Lateral line with a semi-circular curve above the pectoral. Fins. 

 The dorsal fin begins in front of the anterior nostril and extends exactly 

 up to the base of the caudal : its first six rays are prolonged, the longest 

 being more than halt the total length of the body. The anal is 

 separated from the ventral by a median double-toothed sjiine, and 

 extends exactly up to the base of the caudal : its rays are similar to the 

 posterior rays of the dorsal. The caudal consists of 17 branched rays, 

 of which the longest are one-sixth the total length of the body : it is 

 obtusely pointed. The pectoral is much more developed ou the coloui-ed 

 side, where it is as long as the head exclusive of the snout, and consists 

 of 9 rays : the right pectoral is one-third less than the left in length, and 

 consists of 6 rays. The ventrals are both well developed, and both co- 

 loured : the left has 6 rays arranged in a line from the tliroat to the 

 anal, the right is of the usual form. 



Colours in life, dull smoky brown with a circumferential row of 

 ill-defined dark blotches just inside the vertical flas, and others along 

 the lateral line. Both ventrals nearly black. Coloured pectoral with a 

 transverse black band in its posterior half. 



Total length inches. 



Locality of capture, 5 miles south of Ganjam in 25 fathoms, on a 

 clean sandy bottom. Only one specimen.

B. 6. D. 68-G!*. A. 44-46. L. lat. 30. 

 Body rather elongate, its height being one-third of the total length. 

 The length of the head is one-fourth of the total and equal to its height. 

 The lower jaw j)rojeots and forms the tip of the snout, and there is a 

 sharp knob at the symphysis. The snout is poiuted and is as long as 

 the eye. Eyes on the right side, large, being one-fourth of the head- 

 length in diameter ; they are separated by a shai'p ridge ; the upper is 

 in advance and is very oblique. Nostrils in front of the interorbital 

 space, the anterior being valved : ou the left side they are very incon- 

 spicuous and are placed almost on the dorsal profile. Mouth wide and 

 forming an almost vertical arch : the maxilla extends behind the level 

 of the lower mid-orbit and is slightly over half the length of the head. 

 Numerous close-set, pointed, conical, curved teeth in both jaws and on 

 the strongly projecting head of the vomer : those in the premaxilla are 

 arranged in a double series anteriorly, and tliose in the loioer jaw are in 

 a double series throughout, the inner row being incurved, while at the 

 symphysis they are in a thick patch. Gill-cleft very wide. Margin of 

 the opercle trilobed. Gill-rakers few, distant, lanceolate and coarsely 

 seriated ou their upper suri'iioo. lutegumout covered with large, thia
