Luciobrotula bartschi Smith and Radcliflfe in Radcliffe, 1913? 
Material.— CAS 236665 (95.0 mni SL, DC-1306); HEPD-006, otter trawl in 454-457 m.

Neobythites unimaculatus Smith and Radcliffe in Radcliffe, 1913 (Fig. 68) 
Material.— CAS 235745 (137.56 mm SL, DC-1456); HEPD-021, beam trawl in 132-172 m. CAS 235787

Remarks.— We have been advised by Hsuan-Chieh Ho (National Museum of Marine Biology & Aquai ium, 
Pingtung, Taiwan) diat tliis specimen should be tentatively identified as Chaunax sp., not Chaunacops cf 
colomtus. He added diat “when they are small, they tend to be dark and similar to Chaunacops.'''' The 
species was last treated by Caruso (1989) who found that "‘colomtus is currently known from the eastern 
Indian Ocean . . . and the type locality on the Cocos Ridge in the eastern Pacific Ocean .... In the Indi-
