Measurements of adult female. Breadth of head-plate 14, length of patella 
of palp 12, of tibia and tarsus of palp 12-5, of patella of fourth leg ii-2, of 
tibia of fourth leg 10*1. 
A variety of this species, found at Umtali, was described by me under 
the name of 5 . serraticornis umtalica [Annals Transvaal Mus. iv. p. 162, 
fig. 24). We also have the species from a locality in the south of the Melsetter 
dist. (F. A. O. Pym). 
In umtalica the upper margin of the basal enlargement of the flagellum is 
curved: there are numerous well-feathered bristles on the lower jaw, and the 
distance from the tip of the fang to the apex of the first tooth is equal to i^-if 
times the distance between the two large teeth : there is a dense group of long 
and strong spines on the upper and outer surfaces of the chelicera.

p. 304, fig. 1. 
The type came from Shilowane, near Leysdorp. What seems to be the 
same species was described by Mr S. Hirst from the Zoutpansberg dist., under 
the name of S. pugilator {Ann. Mag. Nat. Hist. 8, ix. p. 232). It is known to 
me from Newington (Dr J. P. Fenoulhet), and the Transvaal Museum has it 
from Hectorspruit (F. Streeter), and Griffin Mine, Leysdorp (G. van Dam). 
In this species the form of the basal enlargement varies somewhat. In the 
Newington specimen the upper margin of the basal enlargement is quite long 
and practically straight : in the Griffin Mine example it is a little shorter, and 
distinctly curved on the upper margin. Moreover, in the latter, the terminal 
portion of the shaft beyond the sinus is not so sharply pointed nor so straight 
as in our Newington example. The Griffin Mine form is presumably typical: 
that from Newington and Hectorspruit is apparently the same as pugilator 
Hirst, which may thus rank provisionally as a varietal form. 
The characters of the lower jaw, however, seem to separate these forms 
a little further: in the Newington example, the fang is distinctly longer than 
in other specimens, the distance from the tip to the apex of the first tooth 
being equal to 1^ times the distance between the apices of the two large teeth, 
whereas in examples from Griffin Mine and Hectorspruit the proportion is 
if times. In each case there are numerous well-feathered bristles on the 
lower jaw. 
A female example probably referable to spiralicornis was also taken at 
Griffin Mine by Mr van Dam : I refer it to this species, rather than to monteiroi, 
which was taken in the same neighbourhood, on account of the dark pigmen- 
tation on the abdomen, a character found in the male of spiralicornis. The 
soft skin between the tergites of the abdomen and thorax is rather deeply 
infuscated, and on the abdomen this extends to some extent down the sides 
in the neighbourhood of the first three or four segments : in the hinder half of 
the abdomen the soft skin of the sides is deeply infuscated over an extensive 
area and also ventrally between the sternites. The head-plate is brown, dark 
brown near the anterior margin, the ocular tubercle very darkly so. Palps 
and legs pale yellowish brown. Malleoli not infuscated. There are two inter- 
mediate teeth of moderate size in the single series of the upper jaw.
