D.313- 514; Aso —-205 (Re naas NG 265 Vaal a Ao: 
Height 4 or somewhat more, head about 4, eye 2?/, to 
nearly 3, snout very short, less than '/, of eye, end of upper 
jaw slightly dilated, reaching not far behind posterior border 
of eye. Origin of dorsal before middle of length, somewhat 
behind origin of ventrals, ending slightly before origin of anal. 
Adipose fin above end of anal. Pectorals somewhat below 
middle of height of body, nearly reaching to vent. Caudal 
forked. Scales large, ctenoid, with many fine teeth, those of 
the ventral scales are large and few in number. Luminous 
organs: A small dorsal and ventral organ at the front margin of 
the orbit, two operculars, the larger dorsal one below the level of 
the ventral margin of eye, the smaller ventral one below it, on the 
level of the hindmargin of the upper jaw; 3 branchiostegals. 
Of the 5 PO between isthmus and ventrals, the 3 posterior 
ones are equidistant, but somewhat separate of the two an- 
terior ones. The posterior PVO below lower base of pectoral, 
obliquely before and below it the anterior one, which lies 
above the second PO. PLO above the anterior PVO nearer 
to base of pectoral than to lateral line. 4 VO, equidistant 
in a series between ventral and anus. 12—15 AO in two 
groups, in the anterior 6--8 above the anterior ?/, of the 
anal, in the second group 5—7, the two anterior of which lie 
above the end of the anal. The two Pre far distant from the 
AO, a little obliquely arranged. VLO nearer to lateral line 
than to ventral fin. The 3 SAO in an oblique or very slightly 
concave line; the inferior one above the space between the 
third and fourth VO, the middle one above the last VO, 
the upper and more distant one just below the lateral line in 
the vertical through the end of the dorsal. Pol slightly below 
the lateral line, above last AO of the anterior group. About 
7 supracaudal and 3 infracaudal luminous patches. Colour dark 
blue above, silvery below. Length nearly 90 mm. 
Habitat: Celebes Sea (surface)!; Ombai straits. — Indic. 
West Pacific and East Atlantic.
