IWAMOTO & MCCOSKER: DEEP-WATER FISHES OF THE PHILIPPINE EXPEDITION285 
Malthopsis annulifera Tanaka, 1908 (Fig. 79) 
Material.— CAS 235680 (46.5 mni SL, DC-1546); HEPD-032, beam trawl in 223-369 m. 
Remarks.— Widely distributed in the western Pacific, from Japan southward to the Philippines and south¬ 
eastward to New Caledonia, in 90-360 m. 
Malthopsis kohayashii Tanaka, 1916? (Fig. 80) 
Material.— CAS 235679 (76 mm SL, DC-1534); HEPD-032, beam trawl in 223-369 m. 
Remarks. — This specimen keys out to Malthopsis lutea Alcock, 1891 in most references, however. Ho and 
Shao (2010) show that m. lutea is limited to tlie Andaman Islands and tliat m. kobayashii is the widespread 
Indo-West Pacific species. It has four dorsal-fm rays. The fins are pale and the specimen lacks some of the 
pigmentation of m. kobayashii. H-C Ho {in litt. 2013) suggests that it might be either Malthopsis tiarella 
Jordan, 1902 orm. asperata Ho, Roberts and Shao, 2013. 
Hmantolophidae (Footballfishes) 
Himantolophus appelii (Clark, 1878) 
Material.— CAS 235600 (female, 74 mm SL); collection data lost. 
Remarks.— This specimen probably represents a new Philippines record, although the species is circum- 
global in the southern hemisphere (except the eastern Pacific). 
Ateleopidae (Jellynose) 
Ateleopus japonicus Bleeker, 1853 (Fig. 81) 
Material.— CAS 235514 (638 mm SL, DC-1331); HEPD-009, otter trawl in 322-336 m. CAS 235794 (291 
mm SL; DC-1526); HEPD-030, beam trawl in 190-201 m. CAS 235639 (1 spec.); HEPD-030, beam trawl 
in 190-201 m. 
Remarks. — Several species of Ateleopus occur in the region of the South Cliina Sea, East China Sea and 
Japan, including one that is apparently undescribed (Tatsuya Kaga, in litt. 19 June 2013). 
Trachichthyidae (Slimeheads) 
Hoplostethus melanoptenis Fowler, 1938 (Fig. 82) 
Material.— CAS 23998 (82 mm SL, DC-1299); HEPD-006, otter trawl in 454-457 m. CAS 234018 (4, 
99-162 nmi SL, DC-1346, -1348, -1349); HEPD-011, otter trawl in 636-664 m. 
Remarks. — We have compared our specimens to a paratype of H. melanopterus (CAS-SU 40191, 82 mm 
SL). They are conspecific, The 162 mm SL specimen (DC-1347) agrees in counts and proportions with the 
species, but differs in having pale rather than black pectoral fins. Martin Gomon {in litt. 11 Nov. 2013) sug¬ 
gests that fin coloration can change with growth in Hoplostethus, however, this species has not been ade¬ 
quately studied. Gomon advises us that Hoplostethus melanopterus should be in another genus. We provi¬ 
sionally include it in Hoplostethus for this listing. 
Hoplostethus sp. 
Material.— CAS 233985 (97 mm SL; DC-1277); HEPD-004, otter trawl in 154-245 m. 
Remarks. — This specimen appears identical to Hoplostethus ravurictus Gomon, 2008 from Australia in its 
coloration (body and buccal cavity) and in its counts. We have compared it to the pale CAS paratypes 
(CAS 227136, 3 paratypes 79-116 mm SL), and they seem to be the same. Martin Gomon (NMV, in litt., 
24 Oct. 2013) has advised that such a distribution is unhkely for Hoplostethus and that they are probably 
not conspecific. We will pursue a comparative analysis of the COL 
Hoplostethus sp. 
Material.— CAS 236495 (25.1 mm SL); HEPD-036, beam trawl in 216-262 m. 
Remarks.— We were unable to identify this small individual.
