LINYPHIIDiE. 
black hue, with an obscure series of angular lines of a yellowish-brown colour, whose vertices 
are directed forwards, extending along the middle of the upper part; it is sparingly supplied 
with hairs, convex above, and projects over the base of the cephalo-thorax ; the sexual organs 
have a dark-browm hue; a prominent process is connected with their anterior and another 
with their posterior margin; the former, which is much the larger, is nearly semicircular, 
concave within, and has a longitudinal septum in the middle ; the posterior one is somewhat 
enlarged at its extremity, and directed obliquely backwards. 
The sexes are similar in colour, but the figure of the male is slighter than that of the 
female; there are some fine bristles, directed forwards, on the middle of the anterior part of 
its cephalo-thorax, and the falces have a small protuberance in front, near tbe base. The 
palpi are short, and of a bright, yellowish-red colour, with the exception of the digital joint, 
which has a dark-brow T n hue; the radial is stronger than the cubital joint, and is rather 
produced in front; the digital joint is somewhat oval, with a lobe on the outer side, near the 
base ; it is convex and hairy externally, concave within, comprising the palpal organs, which 
are highly developed, prominent, complex in structure, with two contiguous, curved spines 
. near their middle, a compressed, curved process at the base, on the outer side, a pointed one 
on the inner side, and are of a red-brown colour. 
This species varies greatly in colour; some individuals have the yellowish-brown, angular 
lines extending along the middle of the upper part of the abdomen very distinctly marked ; 
others have the ground-colour of the abdomen yellow-brown, and the angular lines black ; 
and occasionally specimens may be found with the abdomen of a uniform black, or yellowish- 
brown hue. 
The original description of Linyphia Claytonice was made from adult males received from 
Miss Ellen Clayton, who took them near Garstang, in Lancashire. In 1852, Mr. R. H. Meade 
captured adult females at Bradford, in Yorkshire, which were described as a distinct species, 
under the name of Linyphia anthracina; however, a careful examination of both sexes, found 
in considerable numbers in the summer of 1860 by the Rev. O. P. Cambridge, at Bloxworth, 
in Dorsetshire, has served to establish the fact that they are specifically identical.

The four intermediate eyes describe a trapezoid whose anterior side is the shortest, and 
those of each lateral pair are seated obliquely on a tubercle, and are almost contiguous; the 
posterior eyes of the trapezoid are the largest, and the anterior ones much the smallest of 
the eight. The cephalo-thorax is oval, convex, glossy, with an indentation in the medial
