Family CTENIZIDAE. 
Galeosoma Pallidum, sp. nov. 
Types. — Th ree adult female examples in tlie collection of tlie 
Transvaal Mluseum, taken pt Saltpan, Pretoria District, by the 
members of tlie Transvaal Museum Expedition, 6 X, 1914. The 
species is closelv related to G. schreineri, milii, from D^ Aar ( Records 
Albany Museum, Yol LI, p. 421), differing therefrom chiefly in the 
form of the shield. 
Colour. — Carapace palps and legs pale, yellowish; chelicerae 
brown ; abdominal shield black. 
Carapace subequal in length to the patella, tibia and metatarsus 
of the first leg 1 . Ocular area as wide as long. Hind margins of 
posterior row of eyes in a straight or slightly procurved line : distance 
between the posterior medians about 1J times the distance between 
posterior median and posterior lateral (in schreineri the posterior 
laterals are almost as far from the posterior median as the latter are 
from each other!. 
Leys. — Tibia II with 5 or 6 spines on its anterior surface, III 
with 5-9 spines on its posterior surface. 
Abdomen . — In its hinder portion the dorsal shield presents the 
appearance of a thick disk with sharply defined flat upper and fairly 
deep marginal inclined at right angles to each other, the junction 
between the two being a slightly upturned ridge : in its anterior half, 
however, the upper and marginal surfaces become more and more 
obtusely inclined to each other and their junction ill-defined, being 
marked by no ridge (in schreineri there is a continuous ridge quite 
devoid of pits all round) : moreover, the marginal surface anteriorly 
is a curved one and is considerably extended, much more so than in 
schreineri. The flat upper surface is approximately circular in out- 
line. Dor sally the soft skin immediately anterior to the shield is 
finely hairy, whereas in schreineri it presents 4 or 5 fairly regularly 
arranged transverse rows of closely approximated setae : these rows 
are visible to the naked eye as fine striae : in schreineri this arrange- 
ment is continued downwards along the lateral surface of the abdomen 
close to the shield and ends at the elongated ventral sigillum, but on 
the lateral surface the lines of setae are much more numerous and 
obliquely arranged, whilst the setae being much longer than those on 
the dorsal surface impart to the area a bearded appearance : nothing 
of this kind is found in pallidum. 
The first described species of this genus, G. scutatum, Purcell, 
taken at Krugersdorp, differs from pallidum as follows : posteromedian 
eyes nearer to each other than to the posterolaterals, the shield is 
strongly convex and nowhere flattened, being merely the hardened 
integument covering a portion of an abdomen of normal rounded pro- 
portions, but posteriorly it presents a slightly upturned thin edge, 
whilst elsewhere, except to a slight extent anteriorly, there is no 
indication of a marginal surface as distinct from an upper surface : 
lines of setae immediately adjacent to the shield on the upper and 
lateral surfaces are present, but not so strongly developed as in 
schreineri. 
Measurements. — Total length 21 mm., length of carapace T.4, 
breadth of same 5.8, greatest of shield 11 (measured from posterior
