not agglutinated together. The cocoon is connected with her spinners by 
short lines of silk, and the young, when they quit it, mount on the body 
of the mother. I have seen this spider, which frequents woods, pastures, 
and commons, and is nearly allied to Lycosa vorax, on the sea-shore, 
just above high water-mark, and on the summits of Broad Crag, Helvel- 
lyn, Snowdon, and Carnedd Llewelyn, the highest mountains in England 
and Wales. 
4, Lycosa obscura. Saturaté brunnea ; cephalo-thorace medio lateribusque 
mandibulis maxillis pedibus palpisque obscurè rufescentibus ; abdo- 
mine obscurè rufescenti-branneo maculato, anticè fasciculis 3 minutis 
pilorum flavescentium ; pedum pari 4to longissimo, reliquis subæqua- 
libus. 
Length of the female 3th of an inch; length of cephalo-thorax 35; breadth Ar; 
breadth of abdomen Pr; length of a posterior leg 3y; length of a leg of 
the third pair 1. 
Anterior part of the cephalo-thorax compressed ; sides depressed, marked with 
slight furrows diverging from the upper part to the margins; in the me- 
dial line of the posterior region there is a narrow indentation. Mandi- 
bles powerful, conical, armed with a few teeth on the inner surface, 
inclined towards the sternum, which is heart-shaped and thinly covered 
with whitish hairs. Maxille straight, enlarged and rounded at the ex- 
tremity. Lip nearly quadrate, rather broader at the base than the 
extremity. These parts are very dark brown, the middle and sides of 
the cephalo-thorax, the maxillae and mandibles, having a faint tinge of 
red. Four eyes, much smaller than the rest, form a transverse row in 
front; the other four, situated on the sides and anterior part of the 
cephalo-thorax, describe a quadrilateral, the anterior eyes of which are 
the largest of the eight. Legs and palpi dark brown, with a tinge of 
red. Fourth pair of legs the longest; the other three pairs equal in 
length, or very nearly so; the third pair extends further, and appears to 
be longer than the first and second pairs in consequence of being articu- 
lated to the broadest part of the cephalo-thorax. Each tarsus is ter-
