black hue, with an obscure series of angular lines of a yellowish-brown colour, whose vertices
are directed forwards, extending along the middle of the upper part; it is sparingly supplied
with hairs, convex above, and projects over the base of the cephalo-thorax; the sexual organs
have a dark-brown hue; a prominent process is connected with their anterior and another
with their posterior margin; the former, which is much the larger, is nearly semicircular,
concave within, and has a longitudinal septum in the middle ; the posterior one is somewhat
enlarged at its extremity, and directed obliquely backwards.
The sexes are similar in colour, but the figure of the male is slighter than that of the
female; there are some fine bristles, directed forwards, on the middle of the anterior part of
its cephalo-thorax, and the falces have a small protuberance in front, near the base. The
palpi are short, and of a bright, yellowish-red colour, with the exception of the digital joint,
which has a dark-brown h u e ; the radial is stronger than the cubital joint, and is rather
produced in front; the digital joint is somewhat oval, with a lobe on the outer side, near the
base ; it is convex and hairy externally, concave within, comprising the palpal organs, which
are highly developed, prominent, complex in ' structure, with two contiguous, curved spines
near their middle, a compressed, curved process at the base, on the outer side, a pointed one
on the inner side, and are of a red-brown colour.
This species varies greatly in colour; some individuals have the yellowish-brown, angular
lines extending along the middle of the upper part of the abdomen very distinctly marked;
others have the ground-colour of the abdomen yellow-brown, and the angular lines black;
and occasionally specimens may be found with the abdomen of a uniform black, or yellowish-
brown hue.
The original description of IAnyphia Claytonice was made from adult males received from
Miss Ellen Clayton, who took them near Garstang, in Lancashire. In 1852, Mr. R. H. Meade
captured adult females at Bradford, in Yorkshire, which were described as a distinct species,
under the name of IAnyphia anthracina; however, a careful examination of both sexes, found
in considerable numbers in the summer of 1860 by the Rev. O. P. Cambridge, at Bloxworth,
in Dorsetshire, has served to establish the fact that they are specifically identical.

Length of the female, 5th of an inch; length of the cephalo-thorax, ^th, breadth, 5,th ;
breadth of the abdomen, 35th ; length of an anterior leg, ^ths; length of a leg of the third
pair, ^ths.
The four intermediate eyes, describe a trapezoid whose anterior side is the shortest, and
those of each lateral pair are seated obliquely on a tubercle, and are almost contiguous; the
posterior eyes of the trapezoid are the largest, and the anterior ones much the smallest of
the eight. The cephalo-thorax is oval, convex, glossy, with an indentation in the medial
lin e ; the falces are powerful, conical, armed with a few teeth on the inner surface, slightly
divergent at the extremity, and inclined towards the sternum, which is heart-shaped; the
maxillae are straight, with the exterior angle, at the extremity, curvilinear; and the lip is
semicircular and prominent at the apex. These parts are of a brown-black colour, the
sternum, lip, and lateral margins of the cephalo-thorax being the darkest, and the falces
having a tinge of red. The legs are long, slender, provided with hairs and a few fine spines,
and have a light yellow-brown h u e ; the first pair is the longest, then the second, and the
third pair is the shortest; each tarsus is terminated by three claws ; the two superior ones
are curved and slightly pectinated, and the inferior one is inflected near its base. The palpi
have a dark-brown tint, with the exception of the humeral joint, which has a yellowish-
brown hue. The abdomen is oviform, glossy, sparingly clothed with short hairs, convex
above, projecting over the base of the cephalo-thorax; it is of a brown-black colour, with a
sharply dentated, pale yellow-brown band extending along the middle of its upper part, and a
rather obscure line of the same hue on each side of its anterior extremity ; the sexual organs
have a thin, longitudinal septum in the middle, a small process connected with their posterior
margin, which is directed backwards, and their colour, with that of the branchial opercula,
is yellowish-brown. The medial, dentated band, is much less perfectly defined in some
individuals than in others.
The form of the male is slighter than that of the female, and its colour is darker, the
dentated band in the medial line of the upper part of the abdomen being rather more obscure.
The cubital and radial joints of the palpi are short, and the latter, which is the stronger, is
somewhat produced at its extremity, on the inner side; the digital joint is of an irregular
oval figure, having a slender, curved process at its base, on the outer side, and a large lobe
near its extremity, on the inner side; it is convex and hairy externally, concave within,
comprising the palpal organs; these organs are very highly developed, prominent, complicated
in structure, with two strong, curved spines at their extremity, one of which describes a
circle and comprises within its circumvolution some light-coloured membrane and the recurved
point of the other spine; they are of a dark-brown hue tinged with red. The convex sides
o f the digital joints are directed towards each other.
Both sexes of this spider, in a state of maturity, were discovered by Mr. R. H. Meade,
in the summer of 1852, on the fronds of the male shield-fern, in Nab Wood, near Bingley,
in Yorkshire; and in the autumn of the same year, an adult female was transmitted to him
by Mr. F. Walker, who took it at Southgate.
