B.D. brought the var. exalhida of Helix aspersa from Skipsea 

 Brough, and a number of marine shells were collected by 

 various members. 



Arachxida. — Mr. T. Stainforth writes that the following 

 spiders, identified by the Rev. O. Pickard Cambridge, F.R.S.. 

 were obtained in the neighbourhood of Hornsea Mere by Messrs. 

 H. C. Drake, E. A. Parsons, J. Porter, A. C. Willford and him- 

 self. Of these, eighteen (marked with an asterisk) are new to 

 the published East Riding List,* and three (marked f), new to 

 the Yorkshire List. Most of the species are common, the most 

 rare and interesting, Mr. Cambridge writes, being Tmeticus 

 affinis Bl., as Blackwall's two original type specimens came 

 from Hornsea.
