The example from Omdurman has a more slender tail than 

 any of the original specimens.

Loc. Abu Haraz, Blue Nile [Capt. S. S. Flower) ; a small 

 male example measuring d)5 mm. in length. 



Remarks. — This example from the Blue Nile is a slight 

 variety of P. exitialis. The granulation of the under surface 

 of the humerus of the palp is very weak, except at tiie edges. 

 Four complete keels and a short inner keel are present on 

 the dorsal surface of the hand, and the tubercles are confluent 

 in places, but not nearly to the same extent as in tlie variety, 

 which I describe below under the name sudanicus. 



In his account of P. exitialis, Mr. Pocock says that there 

 is a single dry specimen from Schoa in the British Museum 

 collection. There are present, however, in the collection, 

 three dry examples (co- types) of this species, all of which 

 were collected by Sir \V. C. Harris at Schoa. Four com- 

 plete keels are distinctly visible on the hand of one of these 

 specimens, and traces of these keels can be seen in the other 

 two and in the variety from Gebel Mel. 



[Var. sudanicus, var. nov. 



This variety may be compared with the typical form of 

 the species (from Schoa) as follows : — Dorsal surface of 

 the hand much smoother, nearly the entire surface of the 

 lobe being furnished with low anastomosing ridges instead 

 of isolated tubercles (these ridges are smaller and narrower 

 than those of P. gregoryi, and they are finely, but distinctly, 

 punctured as in that species) ; the keels on the under surface 

 of the hand are more sparsely and weakly granular than 

 in the typical form. Proximal half of the under side 

 of the humerus granular as in the typical form. Tarsal 

 lobes of posterior legs with three spines, which are arranged 

 in the same way as in the typical P. exitialis; the total 

 number of spines on the anterior side of the tarsus is four, 

 and the total number on the posterior side six or seven. 

 Pectinal teeth twenty-one or t\\ enty-two in number. Last 

 abdominal sternite without any trace of keels. 



Measuremtnts in mm. — Total length 111 ; length of cara- 

 pace 18.
