XLIII. — New and obscure British Spiders. 

 By the Rev. Fkedekick O. Pickard-Cambkidoe. 



[Plates XX. & XXL] 



Since my last contribution to the Ann. & Mag. Nat. Hist, 

 in January 1891 few opportunities have offered themselves 

 for working- the likely places in the Lake Districts. A 

 fortnight in the heart of the "Lakes" at Elterwater in July of 

 last year, however, enabled me to do a little among the 

 spiders, with the result that several rare and local species 

 came to hand, while one addition was made to the British 

 list — Lopliocarenum Afenc/ei, Sim. 



A few days at Cannock, Staffordshire, in May of last year 

 enabled me to add a fine species to science, Tmeticus simplex, 

 F. Cb., while another very small spider, which I believe to 

 be hitherto undescribed, turned up amongst some captures 

 made in Dorset in 1888. This I have called Leptyphantes 

 plumiqer, though its exact generic position is somewhat 

 doubtful. 



To these new forms Tmeticus Warburtonii, Gb., perhaps 

 ranks next in value ; it occurred in some abundance along 

 with its congener, Tm. scopiger, Grube, in Newton Moss, 

 Penrith. 



Other employments will not at present admit of my giving 

 figures and descriptions of several other forms which are 

 certainly new to science. Many of these are of the female 

 sex ; and though it is better to secure the males first, yet 

 perhaps the simplest plan will be to describe and figure these 

 as briefly and accurately as possible, trusting that time and 

 an increased number of workers will contribute greatly 

 towards finding partners for them. 



I have taken this opportunity of publishing a few notes 

 and figures of the differential characters of several obscure 

 and closely-allied species — Zilla atrica and Z. x-notata, 

 Amaurobiiis similis and A. fenestralis, &c. 



New Species added to the British List, and two new 

 to Science.
