REV. O. P. CAMBRIDGE ON NEW AND RARE BRITISH SPIDERS. 545 
those of each lateral pair are placed a very little obliquely, seated on a slight tubercle, 
and the fore ones are the largest of the eight. 
The colour of the cephalothorax, falces, and sternum is a dark reddish brown; the 
legs, palpi, and maxille yellow tinged with orange; the abdomen is dull black tinged 
with olive, and (in spirit) shows some fine pale lines and spots; the spinners are so short 
as to be scarcely visible. 
The /egs are rather slender, but of moderate length, and furnished with coarsish hairs 
and a very few fine erect bristles. "Their relative length is 4, 1, 2, 3. 
The falces are of moderate length and strength; they are protuberant near their base 
in front, and divergent at their extremities, the divergence being more apparent than 
real, being caused by the oblique truncation of their inner extremities and the hollowing 
of the exterior line (when looked at from the front). 
The form of the genital aperture is characteristic (vide fig. 15 d). 
It is possible that this may be the female of some already described male, though 
Ithink it is not. The form of the genital opening, the profile of the cephalothorax, the 
position of the eyes, with the height of the clypeus and the form of the abdomen, are all 
strong characters in this spider; in fact, the most of these characters (all indeed except 
the abdomen) are the mainly reliable and distinguishing ones in females of this genus. 
A single example was received in October 1871 from the Cheviots, where it was found 
by Mr. James Hardy, and by him kindly forwarded to me among many others. 
"NERIENE MORULA, Sp. n. (Pl. XLVI. fig. 16.) 
Male adult, length 1 line. 
The cephalothorax of this spider is of a deep yellow-brown colour, the legs and palpi 
dull orange, and the abdomen blackish. The cephalothorax is of ordinary form, and the 
height of the clypeus equals half that of the facial space. 
The legs are moderately strong, not very long, and are furnished with hairs and a few 
erect strong bristles or very fine slender spines. 
The palpi are short ; the radial joint is stronger but about equal to the cubital in length, 
and has its fore extremity on the upperside produced into a tapering pointed apophysis, 
nearly equal to the joint in length, and is directed inwards; the digital joint is of 
moderate size; and the palpal organs are well developed and rather complex. 
The eyes are rather closely grouped, the front row nearly straight, the hinder one 
much curved; those of the hind central pair are further from each other than each is 
from the hind lateral on its side. Those of each lateral pair are contiguous to each 
other, and placed slightly obliquely. Each hind lateral eye is very near to the hind 
central on its side. Those of the fore central pair are the smallest of the eight, and con- 
tiguous to each other. The hind central eyes form with each fore central a very nearly 
equilateral triangle. 
The falces are rather long and not very strong.
