Body moderately elongate. Hearl moderate, the snout short and 
strongly convex, so that the mouth is nearly horizontal, the upper lip 
being below the level of the eye, lower jaw shorter than upper, max- 
illary extending beyond front of eye. Dorsal directly over ventrals, 
nearer snout than caudal. Scales deeper thau long, lateral line de- 
curved. Head 4^; depth 4^. 1). 8 ; A. 7 ; scales 6-40 f-.3. L. 3.^ inches.

“ Teeth 2, 4-4, 2, with sharp, serrate edges (without grinding surface). 
Dorsal fin inserted 2 scales behind that above insertion of the ventrals. 
Dorsal line compressed, elevated, rising regularly from end of muzzle. 
Cranium convex above. Muzzle narrowed in proportion, slightly over- 
hanging mouth. Eye 4^ in length of head, 1.4 in length of muzzle, aud 
2 in interorbital width. End ot maxillary opposite posterior margin of 
nares. Ventral outline less curved than dorsal. Caudal peduncle 
rather stout. Isthmus narrow. Scales rather elevated, 8-39-3. Lat- 
eral line gently decurved over ventrals. Head 4^ in length to origin of 
caudal, I scale less than depth at dorsal. The pectorals nearly reach 
the ventrals, and the latter attain the vent. Radii : D. 8 ; A. 8 ; the 
longest (anal) ray four thhds its base and three-sevenths distance to 
longest fulcrum at origin of caudal. Total length 44 inches. Color 
bright olive above, without line or spot; below anti sides, from fifth row 
of scales above, golden silvery; all the fins, except the pectorals, with 
white pigment at their bases, without markings ; a large, round black 
spot at base of caudal.” Pearl River, Mississippi. [Cope.) The num- 
ber of teeth in the inner row as above described renders it necessary 
for us to refer this fish to the genus Minnilm. Its affinities, however, 
are evidently with Gliola^ and the recorded dentition may be abnormaL

Teeth uot serrate; scales loosely imbricated, scarcely higher thaa loug.
