This species was described from a single mutilated male 

 brought by M, d'Arnauld from the banks of the White Nile 

 (" du fleuve Blanc "). I am not aware that it has been 

 recorded since from any locality ; consequently the capture 



of two adult male examples by Mr. and Mrs. E. Lort Phillips 



is of great interest. 



Rhax ornata, Poc, PhiUipsti, subsp. n. 



Closely resembling R. ornata, Poc.f, from Mombasa, in 

 size and colour, but differing in the following particulars:^ 

 The colour of the trunk is identical in the two, except that in 

 R. Phillipsii the antero- lateral angles of the carapace are 

 broadly fulvous, whereas in R. ornata only the border is of 

 this colour ; the mandibles are a uniform reddish brown, and 

 not yellow above and black at the sides, as in ornata; the 

 legs are almost wholly fulvous, the black bands present in 

 R. ornata being represented by very faint spots; and, lastly, 

 the protarsus of the palp is a uniform reddish brown through- 

 out, whereas in ornata it is yellow at the base and black in 

 its distal two thirds. 



A single male example was obtained: 



Biton hrunnipes, sp. n. (PL XL figs. 4, 4a.) 



Colour. — Head brownish, pale in the middle; thoracic 

 terga pale ; abdominal terga brownish ; mandibles yellowish, 

 with two brownish bands on their upperside ; palpi with 

 femur distally brownish, the apex only pale ; patella with its 

 two extremities pale, the rest brownish ; tibia coloured like 

 the patella, but darker, tarsus dark yellowish ; first, second, 

 and third legs almost entirely pale, fourth leg with distal half 

 of femur, whole of the patella, and proximal half of tibia 

 brownish black ; coxal areas of cephalothorax entirely pale 

 yellow. 



Caropace elevated, hairy ^ anterior border moderately convex; 



* According to Mr. Lort Phillips, these Arachnids are known to the 

 Arabs bv a name which may be spelt " Gailvbogs."
