It is said by Mississippi River fish-ermen sometimes to reach a weight of 10 lb. It is sold for food, but CARPIODES—CARP-SUCKERS 77 is flavorless and soft. It breeds in spring, but the time of spawningis not indicated by our notes.

This fish is closely related to C. difformis, from which it may bedistinguished by the more pointed snout, smaller eye, and more ro-bust, subfusiform body. It and the next species agree in the short-ness of the snout, 3$ to 4$ in head, and in the anterior position ofthe nostrils, and both are by these marks readily distinguishable,except in the case of very young specimens, from thompsoni andvelifer, in which species the snout is notably longer, 3 to 3£ inhead, and the nostrils are situated far back from the end of thesnout, the distance from the anterior nostril to the end of themuzzle being greater than the diameter of Fig. 1 CARPIODES DIFFORMIS Cope (blunt-nosed river carp) Cope, 1870, P.
