480 Fishes of the Ohio 
Observations. 'The upper part of the pharynx is 
armed with two elongated bony plates; which are 
adapted to the bony armature of the branchial rays 
in such a manner as to enable the fish to grind to 
pieces its food. The alimentary canal from the pha- 
rynx to the vent does not exceed the whole length 
of the fish itself. Its natatory bladder is cellular, like 
the lung of a reptile. In the stomach of one I dis- 
sected, were found the remains of a number of craw- 
fish. Richardson, in the “ Fauna Boreali-America- 
na,” describes a species taken in Lake Huron, which 
he calls A. ocellicauda. This northern species I be- 
lieve to be specifically identical with the A. calva, as 
his description agrees with the description of that 
fish ; and I have traced its residence in all the waters 
from Lake Erie, south to the Mississippi, and thence 
to the waters of South Carolina, whence Linneus 
obtained his specimen.
