A COLLECTING TOUE IN NOETH YOEKSHIEE. 



By H. Pollard. 



Early in the present summer we set out on a Natural History 

 collecting tour in the north of Y'orkshire. As a conyenient starting- 

 point Whitby was chosen, with the intention of extending the work 

 which has already been done there. 



On the morning after our arrival we began early in excellent spirits 

 our work of collecting, which we continued vigorously and success- 

 fully the whole of the time we remained in this locality. As it is of 

 but little use to enumerate the whole of the shells and beetles we 

 took here, many of them being mentioned by Mr. Crowther in his 

 article on Whitby," we will only give those which are additional. 



In land and fresh-water shells we collected Biilimus ohsciiriis and its 

 variety alha ; this last is very rare, and occurred but sparingly. In a 

 ditch near Larpool fine elongated specimens of Limncea truncatula 

 were taken. Another shell worthy of notice from its peculiar shape, 

 was Limncea peregra^ taken near the small but picturesque village of 

 Euswarp. Helix nemoralis var. liortemis appeared in profuse numbers, 

 and with it were found several splendid specimens of the variety 

 liyhrida. 



In marine conchology we took, on the scar at Saltwick and at a 

 distance of about two hundred yards from the shore, specimens of 

 T'aves pullastra ; they were veiy dwarfed in size, and attached to the 

 rocks. Other beautiful shells fonnd here were Tedura testudinaiis and 

 Trochus helicimis. Eespecting the former, in the article already cited 

 mention has been made of its probable occurrence at Eobin Hood's
