It is sold for food, but is flavorless and soft. It breeds in spring, 

 but the time of spawning is not indicated by our notes. 



This fish is closely related to C. diffonnis, from which it may 

 be distinguished by the more pointed snout, smaller eye, and 

 more robust, subfusiform body. It and the next species agree 

 in the shortness of the snout, 33/3 to 43/2 i^i head, and in the an- 

 terior position of the nostrils, and both are hj these marks 

 readily distinguishable, except in the case of very young speci- 

 mens, from tho7npso7ii and velifer, in which species the snout is 

 notably longer, 3 to 33/2 '^^ head, and the nostrils are situated 

 far back from the end of the snout, the distance from the anterior 

 nostril to the end of the muzzle being greater than the diameter 

 of the eve.
