IWAMOTO & MCCOSKER: DEEP-WATER FISHES OF THE PHILIPPINE EXPEDITION279 
the premaxillary as depicted in those works. They more closely resemble P. japonicus in that respect, but 
the scales are much smaller and the D lobe is intensely black in that species. 
Moridae (Morid Cods) 
Physiculus longifilis Weber, 1913 
Material.— CAS 235569 (55 mm SL); HEPD-022, otter trawl in 115-144 m. 
Remarks. — The elongated pelvic fin is apparently distinctive among members of the genus; this and the few 
D rays (about 60) and the absence of scales on D and gular membranes are diagnostic. So far known only 
from the Flores and Sulu seas and off southwestern Luzon (HEPD specimen). 
Physiculus rhodopinnis Okamiira, 1982 (Fig. 47) 
Material.— CAS 235782 (85.0 mm SL, DC-1433); HEPD-017, beam trawl in 282-128 m. 
Remarks, — This very small specimen agrees relatively well with the original description and Paulin’s (1989) 
revised description using more comparative material. The developed gill rakers appeared somewhat longer 
and more slender than shown in Okamura’s (fig. 78C) figure, and the gular membrane completely lacked 
scales (altliough Paulin states “...gular scales usually [italics added] present.” Furthermore, scales on the 
mandibular rami were of two sizes, several larger ones posteriorly placed, and most of the remaining sur¬ 
faces covered with tiny embedded scales that did not taper to one row anteriorly. Tlie size of the HEPD 
specimen may have a bearing on these character differences. This specimen is the first record of the species 
from Philippine waters. 
Bregmacerotidae (Codlets) 
Bregmaceros japonicus Tanaka, 1908 (Fig. 48) 
Material.— CAS 236708 (55 mm SL, DC-1293); HEPD-005, beam trawl in 459^96 m. CAS 236480 (3, 
81-106 mm SL); HEPD-006, otter trawl in 454-457 m. CAS 236483 (3, 49.8-70.5 mm SL); HEPD-016, 
otter trawl in 892-966 m. 
Remarks. — This species is one of several that were captured during tlie Expedition, but we could not iden¬ 
tify the others to species. 
Bathygadidae (Bathygadids) 
Bathygadiis entomelas Gibert and Hubbs, 1920 (Fig. 49) 
Material.— CAS 233710 (38.6 mm HL, 169+ mm TL, DC-1345); HEPD-Oll, otter trawl in 636-6664 m. 
CAS 233711 (40.2 mm HL, 178+ mm TL, DC-1380); HEPD-012, beam trawl in 721-761 m. 
Remarks. — The following combination of characters fairly well distinguish this species from its congeners: 
V 10, GR-I 6+19; gill rakers long, slender, with pointed tips; fins lacking prolonged rays; no chin barbel; 
interorbital wider than orbit, and pyloric caeca around 36. 
Bathygadiis spongiceps Gibert and Hubbs, 1920? (Fig. 50) 
Material.— CAS 236494 (ca. 27 mm HL, 131+ mm TL, DC-1415); HEPD-016, otter trawl in 892-966 m. 
Remarks.— This single damaged juvenile is tentatively identified as B. spongiceps based mainly on the 
counts of the pelvic fins (9), gill rakers (5+1+21), pyloric caeca (about 14), and dimensions of its orbit 
(20% HL), interorbital (33%), upper Jaw (57%), and suborbital (16%), The genus is in need of revision. 
Bathygadiis spongiceps (or a species veiy much like it) has been broadly recorded from the Philippines 
south to Indonesia, Australia, and in the southwestern Pacific (Coral Sea, off New Caledonia and adjacent 
regions). 
Gadomus denticulatus Gilbert and Hubbs, 1920 
Material.— CAS 233712 (33.0 mm HL, 185 mm TL); HEPD-006, otter trawl in 454-457 m. 
Remarks. — The species is closely similar to G. colletti from Japan (the range possibly extends to Western 
Austraha; see Iwamoto and Williams 1999:117) differing in G. colletti having somewhat more GR 
(4-6+21-23, total 25-28), more pyloric caeca (95), and longer barbel (3X orbit).
