538 REV. O. P. CAMBRIDGE ON NEW AND RARE .BRITISH. SPIDERS. 
row are rather nearer to each other than each is to the hind lateral on its side, but further 
from each other than each is from the fore lateral eye opposite to it; the eyes of each lateral 
pair are contiguous, and seated on a tubercle, the fore ones of these pairs being the largest 
of the eight. The interval between each fore central and the fore lateral eye on its side 
scarcely exceeds the diameter of one of the former. 
The height of the clypeus (which is prominent) is equal to two thirds of that of the 
facial space. | 
The legs are moderately long, and rather strong; their relative length is 4, 1, 2, 3; 
and they are furnished with hairs, fine bristles, and a few longish slender spines. 
The maxille are strong, rather long, and straight, but inclined towards the labium, 
which is broader than high, somewhat quadrate, rather roundish at the apex, and sharply 
impressed in a transverse direction across the middle. 
This spider is nearly allied to Z. pallida, Cambr., but may be distinguished by its 
much larger size and brighter colouring ; from L. reticulata (post, p. 540) it may be distin- 
guished by the markings on the abdomen as wellas by the greater height of the 
clypeus, and notably by the different form of the epigyne. 
A single example was forwarded to me in the spring of 1872 by Mr. James Hardy, by 
whom it had lately been found near Berwick-upon-Tweed. 
LINYPHIA PRUDENS, sp. n. (Pl. XLVI. fig. 9.) 
Male adult, length 12 line. 
This spider is similar in size, form, and general structure, to L. arcana (post, p. 539); 
it is, however, of a paler and duller hue; the ocular area is broader in proportion to its 
length ; the spines on the legs are stronger, and the palpal organs are easily distinguished 
by their different structure. 
The eges of the fore central pair are very small, contiguous to each other, and placed 
above the straight line formed by the fore laterals ; these are the largest of the eight, and 
larger than the corresponding eyes in L. arcana. 
The height of the c/ypeus exceeds half that of the facial space. 
The radial joints of the palpi are stronger, but of equal length with the cubital joints ; 
a tolerably long, strong, nearly straight, tapering, black bristle issues from near the 
upper fore margin both of the radial and cubital joints; the digital joint is not large, 
and it has an angular prominence near its base towards the outer side. 
The palpal organs are well developed, but not very complex; their leading and most 
distinctive character is furnished by a largish, somewhat crescent-shaped, corneous process 
at their base on the outer side the strongest part of the crescent is enlarged on its 
upper margin into a somewhat blunt angular form, so that when looked at from the front 
it appears of a blunt-angled triangular shape. "The oblique vandyke pattern on the sides 
of the abdomen in L. arcana is not visible in the present species; but a series of pale 
angular lines may be seen on the hinder half of the upperside of the abdomen. 
The relative length of the legs (which are moderately long and strong) is 4, 1, 2, 3.
