116 Records of the Indian Museum. [ Vor. elie 
This is an additional record for this interesting species. 
I find that in describing this species I made a most unfor- 
tunate slip in the diagnosis wherein it was stated (p. 207) ‘‘2- 
jointed flagellum, the first joint longer than the second,” and 
again on p. 208 the error was repeated. In P. stebbingi the first 
joint of the flagellum zs not longer than the second, but as correctly 
figured (cf. pl. xxiv, figs. 1 and 2). 
Paraperiscyphis gigas (Cllge.). 
1g15. Periscyphis gigas, Collinge, Rec. Ind. Mus., vol. XI, p. 148, pl. ix, 
figs. I-10. 
The form of the uropoda, which is a character of the very 
greatest importance in the classification of this and allied genera, 
will necessitate the removal of this species to the genus Paraperi- 
scyphis. 
Paraperiscyphis pulcher, n. sp. 
(Pl. ix, figs. I—5). 
Body oblong oval, dorsal face strongly convex, surface irregu- 
lar but smooth. Cephalon (fig. 1) small, flanked by the lateral 
plates of the first segment of the mesosome, lateral lobes well 
developed, median lobe represented by slight median expan- 
sion of the anterior margin; epistoma carinate. Eyes subdorsal. 
Antennulae (fig. 2) small, 3-jointed, distal joint with terminal 
style and indented on the inner side. Antennae (fig. 3) moderately 
stout, joints 2-4 subequal, 5th joint the longest; flagellum 2-jointed, 
with the first joint shorter than the second which has a fine 
terminal style. Uropoda (fig. 4) extending beyond the telson, 
basal plate short and stout with antero-dorsal surface expanded, 
convex dorsally, concave ventrally; exopodite and endopodite 
extending beyond the basal plate, both articulating on the inner 
margin, exopodite flat and blade-like, endopodite three-sided. 
Telson (fig. 5) obtusely triangular, dorsal surface convex, irregular 
andsmooth. Length14°5mm.X7mm. Colour (in alcohol) greyish- 
green ground colour with small irregular blackish spots on the 
posterior border of each mesosomatic segment, in the median line 
on each mesosomatic and metasomatic segment is a yellowish spot, 
lateral to this an irregular yellowish marking, and still more laterally 
another spot, which together give the appearance of five broken 
lines. 
Habitat.—Peradeniva, Ceylon, 28-v-1910. No. *10* (Ff. 4. 
Gravely). 
Type.—In the collection of the Indian Museum. 
The form of the cephalon, antennae and uropoda separate this 
handsome species from any other member of the genus. There being 
only a single example, I have not attempted any examination 
of the mouth-parts.
