IGO TTJRBOT. 



spine coverins; a portion of the upper jaw; under jaw longest; 

 teeth placed thickly in several rows, and a row also in the 

 palate. Lateral line arched over the pectoral fin, and thence 

 straight to the tail; upper or coloured side without scales, but 

 irregularly covered with stout bony tubercles; on the mystachc, 

 round the eyes and the gill-covers, are thickly-set small bossed 

 points. The tubercles on the body have not yet appeared in 

 very young examples, and they appear to be less in number 

 in examples which seemed to be of advanced age. The 

 dorsal fin begins in front of the eyes, and, with the anal, 

 passes on close to the tail; the tail round. Ventral fins close 

 under the tliroat, and nearly joined to the anal. The hindmost 

 nasal orifice on the blind side, bordered posteriorly with a 

 loose membrane. The colour varies in intensity, from light 

 brown to almost black; and in an example that was intensely 

 black, both sides were alike coloured, mottled and sprinkled 

 over with dots of darker and white, as if with sand. The fin 

 rays are wide: in the dorsal sixty-eight; anal forty-eight to 

 fifty -nine; pectoral ten; caudal fifteen to seventeen; ventrals 

 five on the coloured side, six below, the first of the latter 

 answering to the second above.
