Annals of the Transvaal Museum. 
This species has a very pronounced and objectionable odour, recalling 
that of decomposing stable manure. The type is in bad condition, as it 
seems to have been moulting at the time of capture. Another example 
was subsequently taken by Messrs. Roberts and Van Dam between Yilliera 
and Derdepoort, near Pretoria (12th April, 1915). It is smaller than the 
type, but otherwise agrees well therewith. In this specimen the maxillary 
processes are dark-brown : the dentition (text fig. 3, No. 2), is clearly 
referable to two main series, the inner distal one including only two teeth. 
On the other hand, in a specimen from Hatfield the teeth are in a single 
series. 
I have little doubt but that this species is closely related to and 
perhaps even identical with C. simoni Poc., which, however, was founded 
on a very much larger specimen (length of fang 8, of carapace 10). The: 
original description of that species merely states that the first and second 
legs are “ as in C. fulvipes Lucas,” and as Mr. Pocock’s description of 
fulvipes in the “ Fauna of British India : Arachnida ” (p. 160) states 
that “ the legs of the posterior pairs are furnished distally with a few 
spinules 55 and makes no reference to the occurrence of spinules on the 
anterior legs, one might reasonably infer that the first and second pairs, 
of legs in fulvipes and in simoni are muticous. However, Mr. S. Hirst 
has very kindly supplied me with a description of the spinulation of the 
second leg in the type of simoni, as follows : — “ Patella with a longitudinal 
series of fine long hairs on its upper surface and 3 or 4 short bristles or 
spinules at the apical end ; a number of spinules at the distal end of the 
tibia forming a narrow transverse strip (the spinules being 2-3 deep), or 
only strongly developed in the middle, also in this segment there are a 
few lateral setae ; there are numerous spinules distributed throughout 
the upper surface of the metatarsus, and others are present on the outer 
side of this segment, but are longer, weaker, and less numerous ; tarsus 
with weak spinules.” From this account it would appear that the spinu- 
lation of tibia II is more pronounced in ransvaalicus than in simoni, and 
in the latter species, apparently, there are no spinules at the base of that 
segment superiorly. 
The large size of the posterior sternal sigilla will perhaps distinguish 
it from fulvipes as figured by Pocock, but the constancy of this character 
is doubtful : in the Hatfield specimen the sigilla are about a diameter 
apart, but only half a diameter from the margin of the sternum.

Acanthodon transvaalensis (Hewitt). (Text fig. 4.) 
Female specimens of this species were collected by Messrs. A. Roberts 
and G. van Dam at the following localities in the Pretoria District during 
April, 1915 : Mayville, Rietfontein (Pretoria), Witfontein, Skinner’s Court,, 
between Lyttelton Junction and Irene, Rietfontein (20 miles north-west 
of Pretoria), Schoemansrust, Roodeplaat, and Zeekoegat in the same 
neighbourhood. 
The type of this species is evidently immature, and Mr. A. Roberts 
has taken very much larger specimens near Pan Station, Middelburg, and
