of the Day of Bengal . 217 



The dorsal fiu 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 tin 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 

 Akj'-ab ; now from Station 96, where eleven specimens (the 

 longest 4| inches) were taken.

Several hundred specimens were taken at Station 96 (98- 

 102 fathoms), many of them being mature females. The 

 general /a cz'es of this fish is certainly bathybial.

D. 11-12. A. 17. L. lat. circ. 30. P. 15. V. 8. 



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 tliree 

 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 j interorbital space
