I have no doubt froin the figure and descriptions above 

 quoted that P. cavipes and P. cultratus. White, are the 

 same species aS' P. dcfoi-mis, Milne-Edwards. The pro- 

 minent ridge on the third left leg gives it an excavated 

 appearance. I can find no characters by which to distin- 

 guish the single specimen of Pagurus cultratus. White, in 

 the British Museum, from the Philippines, from the 

 younger specimens of P. eavipics, from Australia. The 

 largest specimen of P. cavi2)cs (the one figured) has the 

 larger liand more distinctly tubercular and granulated, 

 and the tarsus of the third leg on the right side pro- 

 portionately longer, but these peculiarities seem due to the 

 age of the specimen. The figure badly represents the 

 excavated tarsus of the third leg on the left side.

Carapace oblong, the sides slightly curved, the lateral 

 margins with seven teeth. Front three-spined, the middle 

 spine projecting considerably beyond the eyes, the lateral 

 ones not quite half as long as the middle spine, and not 

 projecting beyond the eyes. A second smaller spine behind 

 each of the lateral frontal spines. A spine on either side 

 of the middle line in the gastric region. Second third and 

 fourth abdominal segments with a spine on either side of 

 the middle line. The arms are now wanting in both the 

 specimens in the Museum. 



Hab. Auckland Islands, Eendezvous Cove. Type. B.M. 



The specimens obtained in the U.S. Explor. Exped. at 

 Terra del Fuego, and referred by Dana with doubt to this 

 species (U.S. Explor. Exped. XIII., p. 479, pi. 30, f. 7) 

 differ in the number and arrangement of the spines on the 

 carapace, and the sliape of the hands, and are no doubt 

 specifically distinct.
