisconsin to Maine, as here understood (Fig. 1), is uneven. Its northward presence along the eastern shore of Lake Michigan may be due to the tempering effects of the lake, and its presence in maritime Maine and New Hamp- shire may be due to similar moderating effects of the North Atlantic. The absence of the box turtle in large portions of Ohio and Indiana, and in northern Illinois, may be due to effects of the dry Xerothermic Interval, although there is no fossil or archeological evidence to show that box turtles ever inhabited this area. The present limited distribution of this species in New York and Ontario, and its more widespread occurrence there in prehistoric times, seem not to be explained by any of these in- fluences. The probability that some other factor is involved, namely man, is discussed below. Distributional Change in New York and Ontario We must first consider the possibility that introduction of the archeo- logical specimens of T. Carolina was via inter-tribal trade, and that the species was never native to western New York or Ontario. This possibility is considered remote since specimens are present in large numbers at many widespread localities. In at least half these places they were used for food purposes, since unworked shells and limb bones, many of them charred, have been found in several New York middens. While it is possible that some of the worked material was introduced, it is doubtful that the Indians of this region would have imported turtles for food when 272 Annals of Carnegie Museum VOL. 41 deer and other game species were plentiful locally. Indeed, the Indians of this area, particularly those of Late Woodland times, were noted for their independence and virtual lack of trade with outside tribes ( Ritchie, 1965). It is true that seashells, shark teeth, Ohio flint, and other objects were imported via trade, but there were no substitutes for these items in western New York. Thus, the specimens of this turtle recovered from burials and middens are assumed to have been collected from resident populations. Influence of Climate Changes in the ranges of organisms over time periods are often ex- plained on the basis of climatic factors, especially when there are co- incident changes in the ranges of different forms. A unique change in a single species’ range, like that which has occurred in the instance of the box turtle, is more difficult to explain. Today, the box turtle is found in tliree regions (Wisconsin, Michigan and New England; Fig. 1) at more northerly latitudes ( above 42° ) than those in which it occurs in New York. There are no obvious climatic factors, either now or since the Pleistocene, that would simultaneously explain the absence of these turtles in New York state, where they once occurred, and their presence elsewhere at more northern latitudes. The possible tempering effects of large bodies of water may account for the presence of box turtles so far north in Michigan and New England. Why then are these turtles absent today around other large bodies of water such as Lake Ontario (where box turtles once occurred)? Box turtles may well have entered New York during the warm, moist Climatic Optimum, as Guilday (in Ritchie, 1965) suggests. The later Xerothermic Interval, with its dry, prairie-like conditions, may have been instrumental in eliminating this turtle from certain parts of the Midwest, but probably did not affect populations farther east in New York. This turtle persisted in New York long after the termination of the Xerothermic Interval. More gradual climatie changes also do not seem to be implicated as a cause for extinction in western New York. A comparison of pollen profiles from western New York (where box turtles disappeared) with those from New England (where the box turtle persists) suggests more dra- matic changes in climate in the latter area. The time-span of interest is contained within the C-3 pollen zone, a sequence of deposition extending from about 100-0 B.C. to the present time (Davis, 1965). C-14 dates are not available from all profiles, nor is the C-3 zone equivalent in age at all sites under consideration. Nevertheless, the C-3 profiles are approxi- 1969 Prehistoric Man’s Influence on Box Turtle 273 mately of equal age and if they are not truncated, should give a view of floral ( and climatic ) conditions over this time period. An increase in the percentage of non-arboreal pollen, such as Plantago and Compositae, is assumed to indicate the effect of European forest clearance and, thus, a fairly complete, non-truncated C-3 zone. With these limitations, I have compared profiles in Vermont (Davis, 1965) and eastern New York (Cox, 1959) with those from west-central New York (Cox, 1959). None of these profiles appears to be truncated. Since T. Carolina is an inhabitant of open, deciduous woods ( typically beech-maple; Stickel, 1950 ) , particular emphasis is placed on the relative abundance of Fagus and Acer. Although hemlock is not commonly as- sociated with Terrapene habitats in regions south of New England, this tree is a good indicator of moisture. It is present in all profiles considered here and is used to give a relative idea of moistness. In all profiles ex- amined, the abundance of Fagus steadily decreases in C-3. In west- central New York (Bull Head Pond, Mud Lake-Tully, Perch Lake, McLean Bog), Fagus pollen gradually decreases in abundance, eventual- ly reaching 35 per cent to 70 per cent of its maximum abundance in C-3. In eastern New York and Vermont (Mud Lake-Jordanville, Consaulus Bog, Chestertown Bog, Brownington Pond), Fagus also decreases in abundance, reaching 15 per cent to 40 percent of its maximum abundance in C-3. Acer pollen is less abundant in all these profiles but shows similar trends from west to east. Tsuga is more abundant and, in general, decreases in frequency during the C-3 zone. These data suggest a warming and drying trend throughout the New York-Vermont region during the last 2000 years, but the trend is more rapid and pronounced in the East. If the box turtle is sensitive to such changes in climate, one would expect it to be most responsive in eastern New York and New England. Nevertheless, box turtles persist in the East and it follows that they would be expected to survive the apparently less drastic changes that occurred in western New York. Thus, it appears that such climatic changes were not directly responsible for elimination of the box turtle in western New York. Influence of Man A more plausible explanation for the box turtle’s disappearance in the Lake Ontario region involves the relationship between these turtles and the Indians of this area. The box turtle was important to the Iroquois and certain cognate tribes, and the time and place of its elimination is closely correlated with the chronology of prehistoric cultural development in the 274 Annals of Carnegie Museum VOL. 41 Lake Ontario region ( Ritchie, 1954 ) . Of all the Indian tribes of eastern North America, those of New York and Ontario had the longest and most intensive interest in box turtles. Judging from the burials and middens in New York state, predation on this species was intense and included both adult and juvenile specimens. At Archaic and Early Woodland sites (dating from 3500 to 0 B.C.), these turtles were used for food and as ceremonial objects as well, but mostly for the former purpose. At most sites where turtles were recovered, box turtle was the species most com- monly eaten, although the amount of meat per specimen is far less than in several of the larger aquatic species. This use is in contrast to speci- mens from Middle and Late Woodland sites (0-1600 A.D.) where the majority were used in ceremonies. The importance of the box turtle to Indians in the Lake Ontario region is particularly noticeable in the Iroquoian culture. Terrapene was the symbol of the earth or earth-bearer to the Iroquois and cognate Algon- kian tribes. Consequently, it was much revered by them and was included among ceremonial objects in most burials, even those of women and children (Ritchie, 1954). Box turtles were used in many dances as ornaments and rattles (Ritchie, 1954), and in game-hunting to invoke the aid of the demons to capture prey (Fenton, 1941). In contrast, other Indian tribes of the time considered the turtle unimportant in religion or even despised the animal. Among the Indians in the western Great Lakes region, box turtles were rarely used in ceremonies; in many of these areas the aquatic Blanding’s Turtle ( Emycloidea blandingi ) served this purpose (Adler, 1968). The Illinois and Miamis believed the earth was held up by an otter rather than by a “tortoise.” Turtle eggs and small turtles were even considered a sign of bewitchment to the Hurons of Michigan and extreme western Ontario, although some turtles (but not Terrapene) were made into rattles and others occasionally used for food (Kinietz, 1940). These Indians may also have affected box turtle populations in an- other, less-direct way. The popular belief that eastern North America was a continuous unbroken forest when the first Europeans arrived has been challenged by several recent authors ( see Day, 1953 ) . There can be little doubt that Indians, including the Iroquois, significantly altered these primeval forests. The Indians created large clearings for villages and agricultural fields. Their seasonal migrations and periodic relocation of villages extended their influence even farther. Women continuously foraged for firewood beyond the clearings and the men regularly fired the woods to drive game, to improve visibility for war purposes, and to 1969 Prehistoric Man’s Influence on Box Turtle 275 increase the supply of grass seeds. Such fires are typically