(Plates xxiv and xxv.) 



Amongst a collection of Asiatic Terrestrial Isopoda placed in 

 my hands by Dr. Annandale for identification, there are two 

 tubes, containing twenty-one specimens, collected in the Andaman 

 Islands and S. India. They include three species, viz., a new 

 species of Philoscia, Latr., of which there are only two imperfect 

 examples, a new species of Paraperiscyphis, Stebbing, and a new 

 species of Cubaris, Brandt. 



Gen. Philoscia, Latr. 



Philoscia, sp. 



The two examples from roots of ferns from Port Blair, 

 28-viii-o8, No. 8571/10 {H. Weskin) are too imperfect to des- 

 cribe. I have received the same species from various parts of 

 India and Burma.

Body (fig. i) oblong oval, dorsal face strongly convex, with 

 numerous rounded tubercles. Cephalon small, flanked laterally by 

 the lateral plates of the ist segment of the mesosome. Ventrally 

 carinate. Eyes sub-dorsal and well-developed. Antennulae small, 

 3-iointed, situated between the ventral carination of the cephalon 

 and the base of antennae. Antennae (figs, i, 2) moderately 

 stout with 2-jointed flagellum, the first joint longer than the 

 second. Mandibles (fig. 3). the outer cutting edge has three stout 

 teeth and a blunt process on the inner side, ist maxillae (figs. 4 

 and 5) have the outer lobe oblong and somewhat triangular in 

 shape, distally terminating in seven incurved spines, on the outer 

 margin there are a number of long, simple, hair-like setae. Inner
