330 REY. 0. P. CAMBRIDGE ON [Apr. 20, 
sides and furnished (at the parts furthest from the fangs) with 
two or three minute teeth. 
The abdomen is of a blackish yellow-brown colour. 
A single example of the adult male was received, in April 1573, 
from M. Eugéne Simon, by whom it was found near Paris. 
ERIGONE Viva, sp. n. (Plate XLIV. fig. 5.) 
Adult male, length 2 of a line=12 millim. 
The cephalothoraz of this Spider is of a brownish yellow colour, 
and presents nothing remarkable in its form; the profile line is 
slightly but pretty uniformly curved, its highest point being at the 
occiput ; the ocular region, as well as the median line from it back- 
wards, is furnished with a very few prominent hairs. The height 
of the clypeus equals half that of the facial space, and projects a 
very little forwards at its lower margin. 
The eyes are rather large, nearly equal in size, and seated on 
black spots, and, except those of the fore central pair, which are 
dark-coloured, of a bright pearly white lustre; the front row is (as 
is usually the case) the shortest, and (looked at from above and 
behind) the two rows appear equally curved from each other, forming 
a regular transverse oval figure; those of the hinder row are equi- 
distant from each other, being separated by as nearly as possible an 
eye’s diameter, those of the fore central pair (which are larger than 
usual, being but little smaller than the rest) are contiguous to each 
other, and each is separated by only a very slight interval from the 
fore lateral eye nearest to it; those of each lateral pair are seated 
obliquely on a tubercle and are contiguous to each other; thus the 
eyes of the lateral and fore central pairs form an almost continuous, 
semicircularly curved line. Each hind central eye is separated from 
the fore central nearest to it by an interval equal to that which 
divides those of the hinder row. 
The legs are moderate in length and strength, their relative 
length being distinctly 1, 4, 2, 3; they are of rather a paler colour 
than the cephalothorax, and are furnished with hairs and slender 
prominent and erect bristles of various lengths and strength. 
The palpi are similar in colour to the legs, slender and short ; 
the cubital joint is short and bent downwards ; the radial is still 
shorter, but has its fore extremity prominently produced into a 
rather long, strong, tapering apophysis, with a slightly hooked point 
when looked at in profile; about the middle of the outer side of this 
apophysis is a prominent somewhat tooth-like projection, and from 
the inner side of the joint projects another small pointed and 
slightly curved apophysis: the palpal organs are well developed, 
but not very complex, and directed outwards; at their base is a large 
red-brown and rather irregularly shaped corneous process, and at 
their extremity are several prominent black corneous points of dif- 
ferent sizes. 
The falces are similar in colour to the cephalothorax, tolerably 
long and strong, and nearly vertical; each has a strong curved but 
net very sharp tooth in front on its inner side towards the ex-
