Galeosoma pilosum, sp. nov. (Plate XXVI, figs. 5, 6, and 7.) 
| Types. — Aperies of adult female specimens from Mavville, Wonder- 
boom Poort, Pretoria College, Koedoespoort, Garstfontein, and Lyttelton 
Junction, localities all in the neighbourhood of Pretoria, collected by 
Messrs. G. van Dam and A. Roberts (March-April, 1915). This form 
is undoubtedly closely related to pallidum from Saltpan, and perhaps 
should be placed as a variety thereof : the forms pallidum , pilosum , 
hirsutum , and coronatum, constitute a gradational series, and though the 
two extremes differ greatly it would be difficult to separate them 
specifically without also assigning specific distinction to the intermediate 
forms which moreover are fairly sharply defined. 
Abdominal shield resembling that of pallidum in shape, but covered 
with rather long hairs. Upper surface flatfish and usually sub-rotund 
in outline : posterior edge broadly rounded, quite sharp, and a little 
upturned, anterior edge ill-defined or obsolete. Marginal surface 
posteriorly only faintly pitted, as a rule, but occasionally rather coarsely 
pitted. The skin on the upper surface of the abdomen immediately 
anterior to the shmld carries no such rows of setae as occur in schreineri, 
but there are a number of long rather sparsely distributed setae, like the 
hairs on the shield : such setae do not occur in pallidum. 
Carapace with a number of long bristly hairs on the raised head region 
dorsolateraily and also between the eyes of the posterior group, a 
specially long one projecting forwards between the anteromedian eyes. 
Measurements. — Total length 19 mm., length of carapace 7 -6, breadth 
of carapace 6, diameter of circular margin of upper surface of shield about 
7 -8, depth of marginal surface measured on mid-line anteriorly about 
4 -75. 
In the newly-hatched young of this species there is no trace of an 
abdominal shield : the abdomen is purplish dorsally and shows indication 
of a number of white cross stripes. 
It may be noted that four pairs of sternal sigilla are sometimes present 
in this species, the two posterior pairs being very small. 
A small character, but a very constant one in this form, is the sharp 
posterior '-:dge of the upper surface of the shield : the anterior edge of 
that surface is a very variable character, sometimes being carried forwards, 
so that the upper surface becomes a little elongated and the marginal surface 
anteriorly considerably reduced. In a young specimen from Garstfontein 
the edge of the upper surface is ovoid in shape, and very sharp and 
upturned throughout : the two surfaces are thus very strongly marked off. 
Two other examples in which the line of junction between the two surfaces 
is formed by a sharp continuous ridge were taken at Lyttelton Junction : 
in these specimens, which are considerably smaller than an average adult 
-of pilosum, the upper surface is sub-rotund in outline. 
Galeosoma hirsutum, sp. nov. (Plate XXVI, figs. 1 and 2). 
Types. — A series of female examples from Roodeplaat and from 
Zeekoegat, near Pretoria, collected by Messrs. G. van Dam and A. Roberts 
(1st and 2nd April, 1915). 
Abdominal shield . — The upper surface is decidedly convex and is 
oval in outline, the marginal surface in the mid-dorsal line anteriorly being
