A REVIEW OF THE CENTRARCHIDiE. 
563 
Etymology : Latin ; big mouthed. 
I have been unable to find any stable differences between the antis- 
tins of McKay and the gulosus of Cuv. and Val. The differences men- 
tioned in Jordan and Gilbert’s Synopsis gradually fade into each other, 
and all the many specimens of war-mouth examined doubtless belong 
to one species. The Pomotis palliclus of Agassiz, which has become the 
Lepomis lirus of McKay, I cannot identify, and I suggest that it may be 
the same as Chcenobryttus gulosus .
