Scalessomewhat smaller and more closely imbricated than in the two pre-ceding species, 7, 38 to 40, 6, usually 39 in longitudinal series; lateralline complete, nearly straight. <~*. This species can be separated with readiness from both the pre-ceding by its longer nose, more oblique mouth, and more posteriornostrils; it is from the next when adult by itslarger size and by the differences in general proportions, and by theshortness of the first dorsal rays. The ycrung of these two speciescan not be separated with any certainty. This carp-sucker belongs to the fauna of the Great Lake regionand is but rarely taken in the inland waters of Illinois, our adultspecimens numbering a very few from the Illinois river at Ottawa,Henry, Havana, and Meredosia. It is too rare in our waters to becommercially important. Its special habits are unknown.
