a. The single series of teeth in the upper jaw comprises two large 
ones in front, one small intermediate tooth, followed by a large tooth. 
D. hottentotta Kraepelin. 
b. Dentition similar to that of hottentotta but two small intermediate 
teeth in the single series. D. pearsoni Hewitt. 
c. The single series of teeth in the upper jaw comprising one small 
one in front, then a large one, then a small intermediate tooth, and 
finally a large one. D. lineata Pocock. 
4. Terminal fang of moderate length. Flagellum attenuated distally 
but not produced into a long shaft. Basal tooth of lower jaw with a 
broad more or less truncated apex. In the upper jaw, the longest and 
largest tooth is separated from the distal tooth by a deep bay : 
a. This bay including one small tooth. 
D. betschuanica Kraepelin. 
b. The bay being quite toothless. D. rhodesiana Hewitt. 
5. Terminal fang of upper jaw specially long, followed by a single 
series comprising only two teeth, both of which however are large. 
Flagellum continued beyond the capsule into a short dorsal process and 
a longer ventral one, connected together by a fold of membrane, the 
latter process being less than half the length of the capsule. 
D. schultzei Kraepelin.

Types from Dunbrody, Uitenhage div., and the species is also known 
to me from Alicedale (F. Cruden), Somerset East (E. Driver), and Linedrift, 
Peddie (B. Marais). 
In the male the head-plate is beset with short spinules, but each eye is 
protected on its mesial side by a curved row of upstanding spines: the 
chelicerae have numerous, rather short, sharp pointed, stout spines and a few 
long ones superiorly, and the thoracic tergites are also fringed with pointed 
spines: abdominal tergites with very short spines and weak spinules, the 
posterior one or two tergites with slender setae which are slightly notched at 
the tips: a few spines occur on the upper surfaces of the trochanters and 
femora of legs II-IV. 
In the females of unguicornis , and probably of other species also, the head- 
plate is armed with short spinules or prickles, and the tergites and chelicerae 
with spines : these spines are not so strong nor so numerous as those of the 
male, the first tergite for example having a single row of long slender spines 
in the female, but far more numerous, shorter and much stouter spines, 
constituting more than one row, in the adult male.
