D. Ill, 30, I, first branched ray 1 2/3? in head; adipose fin 
5 1/5; A. Ill, 16, I, first branched ray 1 2/3?; caudal 1 1/5?. forked; 
least depth of caudal peduncle 2 3/4; pectoral 2 2/5?; ventral 1 4/5? 
Brown, nearly uniform. Iris gray, with pale luminous areas. 
Fins pale or whitish. 
Diagnosis. Related to Lampanyctus elongatus but distinguished chiefly 
by the higher supraventral photophore and the first supraanal separated 
from the fifth or last ventral by a scale width. 
The accompanying figure is based on a paratype originally evidently 
in Gilberts possession and not now in the collection of the United 
States National Museum or returned from Stanford University Museum.. 
According to the scale length given it is a much smaller specimen than 
the type. Most of the details set forth have been verified in comparison.

Collection (2528). Length 48 mm. Though in poor preservation I have 
been able to ascertain that the supraventral photophore is above the 
middle of the space between the lateral line and the ventral fin origin. 
The present specimen may therefore be regarded as a paratype.
