REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 455 
the cepbalothorax; it is thinly clothed with hairs, and is of a blackish colour tinged with 
olive-green ; when in spirit of wine some paler spots and lines, both transverse, oblique, 
and longitudinal, are visible. : 
The adult female differed from the male only in wanting the hornlike projections on 
the forehead, in being slightly larger, and in the fore part of the cephalothorax being 
less convex. Sexual organs well developed and of a red-brown colour. Their external 
form is given in the accompanying drawing (Pl. 57. no. 39. fig. f). 
An adult male and female of this (the smallest Spider, I believe, yet known to science) 
were captured by myself among moss in a wood near Bloxworth, Dorset, at the end of 
March, 1868. Subsequently (in March 1866) another adult example of each sex was 
found, after many days' close search, in a similar situation and at no great distance from 
the spot where the former examples were obtained. It thus seems to be a rare as well as 
very remarkable little Spider; and the male is recognizable from all other species known 
to me by the two horn-like tufts of bristles between the eyes. 
WALCKENAÉRA PERMIXTA, n. sp. (Pl. 57. no. 40.) 
Male adult, length 45; of an inch; relative length of legs 4, 1, 2, 3. 
Cephalothorax very glossy, flattish at the hinder part, rising gradually to the ocular 
region, the hind slope of which is but very little more abrupt than the rest. Ocular 
region very prominent and elongated: its extremity is divided into two segments by 
a deep transverse cleft, the hinder segment being much the smallest; the apex of each 
segment is rounded off and furnished with short, bristly, pale-coloured hairs, directed 
towards, and partially meeting over, the cleft; there is a small indentation in the 
median line of the hinder part. Colour shining dark rich brown. 
Eyes eight, in four pairs, not very unequal in size—one pair on the summit of the 
hinder segment of the ocular region a little below the upper margin and rather towards 
the back, a pair just below each end of the cleft which divides the two segments, and 
the remaining pair in front of the foremost segment; all on black spots, those on which 
the side pairs are seated slightly tuberculate; the eyes of the hinder pair widest apart, 
those of the side pairs nearest together, those of the front pair rather close to each 
other, but not quite touching. 
Legs moderately long and strong, clothed with hairs and a very few fine erect bristly 
hairs, or very fine spines?; those of the first and fourth pairs are about equal in length, 
those of the third pair shortest. Colour red-brown. 
Palpi moderately long and strong; cubital joint long, subconical or clavate, and 
notched at its extremity ; radial joint short, but with a long stout elongation stretching 
from its extremity obliquely inwards over the base of the digital joint; from the end of 
this projection issue two or three short black reflex spines ; digital joint oval, comprising 
the palpal organs, which are prominent and complicated, with spiny processes, and 
closely encircled by a strong black spine issuing from the inner side and curving upwards 
round their extremity. The colour of these organs is red-brown; the digital and radial 
joints are rather paler and hairy; the remaining portions of the palpi are coloured like 
the legs.
