three claws ; the two superior ones are curved and pectinated, and the inferior one is inflected 
near its base, where a pair of fine teeth is situated. The palpi resemble the legs in colour. 
The abdomen is oviform, thinly covered with hairs, convex above, projecting over the base of 
the cephalo-thorax; the upper part has a dark-brown hue, a series of strongly marked, 
yellowish-brown, angular lines, whose vertices are directed forwards, extending along the 
middle; the colour of the sides and under part is pale, yellowish-brown, the latter having a 
band of a deeper shade in the medial line; the superior spinners are much longer than the 
rest and triarticulate, with the spinning-tubes distributed on the inferior surface of the 
terminal joint, which is whitish, the remaining portion of these spinners and the whole of the 
others being of a brown colour; the sexual organs have a dark, red-brown tint; and that of 
the branchial opercula is whitish. 
The sexes are similar in colour, but the male is rather the smaller. The cubital and 
radial joints of its palpi are short; the former has a slender, curved process on the outer side 
of the upper part, and the latter projects one which is longer, slenderer at its termination, 
and more curved, from a prominence or apophysis at the outer side of its extremity; the 
digital joint is oval, convex and hairy externally, concave within, comprising the palpal 
organs; they are moderately developed, not very complicated in structure, prominent at the 
upper part, nearly encircled by a fine, black spine, and of a pale, red-brown colour. 
Agelena prompta is included by M. Walckenaer among the synonyma of Tegenaria 
emaciata (‘Hist. Nat. des Insect. Apt./ tom. iv, p. 462), from which species it differs in size, 
organization, and colour. It conceals itself under stones in woods about Llanrwst, and the 
male has the palpal organs completely developed in October.

The eyes of each lateral pair are seated on a small tubercle, and are nearly contiguous ; 
they are the largest, and the intermediate ones of the anterior row are the smallest of the 
eight. The cephalo-thorax is glossy, slightly compressed before, and rounded on the sides, 
which are depressed, and marked with furrows converging towards a narrow indentation in 
the middle ; the falces are strong, conical, and inclined towards the sternum, which is broad 
and heart-shaped; the maxillm are short, gibbous at the base, round at the extremity, and 
slightly inclined towards the lip, which is nearly semicircular. These parts are of a brown
