A Survey of the Scorpion Fauna of South Africa. 143 
coarse granules ; in the female the first 4 sternites are quite smooth. 
The hand of the female is covered above with low anastomosing coarse 
tubercles, especially on the inner surface basally, or with isolated coarse 
tubercles, the finger keel more or less completely broken up, the secondary 
crests well developed or at any rate distinct ; that of the male has the upper 
surface covered with low coarse tubercles of irregular shape, but isolated for 
the most part and not closely compacted, the finger keel strong, more or less 
■completely broken up or smooth over a considerable distance in its distal 
portion, the secondary keels strongly developed. 
Measurements (of an adult male and female from Pretoria) : Total length 
M. 75, F. 82-5 ; length of carapace M. 10, F. 12 ; breadth of carapace M. 
10"5, F. 11"4 ; distance of median eyes from anterior edge of carapace M. 6*3, 
F. 7-8 ; width of hand M. 8.25, F. 10-2 ; length of handback M. 5-5, F. 6.5 ; 
length of movable finger M. 1075, F. 11*5 ; length of tail M. 39'4, F. 36-6 ; 
width of first caudal segment M. 5*4, F. 5'2 ; width of fifth caudal segment 
M. 4, F. 3-3. 
0. latimanus var. austeroides Hewitt (PI. XXIV, fig. 48). 
Distribution : The types (Hewitt 21) are from Klerksdale near Middel- 
burg. Cape Province. The elongation of the humerus and of the hand in 
the adult male is a distinctive feature of this form. From austerus Karsch, 
it may be distinguished as follows : Humerus of male shorter than the 
carapace, terminal tooth of superior crests in caudal segments III and lY 
not spiniform, fewer pectinal teeth (M. 16-18, F. 13-14). In the types, the 
total length of which is M. 89, F. 90, the length of the carapace is M. 13, 
F. 13-4 and of the humerus M. 11-8, F. 9-8. 
I regard this form as intermediate between typical latimanus and 
austerus. 
A similar but smaller variety is known to me from Herschel, and a male 
specimen from Burghers dorp in the collection of the British Museum is very 
near austeroides, but the hand is not quite so elongated. 
0. latimanus var. heilandsi Hewitt (PI. XXIV, figs. 49 and 53). 
Distribution : The types (Hewitt 21) are from Keilands, Cape Province, 
This may possibly be same as 0. ])raedo Thorell (1) a form which I am 
obliged to discard owing to the uncertainty of its position : see Purcell (15). 
Kraepelin (10 and 11) and Penther (26). 
0. latimanus var. natalensis Hewitt (PI. XXIII, figs. 42 and 43). 
Distribution : The types (Hewitt 24) are from Estcourt and Mooi Eiver, 
Natal. It is a stouter form than heilandsi. This is the form recorded by 
Pocock from Estcourt and Durban under the name of ]pugnax ; the Durban 
record requires confirmation.
