Length of the female, §ths of an inch; length of the cephalo-thorax, |rd, breadth, 7 3 5 ths ; 
breadth of the abdomen, |ths ; length of a posterior leg, l T 3 5 ths ; length of a leg of the third 
pair, 1 loth. 
This spider ranks among the largest British species. The lateral eyes of the anterior 
row are the smallest, those constituting the anterior pair of the trapezoid are the largest, and 
each eye of the posterior pair is seated on a tubercle. The cephalo-thorax is compressed 
before, depressed and rounded on the sides, hairy, with furrows converging from the lateral 
margins towards the middle, and a longitudinal indentation in the posterior region ; its colour 
is dark-brown, a yellowish-brown band extending along each side. The falces are powerful, 
conical, armed with teeth on the inner surface, and of a dark, reddish-brown colour. The 
maxillm are strong, and, with the lip, are of a reddish-brown hue. The sternum is heart- 
shaped and somewhat paler than the maxillae. The legs are robust, provided with hairs and 
spines, and are of a reddish-brown hue, being palest underneath; the fourth pair is the 
longest, the second rather surpasses the first in longitudinal extent, and the third pair is the 
shortest; each tarsus is terminated by three claws; the two superior ones are curved and 
pectinated, and the inferior one is inflected near its base. The palpi resemble the legs in 
colour, and have a curved, pectinated claw at their extremity. The abdomen is oviform, 
densely covered with hairs, convex above, projecting over the base of the cephalo-thorax; it 
is of a dark-brown colour on the upper part, with an obscure row of whitish spots on each 
side of the medial line, which are sometimes obliterated, and a longitudinal band of a 
yellowish-brown hue on each side; the under part is of a deep, yellowish-brown colour ; and 
the sexual organs have a dark, reddish-brown tint. 
In the earlier periods of its existence, the legs and palpi of this species are of a dull- 
greenish hue, the cephalo-thorax and upper part of the abdomen are of a dark, olive-brown 
colour, and the lateral bands are white.
