D. IV. 9. A. 9. CIO. P. 21. V. I..5. 



Length of tlie head nearly a third, height of the body about a ninth of the 

 total length without the caudal. Eyes as long as or a little longer than the 

 snout, one-fourth the length of the head ; separated by a very narrow bridge. 



Preopercular spine shorter than the eye ; its base is advanced forwards as 

 a sharp spine ; on its upper edge are two spinelets, the anterior of which is 

 very small. 



Gill-opening a small aperture, not half the diameter of the eye, on the 

 upper side of the neck. 



Lateral line single. 



The anterior dorsal spine is prolonged, especially in the male, in which sex 

 it is not much shorter than the head. The rays of the second dorsal fin, in 

 both sexes, are as long as the postorbital portion of the head. The middle 

 caudal rays are prolonged in both sexes, being between a third and a fourth the 

 total length (caudal included). 



The ventrals are a little longer than the pectorals ; in the female, but not 

 in the male, they reach beyond the origin of the anal. 



Anal papilla large in the male. 



Colours : reddish, with irregular large rounded violet spots along the 

 middle of the body : a lunate black spot, in both sexes, between the 3rd and 4th 

 dorsal spines ; second dorsal with a series of large subocellated bands, which 

 are very conspicuous in the male. 



Two specimens, adult male and female, from off the Malabar coast 102 

 fathoms. The male is 7 inches long.

Distribution : Sea of New Guinea : Arabian Sea. 



A large number of young, which may perhaps belong to this species, were 

 taken off the Malabar coast in 56 to 58 fathoms. 



Suborder Anacanthini. 



An acanthini Gadoidei. 



The Gadoidei of the Fauna of British India, include two families (Gadidx 

 and Ophidiidse), three genera exclusive of Ammodytes, and five species only. 



To these we have now to add two families {Macnirida^. and Ateleopodidx), 

 seventeen genera, and forty-four species, all of which have been brought to light 

 by the dredge of the " Investigator."