fatal to terres- trial turtles and would be especially critical for juveniles with their less- protective shells. More important, perhaps, were the extensive clearings of land for cultivation of maize. The extent of these plots was often enormous, sometimes encompassing thousands of acres around a single village. The military expeditions into Iroquois country in the 18th Cen- tury often discovered large quantities of corn and grain. Sullivan’s expedition in 1779 destroyed at least 160,000 bushels of corn in a series of small villages ( Day, 1953 ) . Thus, Terrapene were denied the use of a large portion of their former habitat since these clearings were usually made in forested valleys and lowlands. The use of box turtles by New York Indians ended abruptly. As late as 1650 A.D., box* turtles ( and rarely the painted turtle, Chrysemys picta ) were used as ceremonial objects (at the Kleis and Dutch Hollow sites, for example), but by contact times the Indians had switched to the snapping turtle (Chelydra serpentina), a large aquatic form. This species was relatively common in archeological material dating from the earliest times but was then used solely for food purposes until it came into cere- monial use about 1700 A.D. The earliest record of worked Chelydra comes from a single burial at the Pen Site (Onondaga Co., New York; P. P. Pratt, pers. comm.), a site that was destroyed by Frontenac’s in- vasion, about 1685-1696. Morgan ( 1904 ) illustrates a snapping turtle rattle used about 1800. The Senecas of western New York still use Chelydra rattles today (Fenton, 1941, pis, 17, 20, 23, 24). The timing of this substitution cannot be precisely determined. Box turtles have been found in graves at Dutch Hollow (1590-1615 A.D.) and several nearby sites dating from 1550 to 1687 A.D. ( Rochester Junc- tion, Dann, Power House, Feugle, Adams, and Cameron, according to C. F, Wray, pers. comm.; none of these is mapped in Fig. 1 but they are near locality 7 ) . It is perhaps significant that the frequency of box turtles in these graves is much lower than at many earlier sites in this area. At Dutch Hollow, only 7 of 272 graves had box turtles (Ritchie, 1954) and at Rochester Junction, only 4 of 120 (Wray, pers. comm.). In addition, there is no evidence in these later excavations that box turtles were used as food, although they were commonly eaten as late as Oakfield and Zimmerman times (1400-1500 A.D.). This suggests growing scarcity of this turtle from 1500 to 1700 A.D. Some of the records of box turtles in the most recent gravesites could represent specimens that had actually been collected many years previously and made into artifacts. 276 Annals of Carnegie Museum VOL. 41 It is possible that European mans agricultural activities had some additional effect since the first pioneers in western New York arrived about 1800 (Gordon, 1940). I consider this event less likely to be the cause of the turtles’ disappearance than Indian influence, for two reasons. First, the box turtle populations were apparently already decreasing in size before 1700. Second, European cultivation in New England had seemingly not affected the box turtle populations there, at approximately the same latitude and at the edge of the species’ range. Amount of Predation To anyone familiar with the high population densities of T. Carolina in many regions it may seem naive to consider it possible that prehistoric man could be responsible for this turtle’s elimination in a region as large as western New York state and parts of Ontario. But several facts should be considered. First, the Lake Ontario region represented, originally, the range limit for this species and, as is true for most organisms, the densi- ties were probably reduced at the edge of the range where habitat is presumably less favorable. The box turtle was apparently never wide- spread in western New York, but rather localized in distribution and restricted to lowland areas. This is coupled with primitive man’s steady, selective predation for 5000 years, becoming most intensive during recent Iroquoian times; there was a marked Indian population increase about 700-900 A.D. with the development of maize agriculture (J. B. Griffin, pers. comm.). I do not think it is mere coincidence that box turtles dis- appeared from precisely that portion of eastern North America where human predation was most intense, especially when these events are correlated temporally as well as geographically. Fenton (1940) has estimated the population sizes of the various Iro- quoian tribes at contact times, from which we can get a rough estimate of the anqount of predation on box turtles for burial artifacts. These population figures are undoubtedly underestimates since European dis- eases and disruption of primitive economic patterns preceded the first observers (Day, 1953). The Five Nations of the Iroquois