 COLLECTED BY THE PERUVIAN EXPEDITION OF 1914- 

 1915 UNDER THE AUSPICES OF YALE UNIVERSITY 

 AND THE NATIONAL GEOGRAPHIC SOCIETY.

Mr. Edmund Heller, who was engaged as naturalist by the Peru- 

 Wan Expedition of 191-lr-1915 under the auspices of Yale University 

 and the National Geographic Society to southern Peru, collected a 

 number of amphibians and reptiles. While Mr. Heller's primary 

 interests were mammals and birds, nevertheless he secured some in- 

 teresting lower vertebrates. Not a few of these, notably the Teiids, 

 were caught in his cyclone traps set for small rodents. Unless other- 

 wise mentioned all of the specimens considered here were collected 

 by Mr. Heller. 



There is considerable diversity of usage in the spelling of some of 

 the place names. For example, Machu Picchu is sometimes and 

 probably correctly spelled Macchu Picchu. In this paper we have 

 followed the spelling used on a map compiled for the expedition by 

 A. H. Bumstead, C. F. Maynard, and others. 



It is a pleasure to thank Dr. Hiram Bingham, leader of the expedi- 

 tion, and the authorities of the National Geographic Society and of 

 the United States National Museum for the privilege of studying 

 and reporting upon this collection. By the articles of agreement 

 under which the collections were made they become the property of 

 the United States National Museum. A series of duplicates has, 

 however, been added to the collections of the Museum of Compara- 

 tive Zoology by j)ermission.
