90 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1920. 



This animal was at least 4 years of age when it arrived at the park 

 and was therefore fully 19 years old at the time of its death. The 

 Grevy's zebra stallion, presented by Emperor Menelik, of Abyssinia, 

 to President Roosevelt, which reached the park November 24, 1904, 

 died, after over 15 years of life in Washington, on December 4, 1919. 

 A pair of Japanese monkeys, received August 4, 1904, fully adult at 

 the time, died during the year, the female on December 7, 1919, and 

 the male on January 21, 1920. Autopsies in both cases showed splenic 

 tumor as the immediate cause of death. A California lynx died 

 from pyemia on September 23, 1919, almost 14 years after the date 

 of its arrival, October 19, 1905. A female coyote, received April 26, 

 1906, was mercifully killed on June 10, 1920, as it was virtually 

 helpless with disabilities of old age. An aged female Florida otter, 

 received July 20, 1907, died on March 20, 1920, almost 13 years after 

 its arrival in the park. Among birds long in the collection, a dem- 

 oiselle crane, received July 2, 1903, was accidentally killed October 

 18, 1920; a crowned crane, received on May 25, 1905, died from en- 

 teritis December 26, 1919 ; and a red-and-blue macaw, received Janu- 

 ary 26, 1907, died on September 8, 1919. 



Other serious losses during the year include a wombat, from 

 pneumonia, August 5, 1919; the waterbuck, killed as unfit for ex- 

 hibition, on November 5, 1919, after nearly 10 years of life in the 

 antelope house; a hornbill, from enteritis, August 19, 1919; and our 

 last specimen of the blue-headed quail dove, January 16, 1920.