Confederacy, which occupied a part of western New York state, numbered at least 7000 persons when the first Europeans arrived (Fenton, 1940). If we assume that the population size was stable (including a stable age distribution) and further, that an average Indian lived 30 years, this means that l/30th of the population, or 233 individuals, died each year. Although box turtles were buried even with women and children, not all 1969 Prehistoric Man’s Influence on Box Turtle 277 graves contain shells. Possibly many shells did not survive the ravages of decay (Ritchie, 1954). Nevertheless, except for the most recent burials, some individual graves had a dozen or more shells. If there was an average of one shell per grave, this means a predation of only 233 box turtles per year in this region, a relatively small number. However, this number represents only one type of predation on the box turtle. If we add to this (1) the predation of other contemporary tribes (Hurons, 30,000 persons; Neutrals, 12,000; Eries, 8,000-10,000, at contact times), at least in part of whose territory box turtles once lived; (2) the added predation among Iroquoian and cognate tribes for food, medical, cere- monial, and hunting purposes; (3) the sustained and selective predation on box turtles for some 5000 years; and (4) perhaps most important, the destruction of much of the turtle’s original habitat, then the full effect of this predation and disruption of habitat seems evident. Thus, present evidence suggests that the box turtle, an easily collected and especially sought-for species, was eliminated in western New York by the Iroquois Indians, a situation similar to the earlier Pleistocene ex- tinctions of large mammals apparently perpetrated by man ( Martin and Wright, 1967 ) . The porcupine ( Erethizon dorsatum ) may likewise have been eliminated in Tennessee by Indians who prized the quills (Parma- lee and Guilday, 1966). In contrast, the rice rat {Oryzomys palustris) took advantage of the spread of Indian maize agriculture to extend its distribution northward about 1000 A.D. (Goslin, 1951; Smith, 1965). All these cases point to the importance of primitive man in altering postglacial distributions of certain species. Summary In northeastern North America, the range of the box turtle ( Terrapene Carolina) currently extends to central Pennsylvania, the lower Hudson Valley of New York state, most of Massachusetts, and into southern Maine. From 3500 B.C. until 1650 A.D., however, the range was more extensive in this area, extending up the Hudson Valley and including most of the western part of New York state and possibly southern On- tario. Evidence suggests that prehistoric man, primarily Iroquoian Indians, was responsible for elimination in these last-named areas. Today, the box turtle is found in three areas at more northerly latitudes than those in which it occurs in New York: Wisconsin, Michigan, and New England. Each of these three areas had resident Indian populations, but unlike those in New York state, these Indians used box turtles only rarely. In western New York and southern Ontario, predation for food 278 Annals of Carnegie Museum VOL. 41 and ceremonial purposes began as early as 3433 dz 250 years B.C. (Lam- oka Lake site) and became most intense after 700 A.D. with the develop- ment of the Iroquoian culture. Burials, including those of women and children, sometimes contain up to a dozen specimens. Added to this was the predation for food, medical, ceremonial, and hunting purposes. Per- haps more important was the Indians’ destruction of the turtles’ habitat, primarily for cultivation of maize. As late as 1650 A.D. (Kleis and Dutch Hollow sites) box turtles were still in use, but by 1700, snapping turtles (Cheltjdra serpentina) had replaced them in burials.

Maximum width of prosoma at the base of the genal spines, 23.0 mm. DISCUSSION: This species is so well known that no formal diagnosis is necessary (Raymond, 1944: 485). Although incomplete, consisting only of the prosoma, the specimen can be readily identified, for it possesses the rapidly tapering cardiac lobe characteristic of E. danae. E. packardi Willard and Jones has a similar cardiac lobe, but the prosoma is relative- ly wider. E. packardi is also described as having a rather strong posterior notch at the base of the cardiac lobe (Willard and Jones, 1935: 1277). This feature could not be discerned on a cast of the holotype from the Carnegie Museum collections (CM 23459). The width/length ratio of the upper Freeport specimen is less than that of typical specimens of E. danae. The very short genal spines and the relatively small size of this specimen also suggest that it represents a young individual. The prosoma is unusually well preserved, only slightly wrinkled, with the ocelli prominent. The transverse bar at the midpoint of the cardiac lobe is also preserved.

