formed supernumerary tarsus connected with the base of the tarsal joint of the right posterior
leg, on its outer side ; and in the spring of 1851 another adult female was obtained which had
only six eyes; not the slightest rudiment of the lateral eyes of the anterior row was perceptible,
even with the aid of a powerful magnifier.
Mr. R. Templeton has taken this species in Ireland.

Considerable variety may be observed among, individuals of this species, some being
much lighter coloured than others. The intermediate eyes of the anterior row are rather
larger than the lateral ones. The cephalo-thorax is hairy, marked with furrows on the sides,
which converge towards the middle, and has a narrow indentation in the posterior region;
its colour is dark-brown, with yellowish-brown margins, and a band of the latter hue extending
along the middle, which is broadest at the anterior extremity. The falces are powerful, and
are armed with teeth on the inner surface; the lip is rather longer than broad ; and the
sternum is heart-shaped. These parts are of a dark-brown colour, with the exception of the
extremity of the lip, which has a red-brown hue. The maxillae are obliquely truncated at the
extremity, on the inner side, and are of a reddish-brown colour. The legs and palpi have a
reddish-brown tint, and are marked with brownish-black annuli. The abdomen is oviform,
hairy, convex above, projecting over the base of the cephalo-thorax ; it is of a dark-brown
colour, on the upper part, with three small tufts of yellowish-brown hairs at its anterior
extremity; a broad band of a pale, yellowish-brown colour, extends along the middle and
tapers to the spinners; the anterior part of the band comprises an oblong, brownish-black
mark, having an angular projection on each side, and its posterior extremity bifid; between
this mark and the spinners there is a series of black lines, forming very obtuse angles, whose
vertices and extremities are the most distinct; the sides are mottled with yellowish-brown,
and the under part is of a pale, yellowish-brown hue.
The male is smaller and slenderer than the female, and the colour of the margins of the
cephalo-thorax and of the broad band extending along its middle is gray. The legs have a
yellowish-gray hue, and are without annuli; but the under part of the femora, the tibiae, and
the base of the metatarsi of the anterior pair, are black, tinged with brown, the tibiae being
densely covered with long black hairs on the under side. The palpi are of a brownish-black
hue, with a tinge of red ; the cubital and radial joints are short, the latter being rather the
larger, and the digital joint is of an oblong Oval form, convex and hairy externally, and concave
within, at the base; this concavity comprises the palpal organs, which are moderately
developed, rather complicated in structure, with a minute, curved, prominent process on the
outer side, having immediately before it a small, semi-transparent membrane, and are of a
brownish-black hue, with parts of a pale, yellowish-brown colour intermixed. The band extending
along the middle of the abdomen, the oblong mark comprised in its anterior part, and
the series of obtusely angular lines occupying the space between that mark and the spinners,
are much paler than in the female; and the under part of the abdomen is of a yellowish-gray
colour.
This spider frequents commons and old pastures. The palpal organs of the male are
fully developed in autumn.

Length of the female, |ths of an inch length of the cephalo-thorax, Jth, brea’dth, Jth ;
breadth of the abdomen, jth; length of a posterior leg, ijigength of a leg of the third
pair, fths.
The cephalo-thorax is large, hairy, and marked with slight furrows on the sides, which
converge towards a narrow indentation in the medial lin e ; it is of a dark-brown colour, with'
a broad, yellowish-brown band extending along the middle, and an obscure one of the same
hue above each lateral margin. The falces are powerful, conical, and armed with a few teeth
on the inner surface; their colour is dark-brown, faintly tinged with red near the base, in front.
The maxillae have a reddish-brown hue. The colour of the lip is dark-brown, with the
exception of the extremity, which has a reddish-brown tint. The sternum is heart-shaped,
glossy, and has a brownish-black hue. The legs are robust, and of a reddish-brown hue,
with brownish-black spots and streaks on the* thighs ; and the colour of the palpi resembles
that of the legs. The abdomen is oviform, hairy, convex above, projecting over the base of
the cephalo-thorax; a broad, yellowish-brown band, which tapers to the spinners, occupies
the middle of the upper part; anteriorly it comprises an oblong oval mark of a deeper shade,
whose margins are blackish; this mark extends nearly half the length of the abdomen, and
terminates in a point; the yellowish-brown band has a black border, broken into spots
posteriorly, which spots form, with smaller confluent ones of the same hue, oblique lines
extending down the sides, the ground-colour of which is yellowish-brown; the under part also
has a yellowish-brown hue, and is marked with three obscure, longitudinal, dark-brown bands ;
the colour of the branchial opercula is brown, the inner margin having a tinge of r ed ; and
the sexual organs, which have a dark, reddish-brown hue, are bisected longitudinally by a
septum. Some individuals have the posterior half of the yellowish-brown abdominal band
