Remarks.
Two specimens from Station 394B are very large (dd. 76 and dd.
81 mm
) and are typical of the species (
Fig. 22A–B
). A medium-sized specimen (dd.
30 mm
) is uniformly covered with fine pustules and occasional larger ones (
Fig. 22C–E
). The arms are bifurcated 16–17 times and carry girdle bands after the first branch. Otherwise the description matches that in
Baker, (1980
p. 66) of material from the eastern Indian Ocean.
Distribution.
Originally described from USFC
Albatross
material from the
Philippines
, this shallow water basket star is widely distributed in the Indo-Malaysian region, and in the east
China
Sea in
73–300m
depth (
Baker, 1980
), and its occurrence off Durban and further north off
Mozambique
, is not unexpected.
