The pre-orbital processes, which are bluntly pointed depressed and 

 hollow — their cavity opening below by several large pores — are in 

 length nearly half the distance between their tip and the anterior 

 boi'der of the orbit, and each has upon its base a small upstanding 

 hook. 



The pre-opercular ridge is remarkably salient but is sharply trunca- 

 ted, not forming a spine. The opercular ridge forms a short bluntly 

 rounded spine. 



The lower jaw is thickly fringed with small tentacles. The labial 

 tentacles when laid back hardly surpass the angle of the mouth. 



The interorbital space, the breadth of which is equal to the major 

 diameter of the orbit, is deeply concave, and is ti-aversed fore and aft 

 by a deep median groove. Each supra-orbital margin is surmounted 

 posteriorly by a strong recurved spine, and there is a similar spine 

 on each side of the occiput. 



The body-shields are in four rows on each side : each shield is 

 strongly carinated, the carina being produced behind into a strong 

 spine ; and in the case of the shields of the posterior third of the 

 lateral line the carinje are slightly produced and pointed in front 

 also. 



The length of the anterior ventral shields is more than twice their 

 greatest breadth. 



Colours in spirit : body flesh-coloured ; the pectorals with a broad 

 jet-black band in their posterior half and with a milk white tip ; the 

 spinous dorsal black in its upper half, and the soft dorsal with a black 

 edge. 



Length 3*5 inches.
