4^ in the total. Body elongate, compressed ; its height is 

 hardly equal to the length of the postrostral portion of the 

 head. 



Snout broad, inflated, ohtusely pointed ; its length, which 

 is one fifth that of the head, is twice that of the small sunken 

 eye and barely equal to the width of the convex, pitted, inter- 

 orbital space. Nostrils adjacent to the eye. 



Mouth wide, oblique, with the jaws exactly conterminous 

 in front; the maxilla, which is half as long as the head, is 

 much expanded behind. Villiform teeth in the upper jaw

 teeth in the lower jaw. 



Gill-opening very wide ; gill-covers much expanded ; 

 operculum with a long spine ; gill-rakers ^q\\^ small. Scales 

 small, smooth, rather deciduous, covering the body and the 

 preopercular region. Lateral line apparently ending in the 

 anterior half of the body. 



Dorsal and anal fins enveloped in thick skin ; the dorsal 

 begins in the vertical through the middle of the pectorals, 

 the anal just in front of the vertical through the middle of 

 the body. Caudal entirely free. Pectorals broad, truncated, 

 half as long as the head. Ventrals uniradial, nearly as long 

 as the head.

 pp. 280, 281, pi. xviii. iig. 2. 



This species appears to be very common off the Ganjam 

 coast in 25 to 35 fathoms. The elongation of the anterior 

 rays of the dorsal fin is a secondary sexual character displayed 

 by the adult males alone.
