carapace is nearly Hat, not divided into regions, and marked only by the 

 crescendo cervical groove where it defines the mesogastric region, and by the 

 ftiint, post-frontal mesogastric groove. 



The front is deflexed, square-cut, and of great breadth, considerably more 

 than two-fifths the greatest breadth of the carapace, the unique specimen 

 being apparently an old male. 



There is a small lateral epibranchial tooth. The epigastric and post- 

 orbital crests, though very faint, are quite apparent, and are oblique. The 

 length of the 6th abdominal segment of the male equals its distal breadth. 



The antennal flagellum is vestigial. The exopodite of the external 

 maxillipeds is flagellate ; the ischium is not longitudinally grooved ; the 

 merus is broader than long, and has its antero-external angle very square-cut. 

 The mandibular palp has the terminal segment bifurcate from the base. 



Only one cheliped is present ; it is quite smooth, has the inner angle of 

 the carpus rounded off, a high inflated palm, and toothless fingers, the dactylus 

 being curved strongly, and meeting the fixed finger only at tip. 



The legs are stout, with peculiar long sparse bristles, chiefly on the 

 posterior part of the propodites. 



The carapace is ^ inch long, and jths inch broad.

Subgenus VI. — Globitelphusa. 

 Type : Globitelphusa bakeri, Alcock. 



The species in this subgenus resemble Liotelphusa in the indistinctness of 

 the epigastric and post-orbital crests and of the lateral epibranchial spine of the 

 carapace ; indeed, in most of the species these parts are more obscure than in 

 any Liotelphusa; but along with this character the exopodites of the external 

 maxillipeds are either devoid of a flagelhmi, or have a mere papilla-like vestige 

 of one. 



As in all the subgenera, except Paratelphiisa itself, the antero-lateral 

 borders of the carapace are not cut into spines, and there is no subterminal 

 spine on the upper border of the merus of the chelipeds. 



The cervical groove, as in Phricutelphusa and Liotelphusa, is well cut only 

 where it defines the mesogastric area posteriorly — elsewhere it can not be, or 

 can hardly be, traced. 



This group consists of two sections. In one of them the species are very 

 small and have a squarish carapace, which may either be tumid, as in Liotel- 

 phusa, or flattish, as in Phricotelphusa. The species of the other section have a 

 carapace which for breadth and convexity rivals that of Gecarcinucus — these
