seems to differ very essentially in the marginal armature of the caudal lamine; these 
tufts, which with a magnifying power seem to be separate spines, consisting really of 
fascicles of minute sete; the terminal claw is well developed and bears at its base a 
single spine. Females only were found, length 0-66 mm. 
A few specimens found in a fresh-water gathering from Macquarie Island (H. 
Hamilton).

Taken in gatherings from off Maria Island, Tasmania, in depths of 100 fathoms 
(10th January, 1914) and (9th January, 1914), and in 50 fathoms (6th January, 1914) 
and (11th January, 1914). 
These specimens differ from the typical Greenland specimens of Prof. G. O. Sars, 
in having no distinct reticulated sculpture of the shell and in the absence of teeth on 
the postero-ventral margin. In these characters they are more like C. maxima Brady 
and Norman.
