164 ON NEW AND RARE BRITISH SPIDERS. 



markings, and the form of the genital process differs distinctly 

 from that of Z , JSIengii. 



One example only of each sex taken some time ago at 

 Bloxworth. 



I had thought it possible that this Spider might be the 

 Leptyphantes Henrico:, Kulcz., described and figured by Prof. 

 Kulczynski in his " Aranese Hungarise ; " but from examples of 

 that species, just received from Prof. Kulczynski, it appears to be 

 quite distinct. Prof. Kulczynski considers that his Z. Henricce is 

 identical with Z. JJavipes, BL, but of this I am not quite 

 convinced. We have now five exceedingly closely allied British 

 species of this genus, Z. tenuis, BL, Z. tenebricola, Wid., Z. 

 flavipcs, BL, Z. Mengii, Kulcz, and Z. acceptus, Cambr. ; the 

 difficulty of separating and determining them is great ; what is 

 needed towards this is a series of each from many localities.

 Irish Spiders, p. 28. 



Adult female, length jfrds. of a line. 



This sex is coloured like the male ; the whole of the forepart 

 is yellow, sometimes inclining to orange. The abdomen black. 

 The genital process is large and of very characteristic form. 

 The legs are long, slender, and instead of the usual single spine 

 on the metatarsi of the first and second pair this species has 

 several, apparently 5-6. The female now described is new to 

 science. 



Both sexes, adult, taken on the top of Scafell, Cumberland, 

 were received from Dr. A. R. Jackson in 1902. 



Gong-ylidium distinetum, Sim. Fig. 6. 



The female of this species does not appear to have been 

 hitherto described or recorded. It is a little larger than the 

 female, but resembles it in general characters and colouring.
