105. Oniscus pubescens. 
Oniscus pubescens, Dana, U.S. Explor. Exped. xiv, Crust. part ii, 
p. 730, pl. xviii, fig. 2, (1853). 
Body pubescent, subelliptic. Abdomen abruptly much narrower 
than thorax, short, not longer than broad, last segment very short 
transverse, and not produced backward. Head transverse, a little 
shorter and narrower than next segment. Thoracic segments nearly 
equal in length, last on either side acute, but hardly prolonged. 
Caudal stylets quite small, shorter than abdomen, branches very 
unequal, very slender, acute. Antenne finely hirsute. Colour brown 
and brownish-white, with irregular bands and spots of deeper brown. 
Length 3 lines. (D.). 
New Zealand, ten miles up the Whykare River (Dana). Under 
rotten wood in forests. 
I have not seen specimens of this species. 
PORCELLIO. 
Porcellio, Latr. Hist. Nat. Crust. vii, p. 45, (1804); M. Edw. Hist. 
Nat. Crust. ii, p. 165, (1840) ; Dana, (sub-gen.) U.S. Explor. Exped. 
xiv, Crust. part u, p. 715, (1853). 
Characters generally of Oniscus, but with the external antenne 
seven-jointed, the flagellum containing only two joints, (besides the 
minute jointed terminal appendage). 
Scarcely distinct as a genus from Oniscus, of which this group is 
considered a sub-genus by Dana. Most authors however have 
regarded it as a genus.

Porcellio graniger, List Crust. Brit. Mus. p. 99, (1847), sine descr. ; 
Miers, Ann. Mag. Nat. Hist. (ser. 4) xvii, p. 226, (1876). 
Oblong-oval, moderately convex, granulate; the granules seriate 
along the posterior margin of each segment, and partly seriate else- 
where. Head transverse, with the antero-lateral lobes narrow, and 
very prominent. Eyes small, black. Segments of the thorax slightly 
tending backward at their latero-posterior angles. Segments of the 
abdomen very short, smooth on the sides, and with the latero-posterior 
angles acute, ‘directed backward, terminal segment triangular, acute,
