new and rare British Spiders. 197 



the middle of the hinder extremity is a short red-brown, some- 

 what tooth-like, pointed prominence, whose point is directed 

 outwards. The palpal organs are highly developed and 

 complex ; a strong somewhat pointed process, with its inner 

 edge minutely serrated, projects prominently downwards from 

 near their centre ; and at their fore extremity on the outer 

 side is another short strong one, of a black hue, whose ex- 

 tremity appears to be subdivided into several short divergent 

 projections. 



The Juices are similar in colour to the cephalothorax, mode- 

 rately long, powerful, vertical, slightly divergent at their 

 extremities ; and each falx has a strong, sharp-pointed, tooth- 

 like process in front, towards the fore extremity on the inner 

 side. 



The maxilla! are strong, especially at their base on the 

 outer side, where the palpi are inserted, obliquely truncated 

 at their extremity on the outer side, and strongly inclined 

 towards the labium j the latter is short, and of a somewhat 

 semicircular form. 



The abdomen is oval, rounded before, pointed behind, and 

 moderately convex above ; it is of a dull sooty yellowish- 

 brown hue, clothed thinly with coarse blackish hairs. 



This spider is allied to Neriene livida, Bl., but may easily 

 be distinguished by the tooth-like process on the falces, and 

 the absence of the red-brown impressed spots on the upper- 

 side of the abdomen, as well as by the totally different struc- 

 ture of the palpi and palpal organs. It is also allied to 

 Neriene (Drepanodus) aTbipunctata, Cambr. ; but the bifid 

 termination of the tooth-like process on the falces of the 

 latter, the armature of the tibiae of the first and second pairs 

 of legs, and the wide separation of the fore-central eyes, will, 

 with some other important differences, distinguish the present 

 species at once from that spicier. 



A single example of the adult male was found under a 

 stone at Ringstead (on the coast between Weymouth and 

 Whitenose), in April 1879, by my nephew, Frederick O. P.- 

 Cambridge. 



Neriene rudis, sp. n. 



Length of the adult female rather more than 1^ line. 



The profile of the upper part of the caput of this spider 

 forms a strong curve, the occipital region being considerably 

 convex ; the lateral constrictions on the lower margins of the 

 caput are but slight. 



The colour of the ceiilialothorax is a bright shining yellow- 

 brown ; the legs (which are tolerably long, rather slender,
