TWENTY-FIRST ANNUAL REPORT 111 



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. E. W. Gudger, was an interesting 

 paper on the Gaflf-Topsail Catfish. 



ZoopatJiologica. — 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.
