or slightly behind root of ventrals, its hindermost rays above 
foremost rays of anal. Adipose fin opposite to hindpart of 
anal. Pectorals nearly ?/, of length of head, not reaching 
middle of ventrals. Ventrals not reaching vent. Caudal forked. 
Scales cycloid, thin, not spinous, deciduous. Luminous organs: 
a minute round antorbital on the lower anterior orbital margin ; 
2 operculars, the larger dorsal one below the level of the 
ventral orbital margin, the smaller lower one behind angle of 
intermaxillary, partly covered by the margin of the prae- 
opercle. 3 branchiostegals. 5 PO in a straight series between 
isthmus and ventrals, the 3 anterior ones are more distant 
than the posterior ones. Of the 2 PVO the posterior is situated 
before the lower base of the pectoral, the anterior before and 
below it, above the second PO. PLO above the space 
between them, slightly below the lateral line. 4 VO in a 
straight line between ventrals and anus. Number of AO 
variable from 7 to 10 in the anterior group, which alone lies 
above the anal and 3—7 in the posterior group, which begins 
above the last anal ray or immediately behind the anal; the 
most frequent arrangement is after Brauer: 7 + (5—6), 8+ 5 
and g+ 5. The 2 Prec straightly or slightly obliquely behind 
each other. Arrangement and situation of the 3 SAO and of 
Pol as in punctatum. There may be a supra caudal luminous 
patch. Dusky brown above, silvery below, specked with brown. 
Fins translucent, base of caudal blackish. Length 80 mm.
