The following species of Hadogenes 
are known to 
occur in the 
Transvaal : — 
H. gunningi Pure., Pretoria neighbourhood. 
H. granulatus Pure., Rustenburg District, male only known. 
H. bicolor Pure., Zoutpansberg District, female only. 
H. gracilis , sp. nov., with distribution as above. 
Also probably H. troglodytes Pet. and perhaps H. betschuanicus 
Pent, described from British Bechuanaland. 
The species are easily distinguished by the characters of the caudal 
segments. In H. gracilis the caudal segments are longer and more com- 
pressed from side to side than in any other species known to me. 
HADOGENES GUNNINGI PURC. 
This Transvaal species of Hadogenes was described by Dr. Purcell 
in the Annals of the South African Museum, 1899, vol. 1, p. 435, 
from several female specimens. 
The male resembles the female in colour and other general 
characters, but differs in that it is of more slender build, the tail in 
particular being considerably more elongated ; also the last abdominal 
tergite is relatively longer and narrower. 
Tail six times as long as the carapace, which is as long as the first 
together with one-fifth of the second caudal segment. Terminal tooth 
of superior crests enlarged and practically spiniform in caudal 
segments 2 and 3 (enlarged also in segment 4 of our largest specimen) ; 
the superior keels slightly denticulate in segments 2 and 3, more so 
in segments 4 and 5.
