66 ON SOME RARE ARACHNIDS 



is practically straight, and so is the posterior row seen from 

 above. The facies of these spiders is quite different, as one 

 would expect. The vulvae, however, are so dissimilar that 

 there is not the slightest difficulty in distinguishing the species 

 by those structures alone. I here figure the vulvae of both. 



Styloctetor uncinus (Camb.)* 

 Styloctetor broccha (L. Koch — Carp.)f 



In 1904 I obtained several examples of a small spider by 

 shaking moss on the summit of Scafell Pike. These were 

 described by Mr. Cambridge under the former of these names. 

 In 1905 the same species occurred to me in similar situations on 

 the summit of Snowdon. Last year Dr. R. de Lessert kindly sent 

 me some specimens of .5. broccha (L. Koch) from Switzerland. 

 These were strikingly unlike the British species. I dispatched 

 a pair of Cumbrian examples to Dr. G. H. Carpenter, who 

 compared them with the Irish specimen described under the 

 latter name. He states that the two supposed species are 

 identical, and therefore as S. broccha (Koch) is quite different 

 from either of them, its name must, for a •time at all events, 

 disappear from the British list. 



In addition to the above, the following interesting x'\rachnids 

 have been observed during the year. 



ARANE^ 



Prosthesima rustica (L. Koch). Mr. Bennett obtained 

 an adult male at Hastings in May. It was found on the 

 cliffs at the roots of herbage. 



Drassodes sylvestris (BL). An adult male was found at 

 Guestling near Hastings in April. Its captor, Mr. Bennett, 

 found it amongst dead leaves. 



Drassodes pubescens (Thor.). I found a single male 

 amongst herbage at Beer near Sidmouth in June.
