The height of the body is contained once and four-fifths in the 

 length (without caudal), the length of the head thrice and two- 

 thirds. Eyes separated by a naked space, the width of which is 

 less than the vertical diameter of the eye ; the lower eye is slightly 

 in advance of the upper. Snout as long as the eye, the diameter 

 of which is one-fifth of the length of the head. The maxillary 

 on the right side extends to below the anterior margin of the eye ; 

 teeth in narrow bands. Jaws equal in front ; the upper lip has 

 a slight notch, in which the symphysis of the lower jaw is 

 received. The cutaneous fold above the maxillary is not prolonged. 

 The gill-opening does not extend upwards beyond the base of the 

 pectorals. The dorsal fin commences on the foremost part of the 

 snout, and terminates at a distance from the caudal, which is 

 rather more than half the depth of the free portion of the tail ; 

 the anterior dorsal rays produced beyond the connecting membrane 

 but considerably shorter than those behind the middle of the fin, 

 which are nearly half the length of the head. Caudal fin, slightly 

 rounded, one sixth of the total length. The six ventral rays are 

 arranged in the same line with those of the anal fin, both fins 

 being connected by a broad, complete, rayless membrane ; the 

 vent is situated on the blind side. The length of the pectoral is 

 two-thirds of that of the head. Uniform brownish (in spirits) ; 

 pectorals blackish posteriorly.
