218 REV. 0. P. CAMBRIDGE ON (Mar. 16, 
like hook, not easily seen, at its extreme point), and much longer 
than the other; from the outer side of the radial joint there issues 
a short, slightly curved, tapering, sharp-pointed, blackish spine ; the 
whole length of the radial joint and its apophysis is less than that 
of the cubital: the digital joint is rather large, somewhat roundly 
truncate at its hinder extremity: the palpal organs are very pro- 
minent, highly developed and complex ; at their base, near the outer 
side, is a circularly curved, reddish spiny process ; about the middle 
of their outer side is a large, somewhat globular, whitish corneous 
lobe, in front of which is a circularly curved, black, flattish spine, 
its prominent extremity obtuse and bifid; and within its curvature is 
a prominent, obtuse, corneous process. 
The falces are rather weak, but of moderate length, and similar 
to the cephalothorax in colour. 
The mavwille are strong, of normal form, and, with the labium, 
similar in colour to the falees. 
The sternum is of a reddish orange-yellow colour, and its surface 
is covered with punctures similar to those on the thorax. 
The abdomen is large, oval, and projects considerably over the 
base of the cephalothorax ; it is moderately convex above, and clothed 
with short bristly hairs ; the sides and hinder part are longitudinally 
rugulose, blackish, with yellowish-brown between the wrinkles; and 
the upperside is covered with a coriaceous epidermis of a deep 
blackish bistre-brown colour, thickly set with punctured spots. 
The female is rather larger than the male, but resembles it in 
colours and general characters, the thorax and sternum being 
similarly punctured, and the upperside of the abdomen also covered 
with a coriaceous punctured epidermis; the occiput is roundly 
gibbous; and the eyes (as in all other females of this group) more 
closely massed together; those of the hind central pair bemg but 
one diameter’s distance from each other; the form of the genital 
aperture is, as usual, characteristic, being of a somewhat triangular 
shape. 
An adult example of each sex was received, in January 1872, from 
M., Simon, by whom they were found in Corsica, 
ERIGONE PROTUBERANS, sp. n. (Plate XXIX. fig. 24.) 
Adult male, length nearly 13 line. 
This Spider is allied to Z, latifrons (Camb.) ; but its caput is less 
distinctly divided into two segments by a longitudinal indentation 
over the summit of its elevated portion. The clypeus, whose height 
is half that of the facial space, is furnished with some hairs just 
below the fore central pair of eyes; the space clothed with hairs is 
defined by being rather darker than the rest; the palpal organs 
are complex, and, besides several irregular corneous processes, a 
sharp-pointed, strongish, filiform spine issues from their extremity 
on the outer side, and, curving upwards and backwards, bas its sharp 
point near their centre, more than halfway towards the hinder 
extremity of the digital joint and below the hinder part of the 
radial joint ; this joint is strong though shorter than the cubital, and.
