We have met with a few specimens of this species in the 
Mahoning, a tributary of the Ohio River, and have also re- 
ceived specimens, from the upper lakes, through the politeness 
of Elisha Staling, Jr., of Cleveland. As it is figured and de- 
scribed, by Mr. Ayres, in Vol. V. of this Journal, it is only 
necessary to allude to it as one of The Fishes of Lake Erie. 
and the Ohio River, and their Tributaries. 
The series of descriptions of the Fishes of the Ohio and 
its Tributaries being now brought to a close, the following 
synopsis of the families, genera and species is appended. 
Besides answering as a catalogue of these fishes, so far as at 
present known, it will serve as an index to the volume and 
page of the Journal, where the description of each may be 
found ; thus abridging the labors of the student who might 
otherwise be obliged to extend his search through eleven 
different numbers of the Journal.
