Chrosomus seca Raf.—It is one of the prettiest po 
water fishes of North America, varying greatly with age an 
different periods of the year. It remains yet to be i eer 
whether the specimens from the Tennessee River are strictly 
identical with those from the Ohio River. I have received speci- 
mens from the Osage River, from Mr. G. Stolley, which differ

‘orm. 
Stix, DeKay.—In his Natural History of New York, DeKay 
has established this genus for the Cyprinus chrysoleucos of 
Mitchell. Without a thorough revision of the many new gevera 
of Cyprinoids established by Heckel and Prince Canino, for 
Which I have not the necessary materials on hand, I am unable to 
decide whether DeKay’s genus may stand or not. "So much how-
