and of a dark-brown colour, mottled with grayish-brown ; a broad band extends along the 
middle, whose anterior part has a grayish-brown, and its posterior part, which is narrower, a 
yellowish-white hue; a small, black spot occurs in the middle of the band, at the commence¬ 
ment of the basal slope, and the colour of the lateral margins is yellowish-white. The eyes 
are disposed on the anterior part of the cephalo-thorax in two transverse, curved rows, forming 
a crescent; the lateral eyes are seated on a tubercle, and are larger than the intermediate ones, 
those of the anterior row being the largest of the eight. The falces are short, cuneiform, and 
vertical; the maxillae are convex at the base, obliquely truncated at the extremity, on the 
outer side, and inclined towards the lip; and the sternum is heart-shaped. These parts have 
a yellow-brown hue, the falces being much the palest in the middle, brownish black on the 
' outer side and at the extremity, and the maxillae brown at the base. The lip is large, 
triangular, and of a dark-brown colour, that of the apex being yellowish-brown. The legs are 
provided with hairs and spines, two parallel rows of the latter occurring on the inferior sur¬ 
face of the tibiae and metatarsi of the first and second pairs, which are much longer and more 
robust than the third and fourth pairs; the first pair slightly surpasses the second in length, 
the third pair is the shortest, and each tarsus is terminated by two curved, pectinated claws; 
they are of a yellowish-brown hue, the first and second pairs being the brownest, with brown 
streaks, spots, and annuli. The palpi, which are short, resemble the legs in colour, and have 
a curved, pectinated claw at their extremity. The abdomen is rather broader at the posterior 
than at the anterior extremity, somewhat convex above, and projects over the base of the 
cephalo-thorax; it is thinly clothed with short hairs, and of a gray colour on the upper part, 
with a strongly dentated, grayish-black band extending along each side of the medial line; 
these bands, which meet at the spinners, and several of whose exterior angles are produced in 
oblique lines to the corrugated sides, comprise between them a broad space tinged with brown 
in its anterior region, where it is marked with five indented spots, forming an angle whose 
vertex is directed forwards; the anterior extremity of the sides has a grayish-black hue, 
passing into brown towards the spinners ; the colour of the under part is grayish-brown on 
the sides, and yellowish-brown in the middle, with an obscure, brownish line extending from 
each brown branchial operculum to the spinners, where the two meet; the sexual organs are 
well developed, and of a reddish-brown hue, with a broad, longitudinal, yellowish-brown 
septum in the middle. 
An adult female of this species was taken by Mr. James Hardy among heath on a moor 
near Penmanshiel by Cockburnspatb, Berwickshire, in September, 1858.
