MAMMALS OF THE COLLINS-DAY SOUTH 

 AMERICAN EXPEDITION.* 



BY WILFRED H. Q.SGOOD. 



In the latter part of 1914, Mr. Alfred M. Collins of Philadelphia 

 and Mr. Lee Garnett Day of New York called upon the writer to discuss 

 plans for a trip to South America. As a result of this meeting and 

 several subsequent ones, it was decided by Mr. Collins and Mr. Day 

 that they would not only finance but personally conduct an expedition 

 to be largely devoted to the collecting of natural history specimens, 

 especially mammals and birds. As finally arranged, the party included 

 Mr. Collins and Mr. Day and their friend Mr. Willard Walker, who also 

 shared in the expense, and representatives of two museums, Mr. George 

 K. Cherrie for the American Museum of Natural History of New York, 

 and Mr. Robert H. Becker for the Field Museum of Natural History. 

 The route chosen led across the continent of South America from west 

 to east through Peru, Bolivia, and Brazil. Sailing from New York 

 December 26, 1914, the party proceeded via Panama to Mollendo, 

 Peru, arriving there on January 15, 1915. Thence they proceeded by 

 rail to Arequipa, from which place a short but successful hunting trip 

 was made to Pampa de Arrieros, Peru, where specimens of guanacos 

 and vicugnas were obtained. Another short stop was made at Puno 

 on Lake Titicaca and from there quick time was made by rail and stage 

 via La Paz, Oruro, Arque, and Parotani to Cochabamba, Bolivia. 

 From Cochabamba it was decided to travel by pack train over a little- 

 used and difficult trail to the port of Todos Santos on the Chapare" River, 

 an affluent of the Mamore". Owing to heavy rains, this part of the 

 trip was very arduous, but it was successfully accomplished and some 

 collecting was done in spite of untoward conditions. On March i6th 

 a small steamer left Todos Santos with the expedition and arrived at 

 Trinidad on the Mamore' March 2oth. Four days later Guajaramerim 

 was reached and thence to Porto Velho on the Madeira the party went 

 by rail, arriving March 29th. From this point to Manaos, no stops 

 were made and, with the exception of Mr. Cherrie who remained on 



*An illustrated general account of this expedition written by Mr. Day was 

 published in the American Museum Journal for January, 1916.
