204 REV. O. P. CAMBRIDGE ON [ Mar. 16, 
longer than the radial, slightly clavate, and bent downwards ; the 
radial is very short, produced behind into a strong obtuse apophysis, 
and in front into a long, tapering, rather curved, pointed one, which 
fits rather closely upon the external surface of the digital joint and 
is directed outwards; the digital joint is of moderate size; and the 
palpal organs are neither very prominent nor complex; at their ex- 
tremity is a very slender filiform, sharp-pointed, circularly curved, 
closely-fitting spine. 
The falces are of moderate length ; but not very strong ; they are 
very nearly vertical, and armed on their inner edges towards the 
extremity with minute denticulations. 
The mawille and labium are of normal form. 
The sternum is of the ordinary heart-shape, and very convex and 
lossy. 
z The abdomen is oval, moderately convex above, of a jet-black 
colour, thinly clothed with hairs, and projects, but not very strongly, 
over the base of the cephalothorax. 
An adult male of this Spider, which is nearly allied to Hrigone 
antica (Wid.) and EL. flavida (Menge), was received from M. Simon, 
by whom it was found in Corsica. 
ERIGONE EBORODUNENSIS, sp. n. (Plate XXVIII. fig. 13.) 
Adult male, length barely 1 line. 
The cephalothorax, falces, maxillee, and labium of this Spider are 
yellow-brown, the legs and palpi dull yellow, the digital joints of the 
latter strongly tinged with brown, the sternum and abdomen dull 
brownish black. , 
The fore part of the cephalothorax is bluff and obtuse, the caput 
being slightly elevated, the summit rounded, the occipital slope 
tolerably abrupt; the ocular area slopes forwards, and its profile, 
with that of the clypeus (whose height equals not quite half that of 
the facial space), forms an almost evenly curved line; from a little 
above and behind each hind lateral eye a deep tapering indentation 
runs backward in a horizontally longitudinal line to the lower part 
of the occiput; the other, normal, indentations are fairly but not 
very strongly marked ; the ocular area has a few short hairs in a 
longitudinal central line; some of these are directed downwards, and 
some upwards. 
The eyes are in the usual four pairs and seated on black spots ; 
those of one pair, situated on the fore part of the summit of the caput, 
just at the beginning of its front slope, are separated by nearly two 
diameters ; the two lateral pairs are placed at a considerable distance 
below ; those of each of these pairs, respectively, are contiguous to 
each other and placed slightly obliquely, and with the eyes of the 
upper pair they form a quadrangular figure, three sides of which are 
about equal in length, while the fourth (7. e. the upper) side is con- 
siderably less ; the eyes of the fore central pair are the smallest of 
the eight, dark-coloured and obscure, contiguous to each other, and 
placed in a straight line with the two fore lateral eyes; except the 
fore central pair, the eyes are shining pearly white.
