joint of the palpi, which is shorter than the cubital, projects three apophyses from its extremity;
the smallest is situated underneath, the largest in front,' and the third, of intermediate size,
on the outer side ; the digital joint is oval, convey and hairy externally, concave within, comprising
the palpal organs, which are highly developed, complicated in structure, with a hold
protuberance near the middle, and a.short, fine, curved spine at the extremity; their colour is
dark reddish-brown. The abdomen is oviform, rather broader at the posterior than at the
anterior extremity, convex above, projecting over the base of the cepbalo-thorax; it is thinly
clothed with hairs, glossy, and of a brownish-black hue, that of the branchial opercula being
dull-yellow.
In March, 1837, males of this species, in a state of maturity, were found under stones in
woods about Llanrwst,

The cephalo-thorax is, oval, convex, glossy, with a slight indentation in the medial line;
the falces are conical, somewhat inclined towards the sternum, arid armed with a few teeth
on the inner surface; the maxillae are short, convex at the base, and inclined towards the
lip; the legs and palpi are*moderately long and provided with hairs; the first and fourth
pairs of legs are the longest, and equal in length, 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 abdomen is oviform, glossy, thinly clothed with
hairs, convex above, and projects over the base of the cephalo-thorax. These parts are of a
pale, dull, brownish-yellow colour; the anterior region of the cephalo-thorax, where the eyes
are situated, and its lateral margins being of a dark-brown hue, and the tibiae of the first and
second pairs of legs having a tinge of brown. The lip is semicircular and prominent at the
apex; and the sternum is broad, heart-shaped, convex, and glossy. These parts are of a
brown colour, the lip and margins of the sternum being .,tbe darkest. The eyes are disposed
on the anterior part of the cephalo-thorax in two transverse rows; the four intermediate ones
form a trqpezoid whose anterior side is the shortest, and those of each lateral pair are seated ‘
obliquely on a minute tubercle, and are contiguous; the two anterior eyes of the trapezoid
are the smallest of the eight. The sexual organs have a dark, reddish-brown hue, with a
pale-yellowish septum in the middle.
The male is smaller than the female, but it resembles her in colour. The anterior part of
its cephalo-thorax is elevated, obtuse, inclined backwards, very convex behind, and depressed
on the sides. The two posterior eyes are seated on the summit of the cephalic eminence, in
front 5 the other six are situated much lower, but considerably above the frontal margin, so
tfyat the four intermediate ones describe a long, narrow trapezoid. The palpi are short, and
the radial and digital joints have a brown hue ; the radial, which is much shorter than the
cubital joint, projects a small, pointed apophysis from its extremity, in front, and a smaller one
‘underneath; the digital joint is short, broad, convex and hairy externally, concavé within,
comprising the palpal organs, which are moderately developed, prominent, complicated in
structure, with a curved, black spine near their extremity, on the inner side, and are of a
reddish-brown colour.
Both sexes of this small Walckenaera were found by the Rev. O. P. Cambridge among
gorse at Hursley, near Winchester, and at Lyndhurst and at Bloxworth, in the summer of
1860.

The cephalo-thorax, which is of an elongated-oval form, is Cönvèx, glossy, with a
minute indentation in the medial line, and an erect, Conical prominence in front, surmounted
by a tuft of fine hairs; the falces are small, conical, armed with teeth on the inner sürfacè,
and inclined towards the sternum, which is broad and heart-shaped; the maxillae are enlarged
at the base, where the palpi are inserted, and greatly inclined towards the lip, which is semicircular
and prominent at the apex. These parts have a brownish-black hue, the falces and
maxillae being faintly tinged with red. The eyes are small; four are disposed in a transverse
row behind the base of the frontal prominence, and immediately before each lateral eye another
is situated; two more, seated near the front of the apex of the prominence, are the darkest
of the eight, and are distinguished with difficulty. The legs are moderately long and
provided with hairs; the anterior and posterior pairs are the longest, and equal in length, and
the third pair is the shortest; they are of a brown hue, tinged with red; each tarsus is
terminated by three claws; the two superior ones are curved and pectinated, and the inferior
one is inflected near its base. The palpi resemble the legs in colour, and the radial, which is
larger and darker than the cubital joint, is depressed, hairy, and tapers to an acute point,
curved outwards in front of the digital joint; the digital joint is somewhat oval, having a
prominent lobe on the outer side* near the base; it is convex and hairy externally, concave
within, comprising the palpal organs, which are highly developed, complex, with curved,
spine-like processes,-and are of a dark, red-brown colour. The abdomen is oviform, convex
