The anterior eyes of the four intermediate ones forming the trapezoid are the smallest of 
the eight. The cephalo-thorax is oval, convex, glossy, with a slight indentation in the medial 
line ; the falces are strong, conical, vertical, armed with teeth on the inner surface, and have 
a small, conical process towards the inner side of the extremity, in front; the maxillse are 
powerful, greatly enlarged where the palpi are inserted, and inclined towards the lip, which 
is semicircular and prominent at the apex ; the sternum is broad and heart-shaped. These 
parts are of a reddish-brown colour, the falces and maxillse being the reddest. The legs have 
a pale-red hue, and the anterior and posterior pairs are equal in length; 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, with the exception of 
the digital joint, which has a reddish-brown tint; the cubital and radial joints are short; the 
former is very strong and convex in front, and the latter projects three apophyses from its 
extremity; the largest is situated on the outer side, the next on the inner side, and the smallest 
underneath; the digital joint is oval, convex and hairy externally, concave within, comprising 
the palpal organs, which are highly developed, complicated in structure, and of a reddish- 
brown colour. The abdomen is oviform, convex above, projecting over the base of the 
cephalo-thorax; it is thinly clothed with hairs, glossy, and of a brownish-black hue, the colour 
of the branchial opercula being yellowish-white. Some individuals have the abdomen of a 
yellowish-brown hue. 
The female is rather larger than the male. The anterior part of its cephalo-thorax is 
tinged with brown, and its abdomen, which is of a dark-brown hue on the upper part, has a 
brownish-yellow band extending along the middle, which is crossed, about one third of its 
length from the anterior extremity, by a somewhat obscure band of the same hue; the colour 
of the under part is brownish-yellow, and that of the sexual organs is dark, reddish-brown. 
Adult males of this species occur in May and June among rank herbage growing m 
woods about Llanrwst, and in 1840 specimens of the same sex were obtained by Miss Ellen 
Clayton near Garstang, in Lancashire. 
In the summer of 1860 both sexes, in a state of maturity, were found near Hendre House, 
and also at Bloxworth, in Dorsetshire, by the Rev. 0. P. Cambridge.
