94 Ptev. F. O. Pickard-Cam bridge on 



Paljms very characteristic. Humeral joint clavate ; cubital 

 as long as broad, convex, prominent in front, bearing at its 

 apex a single, stout, sinuous spine, tapering to a fine point, 

 and directed forwards over the base of the digital joint. 

 Iladial joint broader in front, produced beneath on the outer 

 side into a blunt spur. 



Digital joint ])roduced at base into a dark spur, hollow 

 beneath, terminating in a little rounded cariniform promi- 

 nence (PL 1. fig.ld, b). The falciform process is immensely 

 developed, forming a huge concave process, its lower spur 

 deeply bifid and extending outwards and upwards. The 

 palpal organs themselves present some complex black pro- 

 cesses, variously curved and pointed, with a more conspi- 

 cuous, stout, circular black spine at their apex (PI. I. 

 fig. la, a). 



A single adult male of this fine species was captured on 

 the summit of Ben Nevis in the autumn of 1S92 by 

 Mr. Edward Whymper, and kindly forwarded me by Mr. K. 

 I. Pocock, of the South Kensington Museum. 



It is a very interesting species, approaching as it docs very 

 closely to the genus Taranucnics, Sim. 



The straight posterior row of eyes, however, prevents it 

 entering that genus as at present characterized, although the 

 length of the legs, the form of the cubital joint with its spine, 

 and the structure of the palpal organs render it ditficult to 

 separate it. 



I have great pleasure in connecting Mr. Whymper's name 

 with this handsome spider. Ben Nevis, Scotland ; autumn,

Genus PORRHOMMA, Simon. 



This genus Porrhomvia may be considered as forming a 

 convenient " refuge for the destitute" for those spiders wiiose 

 characters seem to place them intermediate between Lepthtj- 

 phantcfi on the one hand, and 2\neticus on the other; and of 

 these it may be noted that P. cavicula, Sim., and P. erranSy 

 Bl., by the possession of a single metatarsal spine aj)proach 

 the former genus, while P. adipatum, L. K., and P. }noiiti(/eiia, 

 Sim., incline towards the latter. 



I have lately been enabled, by the courtesy of various col- 

 lectors, to examine specimens, in many cases the original 

 types, of a number of somewhat obscure species, variously 

 cliaracterized under the generic uixmL's Liiii/p/iia and -.Ver/c^ti, 

 all of which aj)pear to be more naturally included under the 

 genus Porr/iom/na, and some of which cortaiidy do not ditfer 

 specifically inter ac.
