but one below it. Base of ventral distant from the anal one length of the 

 head, fin length four fifths of the distance from the anal, shape narrow, 

 pointed. Pectorals narrow, prolonged in a filament, total length less than 

 that of the head, inserted near the ventral surface. 



Light organs small, the largest being that between the eye and the 

 maxillary ; forty-nine in the humeral series, from the shoulder to the vent, 

 of these thirty-nine are forward of the ventrals ; seventy-six between the 

 isthmus and the caudal in the lower series, of which fifty-nine are forward 

 of the vent, forty-nine forward of the ventrals, and ten below the isthmus.

Moderatel)' elongate and compressed, depth about one ninth and length 

 of head nearl}- one sixth of the entire length. Mouth nearly as long as the 

 head, each intermaxillary with five unequal fang-like teeth, second longest. 

 Maxillary forming the edge of the mouth posteriorly, with denticulations. 

 Mandibles with about seven (7-9) longer teeth followed by denticles toward 

 the angle of the mouth. Vomer with a fang at each side of the forward 

 end. Each palatine wnth a fang behind the vomerine tooth. No teeth on 

 the tongue. Barbel as long as the lower jaws, distal third of the length 

 bifid in a pair of slender extremities, basal portion ending in a luminous 

 bulb. 



A series of forty-seven luminous facets extends from the shoulder to a 

 point above the vent; another series from the isthmus contains sixty-seven, 

 of which forty-eight are forward of the anal ; the series at the side of the 

 isthmus contains a dozen or more, and in each branchiostegal series there 

 are, sixteen. Besides the luminous spots in the regular series there are 

 many other smaller ones scattered over the body and the head. Most of 

 them are on the lower half, but in the six uppermost series of scale areas 

 there is generally a single spot on the middle of each scale, some have two 

 or more. On each of the hexations below the third series the dots are more
