The collection contains a single female specimen, taken at Station 96, off the north iV7d- ?./3V 
end of New Zealand, of a species of the very interesting genus PorceUanopagurus. It 
probably belongs to P. edwardsi , but its great chela differs considerably from that of 
the male specimen described and figured by Chilton. The scales on the wrist are 
coarser and less regular, the upper edge of the palm has a well-marked, though 
irregular, crest of sharp granules or teeth, and along the lower edge there runs a 
strong, regular line of fine granules, such as appears to lie present in P. japonicus, 
Balss, 1913. Very possibly these differences are sexual, and in any case the examina¬ 
tion of a series of examples would be necessary before a new species could be 
established for the form taken by the “ Terra Nova.” The specimen forms the subject 
of a separate report (p. Ill below).

The collection contains a female specimen of this very widespread species, dredged 
in moderately deep water off New Zealand. It is of small size (7 mm. long), but 
closely resembles a rather larger British specimen with which I have compared 
it, and also, as the accompanying figure shows, the representation given bv 
Bell. The only respect in which it differs from the British form is a greater 
indistinctness of the regions of the carapace. It does not agree with the variety 
subcorrugatus, A. M.-Edw., 1861, from the Red Sea in the features in which 
that variety is unlike the type. Specimens from Australia and Japan have the 
regions of the carapace strongly marked, but show no constant difference from the 
British form.
