TWENTY-FIRST ANNUAL REPORT aati 
to scientific research at the Tropical Station in British Guiana 
by Mr. Beebe, and were illustrated by Mr. Paul G. Howes. Num- 
ber 5, contributed by Prof. EK. W. Gudger, was an interesting 
paper on the Gaff-Topsail Catfish. 
Zoopathologica.—Because of the wealth of material in the 
Society’s possession on the diseases of animals, a new publication 
was created to better place this matter at the disposal of scien- 
tific men interested in this branch of our work. Dr. George A. 
MacCallum contributed the first paper, “‘Parasitic Trematodes 
of Marine Fishes.” Other papers are in course of preparation. 
Annual Meeting.—A series of motion pictures, showing the 
development of antlers of the Wapiti, the work of the beaver, the 
life of a gray squirrel, the temperament of a savage zebra, and 
pictures of emeu, Alaskan bears, sea-lions, gorilla, and various 
other mammals taken in the Park by the Department, were ex- 
hibited at the Annual Meeting of the Society.

FUTURE DEVELOPMENTS. 
The most important need of the future is an increase by the 
Board of Estimate and Apportionment of 10 per cent. to the 
salaries of all the employees of the Zoological Park who receive 
less than $1,300 per year. It is hoped that this end can be ac- 
complished in the making up of the financial budget of expendi- 
tures for 1918, and every effort will be made to bring about that 
result. An additional appropriation of $11,480 will be required 
for this purpose. We also must have a fund for necessary re- 
pairs to buildings, at least $10,000 a year, such as is provided for 
the American Museum of Natural History.
