or quite obsolete, the short prominence, however, being noticeable. The 

 upper lUiirgin of the larger (right) cheliped is more even than is shown in 

 Wliitelegge's figure. The chelipeds are unequal in both sexes. 



This hermit-crab is somewhat pecuUar in its habits ; it was found by 

 Mr. Oliver under stones between tide-marks, and he states that it was not 

 common, and that it never iises a spiral shell, but manages to keep on its 

 back a single valve of a bivalve mollusc's shell or a vacant Siphonaria or 

 limpet shell. 



Only three species of this peculiar genus are as yet known- — viz., P. 

 edivardsi, from Campbell Island and the Snares ; the present species ; and 

 P. platei, from Juan Fernandez. The description of this latter species I 

 have not yet been able to obtain. Mr. Whitelegge's specimens were dredged 

 in .54-59 fathoms, off the coast of New South Wales, and the species to 

 which they belong is much smaller than P. edwardsi, and appears to differ 

 also in having the chelipeds unequal in the female, while in the female of 

 P. edivardsi, according to Filhol, the chelipeds are small and subequal. 



Eupagurus sinuatus Stimpson. 



Eupagurus sinuatus Stimpson, Proc. Acad. Nat. Sci. Philad., 10, p. .348, 

 ' 1864 ; Haswell, Cat. Aust. Mus., p. 153, 1882 ; Alcock, Cat. Indian 

 Decap. Crust., pt. 2, Anomura, p. 175, 1905. 



Three specimens from Meyer Island seem to belong to this species. 

 They agree fairly well with the short description quoted by Haswell, espe- 

 cially in having the merus of the chelipeds deeply excavated below, the 

 margins provided with long cilia, and external margins spinose ; the carpus, 

 however, does not show much trace of a smooth median line, and the median 

 series of spines on the propod is not well marked. 



The species has been recorded from Port Jackson, Australia. 



Eupagurus hectori Filhol.* 



Etipaqurus hectori Filhol, Mission de I'ile Campbell, p. 419, pi. 51, fig. 1, 

 ' 1885 ; Thomson, Trans. N.Z. Inst., 31, p. 177, 1899 ; Lenz, Zool. 

 Jahr., 14, p. 447, 1901 ; Alcock, Cat. Indian Decap. Crust., pt. 2, 

 Anomura, p. 176, 1905. 



Numerous specimens from Meyer Island, and from Coral Bay, Sunda}' 

 Island, living in shells of various gastropods. These agree closely with 

 Filhol's description, and can be readily distinguished from other New Zea- 

 land species by the glabrous chelipeds. The chelipeds and the greater 

 part of the ambulatory legs in spirit specimens are coloured red. 



Filhol states that this species becomes more abundant to the south of 

 New Zealand, especially in Stewart Island ; Thomson records it from 

 Stcwarf Island, and Lenz from D'Urville Island, and I have recently 

 received a specimen from Miss Shand from Chatham Islands. 



* 1 have also from Meyer Island several specimens of a small hermit-crab which in 

 general resembles Eupagurus, but haf, the abdomen straight, though soft, and the telson 

 anil uropoda symmetrical. A fuller description is held over in the meantime, as I am 

 not siu'e of the systematic position of the species.
