ON BRITISH ARACHNIDA. 105 



Centromerus areanus, Cambr. 



Adults of both sexes received in May, 1908, from Mr. W. 

 Falconer from near Huddersfield. 



Centromerus prudens, Cambr. 



Received from Snowdon and from Snaefell (Cumberland) 

 in 1908 from Dr. A. R. Jackson. 



Mieroneta saxatilis, Blackw. 



Microneta passiva, Cambr., female (non male), Proc. 



Dors. N.H. and A.F. Club, XXVII., pp. 77, 89.

 of M. passiva, Cambr., turns out to be that of M. saxatilis, 

 Blackw.

Gongylidiellum vivum, Cambr. 



An adult female received in July, 1908, from Mr. D. R. P. 

 Beresford, by whom it was found in Ireland. 



Gongylidiellum mureidum, Sim.

 locality in the New Forest, in June, 1908. One British record 

 only existed, previously to my meeting with both sexes in 

 the Forest in June, 1895, of an adult male, Wicken Fen, 

 Cambridgeshire, some years previously. The occurrence of 

 the female also, in the Forest in June, 1895, was accident- 

 ally omitted in my note in Proc. Dors. N.H. and F. Club, 

 1895, p. 125. Probably a little assiduous collecting would
