REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 429 
Legs moderately long and strong. Relative length 4, 1, 2, 3, furnished with hairs and 
a few fine longish black spines. Colour pale yellow with a greenish tinge, broadly and 
distinctly banded (except the tarsi) with brownish-black. 
Falces long, strong, vertical, slightly divergent at the extremities, and a little pro- 
minent near their base in front. Similar in colour to the cephalothorax. 
Maaille strong, straight, parallel, and rounded at the extremities; rather paler in 
colour than the falces, and yellowish at the extremities. 
Labium short, semicircular, similar in colour to the cephalothorax. 
Sternum heart-shaped, and of a deep blackish-brown colour. 
Abdomen oval, very convex above, especially in front, and projects over the base of the 
cephalothorax ; it is of a dull greenish yellow-white, clothed sparingly with dark hairs; a 
broadish longitudinal black band runs backwards to the spinners from near the fore extre- 
mity, and contains two somewhat triangular whitish markings forwards, each divided longi- 
tudinally by a black line ; in continuance of the same longitudinal line towards the spin- 
ners are several more or less angular whitish lines, the angles directed forward; the 
sides are irregularly marked with blackish, and the underside is completely black. 
The sexual aperture is furnished with a strong prominent epigyne, furnished on the 
exterior side with coarse longish hairs; its extremity is of a dark red-brown colour; and 
inside it has a short curved process or ovipositor. 
A. single adult female of this species (which appears to me to be undescribed) was 
contained in a collection of Spiders made by Mr. William Farren, of Cambridge, in Wicken 
Fen, near that town, in February 1869. 
LINYPHIA EXPERTA, n.sp. (PL 55. no. 23.) 
Male adult, length + of an inch (or 14 line). 
Cephalothorax broad, oval, slightly compressed laterally in front, where it is somewhat 
roundly truncated; the sides of the thoracic region are a little depressed and sloping 
slightly forward at the eyes; caput rather rounded; the normal indentations are well 
marked, especially that on the hinder slope, which is gradual; margins black; clypeus 
perpendicular, its height is greater than the space from the front to the hind central 
pairs of eyes, inclusive of the eyes themselves, and about equal to the space between the 
fore lateral eyes; the surface of the cephalothorax is glossy, of a yellow-brown colour, 
and has a very few vertical dark hairs upon the caput. 
Eyes on slightly tuberculate black spots, in four pairs, or two transverse rows; those 
of the lower row are in a straight line, and the hinder row is slightly curved ; those of the 
fore central pair are the smallest of the eight and almost touch each other; each is distant 
from the lateral one of the same row nearest to it by rather more than its own diameter ; 
the same distance separates each from the hind central eye opposite to it; those of 
the hind row are equidistant from each other, the space between them being equal 
to that between each corresponding fore and hind central eye; those of the lateral 
pairs are placed obliquely and very nearly touch each other; these last are of a 
pearly-white colour; the hind centrals are tinged with bluish grey, the fore centrals
