horizontal or slightly slanting downwards ; they are of about even width 
throughout their length or very slightly broader at the back. The nests, 
from which the males were taken, were very narrow at the entrance, .and 
much broader and flatter at the back. 
The following are measurements of a typical nest of a female : — 
Width at the entrance (inside edge) 6 mm. 
Width at the bottom of the tube 7 mm. 
Breadth of lid 6J mm. 
Length of lid (front to back) 6J mm. 
Thickness of lid § mm. 
Breadth of hinge 4 mm. 
Accmthodon paucispinulosus Hewitt. 
Locality : Gravelotte. 
Notes and measurements were not made at the time of discovery of 
this species ; but the nests were very similar to those of A. transvaalensis . 
Acanthodon, cp. grandis Hewitt. 
Localities : Forbes Beef, Swaziland, and Lochiel, Carolina District. 
The Forbes Beef specimens were taken from nests situated either in 
banks of red clay or under the shelter of rocks ; some of those from the 
banks had an enormous number of young. They were cleverly disguised 
to assimilate with the red soil and sometimes with moss, according to where 
they were situated. The nests found under the rocks were smaller than 
those from the banks and the specimens seem to be adult ; their nests 
were vertical, with the lids disguised to assimilate with the soft dry mixture 
of earth and old vegetable matter found under the rocks. Nests from 
Lochiel varied considerably ; thus, one taken from the bank on the side 
of a road was very shallow, only about 2 inches deep and horizontal in 
position ; whereas the others normally slanted downwards and were about 
4 or 5 inches deep. In some cases the lid was hinged on the lower edge 
of the entrance, so that when opened it stood out like a platform below 
the entrance. 
Acanthodon , cp. oomi Hewitt. 
Localities : Lake Chrissie, Tevreden, and Oshoek, Carolina District. 
Numerous nests were taken near Lake Chrissie, all of them situated 
on the upper face of the bank on an old road. Some of them contained 
young. The lids in every case were covered with bits of grass, the first 
part of the tube standing out from the bank, and the whole outward 
appearance reminding one very much of the nests of Galeosoma pilosum 
and G. hirsutum. The tube was never very deep, only about 3 inches. 
Acanthodon schreineri , Purcell, var. minor Hewitt. 
This new variety was first discovered amongst stones on a kopje at 
Boodeplaat, Pretoria District. The nests were distinct from any previously 
found in the district, being characterized by peculiar double lids. Part 
of the tube projected above the ground for about a quarter to half an inch ;
