400 Annals of the South African Museum. 



Palps with the metatarsus and tarsus stout, straight, and equally 

 thick throughout. Armature of the legs and palps and the shape 

 and colouration of the sub-lingual appendages as in sclatcri. I. leg 

 as in sclaterl. 



Mandibles very bristly, with a dense cluster of reddish bristles on 

 the inner side towards the apex. Terminal fang of upper jaw long 

 and slender, very curiously shaped and divided into two portions : 

 the basal portion, commencing on a level with the first tooth of the 

 inner series and forming about two-fifths of the length of the fang, 

 is hairless, yellowish, slender, almost cylindrical and sharply marked 

 off from the rest of the jaw ; it is directed forwards ; the distal 

 portion of the fang is a continuation of the median half of the basal 

 portion, the lateral half of the latter terminating abruptly, as if the 

 fang had been transversely cut half-way through its thickness from 

 the lateral side and then the lateral portion of the distal part sliced 

 off by a longitudinal vertical cut (fig. 15ft). The distal portion of 

 I lie fang is dark red and is bent sharply outwards from the base, so 

 strongly that it forms a right angle with the corresponding portion 

 of the other jaw ; it is further twisted on its axis so that what is 

 outer surface proximally becomes upper surface distally, while in the 

 region of the twist this surface is strongly concave ; the upper 

 margin is, moreover, strongly compressed and forms a sharp-edged 

 keel, which terminates abruptly in an angle at the twist. Dentition 

 of the upper jaw composed of a posterior double series of 3 outer 

 and 3 inner, small, separate teeth, the single series in front of 

 these represented by a low black crenular keel under the basal 

 portion of the fang, but without any separate teeth ; the distal 

 portion of the fang without teeth. Lower jaw strongly curved up- 

 wards and outwards at the apex and provided with 2 large teeth and 

 1 small one between them ; in one jaw there is another very minute 

 denticle in front of the small tooth ; the terminal fang is simple.
