REV. O. P. CAMBRIDGE ON NEW AND RARE BRITISH SPIDERS. 525 
middle row are largest of the eight, and form a line shorter than that formed by the two 
eyes of the hinder row. These four eyes occupy the whole width of the fore part of the 
caput, and form a large quadrilateral figure, whose hinder side is the longest, and the 
fore side rather the shortest; the line formed by the four smaller eyes of the front or 
- lower row is as long as that formed by the middle row; its lateral eyes are smaller than 
those of those of the central pair; and these last are further from each other than each is 
from the lateral on its side. This row equally divides the space between the middle row 
and the lower margin of the clypeus; i.e. the height of the clypeus equals the space 
between the foremost and middle rows of eyes. 
The legs are long and moderately strong, their relative length 4, 3, 1, 2; those of the 
fourth pair are considerably the largest ; they are furnished with hairs, bristles, and spines, 
the latter being most numerous, longest, and strongest on the legs of the third and fourth 
pairs. They are of a yellow-brown colour, banded, striped, and marked with deeper brown. 
The legs in the female are more regularly and distinctly annulated than in the male; 
the paler portions are (in both sexes) clothed with greyish-white pubescence. 
The palpi are rather long and strong; they are similar in colour and markings to the 
legs; the greater portion of the digital joint, however, is black ; the radial joint is longer 
than the cubital, and (as well as the digital) is furnished pretty thickly with black hairs ; 
the cubital joint is bent, and a single, straight, tapering, but not very sharp-pointed 
spine issues forwards from its fore extremity on the upperside; the digital joint is 
long and strong; the palpal organs, situated near the base of the joint, are prominent ; 
they consist of. a somewhat horseshoe-shaped lobe, directed backwards; and from its flat 
upper surface issue two strong, prominent, spiny, divergent processes, the inner one 
of which is curved, and double the length and strength of the outer one. These processes 
are united at their base, and, from one point of view, form a kind of crescent-shaped 
process, with one horn stronger than the other. 
The falces are not very long nor strong; when looked at in profile, the maxillee pro- 
ject a little beyond them ; they are reddish-yellow brown in colour, clouded and marked 
with black. 
The sternum is oval, glossy, and black. 
The abdomen is thickly clothed with hairs, and of a dull sooty black colour above; 
there is but little trace of pattern or markings; the normal elongate stripe or band on 
the fore half is faintly visible, of a yellowish red-brown colour, bordered by a blacker line, 
and (apparently) sharp-pointed at its hinder extremity; on the hinder portion are some 
rather obscure spots, formed by pale whitish hairs, arranged longitudinally in a row on 
either side ; and between these rows are some equally faint and similarly formed transverse 
eurved lines; the underside is of à vinous brown colour, clothed thinly with a whitish 
pubescence. The plates of the spiracles are black ; and the spinners, which are very short, 
are also black. 
An adult male and two females of this very distinct species were received in the spring 
of 1872 from Braemar, in Scotland, where they were found on the mountains, and kindly 
forwarded to me by Mr. J. W. H. Traill, of the University of Old Aberdeen, after whom 
I have great pleasure in naming it.
