portion being scarcely half as long as the head. There are two and 

 a half (?) series of scales between the lateral line and the root of the 

 ventral fin. Lips without lobcb ; mouth anterior. The height of 

 the body is two-ninths of the total length (without caudal), the 

 length of the head one-fourth. Head elongate, snout produced. 

 The origin of the dorsal fin is before the vertical from the base of 

 the ventrals, and nearer to the end of the snout than to the base of 

 the caudal. Caudal fin forked. {Rupp.)

The osseous dorsal ray is strong, smooth, its stiff" portion being 

 about three-fourths as long as the head. There are two and a half 

 series of scales between the lateral line and the root of the ventral 

 fin. The length of the head is two-ninths of the total (without 

 caudal). Snout moderately produced, somewhat pointed ; mouth 

 inferior ; lips not thickened, without lobes. Body moderately elon- 

 gated, somewhat elevated below the origin of the dorsal, its greatest 

 depth being two-sevenths of the total (without caudal). The origin 

 of the dorsal fin is nearly opposite that of the ventral, and a little 

 nearer the end of the snout than the root of the caudal. Caudal 

 fin deeply forked. {Rilpp.)

The osseous dorsal ray is moderately strong, smooth, its stiff" por- 

 tion being not quite half as long as the head. There are three (?) 

 series of scales between the lateral line and the root of the ventral 

 fin. The length of the head is contained thrice and one-third in 

 the total (without caudal) ; snout produced, with the cleft of the 

 mouth wide*; mouth anterior, lips without lobes. Eye small. 

 Body elongate, its height being two-ninths of the total length (with- 

 out caudal). The origin of the dorsal fin is opposite the root of the 

 ventrals, and nearer to the root of the caudal than to the end of 

 the snout. Caudal fin deeply forked. {Bupp.)
