Yorkshire Naturalists at Cai&thorne. 



395 



corticalis Walck. were obtained. For the last two there are 

 only two other Yorkshire records. From the yews growing 

 by the side of the drive leading into Deffer Wood were beaten 

 a few immature specimens of both sexes of Epeira sturmii 

 Hahn. This is the first definite Yorkshire record of this spider. 

 In the wood itself, a wet spot yielded Bathyphantes approxi- 

 matus Camb., one female (new to West Riding) ; the bracken 

 debris produced (Edothorax agrestis Bl., Tapinocyba pallens 

 Camb, and Wideria cucullata C. L. Koch ; and on tree trunks 

 Drapetisca socialis Sund. abounded. The best finds of the day 

 however, were an adult pair of Ceratinella scabrosa Camb., and 

 a female Walckenaera, which has not yet been determined satis- 

 factorily, both new to Yorkshire. Altogether, forty-three 

 species of true spiders, five of harvestmen, and one of pseudo- 

 scorpions were met with. In the following complete list, A 

 denotes species obtained by both, B by Mr. Winter only, and c 

 by himself only.
