being the case especially in the ? ), its anterior crest distinct, with 

 a second, generally less distinct, parallel crest behind it. Hand 

 smooth, but often with traces of a few weak granules anteriorly, 

 slender, its width about equal to that of the tibia in the 2 and 

 immature <? , but stout and about Ij times the width of tibia in the 

 ad. $ ; the length of movable finger in the $ about 2|-, in the ad. ^ 

 l|-lf times the length of the hand-back ; movable finger with 16-17 

 anterior flanking teeth, the main rows in the middle third of the 

 fingers composed of 6-9 teeth (including the enlarged basal one),, 

 the anterior flanking granule often situated considerably distal to 

 the line joining the middle and posterior granule of the obliquely 

 transverse rows of 3. 



Pectines with 26-31 teeth in the ? and with 29-34 in the 3" ; the- 

 posterior basal lamella of the scape very similar in both sexes, the 

 posterior inner angle in the ^ , although rounded, generally move 

 prominent and the posterior edge somewhat longer than in the ? , 

 the latter edge bearing 1 or at most 2 teeth, which are always- 

 elongate and occupy less than half of the posterior side; this 

 lamella in the ? bearing 1 or no teeth, the basal pectinal tooth 

 in this sex always strongly abbreviated and generally represented 

 by a short conical or even spherical stump, scarcely distinct from 

 the small fulcra at the bases of the teeth.

A darker variety, ajpparently identical in colouration wdth P. ful- 

 vipes (Sim.) and not differing in structure, except in some unimportant 

 points, from the specimens just described, inhabits Great Bushman- 

 land and adjacent districts to the east. In these the tru.nk is nearly 

 always dark brown to almost black and generally with a greenish 

 tinge, the posterior caudal segments often darker than the anterior
