CRUSTACEA 301 
The specimen is a large male with carapace 55mm. long, and 
therefore considerably larger than the form described by Alcock, 
the carapace of which was only 40mm. in length, and very much 
larger than the specimen in the Canterbury Muuseum. The 
branchial region of the carapace is quite soft and membranous 
and the rostrum is much less prominent, the front being merely 
produced a little in the middle so as to be slightly convex. 
The ophthalmic scales have two well marked spines at the tip 
and the left one has two other spines well marked and one smaller 
one on the outer margin, while the right one has only two on 
the outer margin, both less distinct than the two terminal ones. 
The second pair of legs is only slightly longer than the 
chelipeds and the third pair is somewhat longer than the second; 
in both the dactyl is considerably longer than the propod. 
The specimen in the Canterbury Museum from ‘‘Polynesia’’ 
undoubtedly belongs to this species as described by Alcock, and 
differs from the Nora Niven specimen in having the rostrum 
much better marked and acute, the eye stalks rather more 
slender, the dactyls of the legs shorter and the curved lines of 
setae extending more continuously across the joints of the legs, 
while in the Nora Niven specimen they are more broken, the 
specimen also is somewhat more hairy on the chelipeds and legs 
and the anterior part of the carapace. It is however only about 
one-third the size of the Nora Niven specimen, and _ the 
differences are perhaps due to age.
