of the glossy portion, the two surfaces blending in the hind quarter of the 
shield. At the sides, the glossy portion is obliquely inclined in relation to the 
dull basal strip or to the upper surface with which latter it forms an obtuse 
angle. The upper surface of the shield is almost completely devoid of hairs: 
several occur on the lateral edges and one or two on the internal portions of 
the surface. The glossy part of the marginal surface is also devoid of hairs 
except in its posterior half where basally a fairly dense group of bristly hairs 
occurs on each side. Dorsally, the soft skin of the abdomen immediately 
anterior to the shield presents several transverse rows of closely approximated 
short fine setae and ventrolaterally in the immediate neighbourhood of the 
shield there are numerous obliquely arranged lines of setae. 
Measurements. Total length 16, length of carapace 7, breadth of carapace 
5 -2, length of shield measured along the upper surface 8*4, breadth of shield 
measured across upper surface 6-3, anterior depth of shield 1-4, posterior depth 
of shield 1-4, greatest depth of shield (measured about the middle point of its 
length) 2-2. 
The adult specimens from Papai are noteworthy in that the glossy lateral 
and posterior surfaces of the shield are completely devoid of hairs which is not 
the case in any of the Mazambo examples. 
Galeosoma planiscutatum sp. nov. (text fig. 4 d). 
The types of this form are four rather small female examples from Buffels- 
draai, Pretoria dist., collected by Mr A. Roberts (17. iv. 1916). These specimens 
are without doubt adult, although considerably smaller than the adults of 
other known species. The form of the shield of any species though very con- 
stant in adult specimens collected in one locality, may vary considerably 
according to the maturity of the individual and eventually it may be found 
impossible to distinguish between the various species except in the fully adult 
stages. The species here described belongs to the group which includes palli- 
dum, pilosum and hirsutum. 
Shield. The upper surface is broadly oval or almost round in outline and 
quite flat, except near the margin where it is strongly upturned all round : it is 
fairly regularly covered with shallow punctuations the largest of which are a 
pair situated at points about one-third or two-fifths of the total length distant 
from the posterior end, the distance between these sigilla being about half the 
distance of either from the margin of the surface or at any rate not so great as 
that distance : anteriorly, there may or may not be another pair of sigilla but 
in any case they are not so distinct, their distance apart being equal to or 
somewhat greater than their distance from the posterior pair but much greater 
than their distance from the margin of the surface. The general surface carries 
numerous short fine setae but no long ones: on the upturned edge however 
there are longer stifhsh setae. The marginal surface is fairly uniform through- 
out, being pitted and somewhat roughened, not polished: in the anterior half 
it is hairy, but only very sparingly so in the posterior half except just at the 
posterior extremity: it is for the most part at right angles to the upper surface 
except posteriorly where the two surfaces are more acutely inclined to each 
other. The depth of the marginal surface is relatively small and is least 
posteriorly. In front of the shield superiorly the soft skin of the abdomen 
presents well defined rows of setae. 
Carapace. There is a very long stiff bristle arising from between the antero- 
median eyes, a pair of shorter and weaker ones between the posteromedians, 
a single weak one just behind the frontal eyes, and a pair of long ones behind
