D. 8. A. 17. 



Barbels four, the upper of which are small, the lower somewhat 

 louger than the head. The height of the body is nearly equal to 

 the length of the head, and rather more than one-fourth of the total 

 (without caudal). Lower jaw projecting beyond the upper. The 

 lateral line is scarcely observable. Sides with eight or nine alter- 

 nate longituchnal stripes of blue and silver ; several similar stripes 

 on the caudal and anal.

Barbels none. The height of the body is a little less than the 

 length of the head, which is contained four times and one-fourth in 

 the total (without caudal). Mouth rather wide, the maxillary ex- 

 tending somewhat behind the front margin of the eye. The third 

 suborbital bone is a little broader than the soft naked portion of the 

 cheek. Dorsal fin not much higher than long, its last rays being 

 above the front part of the anal. Pectoral process of the humerus 

 not enlarged. Uniform silvery.

Barbels none. The height of the body is contained six times and 

 a half in the total length (without caudal), the length of the head 

 four times. Moutli of moderate width, the maxiUary not extending 

 to the vertical from the front margin of the orbit. Lower jaw pro- 

 jecting beyond the upper. Head twice as long as deep. Snout 

 conical, pointed, much longer than the eye, the diameter of which is 

 two-ninths of the length of the head. Suborbital ring much broader 

 than the soft naked portion of the check. Origin of the dorsal fin 

 nearer to the root of the caudal than to the gill-opening. Origin of 

 the anal opposite to the fifth dorsal i-ay. Pectoral rather more than
