of the Bay of Bengal. 
The dorsal fin commences on the blind side of the snout in 
front of the level of the eye, its longest rays (just behind the 
middle of the fin) are not quite half the length of the head 
and are slightly shorter than the corresponding anal rays. 
The pectoral fin is more developed on the coloured side, 
where, if laid forward, it reaches to the posterior border of 
the lower (anterior) orbit. Ventrals six-rayed, the left wider 
than the right. Caudal pointed, with 17 rays, its length 
nearly one fifth of the total. 
Colours in the fresh state : — Left side dark sepia ; vertical 
fins and left ventral black; left pectoral grey in its basal 
third, black in its distal two thirds ; branchiostegal fringe on 
the left side black, right side unpigmented. 
Originally obtained in 100 fathoms, 40 miles S.W. of 
Akyab; now from Station 96, where eleven specimens (the 
lougest 4f inches) were taken.

• Several hundred specimens were taken at Station 96 (98- 
102 fathoms), many of them being mature females. The 
general facies of this fish is certainly bathybial.

Body compressed, with the posterior half much lower than 
the anterior; its greatest height just over one fourth of the 
total without the caudal, its least height, midway between the 
adipose dorsal and the base of the caudal, one third its greatest 
height at the shoulder. 
Head large, its length a little more than one third the total 
without the caudal, its height two thirds its length. Snout 
obtuse, symmetrically rounded, its depth more than three 
times its length, which is less than half the diameter of the 
eye. Eye circular, moderately large, its diameter being one 
third the length of the head ; the posterior border of the orbit 
is half an eye-diameter distant from the vertical border of the 
preoperculum; no spine above the orbit; interorbital space
