Spiders new to the British Fauna. 203 



Bavaria. M. Simon records the spider from both the north 

 and south of France and from Corsica, while MM. Chyzer 

 and Kulczynski found it on the Croatian shore of the Adriatic 

 (Fiume). It seems therefore to belong to a southern distri- 

 butional type. 



This is the fourth species of Cnephalocotes which has been 

 added to the British list within recent years. The genus was 

 represented in our fauna only by C. obscurus (Bl.) * until 

 1888, when Mr. Cambridge described as a new species 

 C. interjectus f from Hertfordshire ; this spider, lately 

 recorded from the Edinburgh district \, is now believed to be 

 identical with C. kesus, L. Koch §, from Central Siberia. In 

 1894 two more species of Cnephalocotes — C. curtus, Simon, 

 and C. elegans, (Jamb. — were added to the British list ||, the 

 former occurring on the shores of the Firth of Forth, the 

 latter in Inverness-shire. C. curtus has since been found on 

 the west coasts of Scotland and Ireland ^[. C. situs makes, 

 therefore, the fifth species of the genus known to inhabit our 

 islands. 



The species of Cnephalocotes are small dark- coloured spiders 

 with strongly chitinized skin and short blunt carapace ; eyes 

 small, those of the hinder row moderately procurved, the 

 centrals nearer to each other than to the laterals **. The very 

 wide sternum is produced between the hindmost haunches in 

 a broad, blunt, rounded process. The legs are short and stout, 

 the front tarsi being fusiform (especially in the male) and 

 nearly as long as the metatarsi. The tibia of the male palp 

 is usually broad and truncate, with one or two short processes ; 

 the tarsus is always large and the bulb prominent, with a free- 

 ended, coiled, thread-like spine. 



The males of our British species may be tabulated thus: — 



I. Head-region more or less elevated, distinct impres- 

 sions running backward from lateral eyes.

** In the large and closely allied genus Lophocarenum, Menge, the eyes 

 of the hind row are equidistaut and the row greatly procurved ; also the 

 skin in Lophocarenum is more strongly coriaceous.
