The antennules fold transversely in narrow fossss. 



The antennal flagella short. 

 » Epistome o£ fair length fore and aft, well demarcated and never 

 encroached upon by the external maxillipeds. 



Buccal orifice quadrate, a little elongate and a little bit rounded 

 and contracted at the anterior angles. 



Legs gressorial. 



Sternum broad. 



The Telphusidae are the highest Cyclometopes, and approach the 

 Catometopa. They appear to me, from consideration both of structure 

 and of habitat, to have branched off from the Oziine or Eriphiine stocks, 

 but are now inhabitants of fresh- water or damp jungle. 



I do not propose to treat this family further, in this series of 

 papers, until I have finished the other Brachyura. 



Family II. XiNTHiDiE. Carapace transversely oval, or transverse- 

 ly hexagonal, or subquadrilateral, or (rarely) subcircular, but almost 

 always broader than long ; the regions very often, but by no means 

 always, well defined and multi-areolate. Front broadish or very broad, 

 oftener than not it is not sharply separated from the supra-orbital 

 angles, often obliquely deflexed, usually showing a division into two 

 lobes (each of which may, in some cases, show a farther subdivision 

 into two lobules). 



The antennules fold either quite transversely or obliquely trans- 

 versely. 



Antennal flagella short or slender. 



Epistome of fair length fore and aft, well demarcated, not en- 

 croached on by the external maxillipeds. 



Buccal orifice quadrate, commonly broader than long. 



Legs gressorial. 



Sternum moderately broad — much narrower than in the Telphu- 



I have already in this Journal, Yol. LXVII, part 2, 1898, pp. 

 69-233, dealt with the family Xanthidm in detail. 



The family is there divided into the following 7 sub-families : —
