Catostomus nigricans Le Sueur. Black Sucker. 

 Bergen, Mercer (Carnegie Lake), and Morris Counties. The material 

 in the Academy was simply labeled New Jersey and likely came from 

 Morris County. Also in the same region I saw a single example in a 

 tributary of the Raritan east of Chester. Its rarity suggests the possi- 

 bility of introduction.

Moxostoma macrolpeidotum (Le Sueur). Red-horse. 



Though originally described from the Delaware by Le Sueur, where 

 apparently now rare, as I have not seen any examples. Eugene Smith re- 

 cords it doubtfully from the upper Passaic basin.
