surface, sides of the segment directed obliquely backward, so 

 that the lower half of the posterior margin forms a distinct 

 angle with the upper half; following segments verj narrow 

 transverse, each with an impressed line running parallel to the 

 posterior margin ] the second, third, fourth, and fifth seg- 

 ments narrowed on the sides, which have their inferior margins 

 rounded ; the sixth and seventh segments broader on, the sides, 

 with the inferior margins truncate. Pleon very short, with 

 the segments (the last two excepted) nearly linear-transverse ; 

 terminal segment much the broadest at base, with the sides at 

 first suddenly converging and then parallel. Appendages of 

 the penultimate segment with the inner (terminal) joint reach- 

 ing to the end of the produced portion of the penultimate 

 joint.

Porcellio graniger^ n. sp. Type, B.M. 



Porcellio (franiyer, List Crust. Brit. Mus. p. 09 (1847), sine descr. 



Oblong-oval, moderately convex, granulate, the granules 

 seriate along the posterior margin of each segment, and partly 

 seriate elsewhere. Head transverse, with tlie antero-lateral 

 lobes narrow and very prominent. Eyes small, black. Seg- 

 ments of the pereion slightly tending backward at their latero- 

 posterior angles. Segments of the pleon very short, smooth 

 on the sides, and with the latero-posterior angles acute, directed 

 backward ; terminal segment triangular, acute, concave above, 

 narrowed posteriorly, scarcely reaching beyond the latero- 

 posterior angles of the penultimate segment. Appendages of 

 the penultimate segment very short, reaching a little beyond 

 the apex of the terminal segment ; the larger (exserted) ramus 

 ovate. Legs armed with slender acute spines. Colour light 

 chestnut-brown. 



Length § inch. 



Hah. New Zealand. 



Very nearly allied to P. gemmulatus^ Dana, from California, 

 but differs in the much shorter, broader, ovate pleonal appen- 

 dages, and in the spines of the legs not being laminated. 



Porcellio zealanclicus. Type, B.M. 



Porcellio zealandicm, List Crust. Brit, Mus. p. 90 (1847), sine descr. 



Elongate-oblong, finely granulous, the granules seriate on 

 the posterior margin of each segment. Head small, trans- 

 versely oblong, with the latero-anterior angles not prominent.
