Length of the female, tth of an inch; length of the cephalo-thorax, ^th, breadth, T ',th ; 
readth of the abdomen, ^th; length of a posterior leg, 1th ; length of a leg of the second 
pair, 1th. 
The legs are robust, hairy, and black, with reddish-brown annuli, on which white hairs 
occur; the fourth pair is much the longest, and the first, second, and third pairs are nearly 
of equal length, the second pair being rather the shortest; each tarsus has two long, curved 
pectinated claws at its extremity. The palpi are short; they resemble the legs in colour, and 
t le radial and digital joints are abundantly provided with long, white hairs. The cephalo- 
thorax is nearly quadrilateral; it slopes abruptly in the posterior region, and the anterior part 
is prominent, projecting beyond the falces ; above it is clothed with black hairs interspersed 
with yellowish-white ones, which, in some individuals, form an obscure spot between the 
posterior pair of eyes. The falces are small, vertical, armed with a few minute teeth on the 
inner surface, and are of a dark, reddish-brown colour. The maxilke and lip have a dark 
brown hue, their extremities being the palest. The sternum is oval, with a small prominence 
on each side of its anterior part; it is sparingly supplied with white hairs, and is of a dark- 
rown hue. 1 he abdomen is ovate, hairy, somewhat depressed, pointed behind, and projects 
over the base of the cephalo-thorax; above it is of a brownish-black colour, blended with white 
and on each side of the medial line, rather nearer to the posterior than the anterior extremity 
there is a conspicuous, irregular, white spot, between which and the spinners there 
is a series of obscure, whitish lines, of an angular form, whose vertices are directed 
orwards, and a white spot is situated immediately above the spinners; a tuft of white hairs 
occurs at its anterior extremity, and the sides have a grayish tint, with a few white spots in

The male does not differ from the female in the relative length of its legs, and it resembles 
er in colour; but its abdomen is smaller in proportion to the size of the cephalo-thorax The 
cubital and radial joints of the palpi are short; the latter projects two obtuse apophyses from 
its extremity, one situated in front, and the other, which is much the larger, on the outer 
side; the digital joint is oval, convex, and hairy externally, concave within, comprising the 
palpal organs, which are highly developed, not very complex in structure, and of a dark red- 
brown colour. ’ 
Specimens of this spider were captured on the outer walls 
Manchester, in the summer of 1828. It pairs in the month of May.
