Head much compressed squarish, its length, which is not much more than 

 its height, is from a sixth to a seventh of the total, without the caudal. Eye 

 circular, about as long as the snout proper, between a third and a fourth the 

 length of the head. Lower jaw prominent beyond the snout. 



The dorsal fin begins less than a head-length behind the occiput ; the 

 filamentous first ray is from twice the length of the head to more than half the 

 body in length. 



The longest ventral rays are nearly twice as long as the pectorals and about 

 a third as long again as the head. 



Scales hexagonal. The luminous organs are disposed, on each , side, as 

 follows, and are conspicuous : — 



(1) a aeries between the bases of the branchiostegals : 



(2) a series of 61 in a lower tier from the chin to the caudal, of which 30 

 are between the chin and the ventrals : 



(3) a series of 38 between the base of the pectoral and the anus, of which 

 17 are between the base of the pectoral and the base of the ventral. 



(4) one below the eye, and (5) one in the upper part of the suboperculum. 

 Besides these there are countless tiny spots, in rows and clusters, all along 



the abdominal line from the chin to the caudal. 



Colours in spirit, silvery more or less ; fins white. 



A ripe female in the Indian Museum is six inches long, but there is a muti- 

 lated specimen much longer.
