A Survey of the Scorpion Fauna of Soidh Africa.

mens from Kakamas (Miss Olivier), which are referable thereto; the dark 
median stripe is not found in all specimens, however. Also known to me 
from North- West G-ordonia (C. Anderson), Kim})erley (Bro. J. H. Power) ; 
in some adult female examples from the latter locality the ])asal pectinal 
tooth is not enlarged. Some specimens from Pretoria (Gr. van Dam), from 
Pienaars River (Kimberley Museum), and a single male from Hopetown 
(Miss H. Stegmann), I also refer to this form. The Transvaal Museum has 
examples from the Pretoria neighl)ourhood, from Sterkstroom, and from 
G-roenkloof in the Rustenburg district. 
U. cariyiatus var. gracilior Hewitt (22) (Text-fig^s. 3 and 4), has the 
basal pectinal tooth of the female very f)road ; the fourth caudal segment 
of the male is slightly more than three times as long as l)road, in the feuiale 
about twice as long as broad. The types are from the neighbourhood of 
the Karasbergen in South-West Africa. 
This species is probably composed of a great number of local races ; the 
above-mentioned forms cannot be regarded as very rigidly separated from 
each other.

Distribution : According to Dr. Purcell this species extends from Cape 
Town to Mossel Bay and northwards into the divisions of Tulbagh and 
Worcester. Dr. Penther has recorded it also from Grrahamstown, but this 
is an error, I believe ; he may have confused the species with U.formnsus, 
which does occur near G-rahamstown.

Distribution : The type is from Port Natal, and the species ranges along 
the coastal districts from the neighbourhood of Port Elizabeth to Zululand 
and Eastern Transvaal, being known to me from Redhouse, Theescomb, and 
Walmer (Mrs. T. Y. Paterson), Fernkloof, Grahamstown (S. Juby), Pirie 
(R. G-odfrey), Mqanduli, Transkei (Miss A. Pegler), Kei Bridge (H. Kumm), 
Forbes Reef, Swaziland (Transvaal Museum), Mariannhill (Trappist Bros.), 
Port Alfred (J. Hewitt), Newington, East Transvaal (Dr. J. P. Fenoulhet). 
Kraepelin records it from Delagoa Bay. 
The number of pectinal teeth in ])oth sexes varies from 17-20, the basal 
tooth in the female being broader than and somewhat shorter than the rest. 
The secondary sexual differences are more pronounced than in Z7. lineatus. 
As in that species, the hand of the adult male is much stouter than that 
of the female ; but further, the sides of the fifth caudal segment of the 
male are much more strongly elevated than in the female. 
The characters of the fifth caudal segment seem to offer a certain means 
of distinguishing this species fi'om TJ. Uneaim. We have a single adult
