146 Records of the Indian Museum. [ Vou. Ben: 
maxillae (fig. 5), outer palp terminating in four stout curved spines 
and four smaller ones with bifid terminations, inner lobe with short 
blunt spine on the outer side and two setaceous spines on the 
inner side. Second maxillae (fig. 6) thin, plate-like, bilobed, inner 
lobe setaceous. The segments of the mesosome somewhat de- 
pressed, lateral plates small, slightly deflected outwards, the 
posterior angle of 5-7 produced backwardly, as also those of the 
three last metasomatic segments. Maxillipedes (fig. 7), outer palp 
with multispinous process on the outer side and three long spines 
internal to this, the inner palp has two spines and four small 
tooth-like processes on the margins. Thoracic appendages (fig. 8) 
fringed with stout spines on the inner side of the three distal 
joints. Uropoda (fig. 9) extending beyond the telson, basal plate 
with lateral extensions dorsally and ventrally, with the former 
the slightly curved endopodite articulates, the exopodite which is 
cuniform articulates at the base of the basal plate. Exopodite 
nearly twice the length of the basal plate, and of the endopodite, 
both covered with fine setae. Telson (fig. 10) short, not extend- 
ing beyond the basal plates of the uropoda, triangular, apex sub- 
acute. Length 75 mm. Colour (in alcohol) greyish- brown, cepha- 
lon and metasome usually darker, lateral plates of mesosome 
with dark patch uniformly a blackish-brown, very variable. 
Habitat.—Under stones and dead water weeds at edge of 
Chilka Lake, Rambha, Ganjam, Madras Pres., 27-xii-13, No. 
8692/10. ‘‘ Apparently an amphibious species’’. (N. Annandale.) 
Type.—In the collection of the Indian Museum. 
This species is closely allied to Porcellio tmmsz, Clige.,! which 
latter must now be referred to the genus Hemiporcellio ; it differs, 
bowever, from zmmsz in the form of the antennae, in the anterior 
margin of the cephalon, which is continuous, and in the form of 
the uropoda. 
The colour is exceedingly variable. Examples measuring 5°5 
and 6 mm. invariably have the first three and last mesosomatic 
segments a reddish-brown colour and the whole of the metasome 
a deep blackish-brown. Similar variations obtain in H. immsi 
judging from an immature specimen. 
Hemiporcellio hispidus, n. sp. 
(Plate vii, figs. 1-9.) 
Body oblong-oval, flattened, tuberculated and covered with 
fine setae; metasome narrower than the mesosome. Cephalon 
(figs. 1 and 2) small, tuberculated, lateral lobes slightly cup-shaped, 
median lobe absent, anterior margin distinct and continuous, 
epistoma convex and covered with stellate setae. Eyes small, 
sub-dorsal. Antennulae small, 3-jointed, basal joint prominent. 
Antennae (fig. 3) elongated, with well-marked carination on the
