Hull: Northumbrian Coast Spiders.

L. nemorale Bl. at the same time and place ; but, unlike that 

 species, it does not appear to ascend into the hills. Its upward 

 limit in Allendale seems to be about 700 feet. 



Two other rare spiders have since been sent to me from the 

 tidal drift — Typhochraestiis cHs;itatus Cb., a fine pair from the 

 same spot as the spiders noted above (October 1908), the second 

 occurrence of the female in the county, and the first of the male ; 

 Cnephalo cotes elegans, both sexes (Ma^^ 1909- -just through the 

 last moult) from Cresswell, the second record of the male for 

 Northumberland and the first of the female. 



The characteristic spiders of the sandhills (as distinguished 

 from the comparatively level links on the landward side of them) 

 are Clubiona phragmitis C.L.K., Tibellus oblongus Wlk.. and 

 Trochosa picta Hahn. Along with these are swarms of Lepty- 

 phantes tenuis BL, /.. blackxcallii Kulcz., and Meta scgmentata 

 Clk., which, though they may be found almost anywhere, are 

 particularly abundant among the marram grass. 



Very few of the spiders occurring on the links have any claim 

 to be considered distinctiveh' littoral, but several species appear 

 to flourish better there than elsewhere. Among these may 

 be mentioned Oonops pulcher, Pholcomma gibhum, Bolyphantes 

 hiteolus, Gongylidium apicatum, Neriene bituberciilata, Tiso 

 vagans and Arceoncus humilis. 



The two species of Erigone and Tmeticus reprobus Cb. are 

 the only spiders which are exclusively maritime. The former 

 occasionally wander to some little distance inland, but T. 

 reprobus seems to be confined to the immediate neighbourhood 

 of high water mark, where it is to be found under loose stones. 

 It is generally distributed around the British Isles, but not yet 

 recorded for the mainland of Europe.
