CENTRARCHIDA. 2% 
me 21; eye moderate, as long as snout, rather smaller than opercular 
flap, about 44 in head. Mouth moderate, the lower jaw slightly longest, 
the maxillary reaching middie of eye, with a strong supplemental bone; 
snout short, projecting, an angle over eye. Gill-rakers very long; flap 
larger than in the other species of the genus. 
Seales on cheek in 7 rows ; on body 6-43-14. Mucous cavities strong. 
Dorsal spines short and strong, as long as from snout to middle of 
eye; soft dorsal high, soft anal higher, both largely scaly ; caudal fin 
emarginate; pectoral fins long, reaching anal. Dorsal X, 10. Anal 
TH, :9. 
Color in spirits uniform olive-green, paler lines along the rows of scales ; 
soft fins somewhat mottled, but no black blotch on dorsal or anal. 
This species bears much more resemblance to Lepiopomus and Xystro- 
plites than to its congeners. From A. cyanellus, it differs in the greater 
depth and compression of the body, in the longer spines, longer opercu- 
lar flap, smaller mouth, and larger scales. 
Type, two specimens about six inches long, in the Museum of the 
Philadelphia Academy of Natural Sciences, collected at Beaseley’s 
Point, New Jersey, by Dr. Leidy. 
21. ENNEACANTHUS PINNIGER, Gill & Jordan, sp. nov. 
A very handsome species, rather larger than any other of this genus, 
and with larger fins. 
Body rather short, deep, compressed, regularly ovate in form; the 
depth half the length (without caudal); the head one-third. Eye large, 
34 in head. Mouth rather small, very oblique, the maxillary reaching 
to just opposite the front of-the orbit. 
Dorsal spines rather long, the soft rays greatly elevated; in the male 
fish as long as the head, reaching, when depressed, to the middle of 
the caudal; in the female fish considerably shorter; anal spines long, 
not rapidly graduated, the longest soft rays as long as those of the 
dorsal. 
Ventral fins elongate; the filiform tips of the longest rays in the 
males reaching the first soft rays of the anal, the spines falling short 
of the anal spines. In the females, the ventral fins are shortened and 
scarcely reach the anal. Pectoral fins moderate, reaching the soft rays 
of the anal. Caudal fin elongate, nearly as long as head. Lateral line 
complete. 
The female fish has all of the fins very much less elevated, the
