Abdomen jet-black, tliinlj clothed with short fine yellowish 

 hairs. 



The upper part of the caput is slightly raised above the 

 ordinary level, and presents a flattish summit, the middle of 

 which forms an oval distinctly marked by a surrounding 

 groove ; the hinder slope or occipital portion looked at in 

 profile is short and abrupt. The profile resembles in this 

 respect pretty nearly that of W. Beckii^ Cambr., and a not 

 very strong, small, narrow-oval, slightly curved indentation 

 or fovea runs backwards from just above each lateral pair of 

 eyes a little below and parallel w^ith the upper margin of 

 the caput ; in the middle of the ocular area are a few short 

 strong upturned hairs. The cephalothorax is short, almost 

 round, and the thoracic region is somewhat flat and its sur- 

 face rugose, while that of the caput is smooth and glossy. 



Eyes small and very indistinct, placed on the fore part of 

 the caput, one pair (the hind centrals) on the anterior edge of 

 the raised portion in a transverse line about a diameter apart 

 from each other ; immediately beneath them is a slight trans- 

 verse indentation, and just below each extremity of it is a 

 lateral pair placed obliquely, and midway between the two 

 lateral pairs (and contiguous to each other) is the fore central 

 pair. 



The height of the clypeus is about two thirds of that of the 

 facial space. 



Legs slender, not very long nor very unequal in length, 

 1, 4, 2, 3, furnished with very short fine hairs only. 



Palpi short, similar in colour to the legs, excepting the 

 radial and digital joints, which are dark yellow-brown. The 

 radial joint is similar in length to the cubital, but much 

 stronger ; it is of a rounded spreading form and has a short 

 bifid apophysis bent abruptly inwards at its fore extremity on 

 the outer side. The digital joint is rather large, oval. Palpal 

 organs highly developed, prominent, with several spines and 

 corneous processes ; a very long, slender, filiform spine issues 

 from the middle of their outer side and curves round beneath 

 with a long, free, sinuous, exceedingly slender, hair-like point, 

 and another short black spine is curved in a circular form at 

 their extremity. 



Falces small, conical, directed strongly backwards, and of 

 a deep yellow-brown colour. 



Maxillce and lahium of the ordinary form common to the 

 genus, and similar in colour to the falces. 



Sternum large, short, heart-shaped, convex, and of a glossy 

 •deep black-brown colour. 



An example of this distinct spider, which I have great
