in the total. Body elongate, compressed ; its height is 
hardly equal to the length of the postrostral portion of the 
head. 
Snout broad, inflated, obtusely 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 
and vomer and in a long row on the palatine ; caniniform 
teeth in the lower jaw. 
Gill-opening very wide ; gill-covers much expanded ; 
operculum with a long spine ; gill-rakers few, small. Scales 
small, smooth, rather deciduous, covering the body and the 
preopereular 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.

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.
