TWENTY-SIXTH ANNUAL REPORT 121 



One of the California sea-lions gave birth to a pup on June 

 13, but after a few days refused to care for it. Although daily- 

 efforts were made to feed it, the young sea lion died on June 29. 



Mr. Ernest Napier, President of the New Jersey Fish and 

 Game Commission, presented an alligator seven feet long on 

 May 23. 



The United States Bureau of Fisheries has continued to 

 supply eggs of food and game fishes from federal hatcheries, 

 for the operation of the Aquarium's fish hatchery. The species 

 hatched during the year were lake, rainbow and black-spotted 

 trout, land-locked and chinook salmon, pike-perch, whitefish and 

 herring. The young fishes were delivered as usual, to the fishery 

 boards of New York and New Jersey for distribution in public 

 waters. 



Through the courtesy of the New Jersey Fish and Game 

 Commission, the Aquarium secured on May 24, 809 fishes from 

 Boonton Reservoir, consisting chiefly of yellow perch, pickerel, 

 black bass, calico bass and sunfish. 



The Aquarium made an exchange with the Fairmount Park 

 Aquarium in Philadelphia on November 23, securing 74 fishes 

 of five different species. 



Employes of the Aquarium collected specimens of several of 

 the smaller and commoner fresh- water fishes in lakes of the City 

 parks. 



In October, Mr. E. K. Bruce of Thornburg, Iowa, presented 

 141 fancy goldfishes of several varieties — comets, fantails, shu- 

 bunkins and straight-tails. 



Major Philip Benkard of New York presented a handsome 

 table aquarium of large size. 



For one year, from the fall of 1920 to the fall of 1921, scales 

 of whitefishes which have lived in the New York Aquarium since 

 hatching in the Aquarium troughs in January 1913, were sup- 

 plied for scientific study to biologists in Michigan and Canada. 

 Scales were sent each month from specimens segregated for the 

 purpose, and some interesting things discovered, not only with 

 reference to scales, but, by checking up our findings with those 

 of other observers, some important facts were ascertained re- 

 garding the spawning age and probable longevity of the white- 

 fish. Miss Mellen's paper on the subject will be published in 

 Zoologica.
