Mr. Bracxwall's Descriptions of new Species of Spiders, 645 
upper part; another curved, corneous process, whose point is enveloped 
in a delicate membrane, extends from the upper part to the extremity of 
the fifth joint, and within its curvature a small, dentated spine occurs ; 
their colour is red-brown. Abdomen oviform, convex above, projecting 
over the base of the cephalo-thorax ; it is thinly covered with hairs, glossy, 
and brownish black. Plates of the spiracles pale yellow. 
Adult males of this species were taken in Febrnary 1837, under fragments 
of rock imbedded in earth in the woods about Llanrwst. 
31. Neriéne viaria. Mas brunneus; abdomine nigricante ; filatoriis pallide 
flavescenti-brunneis. 
Length of the male roth of an inch; length of cephalo-thorax +; breadth 
vz; breadth of abdomen yz; length of an anterior leg 0 length of a 
leg of the third pair +. 
Cephalo-thorax oval, moderately convex above, glossy, with slight furrows on 
the sides, and an indentation in the medial line of the posterior region. 
Mandibles powerful, conical, armed with teeth on the inner surface, rather 
divergent at the extremities, and inclined towards the sternum, which is 
broad and heart-shaped. Maxille inclined towards the lip, which is 
semicircular and prominent at the extremity. First and fourth pairs of 
legs the longest and equal in length, third pair the shortest. These parts 
are brown, the margins of the cephalo-thorax and the lip being the dark- 
. est, and the legs and maxille the palest. Intermediate eyes of the ante- 
rior row much the smallest of the eight. The palpi resemble the legs in 
colour; the third and fourth joints are short, the former, which is the 
stronger, having some long hairs projecting from its extremity, in front ; 
the latter is gibbous underneath, at the base; fifth joint somewhat oval, 
with a large lobe on the outer side; it is convex and hairy externally, 
concave within, comprising the palpal organs, which are highly developed, 
complicated in structure, very prominent, and of a pale reddish brown 
colour. Abdomen oviform, convex above, projecting over the base of the 
cephalo-thorax ; it is thinly covered with hairs, glossy, and of a dark 
brown hue, approaching to black. Plates of the spiracles and spinners 
pale yellowish brown.
