yellowish liuo. The palpi are moderatoly long ; the cubital joint 

 is clavate and slightly curved; the radial joint is short, hut 

 broadly and greatly produced over the digital joint, the greater 

 part of which it conceals. The produced part narrows gradually 

 to a curved, prominent, and obtuse extremity, which is directed 

 upwards, i.e., away from the digital joint. The palpal organs 

 are prominent and complex, with a prominently, curved, black 

 spine, in contact with some semidiaphanous membrane, beneath 

 their fore extremity. The abdomen is black. 



A single example of this very interesting spider was found on 

 the lawn at Bloxworth Rectory by my son (Robort Jocelyn), in 

 May, 1877. This is its first record as a British spider. One 

 examplo only, from Bavaria, had previously come before mo.

Tho male of this very distinct species measuros 1 line in length, 

 and the female is rather larger. 



The caput is rather elevated, porrected, and divided at its fore 

 extremity into two segments, by a deep, transverse groove, or 

 indentation ; each segment is clothed at its summit with 

 numerous hairs meeting over the indentation and forming a 

 crest. Tho posterior segment bears the hind-central pair of eyes, 

 and the antorior segment the fore-contral pair, the lateral pairs 

 being much lowor down below the cleft. Tho falces are placed 

 far back, and are much inclined to the sternum. 



Thecolourof the cephalo-thorax is brownish-black, the legs and 

 palpi red-brown, and tho abdomen glossy-black. The palpi are 

 moderately long ; the cubital joint is of a clavate form, and the 

 radial joint is broadly and obtusely produced over the base of 

 the digital joint with a curved, spine-like, pointed process, 

 directed outwards from its inner extremity. 



This is by no means a common spider, but isfound occasionally 

 at Bloxworth, and in the neighbourhood, among lichens on apple
