NEW AND RARE YORKSHIRE SPIDERS. 
WM. FALCONER, 
Slaithwaite, near Huddersfield. 
ALREADY during the present year, fourteen species of spiders 
have been added to the Yorkshire list, bringing the total for 
the county up to three hundred and ten, a number only 
exceeded in the case of Dorset, though very closely approached 
by both Northumberland and Cumberland. 
For five of these additions, Entelecara thorelli: Westr, 
fig. 4, Hypselistes jacksonii Camb., Hypselistes nov. sp., 
Troxochrus ignobilis Camb., and Xysticus sabulosus Hahn, Mr. 
J. W. H. Harrison of Middlesborough is responsible, and he will, 
in due time, record particulars of them. They are all from 
Eston in the North Riding. 
Three others, with several species of some rarity, were 
obtained in the course of a day’s collecting on June 3rd last, 
by Mr. W. P. Winter and myself, from Selby by way of the 
river bank and Riccall Common to Skipwith Common, the 
well-known naturalists’ resort in the East Riding. The 
journey was undertaken with the express intention of investi- 
gating its arachnidal fauna more fully than had been hitherto 
attempted. Circumstances favoured us; the dry sunny 
weather which had prevailed so long, by drying up the moister 
portions of the Common, and contracting the waters of the 
Mere, gave us easy access to places which, in a wetter season, 
would be unworkable. It was only possible, however, to 
search a small area in the short time at our disposal, and many 
more visits at every season of the year will be necessary before 
its spider population can be satisfactorily ascertained. The 
remaining five species new to the list occurred in various parts 
of the West Riding. 
In the list, uninitialled entries indicate that the spider 
was of my own collecting.
