the female, and its cephalo-thorax, legs, palpi, falces, maxillae, and lip, are of a red colour, 
slightly tinged with brown. The cubital and radial joints of its palpi are short, the latter 
being much the stronger, and somewhat produced in front; the digital joint is of an irregular 
oval form, having a large lobe on the outer side ; it is convex and hairy externally, concave 
within, comprising the palpal organs, which are highly developed, prominent, complicated 
in structure, with a curved, pointed process, enveloped in semitransparent membrane, at the 
extremity, and a large one at the upper part, consisting of two branches; one, directed 
upwards, extends nearly to the articulation of the radial with the cubital joint, and the other 
is directed downwards; both are pointed and curved outwards, an obtuse prominence occur¬ 
ring near the base of the latter, within the curve; these organs are of a reddish-brown 
colour. The convex sides of the digital joints are directed towards each other. 
By the structure of its oral apparatus and by the disposition and relative size of its 
eyes this spider makes a near approximation to the Liniphyce. It was taken under stones at 
Crumpsall Hall, in October, 1836.

Length of the female, | 5 ths of an inch; length of the cephalo-thorax, fdh, breadth, ^th ; 
breadth of the abdomen, ^th; length of an anterior leg, 1th; length of a leg of the 
third pair, J,ths. 
The legs are moderately robust, and provided with hairs and a few fine spines ; the 
first pair is the longest, then the fourth, 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. These organs, with the palpi, have a red tint. 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, divergent at the 
extremity, armed with teeth on the inner surface, and slightly inclined towards the sternum, 
which is heart-shaped; the maxillae are strong, and inclined towards the lip, which is semi¬ 
circular and prominent at the apex. These parts are of a red-brown colour, the falces, lip, 
and margins of the sternum being the darkest. The eyes are seated on black spots ; the 
four intermediate ones form a trapezoid, whose shortest side is before, those of the anterior 
pair being the smallest of the eight. 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 ; a large, prominent, curved process, of a red-brown colour, connected with the 
anterior margin of the sexual organs, is directed backwards, and the branchial opercula have 
a pale-yellow tint. Some individuals have the abdomen of a yellowish-brown hue, and 
the other parts generally lighter coloured.
