the inferior median 7 . ft 7 a- not differentiated amongst the coarse gran uli a 

 covering tin lower surface of th, segment', 5th segment with the 

 inferior keels denticulated, t lie area between them coarsely granular; 



upperside of the 3rd, 4th, and 5th segments smooth, the keels 

 also smooth or at all events only roughened with pores ; vesicle 

 granular, narrow, its width equal to its height and only about 

 one-third the length of the vesicle and aeuleus. 



Chela : humerus coarsely granular above, its anterior surface with 

 strongly granular crests; lower surface granularly crested behind; 

 brachium finely granular in front, also roughened with pores and 

 granules behind; hand wide, its width about equal to the 1< 

 of the movable digit, its upper surface smooth posteriorly on the 

 lobe, the area just above external keel coarsely granular, the rest 

 co\ered with low more or less anastomosing tubercles, which are, 

 however, more distinct towards ihe base of the immovable digit ; 

 the inner edge smooth, though the granules of the lower surface 

 run right up to it or even project slightly beyond it : the lower 

 surface sparsely granular, with two weakly defined keels; keel 

 defining the hand-back above very strong and prominent. 



Legs smooth ; protarsal segment of 1st and 2nd with a single 

 external apical spine; tarsi armed with eight spines, two on each 

 side being on the lobe, one un its lower angle, the other in the 

 middle as in P. col i, P. belUeosus, <.v.c.

Recognizable by the granulation of the lower side of the 4th
