SALTICIDiE. 
extremities nearly meet, and an obscure one on each lateral margin being whitish. The 
falces are vertical, and, with the maxillae, lip, and sternum, are of a very dark-brown hue. The 
legs are of a yellow colour, marked with longitudinal black streaks, particularly on the anterior 
side; the fourth pair is the longest, then the third, and the second pair is the shortest; each 
tarsus is terminated by two curved, pectinated claws. The hue of the palpi is pale-yellow. 
The abdomen is oviform, pointed at its posterior extremity, and projects over the base of the 
cephalo-thorax; above it is of a dark-green colour, with a curved, white line in front, which 
extends along the sides more than half of its length, and two irregular, parallel spots of the 
same hue on each side of the medial line; the under part has a brownish-black colour, and is 
thinly covered with whitish hairs. The white marks on the cephalo-thorax and abdomen, 
and the black streaks on the legs, are not constant, but are liable to vary in different 
individuals. 
The male bears a strong resemblance to the female, but it is smaller and darker coloui ed, 
the relative length of its legs also is different, the first pair being longer than the third , and 
the maxillte have a strong, bifid protuberance on the outer side, near the extremity. The 
palpi have a brownish-black colour, with some white hairs in front, which form a longitudinal 
line; the humeral joint is strong, and has a very large bifid protuberance on the under side, 
one division of which is longer and more pointed than the other; the cubital and radial joints 
are short; the former is mucli the larger, and the latter projects two long, pointed apophyses 
from its extremity, one on the outer side, and the other, which is curved, on the under side, 
the digital joint is of an oblong-oval form, convex, and hairy externally, concave within, com¬ 
prising the palpal organs; they are highly developed, prominent at the base, particularly on 
the inner side, not complicated in structure, with a curved, pointed, corneous spine at the 
extremity, and are of a brownish-black colour. 
There are several varieties of this spider, some of which have been described by arach- 
nologists as distinct species. Crevices among accumulated fragments of rock, occurring in 
woods in the mountainous parts of Denbighshire and Caernarvonshire, are frequently selected 
for its abode, and afford it great facilities of escaping from danger. In June the female 
encloses herself in a cell of white silk, of a compact texture, on the exterior surface of which 
particles of soil, withered moss, and other materials are sometimes sparingly distributed; she 
usually attaches it to the under side of stones or dead leaves, depositing in it from twenty to 
thirty spherical eggs, of a pale-yellow colour, connected by fine, silken lines.
