Distinguished from the other sucker by having a longer head and nose and 

 finer scales. Specimens from First Connecticut Lake i*ange in length from 3.75 

 to 5.37 inches, with an average of about 4.62 inches. 



This northern sucker was described from Vermont by Le Sueur as 

 Catostomus longirosttis. Forster first records it from Canada as 

 Cyprhms catostomus. It is sometimes called " red sucker " and " red- 

 sided sucker," owing to the red or reddish stripe that is frequently 

 present along the side in the breeding season. It is also known as 

 " small scale sucker." It is found from New Brunswick and New 

 England westward to the Great Lakes, and northwestward to Alaska. 

 We collected it in Indian Stream, Perry Stream, streams connected 

 with First Connecticut Lake, and in Second Lake. The largest speci- 

 mens were found in Perry Stream, 



This species is regarded as a comparatively deep-water fish, seldom 

 entering shallow water except to breed or feed upon the eggs of other 

 fishes. In many waters it attains a much larger size than it does here. 

 There seem to be two distinct sizes of adult fish. The small one was 

 described by Mather " as Catostomus nanomyzon. The food of this
