inclined to ignore the record of the type locality, as being possibly erroneous, 
and to unite minor with transvaalicus. Strictly speaking, the name minor 
has priority over transvaalicus but in view of the uncertainty regarding the 
type specimen of the former I shall for the present employ the latter name, 
0. diremptus Karsch, which Kraepelin originally referred to the synonymy 
of validus but now maintains as a distinct species, is stated to be founded on 
very young examples, and as the locality data are very indefinite I think it is 
undesirable to maintain the name. 
(d) 0. validus var. nov. laevis. — The types of this variety are eight 
specimens in the Transvaal Museum from the Drakensberg in Basutolai|^l. 
The hand is very like that of the Doornkop variety, the upper surface being 
smooth to a considerable extent and not depressed, a more or less distinct 
keel arising from the base of the immovable finger to form the inner bound- 
ary of the upper surface. The vesicle is quite smooth inferiorly in both 
sexes. The fifth caudal segment is granulated laterally. At the angles of 
the tarsus inferiorly is a pair of spines and in addition there are usually 
3'2 spines but in one case 3* 3 and in another example 2*2 ; there is no 
median row of spicules between the two rows of spines. Male with 6 
pectinal teeth, females usually with 5, but in one example 6*5. General 
colour brown, the legs being yellow. Male 42 mm. long, female 55. 
This small variety may perhaps prove to be linked up completely with 
transvaalicus. 
(e) Lastly, a pair of specimens from Forbes Reef, Swaziland, also in the 
collection of the Transvaal Museum, seems to represent another distinct 
form which I now name as 0. validus y?iy. nov. swazianus. The hand is very 
like that of validus tyjpicus, being coarsely reticulated throughout, not 
smooth in the middle, and without a distinct keel forming the inner margin 
of the upper surface. The fourth tarsus has spines at the angles inferiorly, 
and there is no median row of spicules below. The vesicle of the male is not 
deep and swollen, but has a strongly developed infer omedian pair of granular 
rows, and in addition the inf erolatei al rows are quite distinct, though^the 
individual granules are weak ; in the female the inferolateral rows are 
obsolete and the inferomedians somewhat less strongly developed than in the 
male. The sides of the fifth caudal segment are finely roughened in the 
male, nearly smooth, but not entirely so, in the female. Greneral colour 
blackish, legs dark. Total length of female 70 mm. 
The Durban Museum has a female specimen from Utrecht which seems 
to be referable to this variety. 
This form agrees with Kraepelin's description of minor except in the 
absence of a keel on the inner margin of the hand.
