FISHES OF NEW YOEK 73 



This fish seldom exceeds 3 feet in length. Its habits are pre- 

 sumably the same as those of the long-nosed gar, and it is 

 equally worthless for food. It may be readily distinguished 

 from the long-nosed species by the shape of its snout and by its 

 more robust form. 



The short-nosed gar inhabits the Great lakes and the Ohio 

 and Mississippi valleys. It is more abundant in the southern 

 part of its habitat. It was not recorded from waters of New 

 York by either Mitchill or De Kay.
