LINYPHIA. 
233 
The sexes are similar in colour, but the abdomen of the male is slenderer than that of 
the female, and its maxillae are slightly inclined towards the lip. The cubital and radial 
joints of its palpi are short, the latter being most produced at its extremity, on the inner side ; 
the digital joint is somewhat oval, with a large lobe on the outer side ; it is convex and hairy 
externally, concave within, comprising the palpal organs, which are highly developed, promi¬ 
nent, complex in structure, with a large process at their base consisting of three parts; the 
superior one, which is curved at its extremity, is in contact with the radial joint, on the outer 
side, and the other two are directed downwards, the one which is situated nearer to the 
inner side, and is the slenderer and more curved, having a projection on the outside of its 
curvature and another within, nearer to its base ; a short, prominent, curved process, whose 
point is in contact with a small, semitransparent membrane, occurs at the extremity of these 
organs, and their colour is red-brown of various shades. The convex sides of the digital 
joints are directed towards each other. 
Early in May, 1852, adult individuals of both sexes of Linyphia Meadii were taken by 
Mr. R. H. Meade, under a stone in a pasture at Low Moor, near Bradford.

Length of the female, ±th of an inch ; length of the cephalo-thorax, ^th, breadth, ^th; 
breadth of the abdomen, T gth; length of an anterior leg, 1th; length of a leg of the third 
pair, jjths. 
The legs are long, slender, provided with hairs and a few fine spines, and, with the 
palpi, have a bright, yellowish-red hue. The first pair of legs is the longest, then the 
second, and the third pair is the shortest; each tarsus is terminated by three claws ; the two 
superior ones are curved and slightly pectinated, and the inferior one is inflected near its 
base. The cephalo-thorax is oval, convex, glossy, with an indentation in the medial line; 
the falces are powerful, conical, armed with a few teeth on the inner surface, and inclined 
towards the sternum, which is heart-shaped, convex, and glossy; the maxillae are straight, 
with the exterior angle, at the extremity, curvilinear; and the lip, which is semicircular, 
is prominent at the apex. These parts are of a very dark-brown colour. The four inter¬ 
mediate eyes describe a trapezoid whose anterior side is the shortest, and those of each 
lateral pair are seated obliquely on a tubercle, and are nearly contiguous ; the anterior eyes 
of the trapezoid are the smallest of the eight. The abdomen is oviform, and of a glossy-
