the legs and palpi reddish-brown, and the abdomen black. The 

 caput is moderately elevated, the lower part of the clypeus is 

 prominent, and there is a longitudinal indentation running back- 

 wards from each lateral pair of eyes. The hind-central pair of 

 eyes are near the fore part of the summit of the elevation, and 

 the other three pairs are placed, in a transverse line, less than 

 half-way between the central pair and the lower margin of the 

 clypeus. The radial joint of the male palpus is produoed at 

 its inner extremity, and has a short, pointed apophysis at its 

 upper one ; the palpal organs are prominent and complex, with 

 a very long, convoluted, slender, filiform spine, which springs 

 from their fore part ; the digital joint is of unusual form, being 

 broad, but deeply, roundly, and broadly impressed, or hollowed 

 out, at its fore extremity, the hinder extremity being quite 

 narrow. 



This is a rare spider, but it occurs occasionally among moss, 

 and undor stones, as well as on underwood, at Bloxworth, in 

 spring and early summer time. It has also been found in North 

 Wales and Scotland. 



WALOKENAERA OBSCURA. 



Walokenaera obsouea, Blaclcw., Spid. Great Brit, and Irel., p. 

 297, pi. xx., fig. 212. 



The length of the male is l-14th of an inch. 



This spider is allied to the last, but is not difficult to be distin- 

 guished from it. The cephalo-thorax is of a deep, rich, black- 

 brown colour, the legs dull yellowish red-brown, and the abdomen 

 black. The elevation of the caput is very distinct, though not 

 very high (resembling somewhat that of Walokenaera fuscipes); it 

 is placed more on the occiput than that of Walokenaera pumila, and 

 the longitudinal indentations behind the lateral pairs of eyes are 

 much exaggerated, forming strong, deep, lateral compressions, and 

 thus marking off the elevation more distinctly. The caput is 

 glossy, but the thoracic region is of a dull hue, slightly roughened 

 on the surface, whence it has boon mimed by M. Wostriug, au
