Trapp's Valley : Total length 74, length of movable finger 10-7, of hand-back 
9-3, breadth of hand 8-5. 
This form differs from the Natal variety chiefly in the armature of the 
tarsi. It is known to me from the following localities : G-rahamstown, Pt. 
Alfred (W. Tooke), Kleinemonde (Mrs. O. White), Trapp's Valley (W. 
Cronwright), Fort Brown (C. Mally), Pirie (Rev. E. Grodfrey), East London 
(J. Wood). The East London form approaches tyijicus in that there are 
generally stout bristles at both angles of the tarsi, but the hand is much 
smoother than that of tyjncus. 
" (b) 0. validus Y^v.fulvipes Pocock (PL XXVIII, fig. 77). The type was 
taken in Basutoland (8) and what seems to be this variety is known to me 
from Ladybiand (Dr. T. F. Dreyer), from Tayatazaneng (British Museum), 
from the Burghersdorp District (Dr. E. Broom) from Majuba Nek, Herschel 
District (J. Hepburn), and from Memel between Vrede and Botha's Pass 
(E. Bader). The crest on the inner margin of the upper surface of the hand 
is a fairly constant character but the Burghersdorp specimens are scarcely 
distinguishable from alhanicus in that respect. There is no median row of 
spicules on the lower surface of the tarsi between the two rows of spines. 
The vesicle of the male has four rows of granules inferiorly, the inferolateral 
rows being cjuite distinct though weak ; in the female the inferolateral rows 
are absent or indistinct. The shape of the vesicle is probably not so 
constant as its granulation ; it is not very deep in the male from Memel. 
(c) 0. validus var. transvaalicus Kraepelin. — This was described (13) as 
a distinct species, the type being merely located " Transvaal." It is described 
as having a bristle at the terminal angle of the tarsus inferiorly, but I have 
no hesitation in referring to this variety a large series of adult specimens 
from Doornkop near Belfast in which usually a spine occurs at that angle, 
although in some specimens there is a bristle instead. It is also known to 
me from Wakkerstroom (A. Eoberts). In the Doornkop material a median 
row of spicules is present on the lower surface of the tarsi but sometimes 
may be only feebly represented ; the spicules are absent from the Wakker- 
stroom specimen. In the latter, the upper surface of the hand is sculptured 
throughout, whereas Doornkop specimens have the hand practically smooth 
in the middle above. 
This variety is closely related to fulvipes, and indeed I have previously 
referred the Doornkop material thereto (19). 
Prof. Kraepelin has recently described (13) what I suspect to be a form 
of validus under the name of 0. minor. The type is labelled Frenchhoek 
(Paarl District), but at the same time another specimen of the same form is 
recorded from Mpome (Transvaal). Now it is highly improbable that the 
local form at Frenchhoek can be the same as that at Mpome, and seeing that 
the description agrees in almost every respect with our Doornkop series I am
