appearanco in the profile line. The palpi are short ; the radial 

 joint is broad and strong, and has three apophyses, a rather long 

 slender one curved outwards in front of the digital joint, a strong 

 crescent-shaped one in front, towards the outer side, and a short 

 obtuse one underneath; the digital joint is large, and the palpal 

 organs complex ; a black filiform spine is curved in a circular 

 form noar their middle, and from within its curvaturo, a black, 

 slightly cork-screw-shaped spino, onvoloped in membrane, is 

 dirocted obliquely forward and downwards. The female is rather 

 larger than the male, and resembles it in colours, but the caput 

 is less elevated. 



Adults of both sexos of this rare spider were found under 

 stones and pieces of rock at Portland, near Pennsylvania Castle, 

 in July, 1860. It is allied to Walckenaera antica, Wid., and also 

 to the next species described. 



WALCKENAERA ATRO-TIBIALIS. 



Walckenaera atro-tibialis, Cambr., Ann. and Mag. N.H., s. 5, 

 vol. 1, p. 116, pi. 11, fig 3. 



The length of the female is one line. 



This spider is nearly allied to the foregoing as well as to 

 Walckenaera antica, "Wider. ; from both, however it may be dis- 

 tinguished by the tibiso of all the legs being black, instead of, 

 as in those species, the tibia) of the two first pairs only. The 

 transverse depression behind the caput is stronger than that of 

 the female of Walckenaera saxicola ; and the colours of the spider 

 are far less vivid than those of Walckenaera antica. 



A single example only, found in Berewood near Bloxworth, 

 among moss and dead leaves in June, 1876.
