Length of the female, |th of an inch ; length of the cephalo-thorax, nth, breadth, 55 th, 
breadth of the abdomen, nth; length of an anterior leg, |th; length of a leg of the third 
pair, yth. 
The legs, which are robust, are provided with hairs and fine spines, and the anterior and 
posterior pairs are equal in length; each tarsus is terminated by three claws ; the two 
superior ones are curved and deeply pectinated, and the inferior one is inflected near its base ; 
the palpi have a curved, pectinated claw at their, extremity; the cephalo-thorax is oval, 
convex, glossy, with furrows on the sides converging towards an indentation m the medial 
line; the falces are powerful, conical, convex in front, near the base, armed with a few small 
teeth on the inner surface, and slightly inclined towards the sternum, which is heart-shaped, 
the maxilhe are strong, convex underneath, and inclined towards the lip, which is semiciicular 
and prominent at the apex. These parts are of a red-brown colour, the lip, maxillae, falces, 
and anterior part of the cephalo-thorax being the darkest. The abdomen is oviform, convex 
above, projecting over the base of the cephalo-thorax, and is rather broader at the posterior 
than at the anterior extremity; it is thinly clothed with hairs, glossy, and of a yellowish- 
brown colour tinged with black; and the branchial opercula have a pale-yellow hue. After 
the female has deposited her eggs the abdomen acquires a brown-black tint. 
The male is smaller and darker coloured than the female. The humeral joint of its 
palpi is curved towards the cephalo-thorax; the cubital and radial joints are short, the latter 
having two obtuse apophyses at its extremity, the larger situated on the outer and the 
smaller on the inner side; 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 dark red-brown colour. 
This species is plentiful in the valley of the Conway, where it conceals itself under 
stones; and in December, 1848, an adult male was received from Mr. J. Hardy, who took it 
in Berwickshire. In July the female spins several globular cocoons of white silk of a slight 
texture, attaching them to some depression in the stone selected for her retreat; the largest 
of these cocoons measures of an inch in diameter, and comprises about thirty spherical 
eggs of a pale yellowish-white colour, not agglutinated together.
