This species is rather uncommon in our markets, and those 

 obtained at the above named stations were for the most part half- 

 grown specimens. Most of the areas on which they were taken 

 were sandy ; this would indicate that the species is not so wedded 

 to rocky situations as has been imagined. It was only gleaned 

 in deep water, the least depth being 41 and the greatest 80 

 fathoms. Although lines were put down on many of the recog- 

 nised Schnapper-reefs, it was never hooked.

B. vii. D. xii. 1/9. A. iii. 5. V. i. 5. P. 13-7. C. 14. L. lat. 38. 



L. tr. 5-32. 



Length of head 2-18, height of body 2-45 in the total length 

 (caudal excluded). 



Diameter of eye 3*33, length of snout 3-8, and interorbital 

 space, deeply concave, 4 "4 in the length of the head. 



Nostrils separated, in a naked area, the anterior surrounded by a 

 low fleshy rim with a tentacle behind ; posterior nostril simple. 

 Upper jaw in front, concave, a tubercle at the symphysis of the lower 

 jaw. Cleft of mouth wide and rather oblique, the maxilla reaching 

 to below the posterior fourth of the orbit. The internasal space is 

 concave and is surmounted on each side, near the anterior nostril, 

 by a simple spine. At the antero-superio angle of the eye is a 

 spine which may be simple, bifurcate or trifurcate; further back 

 towards the posterior angle, are three or four irregular spines, 

 all, however, arising from a common ba.se. On the occiput, mid
