NOTES ON ARACHNIDA ON THE NORTH EAST 

 COAST OF YORKSHIRE. 



vvm. falconer, 



Slail!ni.'aiic, Huddersfield. 



As the result of another visit to the North-east Yorkshire coast 

 in August of the present year, I am able to add to the list of 

 Arachnida given for that district in ' The Naturalist,' January, 

 1910, pp. 21-2, the following species. .4. — Nine spiders and one 

 har\'estman new to the N. Riding and B — twenty-two others for 

 which additional records, either for the county or North Riding, 

 are desirable. Most of last year's species were again met with, 

 but although I went twice to Eston Moor, and spent a con- 

 siderable time in the search, I failed to locate the spot where 

 ]\Ir. J. \\\ H. Harrison, of Middlesborough, obtained the two 

 remarkable spiders both new to the British list, and recorded 

 by the Rev. J. E. Hull in ' Some Northern Records,' in Trans. 

 Nat. Hist. Society of Northumberland, Durham, and Newcastle- 

 upon-Tyne, Vol. III., pt. 3, viz. : Hypselistes fiorens Camb., 

 a North American species, found nowhere else in Europe, and 

 Notioscopiis sarcinatus Camb., a Central European spider, 

 concerning both of which their discoverer holds strong opinions 

 as to their being indigenous to Britain, and not merely intro- 

 ductions. I found Kilton Wood the best hunting ground, 

 and my thanks are due to Mr. J.J. Burton, Nunthorpe, for 

 permission to enter it. 



.4. New to the North Riding. 



ScotophcBUs hlackwallii Thor., one adult female in a 



cranny of the outer wall of a wash-house in St. 



Germain's Lane, Marske. Odd examples are on 



record for the other Ridings. 

 Clnhiona terrestris \\'estr., both sexes, Riftswood, 



Saltburn, and Kilton Woods. Few records for 

 i county. 



Clnhiona grisca L. Koch., males at Coatham ^larshes, 

 ; and near Tees Movith. Few records for county, 



* mostly from E. Riding. 



: Clnhiona neglecta Camb., females, Marske and near 



Tees Mouth. Rare in Yorkshire, mosth' reported 



from E. Riding. 

 Rohertns arnndineti Camb., one male, Coatham 



Marshes (with one abnormal palp). Three 



examples previously reported from ^^^ Riding. 



1910 Dec. I.
