PHEYNICHUS. 127 



spines two or more rows deep, three of the spines of the front 

 row much larger than the rest ; femur long, cylindrical, a little 

 more than three times the median length of the carapace, but less 

 than twice its width, coarsely granular above, spined in front 

 above and below ; tibia about as long as the femur, coarsely 

 granular, armed at the distal end above with two long spines in 

 the adult, three in the young, and on the underside at the apex 

 with two smaller spines, the distal the smaller of the two, denti- 

 form and directed obliquely downwards and forwards ; hand smooth 

 externally and internally, granular above and below, the lower 

 edge being furnished throughout its length with two irregular 

 rows of coarse granules, armed above and below with a single long 

 spine, and also with a tubercle on its upper side at the base of the 

 spine. Second abdominal sternum furnished with a pair of semi- 

 lunar lobes ; first sternum transversely truncate in the middle of 

 its posterior border and furnished with a fringe of red hairs. 



(5 1 . First abdominal sternum widely rounded posteriorly and not 

 hairy. Chelce much longer than in j the trochanter and femur 

 generally much more hairy and much less strongly spined ; the 

 femur nearly four times the median length of the carapace. 



Youny much smoother than adult, more varied in colouring ; 

 the chelae considerably shorter, the tibia armed distally above with 

 three long spines, the first becoming gradually smaller with suc- 

 cessive moults until it is ultimately reduced to a mere tubercle. 



Total length up to about 30-35 mm.

$ . Size, colour, and general characters as in P. lunatus, f rom which 

 this principally differs in the permanent retention of characters 

 which appear in the young but are lost in the adult of that species. 

 For example, the first of the three large spines on the upper side 

 of the apex of the tibia of the chela is found in adult individuals 

 of P. phipsoni, and is about half the length of the others ; on the 

 lower side of the tibia in the distal fourth of its length behind the 

 two apical spines there is another spine, which is aKvays longer and 

 sometimes considerably longer than the rest ; the granulation of 

 the chelse is coarser and less close-set ; the underside of the hand 

 is smooth or almost smooth, with at most the merest trace of a few 

 granules ; and the distal inferior tibial spine is differently shaped 

 and less erect, its inferior edge being very decidedly convex from 

 base to tip, not straight with a median sinuosity as in P. lunatus, 

 and its upper edge lightly concave, without any basal convexity. 



Total length 28 mm
