p I tie ILLINOIS ZOOLOGICAL SERIES OF FIELD MUSEUM OF NATURAL HISTORY Volume 24 CHICAGO, OCTOBER 20, 1943 No. 26 PERUVIAN SNAKES FROM THE UNIVERSITY OF AREQUIPA BY KARL P. SCHMIDT CHIEF CURATOR, DEPARTMENT OF ZOOLOGY AND WARREN F. WALKER, JR. HARVARD UNIVERSITY A considerable collection of snakes and of some other reptiles and amphibians in the collection of the University of Arequipa, at Arequipa, Peru, was lent to the senior author in 1939 through the courtesy of Dr. Corzo Masias, of the Department of Zoology, and at the suggestion also of Dr. Carlos Nicholson, Professor of Bio-geography at the university. This material, all unidentified, was partly without data as to locality; but a series of specimens from the faunally little-known Department of Madre de Dios gives it suffi-cient importance to warrant publication of a list of the forty-seven species of snakes in the collection. Two species are described as new. Much of this collection was assembled through the efforts of the late Dr. Edmundo Escomel, long resident in Arequipa. The specimens without data are undoubtedly all from Peru, and most of them are probably from the Department of Madre de Dios. The remaining material comes from the following localities or regions: Chanchamayo: A tropical lowland locality at the headwaters of the Rio Peren6 in the Department of Junin. Montana: A term used for the forested tropical lowlands of eastern Peru. Madre de Dios: A department of Peru, much of it a tropical lowland region bordered by mountains on the south. Selvas de Sandia: The tropical lowlands below Sandia in the Department of Puno. Boundary of Peru and Bolivia: Collections resulting from a boundary survey expedition, departments of Puno and Madre de Dios. No. 532 279
