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 in 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 maxillae are strong, convex underneath, and inclined towards the lip, which is semicircular
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 sid e ; 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 }th of an inch in diameter, and comprises about thirty spherical
eggs of a pale yellowish-white colour, not agglutinated together.

The cephalo-thorax is oval, convex, glossy, with slight furrows on the sides converging
towards an indentation in the medial line I the falces are powerful, conical, vertical, convex
in front' and armed with teeth on the inner, surface; the maxillae are enlarged at the base,
where the palpi are inserted, and inelined towards the lip, which is semicircular and
prominent at the apex ; and the sternum is heart-shaped. These parts are of a dark-brown
hue slightly tinged with red, the sternum, lip, and anterior part of the cephalo-thorax being
the darkest. The legs, which are robust, have a red tint, and the anterior and posterior
pairs are equal in len g th; 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; the cubital and radial joints are short, the former, which is the stronger,
being convex in front; the latter has two apophyses at its extremity; one, situated in
front, terminates in a point, and has a stnall,; acute process on the inner side ; and the other,
which occurs underneath, has a pointed process on the outer side; the digital joint is oval,
convex and hairy exterpally, concave within, comprising the palpal organs; these organs ate
highly developed, complicated in structure, with a corneous process at the upper part, curved
outwards and are of a dark red-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; and the colour of the branchial opercula is pale yellowish-white.
An adult male of this spider was discovered under a fragment of rock in a wood at
Oakland, in June 1835.
