to X. nudipes, and the latter species is, according to Alcock, described and 

 figured as having sharp fingers. 



Considering the difficulty of determining species in this group, and the 

 fact that I have no large series of specimens for comparison, the reference 

 of my specimens from the Kermadecs to A^. nudipes must be looked upon 

 as provisional only. 



Xanthodes lamarckii (Milne-Edwards). 



Xantho lamarckii Milne-Edwards, Hist. Nat., Crust., 1, p. 391, 1834. 

 Xanthodes lamarckii Whitelegge, Mem. Aust. Mus., 3, p. 130, 1897 ; 

 Alcock, Proc. Asiatic Soc. Bengal, 67, p. 157, 1898. 



Several specimens, male and female, from Coral Bay, Sunday Island, 

 collected by Mr. T. Iredale. 



These specimens agree closely with the description given by Alcock ; 

 the females have the abdomen fringed with long hairs, as described by 

 Whitelegge. 



The species is widely distributed in the Indo-Pacific region. 



Ozius lobatus Heller. 



Ozius lobatus Heller, Reise der " Novara," Crust., p. 21, pi. 2, fig. 4, 1868 ; 

 Haswell, Cat. Aust. Crust., p. 63, 1882. 



Three specimens, two males and one female. Mr. Oliver says this species 

 is fairly common among rocks between tide-marks. 



The specimens that I have been able to examine agree minutely with 

 Heller's description. The species is undoubtedly very closely allied to 

 0. truncatus Milne-Edwards ; but, as Heller points out, that species, accord- 

 ing to the description and figures by Milne -Edwards and Dana, appears 

 to have the front almost straight, while in 0. lobatus it is divided into 

 4 lobes ; the two inner ones are broad and rounded and the two outer 

 ones are narrower and rather more prominent, being similar to the small 

 rounded lobe at the inner angle of the orbit. 



0. lobatus and 0. truncatus are both recorded from Australia, and 0. 

 truncatus has also been found in New Zealand. The occurrence of 0. lobatus 

 at the Kermadecs renders it still more probable that the two species are 

 identical, but a comparison of typical specimens is desirable before the 

 two are combined.

One female specimen (both chelipeds missing) from Meyer Island, found 

 on coral, 1 fathom. The honeycomb network of fine brown lines on the 

 carapace is still very plainly marked in the spirit specimen. 



The species is wadely distributed in Indo-Pacific seas.
