NO. 5 MAMMALS OF PANAMA GOLDMAN 1 7 



mammals were also collected at various localities by Mr. Henry 

 Pittier, Mr. W. R. Maxon, Dr. S. E. Meek, Mr. S. F. Hildebrand 

 and Mr. August Busck, members of the Smithsonian survey party 

 engaged chiefly in other investigations. 



In February, 1912, Mr. Wilfred H. Osgood and assistant passed 

 through the Canal Zone en route to South America, and while wait- 

 ing about a week for the steamer at Balboa collected mammals, 

 mainly bats. One of the results of his brief work at that point was 

 the re-discovery of Liomys adspersus Peters, the exact habitat of 

 which was previously unknown. 



During the years 1914 and 191 5 several collections were made in 

 Panama for the American Museum of Natural History. In February 

 and March Mr. George Shiras, 3d, well known as a student and 

 photographer of North American mammals, visited the Canal Zone. 

 His work centered in the Gatun Lake area and the results were 

 published the following year. Mr. Shiras was accompanied by 

 Mr. H. E. Anthony, who secured collections of mammals. In 

 October, 1914, the American Museum of Natural History sent 

 Mr. William B. Richardson to eastern Panama, where he collected 

 mammals and birds in the lowlands of the Tuyra Valley until the 

 middle of February, when he met Mr. H. E. Anthony and Mr. D. S. 

 Ball, of the same institution, at Panama. The party outfitted and 

 on February 8 proceeded by launch to Real de Santa Maria. From 

 this point it ascended the Rio Tuyra to the limit of canoe navigation 

 at Tapalisa. Richardson remained at Tapalisa several weeks, while 

 Anthony and Ball continued into the mountains to the old Indian 

 village of Tacarcuna, where collecting was carried on at an elevation 

 of 2,600 feet. Late in March a camp was established for work at 

 5,200 feet altitude on the upper slopes of Mount Tacarcuna. About 

 the middle of April they were forced by the rainy season to abandon 

 work at the higher elevations. Mr. Anthony and Mr. Ball returned 

 to New York, but Mr. Richardson spent the latter part of April and 

 the month of May collecting at Cituro and Boca de Cupe, in the 

 lowlands of the Tuyra Valley. A general report on the mammals 

 obtained by these expeditions has been published by Anthony (1916). 



While the Canal Zone and other limited sections of Panama are 

 now fairly well known, large areas, including important mountain 

 ranges, remain unexplored. One of the least known parts of Panama 

 is the elevated region between the headwaters of the Rio Bayano and 

 the Rio Chucunaque, an area until very recently, at least, controlled 

 by the San Bias Indians, and from which other natives of Panama,
