THE CORAL TRIANGLE: HEARST BIODIVERSITY EXPEDITION 
Remarks.— This specimen agi'ees relatively well with S. oculeus except for the dark peritoneum and the low 
LL-scale count (54—57 in S, oculeus). Whether these differences are of specific importance is not known. 
The two or three short stripes on the cheek and the large orbit otherwise appear to distinguish S. oculeus 
from other western Pacific members of the genus. 
Synodus sp. 
Material.— CAS 236478 (10, 35.3-42.6 mm SL); HEPD-026, beam trawl in 82-86 m. 
Remarks.— We were unable to identify these juvenile specimens. 
Chlorophthalmidae (Greeneyes) 
Chlorophthalmus acutifrons Hiyama, 1940 (Fig. 36) 
Material.— CAS 235821 (134 mm SL; DC-1566); HEPD-036, beam trawl in 216-262 m. 
Remarks. — This is a common species known from southern Japan, the East China Sea, Taiwan, and the 
Philippines in 260-435 m. 
Chlorophthalmus albatrossis Jordan and Starks, 1904 
Material.— (91 mm SL); HEPD-003, beam trawl in 272-291 m 
Ipnopidae (Grideye Spiderfishes) 
Bathypterois atricolor Alcock, 1896 (Fig. 37) 
Material.— CAS 2355479 and 236195 (2, 135-150 mm SL); HEPD-016, otter trawl in 892-966 m. 
Remarks. — This species is very similar to B. phenax from the Atlantic, and apparently differs only in the 
placement of its vertical fins. 
Bathypterois guentheri Garman, 1889 (Fig. 38) 
Material.— CAS235452 (2, 207-226 mm SL, DC-1399, -1400); HEPD-015, beam trawl in 757-836 m. 
Neoscopelidae (Blackchins) 
Neoscopelus microchir Matsubara, 1943 (Fig. 39) 
Material.— CAS 235378 (2, 114.5-115.0 mm SL) and CAS 235504 (4, 75.2-93.5 mm SL); HEPD-003, 
beam trawl in 272-291 m. CAS 236624 (11, 74.6-114.3 mm SL); and CAS 235506 (3, 83.0-116.0mm 
SL); HEPD-009, otter trawl in 322-336 m. 
Remarks.— We counted lateromedial photophores as 20-22 + 3 separated anteriorly over the pectoral-fin 
base, the series extending over the anal-fin base. Nafpaktitis (1977:9) gave counts of LO photophores that 
are low compai-ed with tliose of oui* material. His study material included many Philippine specimens. 
Neoscopelus porosus Arai, 1969 
Material.— CAS 233995 (11, 77-133.5 mm SL); HEPD-006, otter trawl in 454-457 m. CAS 235492 (139 
mm SL, DC-1571); HEPD-039, beam trawl in 633-642 m. 
Myctophidae (Lanternfishes) 
Benthosema fihulatum (Gilbert and Cramer, 1897) 
Material.— CAS 236518 (2, 56.5-57.0 mm SL; DC-1285); HEPD-004, otter trawl in 154-245 m. 
Remarks.— This species is an exception in the genus in having the supracaudal and infracaudal luminous 
glands present in both sexes. Widely distributed in the western tropical Pacific and in the Indian Ocean.
