DYSDERIDiE. 
Maxillae very powerful, short, broad, gibbous near the base, somewhat enlarged and 
rounded at the extremity, and slightly inclined towards the lip. 
Lip large, triangular. 
Legs moderately long and robust; the anterior and posterior pairs, which are the longest, 
are equal in length, and the third pair is the shortest.

The legs are moderately robust, provided with hairs and a few spines, and are of a 
yellowish-brown colour, with the exception of the femora of the first and second pairs, which 
have a dark-brown hue ; each tarsus is terminated by two small, curved claws. The cephalo- 
thorax is oval, convex, of a red-brown colour, the margins being somewhat darker, and has 
several rows of white, iridescent, scale-like hairs on the sides, which converge towards an 
indentation in the medial line. The falces are subconical and without teeth on the inner 
surface ; and the sternum is heart-shaped. These parts, with the maxillae and lip, are of a 
red-brown colour. The humeral joint of the palpi has a dark-brown hue, that of the cubital 
joint being yellowish-brown, and the radial joint, which projects a small, pointed apophysis 
from its extremity, in front, has a reddish-brown tint; the digital joint is oval, convex and 
hairy externally, concave within, comprising the palpal organs ; they are highly developed, 
prominent, not very complicated in structure, and of a reddish-brown colour. The abdomen 
is oviform, convex above, projecting over the base of the cephalo-thorax; its colour is dark- 
brown mingled with yellowish-brown ; white, iridescent, scale-like hairs are distributed over 
its surface, and a spot composed of dense, white hairs occurs immediately above the spinners. 
An adult male of this very interesting spider was captured at Broadstairs, in Kent, in 
the month of September, and is in Mr. F. Walker’s cabinet. It is preserved in Canada 
balsam, and has suffered from compression, circumstances which render an investigation of 
its structure difficult. On a most careful inspection of it under the microscope, only six eyes 
could be perceived; but even should it ultimately be found to possess eight of those organs, it 
must still, bv its other essential characters, constitute a new genus.
