The height of the body is contained twice and two-thirds to thrice 

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

 five times and a half. Scales small, not ciliated ; head entirely 

 covered with very smaU imbricate scales, snout and ridge between 

 the eyes naked ; body entirely smooth. Lateral line straight, with- 

 out curve. Snout rather shorter than the eye, the diameter of which 

 is one-fourth of the length of the head. Jaws subequal anteriorly, 

 maxiUary shorter than the eye. Upper jaw with a series of about 

 twenty closely-set, tmncated, incisor-like teeth on the blind side. 

 Eyes separated by a shai'p ridge, elevated in front of the lower eye; 

 the lower eye somewhat in advance of the other. The dorsal fin 

 commences above the middle of the eye, and its distance from the 

 caudal is rather less than one-half of the depth of the free portion of 

 the tail. Bands of small scales along each dorsal and anal ray. The 

 middle dorsal rays are the longest, a little more than half as long as 

 the head ; pectoral half as long as the head. No prominent spine 

 before the anal. Greyish-brown ; membranes of the fins with, dark 

 spots ; pectoral of the coloured side black.
