TERRESTRIAL ISOPODA OF NEW ZEALAND. 143 



segment is a group of more or less distinct flexuous stripes. Leng'th attaining 

 14 mm." (Sars.) 



Habitat.— '^chon f J. C. Gully), and Mount Egmont (S. H. Drew). 



Remarks. — I have a few specimens from Nelson and one from Mount Egmont tliat 

 undoubtedly belong to this species, whicli is very -widely distributed througliout all 

 Europe, and the adjiieent parts of Asia and Africa. According to Budde-Luud it has 

 also been widely dispersed, probably by artificial means, and has lieen found at New 

 York, Monte Video, Melbourne, &c. It has not been previously recorded from New 

 Zealand, and it is a little strange that it should have been taken at Nelson and Mount 

 Egmont, when it has not yet been found at any of the chief ports or in other parts 

 of the Islands. 



My specimens agree very closely witli the figures and descriptions given l)y Sars and 

 Dolll'us, and I have been able to comjjare them with specimens from England, and 

 can find no points of diflPerence between them. In the male the first pair of legs has 

 the carpus a little more swollen than is shewn in Sars' figure, and has the propodos 

 bent back ujion it so as to form ait imperfectly subchelate hand. I find, however, that 

 the degree to which this structure is developed varies in different individuals, and it is 

 perhaps fully developed only in the adult male, or perhaps only during the breeding 

 season. The long ischium of the seventh pair of legs is also a characteristic of the fully- 

 grown male ; in the females it is only of normal length ; in the male, too, the meros 

 and carpus of the first six pairs of legs, and especially of the foui-th, fifth and sixth, 

 are much more setose than in the female. 



With regard to tlie coloui*, Budde-Lund distinguishes two varieties : first, immaculata, 

 " e plumbeo griseus," and second, cariegata, " annidorum marginibus albis serieque 

 dorsali triplici vel quadruplici macularum flavarum." Dollfus, who has given a detailed 

 account of this species in the work quoted, says : " Les 6 sont generalement d'un gris 

 uniforme, ou avec quelques taches safranees; les 2 d'un brun plus ou moins clair, avec 

 des taches et marbrures pales." The few specimens that I have from New Zealand 

 are all males, and are of a uniform dark slaty-grey colour. 



Genus 2. Armadillo. 

 Armadillo, Eufkle-Liind, Isopoda Terrestria, p. 35 (1885). 



(icneric Characters. — Ptesembling Armadillidiimi in most respects, but with the shield 

 on the epistome much less marked, and the grooves for the antennae consequently very 

 shallow ; the side-plates of the first segment of the mesosome usually, and those of 

 the second segment sometimes, incised or grooved ; the last segment of metasome 

 subtetragonal, broader at the base than apex, sides concave ; the outer branches of all 

 the pleopoda \i itb air-cavities: uropoda with the base large, flattened and produced so 

 as to fill up the space between the side-plates of the fifth segment and the terminal 

 segment; outer branch small, inserted on inner margin of the enlarged base ; inner 

 branch arising more anteriorly, quite concealed in dorsal view by the terminal segment. 



This genus contains many species, a large proportion of which ai-e found, as Budde-
