Dorsal and anal fins turned over posteriorly on the blind side of the 

 tail, where the last rays form a small flap. Ventrals disconnected from 

 the anal. The height of the body is nearly one-half of the total length 

 (without caudal), the length of the head two-sevenths. Scales small, 

 but very distinct, each with about four spines at its posterior margin ; 

 head and fin-rays entirely covered with minute rough scales. The 

 lateral line makes a subsemicircular curve above the pectoral. The 

 lower jaw ih slightly prominent ; the length of the maxillary is one- 

 half, or rather more than one-half, of that of the head. Snout obtuse, 

 longer than the eye, the diameter of which is one-sixth of the length of 

 the head. Eyes separated by a very narrow and elevated ridge, the 

 lower being a little in advance of the upper, and sometimes provided 

 with a slender tentacle. The dorsal fin commences a little before 

 the vertical from the front margin of the lower eye, and is continued 

 on to the root of the caudal. The first ray is produced into a fila- 

 ment, one-third as long as the head. The first dorsal ray is some- 

 times prolonged and filamentous. Gill-rakers rather widely set, half 

 as long as the eye. Brownish-grey, with blackish spots : one at the 

 end of the curve of the lateral line ; a reddish ocellus edged with 

 black on the middle of the tail.
