THE UNIVERSITY OF KANSAS SCIENCE BULLETIN Vol. XXXIV, Pt. I] October 1, 1951 [No. 4 Notes on a Small Herpetological Collection from Guerrero BY Charles W. Hall Arstract. A collection of snakes and lizards made in the vicinity of Chil-pancingo, Guerrero by W. Wilmot Brown is reported. A single new subspecies, Coniophan.es piceivittis taylori is described. This paper is based on a small collection of Mexican reptiles ac-quired by the Kansas University Museum of Natural History from Mr. W. Wilmot Brown. The collecting was done within a 15 km. radius of Chilpancingo, Guerrero. Unfortunately neither exact localities nor approximate elevations are appended but undoubt-edly certain specimens came from considerably higher elevations than the city itself. Chilpancingo is located on the Mexico-Aca-pulco Highway at an elevation of approximately 1380 meters. The city lies on the southern drainage of the Sierra Madre del Sur. The famous collecting locality, Omilteme, (elevation 2460 meters) is located about ten kilometers west of Chilpancingo. To the west of the city, the mountains of the Sierra Madre del Sur range rise rapidly to reach a maximum elevation of 3700 m. and extend westward for about 275 km. where the range terminates at the Rio Balsas. To the eastward the mountains are somewhat lower than at Chilpancingo. This low pass divides the Sierra Madre del Sur from its extension into Oaxaca. The range is separated from the Mexican Plateau on the north by the Balsas Basin and is isolated on the south by the Pacific Ocean. It is in this area that a great number of endemic species are found. Taylor * has reported 64 endemic species of reptiles and Amphibia in this region ( 1940 ) . The most surprising character of the fauna has to do with the absence of all salamanders save for what is regarded * Taylor, E. H., "Island" Faunas on the Mexican Plateau; Proc. Eighth Amer. Sci. Cong., vol. Ill, Biol. Sci., pp. 503-504. (201)
