SUPERINTENDENT'S REPORT. 
To the Board of Directors of the Zoological Society of 
Philadelphia: 
Gentlemen: — I beg to submit my report for the year 
ending February 28th, 1913. 
Total number of animals exhibited in each class dur- 
ing the year: — 
Mammals 552 
Birds 959 
Reptiles 586 
Amphibians 21 
2,118 
The accessions of species not previously exhibited in 
the collection were : — 
Hainan Gibbon {Hylohates hainanus Thomas). 
Habitat, Island of Hainan and, possibly, South China. 
A handsome male of this species was presented, on 
September 22d, by Dr. Thomas Biddle, of the So- 
ciety's directorate, who obtained it in London and 
brought it personally to this country. This is an 
exceedingly rare animal and, probably, had never 
before been seen alive in America. With this ac- 
quisition we are able to show two species of these 
delicate primates; the other, a male White-handed 
Gibbon, has been in the Garden since July, 1906, 
and it is beUeved that this is a record period in cap- 
tivity for any of the genus. 
Schmidt's Monkey (Cercopithecus schmidti Matschie). 
Hab., interior of Eastern Africa. 
Two males of one of the rarest of the white-nosed 
group of monkeys were obtained from a local dealer 
on April 6th. 
Azara's Douroucouli {Aotes azaroe Humboldt), 
Hab., Argentine Republic.
