hairy, provided with spines ; the latter terminated by a pectinated claw. 

 Last pair oflegs the longest, then the first, the third pair being the shortest. 

 The two superior tarsal claws are deeply pectinated, and the inferior one is 

 short and inflected at its base. These parts are of a dark reddish brown 

 colour, the legs, palpi, and nails of the mandibles being the reddest; the 

 anterior part of the cephalothorax, the mandibles, maxillae, and lip, which 

 are t|ie darkest, approaching to black. Abdomen oval and hairy, broader 

 at its posterior than at its anterior extremity, which projects, a little over 

 the base of the cephalothorax; its colour is yellowish brown with nu- 

 merous black spots above, and a black band, broad at the anterior part but 

 gradually becoming narrower as it approaches the spinners, extending 

 along the medial line; on each side of this band is a series of short, oblique, 

 yellowish brown lines, which, in some individuals, unite in the posterior 

 region of the abdomen, forming angles whose vertices are directed for- 

 wards ; a few minute, blackish spots occur on the under side of the abdo- 

 men. The plates of the spiracles are of a pale yellow colour. The superior 

 spinning mammillae, which are longer than the rest, rather prominent, and 

 triarticulate, have the spinning tubes disposed on the underside of the ter- 

 minal joint.

The male is similar to the female in colour, and in the relative length 

 of its iegs, but it is smaller, and appears to be much scarcer than that sex. 

 The third and fourth joints of the palpi are short ; the former has a large, 

 pointed apophysis on the outer side, and the latter is provided with two 

 apophyses, one on the outer side, which is acute, and the other in front, 

 which is obtuse and short ; the fifth joint is in the form of an elongated 

 oval pointed at the extremity; it is convex and very hairy above, concave 

 beneath, comprising the sexual organs, which are complicated in structure, 

 with a strong, curved spine on the inner side, and are of a red-brown co- 

 lour. 



I first observed this fine spider, which does not appear to belong to any 

 of the sections into which M. Walckenaer has distributed the genus Clu- 

 biona in the Faune Fran^aise, in the spring of 1826, on Snowdon, in Caer- 

 narvonshire, under loose fragments of rock ; and I have since met with it 

 in various parts of North Wales, and in Lancashire, under stones and in 

 the crevices of walls. It spins a compact web of small dimensions, from 

 which a tube extends to its retreat, and it preys chiefly on Coleoptera. In 

 the months of April and May it pairs, and the female deposits about a 

 hundred and twenty spherical eggs of a yellowish white colour, (which are 

 not agglutinated together), in a lenticular cocoon composed of white silk, 

 of a fine, compact texture, whose greatest diameter measures half an inch ; 

 it is usually attached to the under side of stones and fragments of rock, by 

 a small covering of web, on the exterior surface of which are frequently 

 distributed small bits of earth and other extraneous materials. 



Clubiona. parvula. 



Anterior part of the cephalothorax very convex above, depressed and 

 somewhat rounded in front; sides and posterior region depressed, the 

 former having several furrows diverging from the superior part to the mar- 

 gins, and the latter an indentation in the medial line; colour very dark 

 brown, five lines of white hairs, which unite at their extremities, occurring 

 on the anterior convexity ; the space below the eyes, and the base of the 

 snandibles, are also supplied with white hairs. The four intermediate eyes
