of a dark blackish yellow-brown hue. The female is rather 

 larger than the male and resembles it in colours, but is wanting 

 both in the elevation of the caput, and the coriaceous covering of 

 the abdomen. 



Found occasionally in autumn, and spring, among moss and 

 lichens on apple trees at Bloxworth, as well as in Scotland and 

 North Wales. 



In its general form it bears considerable resemblance at first 

 sight to Walckenaera lifrons, Bl., but the present species is smaller 

 and differs in colours. The hind-central pair of eyes also are 

 placed on the fore part of the summit of the elevation of the 

 caput, a long way from the rest, while in Walckenaera lifrons 

 they are seated on the front of it, close above the other eyes.

Length of the male 1-1 8th of an inch. 



This very distinct species cannot be mistaken for any other as 

 yet known in Great Britain, being of an almost uniform pale 

 dull brownish yellow hue. 



The elevation on the caput is strong and high, slightly exceed- 

 ing half the total height of the caput ; it is also strongly inclined 

 backwards; the hinder part is well rounded, the summit also 

 rounded and broader than the base, and the front flattish; the latter 

 slopes in the same line as the clypeus, which is considerably 

 prominent a little way above the lower margin. The colour of 

 the elevation is clouded with brown. The palpus of the male 

 is rather short and slender ; the radial joint is much shorter 

 than the cubital, but broader ; it has a short, pointed apophysis 

 at the fore extremity on the upper side, and both the outer and 

 under side are rather prominent. The digital joint is not large, 

 and the palpal organs are prominent and complex, with a curved
