EL. Agassiz on Fishes of the Tennessee River. 353 
Arr. XXX VIIL.—WNobtice of a collection of Fishes from the south- 
ern bend of the Tennessee River, in the State of Alubama ; 
by L. Agassiz 
(Concluded from page 308.) 
CYPRINODONTS, Agass. —Only two species of this family 
have thus far been discovered in the waters of the ennessee 
River, and both of them have already been described by Dr. Sto- 
rer under the names of Pecilia catenata aud olivacea, Synopsis, 
-178. Having made lately however, a thorough revision of the 
getiera and species of this family found in the United States, I 
would remark that Pacilia cutenata, St., ought to be referred to 
the genus Hydrargyra, and that Pecilia olivacea belongs to my 
newly established genus Zyszonectes. ‘These species ought there- 
e to stand in future in our systematic catalogues under the 
names of Hydrargyra catenata, aud Zygonectes olivaceus.* 
CYPRINOIDS, Cuv.—This is one of the most interesting 
families of our fresh wraier fishes, both on account of the number 
of genera and species inhabiting our lakes and rivers, aud of the 
diversity of their forms and habits 
_Carrroves, Rafin.—In the great French Ichthyology, se 
ciennes has established a new genus me the name of Scler 
Snathus, for Lesnenr’s Catostomus cyprinus, and this genus aie 
deservedly been acknowledged by se tnathan writers. In con-
