emargination of the operculum previously pointed out, enables me to 
define the genera more satisfactorily than my predecessors. Thus they 
may be arranged in groups. 
I. Operculum emarginate ; a supernumerary maxillary bone ;—Microp- 
terus, Ambloplites, Pomoxys, Centrarchus, Acantharchus, Enneacanthus 
(?) Hemioplites. 
II. Operculum emarginated; no supernumerary maxillary :—Meso- 
gonistius. 
III. Operculum entire, produced ; an additional bone attached to the 
maxillary :—Chenobryttus. 
IV. Operculum as last; no supernumerary maxillary :—Lepomis, 
Pomotis. 
21. CH&NOBRYTTUS GILLI, Cope. 
Lepomis gillit, Cope. Jour. Acad. Nat. Sci., 1868, 225. 
This species is exceedingly common in all the streams of North Caro- 
lina east of the Allegheny Mountains. It does not occur in the French 
Broad. All the specimens have clouded markings on the sides, which in 
the young, are broad, distinct olive-brown cross-bands, which embrace 
pale spots, giving a chain-like pattern. Fins blackish, cross-barred ;- four 
brown bands radiating backwards from orbit. Iris bright red. The spe- 
cies is rarely seen more than five inches long, and prefers rather still 
waters. It bites the hook very readily, and is called the red-eyed bream 
on the Catawba. 
The C. mineopas, Cope, possesses the additional maxillary, and I have 
no doubt the C. melunops (Gill’s type), and the C. charybdis, Cope, though 
I have not been able to verify it on the latter. 
ENNEACANTHOS, Gill. 
Jour, A. N. Sci., Phil., 1868, 218. 
22. ENNEACANTHUS GUTTATUS, Morris. 
Proceed. Acad. Nat. Sci., Phila., 1858, p. 3. 
Abundant in the Neuse River in still water, as in Virginia and New 
Jersey. 
LEPOMIS, Raf. 
23. LEPOMIS RUBRICAUDA, Holbr. 
This marked species, the southern representative of the L. appendia, 
is very common in the hydrographic basins of the Catawba, Yadkin and 
Neuse. In life the second dorsal and caudal fins are red, and there is a bay 
spot at the base of cach scale forming interrupted stripes. Flap of oper- 
culum black, the continuation of a dark shade from the preoperculum, 
which is bordered above and below by a blue band; two blue lines on 
operculum below the latter. 
24, LEPOMIS MEGALOTIS, Raf. 
L. incisor Cuv. Val. 
From the upper waters of the French Broad.
