or slightly behind root of ventrals, its hindermost rays above 



foremost rays of anal. Adipose fin opposite to hindpart of 



anal. Pectorals nearly 2 / 3 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 -f- 5 



and 9 + 5. The 2 Prc 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.
