A male and a female were received through James Annin jr" 

 from Upper Saranac lake Nov. 16, 1895. Both fish were nearly 

 spent. They were believed to be the common whitefish. A 

 male from Chazy lake arrived through the same source Nov. 22, 



1895. It was doubtfully called " blackfin whitefish." At that 

 time the fish had left the spawning beds and were in deep water. 

 June 17, 1896, a female 19| inches long was shipped by Mr Annin 

 from Canandaigua lake. Its stomach is pear-shaped with walls 

 more than I inch thick; it contained numerous small shells of 

 several genera, not yet identified. 



The species is reported by fishermen to be very abundant in 

 that lake, and to be destructive of eggs of other fish. They say 

 it comes in great numbers into shallow water near the shore in 

 early summer when the water is roily, and can be caught on 

 set lines. Mr Annin saw men baiting their set lines with small 

 minnows on Canandaigua lake, and, when the lines were taken 

 up in the morning, the whitefish was found on the hooks. It 

 is said that one so taken weighed 6 pounds. Sup't O. H. 

 Daniels, of the New Hampshire fish commission, forwarded a 

 specimen from Lake Winnesquam, at Laconia, 19^ inches long, 

 weighing 46 ounces, and he wrote that individuals weighing 7^ 

 pounds had recently been taken. The species was called " blue- 

 fin " and whitefish. 



The fish-eating habit of the whitefish was fully verified in the 

 aquarium on examples obtained in Canandaigua lake in November 



1896, by Mr Annin. Knowing that the species usually subsists 

 on small mollusks and crustaceans, efforts were made to provide 

 the fish with P h y s a and Gammarus; but this became 

 difficult in winter, and an experiment was made with small 

 killifish (Fundulus heteroclitus and m a j a 1 i s), 

 which proved satisfactory during the cold months. In summer, 

 however, it was found necessary to return to the use of Gam- 

 marus. The whitefish at first took the killifish without any 

 eagerness, but they soon learned to chase their prey and take 

 it much as trout do. 



A female received from Canandaigua lake June 17, 1896, in 

 a fresh state, showed the following colors: membrane of pectoral
