In the " Catalogue of the Stalk- and Sessile-eyed Crustacea of 

 New Zealand," published in 1876, Miers gives a list, with 

 descriptions, of thirteen species of Anomura, belonging to nine 

 genera. Of these, Bemipes marmoratus and Fagurus im- 

 bricatiis do not belong to New Zealand at all, having been 

 collected by Hombron and Jacquinot at PbafHes Bay, which is 

 in Northern x\ustralia. Fagicrus pilosus, also of M. -Edwards, 

 belongs to Dana's genus Paguristes. In regard to the remain- 

 ing species, two of them — Eitpagums cristatiis, Edw., and 

 E. spinidimanus , Miers — have not again been identified, but I 

 retain them here provisionally. 



The number of species included in the present list is thirty- 

 five, belonging to sixteen genera. 



The Crustacea of this group are not well represented in the 

 seas of New Zealand — at any rate, in the littoral zone, which 

 is the only one which has been investigated up to the present 

 time. In individuals, such species as Petrolisthes elongatus
