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 

 of December. It appears closely allied with the gibbosus of Lesueur, and also with the suc- 

 ceeding species.

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. I am indebted to M. Lesueur for the figure and very brief description.
