Pomolohus pseudoharengus lacustris. A., 279. 



This species, although not a native of Cayuga Lake, is often 

 found in large numbers in its waters. The fishermen about 

 Ithaca know it by the name Saw-belly. 



It is thought to have been introduced into the lakes of Cen- 

 tral New York by the State Fish Commission. 



Large numbers are often found dead upon the shores of 

 Cayuga and Seneca Lakes. 



All specimens seen by me were small.
