13. Anterior median eyes about a diameter apart and three or 
more diameters distant from the anterior laterals which are 
of moderate size. The patch on Coxa III includes 12-16 
spinules. (Alicedale.) M . rupicola, Hewitt. 
14. Anterior median eyes about half a diameter apart, and about 
two diameters distant from the anterolaterals, which are 
small being' hardly twice the area of the anteromedians. 
Patella III with several rows of stout spiniform setae 
anteriorly, and with 1-3 short spines on the distal edge. 
Patch on Coxa III including about 30 spinules. (Grrahams- 
town.l M. rupicoloides , Hewitt. 
15. Anterior median eyes about a diameter apart and about two 
diameters or a tribe more distant from the anterior laterals, 
which are of moderate size, their area 3 or 4 times that of an 
anterior median. Patch on Coxa III including about T or 8 
spinules. Patella III with a band of 8 or 9 spines along its 
anterior surface. (Prom 50 miles south of ITmtali.) This 
species differs from the type of M. whitei, Poc., from the 
Hyika plateau as follows : anterior lateral eyes in whitei 
distant about 2 diameters from anterior margin of carapace 
or very nearly so, in pymi rather less than a diameter distant 
from that margin. In whitei there are only about 10 spinules 
in the cluster on Coxa III, that of II including about 14 
spinules : the labium has many strong spinules. 
M. pymi , Hewitt. 
{c 2 ) Fovea with a very distinct broad but short backward prolongation 
in the midline. 
16. Anterior median eyes slightly more than half a diameter apart 
and distant about 1J diameters from the anterior laterals, 
which are small, being about twice the area of a median. 
The patches of spinules on Coxae II and III are large. 
Patella III with a broad anterior band of spines and short 
spiniform setae. (Alicedale.) M. terrestris, Hewitt. 
(d) Coxae /, II, and III each with a basal patch of spinules inferiorly. 
{d 1 ) Fovea without a backward prolongation in the midline. 
IT. Patch of spinules on Coxa III including only about 5-10 
spinules. (Grahamstown, TJitenhage, Somerset East.) 
M. dyeri, 0. P. Camb. 
( d 2 ) Fovea with a very distinct broad but short backward prolongation 
in the midline ( sometimes wanting, hoivever, in breyeri.) 
18. Carapace with a distinct protuberance on each side in a line 
with the anterior bend ot the fovea and a little near to the 
side of the carapace than to the fovea. Distance between 
anteromedian and anterolateral eyes about equal to diameter 
of former, the laterals very large. (Gravelotte, near Leyds- 
dorp.) M. breyeri, sp. nov. 
19. Carapace without a protuberance on each side lateral to the 
fovea. Distance between anteromedian and anterolateral 
eyes about equal to three times the diameter of the former, 
the laterals comparatively small. (Alicedale.) 
M. crudeni, Hewitt.
