part of the head. Coronet flat above, terminatiug behind in three 

 rounded denticulations, and in front, at its base, with four small 

 obtuse tubercles. A protuberance on each side of the head between 

 the coronet and the supi'aorbital ridge. Three protuberances below 

 the head, one median and two lateral. [This is not a specific cha- 

 racter.]

Dorsal fin with twenty (nineteen) rays. Eleven body-rings. 

 Tubercles not much developed, the coronet especially being very low, 

 though terminating in four or five small spines. The supraorbital 

 spine and that on each side of the throat are very similar in shape, 

 claw-shaped, acute, curved, bent backwards and inwards. Length 

 of the snout rather more than the distance between the hind 

 margin of the orbit and the gill-opening. Frequently three large 

 brown spots immediately below the dorsal profile, on the first, fourth, 

 and seventh body-rings.

Eleven body-rings. Dorsal fin with sixteen rays. Tubercles 

 rather prominent, hook-like, bent backwards. A pair of small, 

 erect, pointed spines in front of and inwards to the usual supra- 

 orbital spines, which are erect and slender. Coronet very low. 

 Snout rather longer than the distance between the hiud margin of 

 the orbit and the giU-opening.

a. Type of the species. From Dr. Cantor's Collection. 



The anterior supraorbital spines are altogether difi'crent in direc- 

 tion and form from those which arc sometimes found in s])ecimens 

 of other species, in whicli they are subject to variation, and of no 

 value for specific distinction.
