Three lateral lines on the left side, the upper and lower separated 

 from the middle by seventeen or eighteen series of scales ; one on the 

 right side. Two nostrils : one between the eyes, and the other above 

 the cleft of the mouth. Eyes subcontiguous ; lips hot fringed. The 

 angle of the mouth is rather nearer to the gill-opening than to the 

 extremity of the snout ; the rostral hook terminates in the vertical 

 from the front margin of the eye. The height of the body is con- 

 tained four times and a third in the total length, the length of the 

 head five times. Brownish, with irregular darker spots.

One lateral line on the right side, three on the left : the dorsal and 

 ventral lines separated from the middle by about nineteen longi- 

 tudinal series of scales, when counted at the end of the abdominal 

 cavity. Only one ventral is present, united with the anal. Two 

 nostrils : one between the eyes, and the other before the lower ang:le 

 of the lower eye. The upper eye is slightly in advance of the lower ; 

 the width of the interorbital space is rather more than that of the 

 orbit. Lips not fringed. The length of the snout is one-third of that 

 of the head. The rostral hook terminates behind the symphysis of 

 the mandibles. The height of the body is contained thrice and 

 three-fourths in the total length, the length of the head four times 

 and two-thirds, Brown ; fins blackish, edged with white.

 Three lateral Knes on the left side ; when counted at the end of 

 the abdominal cavity, the upper line is separated from the middle by 

 twenty-one longitudinal series of scales, the middle from the lower 

 by twenty-four. One lateral line on the right side. One ventral, 

 united with the anal. Two nostrils : one anteriorly between the 

 eyes, the other before the lower angle of the lower orbit. The upper 

 eye is slightly in advance of the lower ; the width of the interorbital 

 space is rather less than the diameter of the eye, which is one-
