102 NEW YORK ZOOLOGICAL SOCIETY 



States Bureau of Fisheries supplied eggs of the quinnat and sil- 

 ver salmons from Washington and Oregon, whitefish from the 

 Great Lakes and yellow perch from Maryland. The Southside 

 Sportsmen's Club and the Tuxedo Club furnished eggs of the 

 brook, rainbow and steelhead trout from their private hatcheries. 



Public school teachers and their classes were aided in every 

 possible way, and the usual number of balanced aquaria stocked 

 for use in their schools. With ample space set aside for the use 

 of teachers and their classes in a larger building, this phase of 

 public instruction should become a much more important and 

 regular feature of our work. 



It was possible to aid a number of scientific men in their re- 

 search by supplying them small marine forms for carrying on 

 their work; some of which was done in the laboratory of the 

 Aquarium. Mr. George C. Scott, Instructor in the College of 

 the City of New York, was supplied with specimens of dogfish 

 and laboratory space for carrying on his studies upon the circu- 

 lation of the blood in fishes. 



Dr. Jacques Loeb, who has been making inquiries relative to 

 the role of salts in the maintenance of life, received killifishes at 

 regular intervals. Prof. C. F. W. McClure of Princeton received 

 embryos of salmonoid fishes in various stages of development for 

 study on the origin and development of the lymphatic system. 



Dr. R. C. Osburn discovered the presence of a species of 

 crayfish, (Cambarus limosus), new to New York, in the lakes of 

 Central Park and Prospect Park, where it is abundant. This 

 species, which is common in the drainage of the Delaware, Sus- 

 quehanna and Potomac rivers, has not previously been recorded 

 outside of this range. An entirely new and very striking color 

 variety of this species has been discovered by him along with the 

 normal form. The Aquarium Numbers of the Zoological Society 

 Bulletin issued during the year were prepared by Dr. Osburn. 



Assistance was rendered to city authorities and individuals 

 in Boston, Buff"alo, Philadelphia and San Francisco in connection 

 with plans for proposed public aquariums in those cities. 



No special improvements in the building were made duiing 

 the year except such as were necessary for additional office space. 

 For the most part the repairs required were of a minor char- 

 acter and were chiefly due to the corrosion of piping and pumps
