Paraperiscyphis scabrus, n. sp. 
(Pl. ix, figs. 6—r0). 
Body oblong oval, dorsal face strongly convex, richly tuber- 
culated. Cephalon (fig. 6) small, flanked by the Ist segment 
of the mesosome, lateral lobes well developed, median lobe small 
and confluent with carina of epistoma. Eyes subdorsal. Anten- 
nulae (fig. 7) small, 3-jointed, distal joint terminating as a cone. 
Antennae (fig. 8) with joints 2 and 3 subequal, 4th joint nearly 
twice as long and 5th nearly three times as long; flagellum 
2-jointed, with the first joint shorter than the second which has 
a fine terminal style. Whole of appendage sparsely covered 
with short bluntly ending setae. Uropoda (fig. 9) extending be- 
yond the telson, basal plate short and stout, with antero-dorsal 
surface expanded, convex dorsally with thickened antero dorsal 
margin bounding the antero-dorsal surface, concave ventrally with 
groove; exopodite and endopodite both extending beyond the 
basal plate and articulating on the inner margin. Telson (fig 10) 
obtusely triangular, dorsal surface convex, tuberculated. Length 
11I'5 X 6 mm. Colour (in alcohol) greenish-brown with yellowish 
mottling. 
Habitat —Peradeniya, Ceylon. No. *i5* (Ff. H. Gravely). 
Type.—In the collection of the Indian Museum. 
In the form of the telson and uropoda this species shows a 
relationship to P. pulcher, but is separated by the striking differ- 
ence in the shape and development of the lateral and median lobes 
of the cephalon, there are also well-marked differences in the form 
of the antennulae and antennae. 
Genus Cubaris, Brandt. 
The widely conflicting opinions held as to the position of this 
genus afford a typical instance of the very unsatisfactory state of 
the classification of the Terrestrial Isopoda. 
Brandt’s description', though brief, is quite clear, and the 
slight modifications suggested by Miers? in 1877 scarcely affect it. 
Budde-Lund? in his ‘ Revision’ p. 36, under the Family Oniscidae, 
subfamily 7 Oniscinae, Tribe rt Armadilloidea, cites the genus 
Armadillo, Dum., and under Tribe 2 Oniscoidea, the genus Armadil- 
dium, Brandt, and from the later text we gather that the genus 
Cubaris is sunk as a synonym of Armadillo. In tgto* (p.g) the 
genus is recognized and appears between Armadijlo, Dum., and 
Pertcephalus, B.-l,., whilst in 1912° it is regarded by him as a 
subgenus only, in the subfamily Oniscinae.
