LINYPHIIDiE. 
is fringed with long hairs on the outer side; the digital joint is oval, convex and hairy 
externally, concave within, comprising the palpal organs • these organs are highly developed, 
complicated in structure, with a prominent, curved, scale-like process on the inner side, 
which terminates in a point directed obliquely downwards and outwards, and a spiral spine 
at their extremity, at whose base there is an expanded, projecting, transparent membrane, 
slightly fringed at its margin; they are of a brownish-black colour. The legs of old males 
are frequently of a red hue, without annuli. 
This species constructs snares, similar in design to those of the Linypliia, among grass 
growing in and near woods in Lancashire, Denbighshire, and Berwickshire. It has also 
been met with in Devonshire by Miss Ellen Clayton, and Mr. R. H. Meade has captured it in 
Yorkshire. The sexes arrive at maturity in autumn, and are sometimes abundant in localities 
suited to their habits. If this spider be compared with Linypliia marginata it will immediately 
be seen how easy the transition is from the genus Linypliia to that of Neriene.

Length of the female, 3 th of an inch; length of the cephalo-thorax, hth, breadth, i' B th; 
breadth of the abdomen, ^th; length of an anterior leg, Rh; length of a leg of the third 
pair, Jth. 
The cephalo-thorax is convex, glossy, compressed before and rounded on the sides, with 
an indentation in the medial line ; the falces are robust, conical, vertical, and armed with teeth 
on the inner surface; the maxillae are enlarged at the extremity, and slightly inclined towards 
the lip, which is semicircular and prominent at the apex; the sternum is heart-shaped ; the 
legs are provided with erect spines, and the anterior and posterior pairs are equal in length; 
each tarsus is terminated by three claws; the two superior ones are curved and pectinated, 
and the inferior one is inflected near its base; the palpi have a curved claw at their extremity. 
These parts have a red-brown colour, the sternum, lip, maxillae, and margins of the cephalo- 
thorax being the darkest, and the eyes are seated on black spots. The abdomen is oviform, 
convex above, projecting over the base of the cephalo-thorax; it is thinly clothed with hairs, 
glossy, and of a brownish-black hue. 
The sexes are similar in colour, but the male is rather smaller than the female, and has 
some slender bristles, curved forwards, on the anterior part of the cephalo-thorax. The 
cubital and radial joints of its palpi are short; the former has a fine bristle at its extremity, in 
front, and the latter, which is the stronger, has a small protuberance on the outer side of the 
upper part fringed with long bristles; the digital joint is somewhat oval, with a large, 
obtuse process at its base, and a prominent lobe on its outer side ; it is convex and hairy 
externally, concave within, comprising the palpal organs, which are highly developed,
