the XanthidsB: it may prove to belong to that family, where 1 have 

 already, with reserve, placed it. 



I may here, however, state that it closely resembles Filamnoplax, 

 having a flat, depressed, sliglitly transverse carapace. It differs from 

 Piluninojilax in the following particulars : — 



(1) the front is more prominent, so that the carapace is more 

 decidedly hexagonal : 



(2) the fronto* orbital border is sharply sexTated and the chelipedti 

 and legs are profusely spiny : 



(3) the external raaxillipeds do not completely close the buccal 

 cavern, but leave a wide gap between their anterior margin and the edge 

 of the epistome : 



(4) the dactyli of the legs are styliform.

Carapace and appendages in all the Indian species thickly 

 tomentose and hairy. 



Carapace deepish, either sabquadri lateral and a good deal broader 

 than long, or almost square, smooth, with little or no distinction of 

 regions, flat, but declivous anteriorly. Fronto-orbital border not much 

 less than, if not equal to, the gi-eatest breadth of the carapace : antero- 

 lateral borders short and if arched at all, very slightly so, and iisually, 

 but not always, with 2 or 3 teetli or spines. 



Front not well delimited from the supia-orbital angles, its free 

 edge deflexed and somewhat arched, never square-cut and laminar; 

 more or less distinctly bilobed. 



Upper border of orbit entire. The autennal flagellura, which is 

 of good length, stands in the orbital hiatus. The antenuules fold 

 transversely, or nearly so. 



MoutU and extei'ual luaxillipeds as in Uncratc, &c.
