legs in colour, and have a curved, pectinated claw at their extremity. The eyes are arranged 
on the anterior part of the cephalo-thorax in the form of a crescent, those constituting its 
cusps, which are seated on small tubercles, being the largest. 
In summer, when the sun shines brightjy, this species may be seen on rails and gates in 
the neighbourhood of Llanrwst. Early in June the female constructs a lenticular cocoon of 
white silk, of a slight texture, measuring one third of an inch in diameter, in which she 
deposits about sixty-four spherical eggs of a pale-yellow colour, not agglutinated together.

The abdomen is oviform, hairy, convex above, and projects a little over the base of the 
cephalo-thorax; the upper part is of a pale, yellowish-brown colour, mottled with reddish- 
brown, an obscure, oblong-oval band of the latter hue extending from the anterior extremity 
along the middle, nearly half of its length; it is encircled by an irregular band of a dark, 
reddish-brown colour, from which some imperfectly defined streaks pass obliquely upwards, 
particularly in the posterior region; the sides and under part are of a dull, yellowish-white 
hue, minutely spotted with reddish-brown, three red-brown bands extending along the middle 
of the latter and meeting in a point near the spinners; the sexual organs are of a very dark, 
reddish-brown colour; and the branchial opercula have a yellowish-brown hue. The cephalo- 
thorax is short, broad, convex, hairv, slightly compressed before, and rounded on the sides; 
it is of a yellowish-brown colour, with a broad, longitudinal, dark-brown band on each side, 
and narrow, pale, yellowish-white margins. The falces are conical, vertical, and armed with 
one or two very small teeth on the inner surface; the maxillae are enlarged where the palpi 
are inserted, and gibbous at the base; and the lip is triangular and rounded at the apex. 
These parts are of a yellowish-brown colour, the base of the lip being dark-brown. The 
sternum is heart-shaped, thinly covered with whitish hairs, and of a yellowish-brown hue, 
freckled with minute, blackish spots, which are densest on the sides. The legs are long, pro¬ 
vided with hairs and sessile spines, and are of a pale, yellowish-brown colour, interspersed 
with minute, blackish spots, which are scarcely perceptible without the aid of a magnifier; the 
second pair is the longest, then the first, and the third pair is slightly longer than the fourth; 
each tarsus is terminated by two curved, deeply pectinated claws, and below them there is a 
small scopula. The palpi resemble the legs in colour, and have a curved, pectinated claw at 
their extremity. The eyes are disposed on the anterior part of the cephalo-thorax in the
