and labium is yellow-brown, the sternum yellowish, and the 

 abdomen pale dull luteous. 



The cephalothorax is of an oblong form, slightly rounded at 

 each end, the hinder part being rather broader than the fore 

 part. The normal indentations are indistinct, and the lateral 

 constriction of the caput very slight. The height of the 

 clypeus equals, or is perhaps rather less than, half that of the 

 facial space. 



The eyes are small, in two curved rows, forming a tolerably 

 compact transverse oval figure. The posterior row is the 

 longest and most curved, and its eyes are equally separated 

 from each other by about an eye's diameter ; those of the 

 lateral pairs are rather tlie largest. The fore central pair are 

 very minute and, with the hind centrals, form a trapezoid, 

 whose length is a little greater than its breadth at the hinder 

 part, and the anterior side is much the narrowest. 



The legs are short and slender, 4, 1, 2, 3, the difference be- 

 tween those of the first and fourth pairs being very slight. 



The/«/ces are of moderate size and strength, straight and 

 vertical. 



The maxilke are short, strong, straight, and obliquely trun- 

 cated at their extremity on the outer side. 



The labium is short and semicircular. 



The abdomen is oval, bluff at the hinder extremity, consi- 

 derably convex on the upperside, and projects a good deal 

 over the base of the cephalothorax. The genital aperture is of 

 characteristic structure, and is comprised in a rather large 

 dark yellow-brown and blackish horseshoe-shaped area, form- 

 ing a very conspicuous object in contrast to the pale colour of 

 the abdomen. 



Four examples of this little spider were found among moss 

 near Bloxworth on the 29th of April, 1881. 



It seems to be allied to W. ingrata, Cambr,, but may be easily 

 distinguished by the form and colour of the genital aperture.

The colour of the cephalothorax is dull yellow (slightly 

 tinged with orange-brown) margined with a black line, and 

 more or less suffused on the sides (towards the margins) and 

 at the thoracic junction with blackish. All the rest of the 

 fore part is also of a similar colour, excepting the tibia3 of the 

 first and second pairs of legs, which are deep yellow-brown, 

 and the sternum, which is strongly suffused with blackish 

 brown. The metatarsi also of the legs above mentioned are 

 suffused, but less strongly, with yellow-brown.
