is pubescent, mixed with some larger stronger hairs; the underside is yellow-brown, 
suffused with blackish. 
An adult male of this fine spider, which I believe to be undescribed, was contained 
(along with the foregoing species) in a small collection of spiders kindly forwarded to 
me from Scotland by Mr. J. W. H. Traill; it was found on a mountain near Braemar. The 
double claw, or talon, at the extremity of the digital joint of the palpus, is a good 
specific character in this species, and, as far as I am aware, it is a singular instance; 
no other species that I know of possesses more than one terminal palpal claw.

An adult male, with two adult females of this fine species, have been kindly given me 
lately by Mr. Henry Rogers; they were found at Freshwater, Isle of Wight, during the 
past summer (1872), by Mrs. H. Rogers. The species was first described by myself, from 
females received from St. Helena, where they were captured in 1869 by Mr. Melliss, by 
whom males have also been since found there, and forwarded to me. "Those now received 
from the Isle of Wight are identical with the St.-Helena examples ; and its occurrence in 
England is exceedingly interesting. It cannot be mistaken for any other British species 
yet known, though in general eolours and markings it bears strong resemblance to 
S. (Menemerus) vigoratus (Koch). The male (hitherto undescribed) is like the female 
in colours and markings, but has also a longitudinal dusky blaek band along the centre 
of the fore half of the upperside of the abdomen; the legs also are longer in the male, 
the tibiæ of the first pair being considerably longer, stronger, darker-coloured, and 
more hairy. ; 
The palpi are short, the cubital and radial joints exceedingly so; the femoral as well 
as the cubital and radial joints are furnished with white hairs, those of the innerside of 
the radial being the longest, and closely grouped in a sort of tuft; the form of this joint 
is peculiar, being produced on the inner side, and has a sort of oblique direction inwards 
when compared with the cubital joint. The digital joint is large and almost as long as the 
three before-mentioned joints put together; it is furnished with numerous strong, bristly, 
black hairs, especially on the sides ; at the base, rather on the outer side, is a small conical 
tooth-like prominence pointing backwards; the palpal organs are simple, but prominent, 
and highly developed, situated far back, and forming a strong, somewhat globular lobe, 
whose hinder extremity is beneath the radial joint; the central abdominal band was also 
more or less visible in one of the English examples, as well as in some of those females 
which were received from St. Helena subsequently to that from which the species was 
described and figured. (Conf. * Spiders of St. Helena," Proc. Zool. Soc. 1869, p. 542.)
