flattened, not at all or only slightly raised above the level of the region of the fovea, its width always con- 
siderably less than that of the thoracic region and equal to the patella and 3 /s — % °f the tibia and to the 
tibia and 2 / 5 to nearly i /., of the metatarsus of first leg, and to the distance from the bottom of the fovea 
to some point in front of a transverse line passing midway between the posterior median and the posterior 
lateral eyes but posterior to a line touching the bind margins of the posterior median eyes. 
Posterior median eyes large, distant iy 5 — 1V4 of a diameter from each other and less than 2 diameters 
from the anterior lateral eyes (about a diameter of the latter eye less) ; centres of the anterior median eyes 
lying, if anything, a trifle below the level of the lower edges of the posterior medians (viewed from in front). 
Legs. All the femora densely clothed below with long fine hairs forming a mane ; no short spinules 
on underside of femora nor on anterior or undersides of trochanters or coxae. 
Pedipalps with some long spines amongst the hairs on innerside of the tibia and a number on 
inner and undersides of the tarsus; femur and patella without spinules. 
Chelicera and sternum without short sharp spinules on the surface. 
Vulva generally as in PI. XI, Fig. 9, the median septum between the emarginations somewhat 
variable, being sometimes slightly narrower and more rounded and sometimes more rectangular at the apex 
than in the figure, the lateral emarginations large but generally a little narrower than the median septum. 
Total length 14V2 — 18 mm; length of cephalothorax in largest $ (including ocular tubercle) 8V e mm, 
width of head 4 3 / i mm, of thorax 5V2 mm > distance from bottom of fovea to anterior surface of ocular 
tubercle 5V2 mm - 
b) I juv. ? from Kamaggas, Little Namaqualand, July 1904. 
The absence of spinules from the legs and sternum distinguishes this species at once from most 
other South African species. 
3. Eresus fumosus C. Koch. 
1837—1839 E. fumosus 0. Koch, Arach., Bd. IV, p. 100, fig. 314 (? from „Africa"). 
1865 E. lubo L. Koch, Verb. Zool.-bot. Gesellsch. Wien, Bd. XV, p. 878. (From Algoa Bay.) 
Specimens. I adult $ and 2 juv. from Port Nolloth, Little Namaqualand, April 1905. 
In this species the distance between the posterior median eyes varies considerably even in specimens 
from the same locality, being sometimes more and sometimes less than 2 eye-diameters apart. In this adult 
? of Dr. Schultze's these eyes are rather nearer together than is usually the case, being scarcely more 
than i 1 ^ diameters apart, but the shape of the vulva and the proportions of the cephalothorax agree with 
those of the numerous specimens of E. fumosus in the South African Museum from many other places in 
Cape Colony. 
E. Simon (Araign., 2nd ed., Vol. I, p. 252 and 253) states that E. bubo L.' Koch is the only 
Australian Eresid known and that its generic position, judging from Koch's figure, should be in Stegodyphu*. 
L. Koch, however, states in his description that the posterior lateral eyes are as far apart as the anterior 
lateral eyes, therefore it cannot be a Stegodyphus and moreover the locality, Algoa Bay, is in South Africa 
and not in Australia. There are several adult females of E. fumosus from Port Elizabeth (Algoa Bay) in the 
South African Museum, which entirely agree with L. Koch's description of E. bubo. It may be mentioned 
that several South African species of Myriapods of the genus Sjnrostreptus are also described from Algoa Bay 
in the same paper along with Eresus bubo, which fact should dispel any douht as to the locality of the latter.
