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

 fectly smooth and shining. Cephalon small, flanked laterally by 

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

 absent. Antennulae (?). Antennae (fig. 2) slender and elongated 

 with 3-jointed flagellum. Mandibles (fig. 3) small, beneath the 

 teeth is a single palp terminating in setose bristles, ist maxillae 

 (fig. 4): outer lobe terminates in eight spines, the four innermost 

 of which are bifurcated; the inner lobe terminates in a number of 

 fine spines. 2nd maxillae (fig. 5) thin and flexible, on the outer 

 side it is produced into a tooth-like plate and a smaller tooth on 

 the inner side, between which is a palp terminating in setose 

 bristles. The segments of the mesosome are strongly convex, 

 the lateral plates of i — 4 overlap one another slightly, whilst 

 those of 5 — 7 are produced backwardly, especially the 7th. Maxil- 

 lipedes (fig. 6) poorly developed. Thoracic appendages (fig. 7) 

 elongated, with simple and plumose spines on the protopodite. 

 Metasome narrow, lateral plates small and slightly incurved. Uro- 

 poda (fig. 8): basal plate flattened, extending beyond the telson, 

 exopodite long and pointed, endopodite similar in shape, but 

 smaller. Telson triangular, with peculiar lateral bosses. Colour

 No, 8079/10. (F. H. Gravely). 



Type. — In the collection of the Indian Museum 



Unlike any other cave- inhabiting species I know of, this 

 species has a very distinct colour. Packard' in his account of the 

 cave fauna of North America states, '' As regards change of 

 colour, we do not call an exception to the general law, that all 

 cave- animals are either colourless or nearly white, or, as in the 

 case of Arachnida and insects, much paler than their out-of-door 

 relatives."
