THE CORAL TRIANGLE: HEARST BIODIVERSITY EXPEDITION 
an Ocean it has been taken between 16°S and 32°S and 87°E and 97°E at depths ranging from 1,250-1,733 
m.” He cautioned, however, that the lack of adequate eastern Pacific material (only the holotype, “wliich 
has suffered from mthless dissection”) precludes the recognition of those populations as conspecific. 
Chaunax sp. 2 (Fig. 73) 
Material.— CAS 236015 (52 mm SL); HEPD-021, beam trawl in 132-172 m. CAS 236014 (69 mm SL, 
DC-1493); HEPD-022, otter trawl in 115-144 m. 
Remarks. — We were unable to identify these small specimens, which may not be the same species. 
Ogcocephalidae (Batfishes) 
Remarks. — The Batfishes have not been tlioroughly reviewed and many taxonomic problems remain to be 
resolved, including the description of new species; as a consequence several of the HEPD specimens ar e 
left unidentified except to genus. Hsuan-Ching (“Hans”) Ho of the National Museum of Marine Biology 
and Aquarium, Taiwan, is currently working on the group. 
Dibranchus sp. (Fig. 74) 
Material.— CAS 234021 (75mm SL, DC-1385); HEPD-012, beam trawl in 721-761 m. CAS 234026 (53 
nun SL, DC-1407); HEPD-015, beam trawl in 757-836 m. 
Remarks.— We were unable to identify these specimens. 
Halicmetus sp. (Fig. 75) 
Material.— CAS 234019 (58 mm SL, DC-1386), HEPD-012, beam trawl in 721-761 m. CAS 236016 (55 
mm SL, DC-1572); HEPD-039, beam trawl in 633-642 m. 
Remarks.— We could not identify this to species. 
Halieutaea cf. stellata (Vahl, 1797) (Fig. 76a-b) 
Material.— CAS 236405 (120 mm SL, DC-1525); HEPD-030, beam tmwl in 190-201 m. 
Remarks. — Mochizuki {in Masuda et al. 1984:105) gives counts of P 13 and C 9, and also states that the 
ventral surface of the disc is white. Aside from these discrepancies, the HEPD specimen agrees with his 
description and color figure (pi. 91-H). Gloerfelt-Taip and Kailola (1984:97, color figure onp. 96) record¬ 
ed an unidentified Halieutaea that also agrees well with the HEPD specimen, especially in its disc shape 
(much wider than long), but they describe the ventral surface of the disc as covered witli fine spinules or 
simple spines, in contrast to the minute dennal denticles of the HEPD specimen. Disftibuted from Japan 
to the East Indies and west to India. 
Halieutaea sp. 
Material.— CAS 235678 (25.7mm SL) and CAS 236017 (2 spec.); HEPD-022, otter trawl in 115-144m. 
Remarks.— Bradbury {in Carpenter and Niem 1999:2025) lists five species but does not provide a key to the 
species. She notes, '"Halieutaea needs revision and most species distributions are little Imown. There are 
probably 5 or 6 species to be expected in tlie area.” 
Halkutopsis sp. 1 (Fig. 77) 
Material.— CAS 235685 (48 mm SL, DC-1422); HEPD-016, otter trawl in 892-966 m. 
Remarks. — This specimen is similar to Halieutopsis vermicularis Smith and Radcliffe, 1912, however, its 
coloration is much too dark. 
Halieutopsis sp. 2 (Fig. 78) 
Material.— CAS 235684 (2, 51-54 mm SL, DC-1420 and DC-1421); HEPD-016, otter trawl in 892-966 
m. 
Remarks.— The smaller specimen has black pectorals, the larger has pale pectoral fins.
