distinguished by the equal development of, and the correspon- 
dence of, the regions of the body above and below the axis, 
while in the Percoids and others, these regions are obliquely 
opposed. It is therefore probable that future investigation wi 
place the family on a firm basis. The family itself is composed 
of two very distinct types which must be regarded as subfami- 
lies; the Lepomin# distinguished by the very much greater 
development of the dorsal than the anal fin, their termination 
at the same vertical behind, and the equality of their respective 
soft portions; the EUCENTRARCHIN#, in which the dorsal and 
anal fins are nearly or quite equal and obliquely opposed, so that 
the end of the anal is considerably behind the vertical from that 
of the dorsal ; the soft portion of the anal is longest. These two 
subfamilies embrace a number of genera; Dr. Holbrook has ad- 
mitted “ Pomotis, Ichthelis, Pomozis, Ambloplites, Catliurus LAsl) 
&c., Raf., Centrarchus and Bryttus.". The Pomotis cheetodon B 
obesus, Grd., Centrarchus pomotis, Bd., Ambloplites interruptus Gd., 
and Pomoxis hexacanthus Ag., are types of as many additional 
genera; that typified by Pomotis chaetodon may be called MESO- 
GONISTIUS on account of the peculiar angulation at the dorsa 
spine; P. obesus (n. g. ENNEACANTHUS) is distinguished by the 
nine spines of the dorsal fin; Centrarchus pomotis ANTHAR: | 
cHus), by the elliptical form, cycloid scales and convex caudal; 
the Ambloplites interruptus has been already separated under the
