rican and English species, I make use of the name chubsucker as more distinctive. It is 
common in many of our fresh-water streams, and usually appears in the markets in the month

This fish, which is commonly called Carp, in consequence of its resemblance to the carp 
of Europe, is common in the Susquehannah, and will probably be found in some of its sources 
within this State. Iam indebted to M. Lesueur for the figure and very brief description,