The Ohio specimen may repre- sent a slightly more mature individual than the holotype of E. packardi (CM 23459), for it has a longer thoracetron. Euproops danae can be distinguished by the presence of prominent transverse ridges on the thoracetron and by the abruptly tapering cardiac lobe. Euproops darrahi Raymond of the Mason shale of Pennsylvania is probably a junior synonym of E. packardi. This is only the second reported specimen of E. laevicula. It is of particular interest because of the close agreement with Raymond’s original description. In a group like the Xiphosura, one should be ex- tremely cautious in proposing new species. Considerable variation may be expected between individuals of the same species, fossil specimens are rare and usually distorted by crushing, and there is the further diESculty of molt stages and sexual dimorphism. Raymond might in fact be sus- pected of a needless proliferation of species based upon very slender evidence, arbitrary criteria, and often only single specimens. These two new specimens can readily be assigned to existing species within Ray- mond’s scheme of classification. The conclusion to be drawn is that Raymond’s classification, though artificial, is internally consistent, fairly conservative, and may suffice until a thorough, modem reappraisal of this group is undertaken. The Upper Freeport Roof Shale Fauna Associated fossils at the xiphosuran locality include the estherid Cyzicus sp., which has been found in both the black fissile shale and the ironstone nodules. The black shale also yields abundant ganoid (Haplo- lepis) and crossopterygian fish scales. Ostracods {Candona and Guts- chickia) are also common in the nodules. A single blattoid wing has been identified by C. J. Durden as Stygetohlatta. A conspecific specimen has been found in the Mason shale of Pennsylvania (C. J. Durden, personal comm.. Sept. 5, 1967). Examination of other outcrops of the upper Freeport roof shales in Madison, Center, Hanover, and West townships reveals that the black fissile shale bed is widespread, with abundant ganoid scales and occasional Xenacanthus teeth. One fragmentary insect wing, identified by C. J. Durden as either Mylacris or Orthomylacris sp., has been found by R. Max Card, Lisbon, Ohio, in an exposure along U. S. Route 30, NE/4 24, Hanover Township, Columbiana County, Ohio. At this locality fossiliferous ironstone concretions occur sparingly, containing a few fresh-water ostracods. Estheriids (Leaia) occur in a section measured 1969 Euproops From the “Uffington Shale’ 285 by Stout and Lamborn (1924: 258) at West Point, Madison Township, and in a strip mine in West Township, though in both instances the unit is a silty shale overlying the black fissile shale. Normal marine fossils have not been found overlying the coal. With the exception of a Perry County locality cited by Sturgeon (1958: 92), where the brackish-water forms Lingula and Orbiculoidea occur sparingly, no brachiopods or molluscs are known from the beds immediately overlying the upper Free- port coal. STRATIGRAPHIC DISCUSSION: The stratigraphic problem has been con- fused by recognition of a marine Uffington shale member that does not exist (Sturgeon, 1958: 92). Sturgeon failed to note that the marine Uf- fington shale of the type area, Morgantown, West Virginia, was long ago found to have been based upon a misidentified outcrop of the Mahoning coal and Brush Creek shale member. Nor did he note Price's (1917) redescription of the Uffington as a non-marine, plant-bearing shale im- mediately overlying the upper Freeport coal. A definite marine member overlying the upper Freeport coal would certainly deserve formal strati- graphic recognition, but the presence of two brackish-water brachiopod species at the Perry County locality is a poor foundation on which to erect a new marine member. The Columbiana County localities cited by Sturgeon ( Stout and Lamborn, 1924: 238, 258 ) were originally described only as “fossiliferous,” and collecting at these localities has shown that Sturgeon's belief that these fossils are marine is ill-founded. If a marine zone were discovered over the upper Freeport coal, it could not be called Uffington, for that name belongs to the non-marine, plant-bearing unit of Price. Price’s Uffington shale, incidentally, though recognized in the USGS lexicon, is probably deserving of no more than bed rank. The same is true of the black, fissile shale which is usually found between the coal and the Uffington shale or between the coal and the Mahoning sandstone member when the Uffington is absent. This black shale unit is presumably equivalent to units 2 and 3 of Cross’s typical Dunkard cyclothem (Beerbower, 1961: 1031). Typical Uffington shale, as described by Price, and the black fissile roof shale bed are both present in Athens County, Ohio, but neither can be considered important enough to be termed a member.
