Terrestrial Isopod from New Zealand. 329 



Length of largest specimen about 7 mm. 

 Loc. Under the bark of fallen logs in the bush, Levin, 

 Wellington, N.Z. 



Tills species appears to be closely related to Cuharis suteri, 

 Cliiltoii, the structure of the lateral margin of the first and 

 SHCond segments of the perteoii and of the uropoda being 

 closely similar in the two species. In C. snleri, however, 

 the ridges are transverse and mainly confined to tiie posterior 

 border of the peraion segments, while in the present species 

 the ridges are longitudinal, extending along nearly the whole 

 of the length of each segment, and they are much better 

 developed and consequently more prominent. Another 

 tuberculate species, C. hnmiltoni (Ohilton) *, probably also 

 comes near to these two species ; but the dorsal surface is much 

 more profusely supplied with flanges or ridges and with 

 })ointed tubercles. C. hamiltoni is known only from the 

 single type-specimen which was obtained in the neighbourhood 

 of Petane, near Napier, in New Zealand, and this specimen is 

 unfortunately somewhat imperfect, so that our knowledge of 

 the species is far from complete. The only other tuberculate 

 species known from New Zealand is C. macniahoni (Chilton)j 

 originally described from Kenepuru in Marlborough, though 

 I have since had specimens sent to me from one or two 

 localities in the North Island. C. spinosus (Dana) is a spiny 

 species, " the body bristled throughout with subacute S|)ines " ; 

 but it is only known from Dana's biief description and tigures, 

 no specimen having been since collected. It was found by 

 Dana near the Bay of Islands. 



I am much indebted to my assistant, Miss E. M. Ilerriott,^ 

 M.A., for preparing the drawings to illustrate this paper.
