8592 Arachnida. 



Legs moderately long and stout, clothed with hairs, and of a pale 

 yellowish brown colour, blackish at the articulations of the 

 joints. 



Falces short, powerful, and of a yellow-brown colour. 



Maxillae short, inclined towards the labium, and similar to the legs 

 in colour. 



Labium broad, short, semicircular, and, with the sternum, which is 

 broad and convex, of a black-brown colour. 



Abdomen short-oval, very convex, and much projecting over the 

 base of the cephalothorax. Its colour is a deep black-brown, 

 with a few obscure, pale, curved, transverse lines on the upper 

 side towards the spinners : these lines are only visible when in 

 spirits of wine. 



Palpi moderately long, same colour as the legs, except the digital 

 joint, which is darker. Humeral joint curved inwards. Cubital 

 joint long, rather bent downwards and clavate, notched at the 

 end on the outer side. Radial joint short and stout, produced in 

 front into a long strong projection, curving towards* the outer 

 side, reaching nearly to the end of the digital joint : the end of 

 this projection is dilated, and in the form of a crescent, whose 

 outer limb is broad, obtuse and dark-coloured ; the tip of the 

 lower limb is small, pointed and curved. Palpal organs highly 

 developed, but not very prominent nor complicated : a large 

 lobe at their base has its margin next to the radial joint, shining 

 and corneous : from their extremity issue several spines ; the 

 most conspicuous is a very strong corneous one, of a dark red- 

 dish brown colour, issuing from their extremity on the inner 

 side, and, curving across to and round their extremity, passes 

 round their outer side, and projects its sharp point into some 

 semitransparent membrane ; another smaller, slightly curved, 

 black spine, issues from within the curvature of the former one, 

 and projects its point into the same membrane. 



An adult female only differed in the less elevation of the ocular 

 region. 



I captured this species at Blox worth, in May, 1861, and for some 

 time mistook it for W. humilis, to which it is nearly allied, but from 

 which, however, subsequent examination has shown it to differ con- 

 siderably, especially in the form of the ocular region : this part, in 

 W. humilis, is less elevated, less prominent, rises more abruptly, is 

 more obtuse at its upper end, where it is truncated more in a
