BARBADOS-ANTIGUA REPORTS 79 
This species differs from C. heterochelis, with which it also might be 
confused, in having a sharply carinated and longer rostral crest; the 
rostral crest too, is higher, rising just behind the orbital hoods and a 
little above their level, the hoods themselves are more abruptly domed, 
making the orbito-rostral depressions appear deeper and more sharply 
defined than in C. heterochelis. Furthermore, in the latter the blade of 
the antennal scale is about or nearly as long as the spine, distally trun- 
cate, bluntly rounded off, and three or four times wider than the ad- 
jacent portion of the spine; both blade and spine exceed the antennular 
peduncle; in C. nuttingi the spine exceeds the antennular peduncle a little 
and exceeds the blade considerably, the latter reaching about to the 
middle of the last segment of the antennular peduncle, distally it is 
sharply rounded off and narrow, scarcely wider than the adjacent portion 
of the spine. Paralleling the lower margin, on the inner face of the 
larger hand of C. heterochelis there is a distinct sulcus running from the 
notch to the articulation of the carpus, of which there is no trace in 
C. nuttingi, the inner face of the hand being merely a little flattened 
above the lower margin; moreover, the inner face of the fingers, and 
anterior portion of the palm are very hairy, while in C. heterochelis the 
hairs are few, and mostly marginal, so that the inner face of the hand 
is practically naked; in these particulars the larger hand of our species 
is like that of C. armillatus.
