Dorsal fins separated by a snout-length, the second much the higher ; the 

 first has five stout sharp spines, the three anterior a little longer than the snout ; 

 the second has one short spine and ten branched rays, and is invested at its base 

 with scales. Anal with one spine and nine branched rays, situated opposite the 

 second dorsal, and similar to it in every respect. Caudal short, forked ; its 

 proximal half scaly. Pectorals well developed, as long as the head without the 

 snout. Ventrals thoracic, with one spine and five rays with scaly bases. 



No air-bladder. Long pyloric cseca in moderate number. Colours in life, 

 uniform jet-black.

D. XI. 1-9. A. III-5. Sc. circ. 53. 



Height of the body about one-third, length of the head nearly half, the 

 total length without the caudal. 



Snout produced, its length is not quite equal to the major diameter of the 

 eye, which is about two-sevenths the length of the head, and more than twice 

 the width of the inter-orbital space (in young specimens). 



Vertex of head with prominent spines and small scales and with three pairs 

 of simple tentacles of good length— one at the anterior angles of the orbits, 

 one above the middle of the eyes, and a third on the nape. (There are other 

 small tentacles along the preopercular stay and along the lateral line, but they 

 are liable to be lost by abrasion). 



Mouth-cleft wide, the maxilla reaching nearly to the middle of the eye. 

 Villiform teeth in the jaws, in a narrow band on the palatines, and in a V-shaped 

 patch on the vomer. Tongue free, pointed. 



The 3rd and 4th dorsal spines are the longest, about a third the length of 

 the head, and shorter than the 2nd of the anal. Pectoral fin reaching to the 

 anal.
