194 REV. 0. P. CAMBRIDGE ON [ Mar. 16, 
produced, of a somewhat truncate form at its upper extremity, not 
very dissimilar to that of Hrigone humilis (Bl.) ; looked at in profile 
the occiput is a little roundly convex, with a hollow between its highest 
part and the thoracic junction. From the summit of the occipital 
convexity the caput slopes gradually to the fore central eyes, spreading 
out laterally on both sides into a strong tuberculiform elevation ; at 
the summit of these elevations are the lateral pairs of eyes, from be- 
hind each of which a narrow indentation runs backwards. ‘The whole 
of this fore slope of the caput (including the four pairs of eyes) is 
clothed pretty thickly with longish and, for the greater part, bent 
hairs, mostly diverging from the central longitudinal line and directed 
backwards; these hairs are very characteristic and give the Spider 
a very peculiar appearance. 
The eyes are small, seated in four rather widely separated pairs on 
black spots, and form a rather narrow transverse area, whose width 
is no more than half its length; the lateral pairs, seated (as before 
mentioned) on two strong tuberculiform elevations, are nearly in a 
straight line with those of the hind central pair; those of this latter 
pair are rather smaller than those of the fore central pair, and are 
separated by an eye’s diameter ; these two pairs form an oblong rect- 
angular figure, whose length is about double its breadth ; and the in- 
terval between each eye of the hind central pair and the hind lateral 
eye nearest to it is equal to that between each of the former and the 
opposite fore central eye. 
The legs are slender and moderately long, their relative length 
being apparently 4, 1, 2,3; they are furnished with hairs and a 
slender spine-like bristle on the upperside of each of the femoral and 
tibial joints. 
The palpi are short and furnished sparingly with hairs ; the cubi- 
tal joint is bent and rather longer, but less strong than the radial ; 
this latter has its fore extremity produced into a long double twisted 
apophysis, its extreme point being rather obtuse and directed out- 
wards; about halfway along the outer side of this apophysis is a rather 
small but prominent, pointed, dark-coloured spine, not far in front of 
which is another small pale prominence. This part of the radial joint 
is not easy to be made out clearly ; the digital joint is of tolerable 
size ; the palpal organs are highly developed and rather prominent, 
with one or two filiform black spines connected with them. 
The falces are small and directed backwards. 
The mawille, labium, and sternum are of normal form. 
The abdomen is of ordinary form and projects well over the base 
of the cephalothorax ; it is of a dull blackish colour, suffused with 
yellowish on the fore part of the upperside, and its hinder portion 
marked with a series of 5 or 6 transverse curved yellowish lines, 
formed by tolerably distinct folds in the epidermis ; the spinners are 
short, small, and of a pale yellow colour, and the spiracular plates are 
inclosed in a large, somewhat quadrangular, yellow area. 
An adult male of this very distinct species was received from M. 
Eugéne Simon, by whom it was found in Corsica.
