LINYPHIlDiE. 
the colour of the branchial opercula is pale-yellow; a large, very prominent, curved process, 
of a dark red-brown hue, is connected with the sexual organs; it is abruptly contracted in the 
curvature, and is recurved at its extremity, which is enlarged and deeply notched. 
The male, which resembles the female in colour, has some longish black bristles, directed 
forwards, on the anterior part of the cephalo-thorax, which is prominent. The cubital and 
radial joints of its palpi are short; the latter is the stronger, and a long, slender bristle 
projects from the extremity of the former, in front; the digital joint is somewhat oval, but is 
gibbous on the outer margin, and has a large process at its base, which is curved outwards 
and notched at its extremity; it is convex and hairy externally, concave within, comprising 
the palpal organs; these organs are highly developed, complicated in structure, provided with 
several curved, corneous processes, and are of a red-brown colour. The convex sides of the 
digital joints are directed towards each other. 
On obtaining a copy of the first volume of the ‘ Museum Senckenbergianum, and com¬ 
paring the description of M. Wider’s Linyphia lonyidens with that of Linyphiu tardipes, it was 
immediately perceived that they are specifically the same. 
This spider is found in Denbighshire, Yorkshire, and Lancashire, under stones and 
detached pieces of rock, and in December 1848, an adult female was received from Mr. J. 
Hardy, who took it in Berwickshire. It pairs in August and September, and the female 
fabricates several cocoons of white silk of a fine but compact texture, which she attaches to 
the inferior surface of stones by a small web; they are flat on the side in contact with the 
stones, and convex, with a depressed margin, on the opposite side. The largest of these 
cocoons measures one-fourth of an inch in diameter, and contains about forty spherical eggs 
of a pale-yellow colour, not agglutinated together, but enveloped in delicately soft silk. The 
snare of this species consists of a small, compact, horizontal sheet of web constructed in 
cavities beneath stones, on the under side of which it takes its station in an inverted position. 
In the disposition and relative size of its eyes an approximation to the Theridia may be 
traced.
