The only example hitherto recorded is A. Milne-Edwards’s type-specimen 
from Upolu, one of the Samoan Islands. With his description and figures 
the present specimens agree except in (a) the proportion of length to breadth 
of the carapace, the measurements in Milne-Hdwards’s type-specimen, pro- 
bably a young ?, being C.l. 7 mm. and C.b. 14 mm. ; (0) the granulation of 
the branchial regions, which is probably more distinct in my specimens; 
(c) the shape of the abdomen, which in my ¢ differs from Milne-Edwards’s 
figure ; as, however, the latter represents very well the abdomen of my young 
2 of C.l. 7°25 mm., it appears that Milne-Hdwards’s figure is wrongly labelled 
in regard to sex, and that no real difference is involved under this head. 
In addition to the points given in Milne-Hdwards’s description, my speci- 
mens have (a) some hair distributed in various places, and (6) some granu- 
lation on the walking-legs. In detail, hair occurs (.) on lateral borders of 
the carapace; (ii.) on upper border of the merus of Ist, 2nd, and 3rd pairs 
of walking-legs ; (iii.) on both borders of the 4th pair of walking-legs, 
except that it is almost absent from the lower border of the carpus and distal 
half of the lower border of the merus ; on this 4th pair, moreover, the hair 
is more strongly developed than on the meri of the first three pairs ; 
(iv.) in all the females on the upper border of the cheliped and flanking the
