seen from the side) basal portion, produced at its upper anterior 

 angle into a long, slender, toothless, terminal fang. This fang is 

 almost straight and subulate, very slightly sinuous above in the 

 middle and again below at the apex, and is slightly inclined outwards 

 from its base ; it forms an angle of about 150 with the upper surface 

 of the mandible ; its outer surface is convex but the inner surface 

 is deeply sulcate throughout its length. The anterior almost trun- 

 cated surface of the basal portion of the jaw is sinuate in the upper 

 part and nearly at right angles to the fang, while in the lower part it 

 is furnished with a double row of teeth, the outer row being com- 

 posed of 4 teeth, the second tooth being very small. Lower jaw 

 slender, curved strongly upwards towards the apex, provided with 2 

 long and rather slender sharp teeth with a minute denticle between 

 them. 



Flagcllum composed of a transparent, pear-shaped, flattened disc, 

 drawn out behind into a straight subulate shaft, which exceeds the 

 disc in length and is directed backwards and slightly upwards. The 

 disc is attached, scale-like, to the inner surface of the mandible at its 

 upper edge just behind the base of the fang in such a manner that 

 the lower half and the upper edge of the vertical disc is free, the 

 edge projecting slightly above the upper surface of the mandible.

Characters of the South African Species. Tarsi of II. -IV. legs 

 two-jointed, with very long, strongly diverging, sub-ungual appen- 

 dages (fig. 136). Tarsus of I. leg with 2 small but distinct claws in 

 both sexes. Short stout spines occur only on the II. and III. legs, 

 viz., 1 at the apex of the tibia and 3 on the upper side of the meta- 

 tarsus (in C. incrmc these spines are very weak) ; long spiniform 

 setifi occur on the legs and palps, those on the under side of the tibia 

 of the latter arranged in two distinct series (sclateri, capense) or more 

 irregular (inerme). Tarsus of palp immovably fused to the meta- 

 tarsus, the latter (fig. 13ft) cylindrical or very slightly depressed from
