But although there is thus a possibility o£ resuscitating Harpax- 

 theria, it must be remembered that the apparently greater narrow- 

 ness of the cephalothorax in P. belandana may be due to artificial 

 shrinkage, and that too great stress should not be laid upon the 

 tibial spine-armature, seeing that iu the male of P. gregorii, which 

 is apparently congeneric with P. antUope and P. ocn'dentalis, the 

 tibia of the 1st leg is armed with 5 spines, the 2nd with 3, and the. 

 3rd and the 4th w ith 2 each. 



Again, before Harpaxotlieria be rescued from the world of syn- 

 onyms, it will have to be ascertained that it is distinguishable from 

 Karscli's previously established genus Pelinolnvs, a poiut about 

 which great doubt may be entertained.

2 . Colour. Integument of carapace, mandibles, and legs uniform 

 deep reddish brown, covered with deep olive-green hairs ; the 

 distal segments of the palpi and of the tirst two pairs of legs much 

 redder in the young ; femora, patella?, tibiae, and yirotarsi with a 

 fringe of yellowish-pink hairs at their distal extremities ; abdomen 

 greenish brown; the long bristles on the legs and abdomen reddish. 



Carapace considei'ably longer than patella and tibia of 4tb and 

 2nd legs, a little longer than those of 1st, longer than tarsus and 

 protarsus of 4th, much longer than those of 1st, a little lunger 

 than patella, tibia, and tarsus of palp ; its width a little less than 

 the area between the posterior emargination and the ocular tubercle, 

 much exceeding the 4th protarsus and just exceeding protarsus 

 and tarsus of 1st leg, a little longer than femur of 4th leg. 



Legs 4, 1, 2, 3 : 4th exceeding 1st by one fourth the length of its 

 tarsus ; tibiae with a pair of distal spines below, protarsus of 1st 

 with 1 median apical spine, of 2nd with 3 spines, of 3rd and 4th 

 with about 9 spines iu a transverse row. 



Measurements in irdllimetres. — Total length 62 ; length of cara- 

 pace 32, width 26 ; length of palp 47, of 1st leg 78, of 2nd leg 69, 

 of 3rd leg 63, of 4th leg 79, patella and tibia of 1st 30, of 4th 27, 

 protarsus of 4rh 21 (legs and palpi measured from base of femur). 



In younger females the legs are much longer as compared with 

 the carapace than in the adult. 



Loc. Benito River ((?. L. Bates). 



This species has not been hitherto recognized since it was first 

 established. 



It certainly differs from P. belandana Karsch (Berl. euti. Zeit. 

 1884, p. 348), from NiamNiam in Central Africa, in having only a 

 pair of spines at the apex of the tibiae, instead of a large number as 

 in P. helanduna ; that is to say, 9 on the 1st tibia, 8 on the 2nd, &c. 

 In P. belandana also the sternum is nearly twice as long as wide 

 (15 : 8), whereas in P. occidentalis the length is only a little greater 

 than the width (9 : 7"5). In the characterof the sternum P. occiden- 

 talis resembles P. hUttneri Karsch (Berl. ent. Zeit. 1886, p. 83), from
