cially on the anterior half. Abdomen pale-yellowish or faintly smoky, clothed with black hairs and uniform 
in colour. Chelicera with some basal white hairs. 
Cephalothorax as long 1 ) as the patella, tibia, metatarsus and l / 6 or slightly less of the tarsus of 
first leg, very high and rather broad, rising abruptly behind far above the fovea, its highest part lying 
behind its middle, the posterior part of the upper surface appearing convex, when seen from the side, the 
anterior part being flattened and sloping forwards ; width of head equal to the length of the patella, tibia 
and V3 of the metatarsus and to the tibia, metatarsus and y 4 °f tne tarsus of first leg and to the distance 
from the anterior surface of the ocular tubercle to the posterior margin of the fovea. 
Posterior median eyes large, about i 1 /., diameters apart and nearly 3 diameters from the anterior 
lateral eyes, a line touching the lower edges of the posterior median eyes passing below the centres of the 
anterior medians. 
Vulva as in PI. XI, Fig. 6. 
Total length 15 mm ; length of cephalothorax (including ocular tubercle) 6 mm, width 4% mm ; distance 
from centre of fovea to anterior surface of ocular tubercle 4 J / 2 mm. 
b) 10 juv. from Kamaggas, Little Namaqualand, July 1904. 
Allied to D. Inticeps Purc. (Trans. S. Afr. Phil. Soc, Vol. XV, p. 140, pl. 10, fig. 10, 1904) from

I $ from Kubub, Great Namaqualand, March or April 1904. 
Colour. Cephalothorax reddish-black, covered with olive-black hairs, the thoracic portion paler, 
reddish-yellow. Abdomen pale-yellow, with black hairs. 
Cephalothorax as long as the patella, tibia, metatarsus and l / i of the tarsus of first leg, shaped 
much as in D. namaquensis n. sp. ; width of cephalic portion equal to the length of the patella, tibia and 2 / 5 
of the metatarsus and to the tibia, metatarsus and l /. 2 the tarsus of first leg and to the distance from the 
anterior surface of the ocular tubercle to the hind margin of the fovea. 
Posterior median eyes large, slightly more than 1V2 diameters apart, and at least 3 diameters from 
the anterior lateral eyes; viewed from the front the centres of the anterior median eyes lie in (but not 
below) the line joining the lower edges of the posterior median eyes. 
Vulva as in PI. XI, Fig. 7. 
Total length i67 2 mm ; length of cephalothorax 7 mm, width 5V4 mm ; distance from anterior margin 
of ocular tubercle to centre of fovea 57c mm. 
Very near D. laticeps Purc. and D. namaquensis n. sp. 
3. Dreserus rostratus n. sp. 
PI. XI, Fig. 8. 
1 S from Southern Hereroland, September or October 1903. 
Colour. Cephalothorax blackish-red, covered with white hairs, except on the posterior slope of 
the cephalic portion, where the hairs are black ; legs dark reddish-brown, the distal segments dark-reddish, 
1) Length of cephalothorax is measured here between two parallel lines touching the anterior and posterior margins 
and including the ocular tubercle.
