90 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1925 



A small number of animals were received in exchange for surplus 

 stock from the collection. 



The Biological Survey, United States Department of Agriculture, 

 transferred a number of animals taken by field agents of the bureau, 

 including some large western ravens, western porcupines, two sand- 

 hill cranes, and two whistling swans. 



Deposits. — Among the animals received on deposit, which repre- 

 sented species not exhibited in the collection, were a sarus crane, a 

 jabiru stork, and a pair of adjutants, deposited for a time by Mr. 

 Victor J. Evans. Of species placed on deposit which were new to 

 the park records, a lesser white-nosed guenon is especially notable. 



REMOVALS 



Forty-one birds and mammals were sent aAvay in exchange to other 

 zoological gardens during the year. Among these were two elk, an 

 Indian buffalo, two American bison, six red deer, four Japanese deer, 

 and a llama. 



Nine animals and birds on deposit were returned to their owners. 



The average mortality among the animals remains low, despite 

 numerous losses during the year, chiefly among aged animals, long 

 on exhibition. These losses, however, have been very serious, as they 

 include a bull eland that had lived in the park since 1916, a Grant 

 zebra received in 1909, a Rocky Mountain sheep ram received in 1917, 

 Barbados sheep, reindeer, a wart hog, two lions, a male Axis deer, 

 an African leopard that had lived in the park since 1909, and an 

 African rhinoceros that had been in the collection only 18 months. 

 Most of these animals were the only representatives of their species 

 in the collection, and their loss creates gaps that can be filled only 

 by purchases involving expenditures of far more money than is 

 available. 



Losses among reptiles are so heavy unless adequate arrangements 

 are made for their care, that it is useless to attempt to maintain a col- 

 lection in this group, except of a few hardy types, until proper quar- 

 ters are provided for them. 



Post-mortem examinations of animals that died were made, when 

 desired, by the pathological division of the Bureau of Animal In- 

 dustry. 



The following list shows the results of autopsies, the causes being 

 arranged in groups :
