CLEVELAND SPIDERS. 
J. W. H. HARRISON, B.Sc., 
Middlesbrough. 
During the past winter I have had exceptional opportunities- 
of investigating the Arachnid Fauna of some of the more 
remote Cleveland dales and have been able to extend the 
known range of several of the rarer and more critical species. 
The localities visited were Farndale, Westerdale Moor. 
Basedale, Bilsdale Head, Greenhow Botton, Easby Moor. 
Great Ayton Moor and Eston Moor. In addition I have made 
a journey to the coast and have included the spiders noted 
then, together with one or two captures made near to the town. 
Spiders which were practically ubiquitous have been placed 
in a general list at the end of the paper. 
Theridion tepidariorum C.L.K. — Common in older green- 
houses near and in Middlesbrough. 
Pholcomma gibbum West. — I found a very curious example 
of this species, which at first I thought would prove to be a 
new species. It occurred on Great Ayton Moor. 
Onesinda minutissima Cb. — Very abundant in Farndale. 
on Kildale, Eston, Great Ayton and Easby Moors. I cannot 
accept the suggestion ( The Naturalist, 1913, page 135) that 
this is rarer in the Cleveland area than in the south-west of 
the county. It could not be more abundant than it is in all 
the above localities. The spider is a typically northern and 
sub- Alpine form, as both its British and Continental localities 
indicate. Most certain it is not of Western origin. 
Further, its stations in our islands coincide with those of 
such typical northern lepidoptera as Oporabia autumnata, 
Larentia caesiata, etc. 
Tapinopa longidens Wid. — Eston and Great Ayton Moors. 
Floronia frenata Wid. — 1 $ Saltburn. New to my local list. 
Linyphia pusilla Sund. — Farndale, Eston Moor. 
Linyphia hortensis Sund. — Farndale, Greenhow Botton, 
Turkey Nab, Great Ayton Moor. 
Leptyphantes minutus Bl. — Marton. 
Leptyphantes leprosus Ohl. — Bilsdale Head. Fairly com- 
mon. 
Hillhousia misera Cb. — Quite common. Farndale, Great 
Ayton and Eston Moors. 
Bathyphantes gracilis Bl. — Eston and Great Ayton Moors. 
Rather common. 
Bathyphantes pare ulus West. — Great Hograh, Westerdale, 
Eston, 4 <j(J. 
B. approximatus Cb. — Eston. Not uncommon. 
Porrhomma montanum Jacks. — Farndale. Common.
