Head4i; depth 4; eye 3; snout 3. D. 8; A. 8; scales 5-42-4. Body 

 elongate, compressed, the back somewhat elevated from the occiput to 

 base of dorsal, thence rapidly declined to the long and slender caudal 

 peduncle. Head short, compressed, the cheeks nearly vertical. Interor- 

 bital space rather broad and flat, somewhat grooved. Eye very large, 

 circular, high up, about 3 in head, nearly midway of length of head, its 

 diameter about equal to length of snout, scarcely greater than width of 

 interorbital space. Preorbital bone large, oblong, conspicuous, aud sil- 

 very. Mouth rather small, horizontal, the lower jaw included; edge of 

 premaxillary below level of eye ; maxillary not reaching to front of orbit. 

 Barbel conspicuous. Snout boldly and.abruptly decurved, much as in ff. 

 amhlops, the tip of the snout thickened, forming a sort of pad. Lateral 

 line somewhat decurved. Rows of scales along back converging behind 

 dorsal, where the upper series run out, as in Xoh-opis cornutus. Fins 

 rather higher and more falcate than in H. kentuckiensis; dorsal fin inserted 

 well forward, over ventrals ; pectoral fins pointed, not reaching veutrals ; 

 ventrals not reaching vent ; caudal long, deeply forked. Teeth usually 

 1, 4-4, 0, hooked, without grinding surface. Translucent greenish above ;
