290 REPORT OF NEW JERSEY STATE MUSEUM. 



Lips rather fleshy. Teeth pointed, in bands, and an outer en- 

 larged series in each jaw. A patch of small vomerine teeth, and 

 narrow series or band of smaller ones on palatines. Nostrils in 

 a slight depression, separated, posterior near front of eye about 

 level with upper rim of pupil, and anterior with a slight cutaneous 

 rim. Interorbital space a little convex and rather broad. Supra- 

 scapula entire. Opercle with a large flap about equal tO' orbit and 

 somewhat stiffened, so that the osseous portion is distinct from 

 the cutaneous rim, which is, however, very narrow, though of 

 about equal width. Margin of preopercle entire. Gill-opening 

 extending forward till about opposite anterior margin of orbit. 

 Rakers i 3 + 1 1 ii^ pointed, a little curved, and longest about 

 five-sixths of longest filaments, which are about four-sevenths of 

 orbit. Isthmus rather narrow, compressed, and with beveled edge. 

 Pharyngeal cavity already partly dissected and teeth similar to 

 those of Lepomis palladiis (Mitchill) as figured by Mr. Richard- 

 son,^ i. e., conical and pointed, though lower anterior ones more 

 or less rounded. Scales moderately small, rather broadly ex- 

 posed, in series parallel with lateral line above its course, though 

 in horizontal series below. Scales on head, chest and on and 

 along bases of fins smaller. Interorbital space, snout, jaws, mar- 

 gin of opercle, narrow ocular rim and branchiostegal region 

 naked, head otherwise scaly. Scales on cheeks small, in 6 series. 

 Opercular scales largest of scales on head. Scales along bases of 

 spinous dorsal and anal forming sheaths and those on soft fins 

 smaller, also extending well out between rays. Lateral line of 

 simple tubes, nearly concurrent with dorsal profile, extending a 

 little high on side of caudal peduncle at first, but not on base of 

 caudal. Origin of spinous dorsal a trifle behind that of pectoral, 

 margin of fin notched, spines low and graduated to fifth, after 

 which they are subequal and longer. Soft dorsal higher, inserted 

 about midway between origin of pectoral and base of caudal, and 

 graduated to seventh ray, which is longest. Spinous anal a little 

 nearer base of caudal than posterior margin of eye, margin 

 notched, spines low and graduated to third, which is longest.
