New South African Trap-Door Spiders. 355 
Abdomen sparsely tuberculate above. 
Measurements.--Total length 20; length of carapace 84, width 
6°6 ; length of tibia of first leg 3-4; width of ocular area 1°8. 
This species may possibly be the 9 of cregoez, in which, however, 
the outer margins of the anterior median eyes are as far apart as 
those of the posterior median eyes and almost as far apart as those 
of the anterior lateral eyes. 
The nest, which was also obtained by Dr. Kolbe, is tubular, about 
10 mm. in diameter throughout its greater part, but at about 10 mm. 
from the opening it commences to widen gradually and reaches 
15 mm. at the opening. The edges of the tube expand horizontally 
at the opening and form a broad rim about 4 mm. wide round two- 
thirds of the circumference. The lid is flat and not thickened, merely 
closing against the rim. The hinge is very broad, being nearly as 
broad as the greatest diameter between the outer edges of the rim. 
Greatest width of lid (taken parallel to hinge) 24 mm., least width 
(at right angles to hinge) 17 mm., width of hinge 20 mm.
