332 REY. 0. P. CAMBRIDGE ON [Apr. 20, 
The falces are tolerably long and strong, and somewhat divergent 
towards their extremity, near which on the inner margin are several 
very minute teeth. 
The maxilla, labium, and sternum are of ordinary form. 
The abdomen is short oval and pretty convex above; its colour is 
a pale dull luteous brown, having a mottled appearance ; and it is 
thinly clothed with rather coarse longish hairs. 
This species is nearly allied to Z. viva (p. 330) ; but, among other 
distinctions, the difference in the relative position of the eyes of the 
hinder row, as well as the structure of the palpal organs, and absence 
of the strong tooth in front of the falces, will readily distinguish it. 
Adult males were received from M. Simon, by whom they were 
found at Troyes in France. 
ERIGONE GROUVELLU, sp.n. (Plate XLIV. fig. 7.) 
Adult male, length 1 line. 
The cephalothoraz of this Spider is of ordinary form; the profile 
describes a tolerably uniform gentle curve, with a very slight depres- 
sion between the occiput and the thoracic junction, the caput not 
being elevated above the general level. The height of the clypeus is 
scarcely equal to half that of the facial space; the normal grooves 
and indentations are visible,-but not very strongly marked; and 
some portions, if not the whole, of the surface, are very finely rugu- 
lose or striated with minute wrinkle-like markings. The colour of 
the cephalothorax is a deep yellow-brown, tinged with black; and 
the caput has a very few hairs along its median line. 
The eyes are in the usual position, not very small, nor differing 
greatly in their relative size; the front row is rather the shortest ; 
and both rows curve away from each other, forming a pretty regular 
oval figure ; the eyes of the hinder row are very nearly equidistant 
from each other, the interval between the centrals being perhaps 
rather less than that which divides each from the lateral eye on its 
side ; those of the fore central pair are near together but not con- 
tiguous to each other, the interval between them being about half 
that which separates each from the fore lateral on its side; those of 
each lateral pair are placed slightly obliquely on a tubercle; the 
interval between each of the hind central eyes and the fore central 
nearest to it is distinctly greater than that which divides the eyes 
of the hind central pair, and a little greater than that which sepa- 
rates each of these from the hind lateral on its side. 
The legs are slender and of tolerable length; they are of a dull 
yellow colour, the femora being tinged with orange, and are fur- 
nished with hairs and a few slender spine-like bristles. 
The palpi are short, moderately strong, of a duller hue than the 
legs, and furnished with a few hairs: the cubital and radial joints 
are very short ; the former is bent and has a single strongish, tapering, 
prominent, slightly sinuous black bristle a little above its fore ex- 
tremity on the upperside; the radial joint is stronger than the 
cubital, with one or two slight prominent points at its fore extremity 
on the upperside; the digital joint, which is of a dark black-brown
