quadrangle, and a series of abbreviated, pale» transverse, irregular lines extending from
the base to the spinners, to which numerous pale lines approach from the sides and from
before, those on the anterior part of the sides being white, nearly straight, and running
almost directly backwards ; the under part is of a castaneous-brown colour, with four
longitudinal rows of pale dots extending from the base to the spinners, and slightly
converging.
This spider was caught running among grass at Cranmore, in Ireland, and is very rare.

The eyes are disposed in two transverse rows on the anterior part of the cephalo-thorax ;
the posterior row is the longer, and the anterior row is situated very near to the frontal
margin ; the,intermediate eyes of both rows form a trapezoid whose shortest side is before,
those of the anterior row being the largest of the eight. The cephalo-thorax is somewhat
oval, convex, slightly compressed before, broadly rounded in front, and thinly covered
with short hairs; the falces are powerful, conicalf rather prominent, and armed with a
few teeth on the inner surface ; the maxillæ are long, straight, gibbous near the base,
enlarged where the palpi are inserted, and at the extremity, which is obliquely truncated and
fringed with hairs on the inner side ; the lip is moderately long, and truncated at the apex ;
the sternum is oval, with small eminences on the sides, opposite to the legs; the legs
are robust, and are provided with hairs and sessile spines ; the fourth pair is the longest,
then the second, and the third pair is the shortest ; each tarsus is terminated by two curved,
pectinated claws, below which there is a small scopula. These parts, with the palpi, are of a
reddish-brown colour, the anterior part of the cephalo-thorax, the falces, maxillæ, lijb, and
margins of the sternum being much the darkest, and the legs and palpi the palest. The
abdomen is of an oblong-oviform figure, densely covered with hairs, and projects a little
over the base of the cephalo-thorax ; the upper part is of a dark-brown colour ; a broad band
of yellowish-brown extends along the middle, and co'mprises a very dark-brown band, which
tapers towards the spinners ; the 'posterior half of the latter band is crossed by lines of
the same hue, forming obtuse angles whose vertices are directed forwards ; the sides are of a
dark-brown hue, and the under part has a yellowish-brown tint ; the spinners are prominent,
«nd of a pale, reddish-brown colour; and that of the branchial opercula is yellowish-
white.
The sexes differ in size and in the relative length of their legs, the male, which is
smaller than the female, having the second pair of legs longer than the fourth pair. The
radial joint of the palpi is slenderer than the cubital, and has a small, crescent-shaped
apophysis at its extremity, on the outer side, the anterior limb of which is much the darker
coloured; the digital joint is oval, convex and hairy externally, ooncave within, comprising
the palpal organs; these organs are highly developed and very prominent, extending upwards
to the articulation of the radial with the cubital joint; they are simple in external structure,
have a minute, pointed spine at their extremity, and are of a pale, red-brown colour.
In the wooded parts of Denbighshire this spider is found among ivy and lichens
growing on trees. It spins a large sac of white silk on the under side of leaves or behind
exfoliating bark, in which the female constructs a cocoon of a lenticular form in the month of
July; it is composed of white silk, of a very fine texture, is three tenths of an inch in
diameter, and contains between thirty and forty spherical eggs of a pale-yellow colour,
not agglutinated together.

The eyes are arranged on the anterior part of the cephalo-thorax in two transverse
parallel rows; the anterior row is the shorter, and is situated immediately above the frontal
margin; the intermediate eyes of both rows form a trapezoid whose shortest side is before,
those of the anterior row being the largest of the eight. The cephalo-thorax is convex
glossy^ rounded on the sides, broadly truncated in front, and sparingly covered with short
hairs; its colour is dark-brown, the anterior part and lateral margins being much the darkest..
The falces are powerful, conical, convex at the base, in front, rather prominent, armed
with a few teeth on the inner surface, and of a very dark-brown colour, approaching to
black. The lip is somewhat oval, truncated at the apex, and resembles the falces in colour.
The maxillm are long, straight, enlarged where the palpi are inserted, and at the extremity,
which is rounded. The sternum is oval, glossy, with small eminences on the sides, opposite
to the le g s ; its colour, and that of the maxillae, is dark, reddish-brown. The legs are short,
and of a pale, dull-yellowish hue; the fourth pair is the longest, then the second, and
the third pair is rather the shortest; eaelj tarsus is terminated by two curved, pectinated
claws, and below them there is a small scopula, The palpi, which are short, have a curved
