68 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1919'. 
Deposited. — As usual, a number of desirable exhibition speci- 
mens were accepted on temporary deposit. These included for the 
year 7 parrots of various species, 2 boa constrictors, a lion, and a 
Idnkajou. Eight alligators were carried over the winter for the 
Pan American Union. 
REMOVALS. 
Surplus mammals and birds to the number of 37 were exchanged 
to other zoological collections, as follows : One European brown bear, 
1 hippopotamus, 2 red kangaroos, 1 yak, 3 Indian antelopes, 1 fallow 
deer, 2 hog deer, 1 Japanese deer, 4 barasingha deer, 4 European red 
deer, 6 gray squirrels, 2 domestic geese, and 9 peafowl. A number 
of specimens on deposit were returned to owners. 
While the death rate for the year has been comparatively small, 
there have been as usual some serious losses, especially among animals 
long in the park and of advanced age. The male Celebesian dwarf 
buffalo, or anoa {Anoa depressicoimis) , which has been a feature of 
the antelope house for nearly 13 years, died on July 24, 1918. This 
animal came to the collection December 12, 1905, then fully adult, 
had been showing extreme age for the past two years, and his death 
was not unexpected. Tavo female Congo harnessed antelopes {Tra- 
gelaphus gratus) were lost. One was purchased as a fully grown 
animal October 31, 1907, and died May 10, 1919. The other, born in 
the park July 4, 1912, died February 27, 1919. An old female Ameri- 
can bison, purchased May 6, 1907, died of septic metritis on April 20, 
1919. A female guanaco, received from the zoological gardens in 
Buenos Aires, December 29, 1904, died on August 22, 1918, of acute 
congestion of the lungs, after 13 years and 8 months of life in the 
park. An alpaca, also from the Buenos Aires gardens, received 
March 14, 1908, died from old age and parasitic invasion, October 11, 
1918. A wild cat {Lynx ruff us)., received September 3, 1907, died 
January 22, 1919; and a Canada lynx, received September 25, 1907, 
died from septicemia September 25, 1918, exactly 11 years from the 
date of its arrival in the zoo. Other losses of importance among the 
mammals were a leopard, from pneumonia, November 18, 1918, and 
a young Brazilian tapir, born in the park February 22, 1918, which 
died under anesthetic during an operation for prolapse of the rectum 
on June 3, 1919. 
The most serious loss by death among the birds was a female 
trumpeter swan, which died of septicemia May 14, 1919, just after 
it had been successfully mated, after two years of effort, with the 
male trumpeter lent to the park by Judge R. M. Barnes, of Lacon, 
111. The eggs in the ovary were enlarged to the size of cherries, and 
there is every reason to believe that but for the untimely loss of this
