CYPRINIDiE. 175 



The branchial rays are three in number, the dorsal fin-rays twelve, 

 the pectorals twelve, the ventrals seven, the anal twenty-seven, and 

 the caudal nineteen. 



A little fish, closely resembling this in form, is described and figured 

 in Dr. Richardson's Northern Zoology, on the authority of Lieut. 

 Col. Smith, who took it at the confluence of the Richelieu and St. 

 Lawrence. It is known to the Canadians as la Quesche. In form, it 

 closely resembles this species ; and in color, the last described ; but 

 it has one spiny ray in the dorsal, and one in the anal fin, and a 

 toothed tongue, which would seem to divide it from the genus Ahra- 

 mis ; while the sizs of the anal divides it from the true Carps. It 

 has, moreover, small scales, and barbels.
