sculpturatus (PI. XXVII, fig. 66) occurs at Groenkloof , Eustenburg District, 
and the Transvaal Museum has a similar variety from Arthol, Ermelo 
District. This variety connects together the typical jonesi and anthracinus. 
It is possible that sculpturatus and anthracinus will be found to merge 
together ; according to our material, large specimens of the two forms are 
well separated in the character of the superoanterior crest of the humerus, 
which is strong in anthracinus but weaker in sculpturatus, and moreover, in 
sculpturatus the sides of the fifth caudal segment are not granular. 
It seems probable also that the typical form of jonesi will prove to be 
directly connected with crassimanus.

Distribution : Type from Lydenburg and known to me also from 
Machadodorp (Brit. Mus. Coll.). 
Key to the Species of the Genus Cheloctomis. 
1. Humerus with a distinct superior crest in front ; upper surface 
of hand more or less rounded and forming a very obtuse angle 
with the hand-back ; hand and brachium closely and finely 
punctured, sometimes obsoletely so^, the general surface almost 
smooth but reticulately marked ; carapace finely granulated 
almost throughout, without extensive smooth areas ; sides of 
fifth caudal segment with scattered fine granules or some- 
times almost without granules . . . . . C. crassimanus Poc. 
la. Upper surface of hand flattened ; sides of fifth caudal segment 
free of granules ..... C crassimanus depressus var. nov. 
2. Differs from crassimanus thus : " Upper side of brachium and 
hand much more coarsely sculptured, ornamented with thick 
smooth ridges and scarcely visibly punctured." The carapace 
granulated almost throughout, without smooth areas except 
immediately in front ; sides of fifth caudal segment with 
scattered, comparatively coarse, granules. General colour 
black ; vesicle ferruginous ...... C. anthracinus Poc. 
3. Differs from crassimanus thus : Upper surface of hand flatter, 
forming an angle of about 110° with the hand-back ; carapace 
with extensive smooth punctured areas, its anterior portion 
being almost quite free of granules except near the median 
eyes ; supero-anterior crest of humerus more acute . . C. glaher, Krpln. 
4. Humerus without a superior crest in front ; upper surface of 
hand smooth and rounded; fifth caudal segment without 
granules at the sides, or only finely granulated, and the upper 
surface not grooved mesially ....... C jonesi, Poc. 
4a. Similar to typical form of jonesi, but differing as follows : Hand 
and brachium much more coarsely sculptured above, being 
ornamented with thick, smooth ridges forming a coarse net- 
work ; humerus with a low but distinct supero-anterior crest
