behind end of dorsal, before the beginning of last '/, of length, 
ending below adipose fin. Pectorals somewhat below middle 
of height, reaching on ventrals, Scales cycloid. Luminous organs 
divided by a black septum. A minute antorbital organ dorsally 
at the frontborder of the orbit; two operculars, the larger 
dorsal one somewhat below level of ventral margin of eye, the 
smaller lower one behind upper jaw. 3 branchiostegals. 5 PO, the 
3 anterior ventrally in a series, the fourth quite outside the 
series above the third, the fifth lower down at the base of 
the ventral. The 2 PVO in a straight line above each other, 
the dorsal one about before the middle of the base of the 
pectoral, the ventral one nearly on the same level as the superior 
opercular and the fourth PO. PLO above and slightly before 
them, near lateral line. 5 VO between ventrals and anal, the 
second of them somewhat higher than the others, outside the 
series. 7 AO in two groups, the anterior group, above the 
anal, contains 5, the posterior group, far distant from the anal, 
contains 2 organs, the last of which is situated above the 
infracaudal luminous patch. 4 Pre, 3 anterior equidistant in 
a series behind that luminous patch, the fourth far distant in 
the end of the lateral line. VLO midway between ventral 
and lateral line. 3 SAO in an oblique line, with a shallow 
concavity looking forward, the lower one above the anus, quite 
near to it, above and somewhat behind it, the middle one, the 
uppermost more distant, near the lateral line. Pol near the 
lateral line between the anterior and posterior AO. A large 
supracaudal luminous patch above the infracaudal patch. Length 
153 mm. [After Brauer, not seen by us]. 
Habitat: West Coast of Sumatra (614 M.). — Indic be- 
tween Seychelles and Chagos archipelago. Pacific: Galapagos 
islands. 
We are not sure that Brauer’s indic specimens are identical 
with Garman’s JZ. lwminosum from Galapagos islands, as Garman 
counts D. 16; L.1l. 35 and does not mention the posterior 
AO and the 3 anterior Pre. 
5- Neoscopelus Johnson. 
(JoHNson, Proc. Zool. Soc. London, 1863, p. 44). 
Subfusiform, rather robust. Scales cycloid, deciduous, their 
surface finely denticulated. Lateral line present. Head conical.
