are the typical forms. It might be advisable to separate these two sections, 

 but I leave them together for the present. 



The species of the " subgenus " may be tabulated as follows : — 



I. Carapace strongly convex, almost cylindrical ; much broader than long : — 



i. Side-walls of carapace smooth; flagellum of first and second niaxil- 

 lipeds vestigial : — 



1. Epigastric crests hardly distinguishable . . . P. Ixikeri. 



2. Epigastric crests visible as two isolated lumps . . . /'. ci/liiidnix. 

 ii. Side-walls of carapace rugulose ; flagellum of first and second maxil- 



Ii]ieds well developed . . . . . .P. pixlorica. 



II. Carapace squarish, flat or moderately convex, little broader than long. 

 (Quite small species) : — 



i. Carapace flat ; front, in adult, about two-fifths the greatest breadth 

 of the carapace ; 5th abdominal segment of the adult male much 

 broader than long : — 



1. Fingers of chelje pointed ; dactyli of legs of normal length and 



hairiness . . . . . . . /'. gnhenmtons. 



2. Fingers of chelae spoon-tipped ; dactyli of legs short and very 



hirsute . . . . . . . . 1'. pilusipes. 



ii. Cara])ace convex ; front, in adult, half the greatest breadth of the 

 carapace ; .5th abdominal segment of the adult male longer than 

 broad ......... P. fronio. 



40. Paratelphusa (Globitelphusa) bakeri, Alcock. (Fig. 30.) 



Carapace broad, very convex, subcylindrical, its length between two-thirds 

 and three-fourths its greatest breadth, its depth exceeding half its length, its 

 surface everywhere smooth, its regions barely distinguishable. Even the side- 

 walls of the carapace are smooth. 



The cervical groove is distinct only where it bounds the mesogastric area 

 posteriorly. The post-frontal mesogastric groove is superficial and very 

 indistinct- — only just visible. 



Front in adult from one-third to two-fifths the greatest breadth of the 

 carapace, square - cut, almost vertically deflexed, nearly straight - edged. 

 External orbital angle insignificant, the upper and lower borders of the orbit 

 meeting almost flush at that point. 



Antero-lateral borders of carapace well arched, blunt for the most part, 

 but well enough defined. There is the merest trace of a lateral epibranchial 

 denticle, and it is apjDroximated to the orliit. Postero-lateral borders rather 

 strongly convergent. 



Epigastric crests recognisable, but very indistinct ; the post-orbital crests 

 are more distinct especially in their outer half, which curves forward. 



In the abdomen of the male the 5th segment is short and broad, the 6th 

 has convergent sides and its length barely equals its distal breadth, the 7th has 

 a broadly-rounded tip and is very much longer than broad. 



Antennal peduncle small and impacted ; the flagellum short.
