PISHES OF NEW YORK 237" 



here for the first time announced as a member of the New York 

 fauna, and the description leaves no doubt of the correctness of 

 the identification. The fish examined, a female with ripe eggs, 

 was taken in Canandaigua lake, Dec. 19, 1896, by Mr Annin's 

 men. It was the only one caught, and was captured by becom- 

 ing gilled in the funnel of the net. Mr Annin is satisfied that, 

 this is the lake shiner of the fishermen, which they sometimes 

 see in immense schools at the surface, and kill for trolling bait 

 by shooting them.
