Colour blackish. Size probably more than 30 cm. Off
Cape Town, probably continuous with populations in Gulf
of Guinea and northern Atlantic; 900 - 1 500 m.

ahout 3.2--1.0 in head. ahout eyual to interorhital space. Teeth minute. in
hroad hands in upper jaw. in narrow hands on lower. G R ahout 1.5 in eye.
Overall flesh-coloured; blackish over operculum, gills,
suborbital; fins dusky. Attains 40 cm. Table Bay and Natal
coast, 940 - 2 560 m. Also in western North Atlantic and
eastern Atlantic south of Irish coast. Specimens reported by
Gilchrist & von Bonde (1924) - and on which Barnard
(1925) and Smith (1949) based their southern African
records of the species - are not in the J.L.B. Smith Institute or the South African Museum. The southern African
records are therefore not verified.
93.2 Bathygadus melanobranchus: head of 38+ cm SL (after Marshall &
Cohen, 1973) and whole fish, ca. 35 cm (compiled).

Overall colour blackish (with integument intact); body
apparently paler in juveniles. Probably attains more than 30
cm. Mozambique and Agulhas Bank, 1 280 - 1600 m (CAS

Genus Coelorinchus Giorna, 1809
More than 70 species, at least 7 in our area. The genus is
in need of revision.
