IWAMOTO & MCCOSKER: DEEP-WATER FISHES OF THE PHILIPPINE EXPEDITION295 
eral line does not mn close to the dorsal-fm base; Genyagnus monopteiygius (the only recorded species of 
the genus in the area) has a small chin barbel; and Ichthyscopiis lacks dermal appendages on the oral valve, 
has a relatively compressed head and body, has dermal folds on the belly, its basipterygium is not 
visible,and its upper cleithral spine has fringed demial flaps. There arc other uranoscopids lacking a spin¬ 
ous D fin that ai'e known fi'om outside the general area. Based onPietsch’s (1989) comprehensive study of 
phylogenetic relationships of the family, the HEPD specimen agrees most closely with his diagnosis of 
Kathetostoma, a genus containing seven species from western North Atlantic (2 spp.), tropical eastern 
Pacific (1 sp.). New Zealand (1 sp.), and southern Australia and Tasmania (3 spp.). If the specimen proves 
to be a Kathetostoma, it would be the first record of the genus in tropical waters of the western Pacific. It 
is beyond tlie scope of this report to attempt a species identification based on a single juvenile. 
Uranoscopus sp. 2 (of Kishimoto, 2001) (Fig. 137a-b) 
Material.— CAS 236423 (98 mm SL, DC-1450); HEPD-016, otter trawl in 892-966 m. CAS 236421 (72 
mm SL); HEPD-022, otter trawl in 115-144 m. 
Remarks. — These specimens key out to ‘"'Uranoscopus sp. 2” in Kishimoto’s key in the FAO Species Iden¬ 
tification Guide (Carpenter and Niem, 2001, vol. 6), and they agree rather well with the figure of that 
species on p. 3529 of that work, especially in the pigmentation pattern of the tins, which, however, are 
somewhat paler in our specimens. They do not agree with any of the described species from Japan (Kishi¬ 
moto, 1987; Nakabo 2000). Uranoscopus sp. 2 is known from the Philippines and Indonesia and attains a 
maximum size of 26 cm TL. 
Uranoscopus sp. 3 (of Kishimoto, 2001) (Fig. 138a-b) 
Material.— CAS 236477 (2, 40-48 mm SL); HEPD-022, otter trawl in 115-144 m. CAS 236487 (2, 
39.8-47.5 SL); HEPD-026, beam trawl in 82-86 m. CAS 236476 (58.1 SL, DC-1564); HEPD-036, beam 
trawl in 216-262 m. 
Remarks. — These specimens key out, more or less, to Uranoscopus sp. 3 in Kishimoto’s key {in Carpenter 
and Niem, 2001, pp. 3520-3523), although there are discrepancies, especially in terms of color (no bands 
or minute black spots) and fonn of appendage on its oral valve. Also, the disfribution of the species sup¬ 
posedly lies well to the east and south in Micronesia and the Coral and Arafura seas. It is possible that the 
differences may be attributable to the HEPD specimens being Juveniles. The specimens also keyed out 
closely to U. chinensis Guichenot, 1882 using Nakabo (2000). Other species of Uranoscopus recorded 
from the Philippines include U. bicinctus Temminck and Sclilegel, 1843, U. cognatus Cantor, 1849, 
U. japonicus Houttuyn, 1782, U. kaianus Gunther, 1880, U. tosa Jordan and Hubbs, 1925, and U. sp. 2 (of 
Kishimoto, 2001). 
Gobiidae (Gobies) 
Hazeus sp. (Fig. 139a-b) 
Material.— CAS 236631 (3, 32.2-35.5 mm SL); HEPD-026, beam trawl in 82-86 m over a hard-rocky bot¬ 
tom. 
Remarks. — These specimens appear to be witliin the genus Hazeus. They are very similar to Obliquogob- 
ius, however, the anterior spines of the fii'st and second dorsal fin ai'e thicker than the remaining fm spines 
and the nape and opercles appear to be partly scaled. All three specimens have a distinct V-shaped black 
mark above their caudal peduncle, vertical spots fonning four faint bars along the caudal fin, a black spot 
at the base of the pectoral fm, a dark black spot between dorsal spines V and VI (much like in O. mega- 
lops and O. sp. 3 in Shibukawa and Aonuma’s [2007] Fig. 3), and numerous black spots symmetrically 
occuii'ing on the snout and lower lip. We are advised by K. Shibukawa, H. Larson, and D. Hoese that they 
probably fall within Hazeus, a genus that is currently being revised. 
Obliquogobius Koumans, 1941 
Remarks. — The deepwater goby genus Obliquogobius was until recently known only from one central Indi¬ 
an Ocean and one Red Sea species. Shibukawa and Aonuma (2007) revised the genus, added three addi¬ 
tional species from Japan and included in their key, but did not describe, three additional species (from the 
Gulf of Aden, Fiji, and New Caledonia). Tliey also mentioned specimens of their new species O. cirrifer 
and O. yamadai collected from the Philippines, but did not include them as type specimens because of
