1885.1 "'" LCope. A contribution to the Herpetology of Mexico. By E. D. Cope. {Read before the American Philosophical Society, April 17, 1885.) I. THE COLLECTION OF THE COMISION CIENTIPICA. This collection has been on exhibition in the department of Mexico in the World's Exposition at New Orleans the present winter. Through the courtesy of the Commision, and especially of Dr. Fernando Ferrari Perez, the Director, I had the opportunity of making an examination of it. The following catalogue is valuable on account of the precision with which the localities can be fixed, which is a point of first importance in the zoology of Mexico. The collection was made in the States of Vera Cruz and Puebla, and the localities mentioned are all in the Tierra Templada. Batrachia. Spelerpes bellii Gray. Jalapa, Vera Cruz. BtJFO iNTERMEDius Gthr. Yzucar de Matamoros, Puebla, BuFO AQUA Daud. From the belly of a Sibon annulatum. Hyla nigropunctata Boul. Teziutlan, Puebla. Hyla gracilipes Cope, Puebla. Said to be very abundant near the city of Puebla. I have led Dr. Boulenger (Catalogue British Museum) into error with regard to this species by accidentally inverting the relative sizes of the eye and tympanic disc in describing them. The disc is one-half the diameter of the eye, and not the reverse. In the Puebla speci-mens the posterior digits are a little shorter than in the type. Smilisca baijdini D. and B. Jicaltepec, Vera Cruz. LiTHODYTES RHODOPis Cope. Pucbla. Lacertilia. Anolis ? SALL^i Gthr. Jicaltepec. Phrynosoma orbiculare Wiegm. Teziutlan. Uta bicarinata Dum. Yzucar de Matamoros. This locality greatly extends the range of this species, which has hitherto only been known from the West Coast and the Plateau. Sceloportjs microlepidotus Wiegm. Teziutlan. ScEiiOPORTJS ^NEUS Wiegm. Yzucar de Matamoros. Sceloportjs spinosus Wiegm. Tlapanala Puebla. ScELOPORUS VARIABILIS Wiegm. Jicaltepec ; Matamoros. ScELOPORUS GRACiostrs B. &. G. var.
