of the ox - a] parts in other respects resembling that in the 4 preceding species. 
Second pair of legs with the terminal joint considerably produced, exceeding in 
length the 2 preceding joints combined. Uropoda rather slender, stem elongated 
and perfectly smooth, inner ramus about half the length of the stem, and armed 
with 8 spinules. Colour pale reddish. Length 5 V 2 mm. 
Adult male comparatively more slender than the female, with the carapace 
shallower. Uropoda still more elongated, and having the stem, as usual, clothed 
inside with slender setae, inner ramus more produced and armed with about 15 
spinules. Length 6 mm. 
Remarks.— In the nearly smooth and evenly vaulted carapace this form 
somewhat resembles the 2 species described at the head of this account. It is 
however in reality more nearly allied to some of the other species, for instance 
C. verrucosa, as regards the structural details. From any of the species it may 
be easily distinguished by the less tumid carapace and by the structure of 
the uropoda. 
Occurrence .—Only 2 or 3 specimens of this form have hitherto come 
under my notice. They were taken many years ago off the Lofoten Islands in 
a depth of 200—250 fathoms. This species has not been recorded more recently 
by any author.
