Bull. Mus. Comp. Zool., Harvard Univ., 131 (IJ) : 403-428, Sept., 1964 No. 12 — Anolis cqucstns in ()>•{( ntc I'rorincc, Cuba By Albert Schw.xhtz ' IXTHODIC'TIOX In 1!)58, [ reviewed the suhspeeies of the C'uban <;iaiil uiiole. Anolis equestris. At that time, the only .specimens from Orients, the ea.sternmost Cuban provinee, were .sixteen individuals, all in rather poor condition and most of which had been in j)i'eservation for some time. Also, of these sixteen, nine were from the north-western coast of Oriente and represented the subspecies thomasi, thus leaving only seven lizards from the remainder of the prov-ince. Since tiiat time, 1 have collected a series of these anoles in Oriente, under National Science Foundation grant (J-()2r)2, in the summers of 1959 and I960; in addition, in the belief that Oriente equestris could best be treated as a unit and on the basis of all available material, Dr. Ernest E. Williams has invited me to study certain .specimens he was intending to describe, as well as certain comparative material obtained in Cuba under XSF Grant G-16066 or borrowed by him from the Hamburg Museum. The gathering together of all this material makes it possible to clarify the Oriente picture a bit more satisfactorily, although all questions are by no means answered. I wish to thank Ronald F. Klinikowski, David C. Leber, James D. Smallwood, and Barton L. Smith for th(Mi-assistance in the field. Mr. Klinikowski has also made the illustrations for the present paper. In addition to specimens borrowed from the Museum of Comparative Zoology (MCZ), the Hamburg Museum (HM), and the American Museum of Natural History (AMNH), for which I wish to thank Dr. Ernest AVilliams, Dr. Werner Ladiges, Charles M. Bogert, and Dr. Richard G. Zweifel, I have examined material from the Carnegie ^Museum (CM) under the care of Neil D. Richmond, and the Museo y Biblioteca de Zoologia de la Habana (]\IBZH) which was formerly under the curatorship of ]\Iiguel L. Jaume Garcia; specimens from the United States National Museum (IJSNM) are currently not avail-able, but I have previously taken scale counts and measurements on the pertinent specimens in that institution, and the loans were made at that time by Dr. Doris M. Cochran. All these curators deserve my sincere thanks for their cooperation. 1 Present address: lO.OOO S.W, s4tli Street, Miiiiiii 4:!. Florida.
