NO. 2333. MAMMALIA COLLECTED IN PERU BY HELLER— THOMAS. 219 



Jelski and Kalinowski worked, and localities on the Rio Perene and 

 Eio Inambari, where that fine collector, P. O. Simons, secured for 

 us the first Peruvian series ever made in modern fashion. The last 

 named also went to many other localities in Peru and Bolivia, and 

 the majority of the species I have described were discovered by him. 

 The only other modern Peruvian collection of importance is that 

 recently made in the northwest by Messrs. Osgood and Anderson, 

 and worked out by the former in 1913 and 1914. None of these col- 

 lections, however, is anything like so complete a representative of its 

 locality as the present one, which probably surpasses any other ever 

 made in South America. Mr. Simons moved about too much to have 

 worked any one locality as well ; Messrs. Osgood and Anderson were 

 merely passing through ; while no one else of equally trained ability 

 has entered the country. 



The following is a list of f aunal publications relating to the mam- 

 mals of Peru, but of course much if not most of the literature is in 

 the form of scattered observations on the different animals : 



1844-1846. TscHUDi, J. J. von. Fauna Peruana. Mammalia, pp. 1-262. In 

 an effort to make it appear complete the accounts of the species in this work 

 have been made so generalized as to deprive them of much of their value. 

 This is notably the case with the geographical distributions, which even in 

 the case of rare species are usually in quite general terms, without mention of 

 particular localities.
