single white spot above the spinnerets. In the femjale there are 
some white scales at the front end, one, two, or three pairs 
of oblique white bars on the middle of the back, a white spot on 
each side, low down, at the posterior end, and a single white spot 
just in front of the spinnerets. In the male the first legs are 
dark, excepting the metatarsus and tarsus which are pale 1 , and 
there is a single fringe of dark hairs on the femur and a double 
fringe, also dark, on the tibia. The other legs are pale, more or 
less distinctly marked, with two longitudinal dark lines. In the 
female the legs are of medium brown. The falces project a 
little, and are brown in color, as are the mouth-parts and ster¬ 
num, but the coxae are pale. 
This species, which closely resembles C. australis, is very 
common in South Africa, and we have many specimens from 
Algo a Bay, Cape Colony and Mashonaland.

The cephalothorax is high, with the cephalic plate inclined 
forward. The thoracic part slopes very little in the first half, 
and then miueh miore abruptly. The sides slant outward but 
little, and are plainly widest behind the dorsal eyes. The quad¬ 
rangle of the eyes is a little wider in front than behind, is 
one-fourth wider than long, and occupies two-fifths of the 
cephalothorax. The front eyes are a little separated and form 
a curved row. The lateral eyes are rather small for this genus, 
but are more than half as large as the mjiddle eyes. The sec¬ 
ond row is a little nearer the first than the third, and the third 
is almost as wide as the cephalothorax. The sternum is rounded 
behind and truncated in front. The anterior coxse are sepa¬ 
rated by more than the width of the labium, which is as wide 
as long. The elypeus is one-half as wide as the middle eyes. 
The falces are vertical, and rather long and stout. 
The upper part of the cephalothorax is covered with bright 
red hairs, A curved white band, just below the eyes, runs
