ARACHNIDA OF THE SAWLEY DISTRICT. 
WM. FALCONER, 
Slaithwaite, Huddersfield. 
A visit to the above district from May 22nd to May 25th last 
enables me to add considerably to the list given in the Naturalist 
for July, pp 232-3, the species of spiders being increased to 
123, and of harvestmen to 4. A few mites were also noted. 
The locality with its varied surface features gives every 
indication of being a very productive one as regards arachnids, 
but game restrictions prevented me from collecting over much 
suitable ground, and limited time permitted only imperfect 
investigation elsewhere. With the exception of Hahnia pusilla 
C.L.K., and Centromerus arcanus Camb, the species recorded 
loc. cit.—-(inclusive of Meta menardi Latr., another fine male of 
which was boxed on the roof of Ned Hole)—-were again met 
with, and in many instances additional stations obtained for 
them, while to the rare British spiders there noted may now be 
added the following :—-illhousia misera Camb., Diplocentria 
rivalis Camb., Sintula cornigera Bl., Notioscopus sarcinatus 
Camb., and Tapinocyba insecta L. Koch. Notioscopus, origin- 
ally discovered in marshy ground in Bavaria, then in France, 
has more recently been found in Cleveland ; its wide distribu- 
tion in the last named area, and its occurrences on Sawley High 
Moor remove all doubt from my mind as to its being indigenous 
to Britain.* Tapinocyba insecta L. Koch has been previously 
reported from Western and Central Europe and in these islands 
from Hexham, Leeds, Huddersfield, Bexhill and Ireland. So 
far as at present known, a few others seem to occur only in- 
frequently or locally in the county, e.g., Anyphena_ accentuata 
Walck., Onesinda minutissima Camb., Linyphia pusilla Sund., 
Leptyphantes tenebricola Wid., L. flavipes Bl, Entelecara 
trifrons Camb., Chiracanthium carnifex Fabr., and Porrhomma 
pbygmeum Bl., while P. montanum and pallidum Jacks., were 
until quite recently confounded together under a third name, 
P. oblongum Camb., which rightly belongs to neither,. 
Mr. Margerison not only gave invaluable assistance in 
collecting, but also placed his intimate knowledge of the topo- 
graphy of the district freely at my disposal. 
The species marked with a dagger were obtained by him 
only, those with an asterisk by both, and the unmarked ones 
by the writer only.
