A SEPTEMBER WALK THROUGH LANCASHIRE, 

 CHESHIRE, AND STAFFORDSHIRE. 



T. D. A. COCKERELL, M.C.S. 



Chiswick. 



Having recently had occasion to go to Liverpool, I determined to 

 make the most of my opportunity, and get a glimpse of North of 

 England natural history. I accordingly walked from Liverpool as far 

 as Froghall, in Staffordshire, making observations on the way. My 

 attention was chiefly devoted to conchology, and I only noted such 

 of the other forms of life as forced themselves upon my attention, 

 generally in contrast to the more familiar South. The lists of mollusca 

 given below are arranged in the order in which they were found, and 

 hence the first mentioned will in most cases be the commonest in 

 that particular district. 



September 9th, 1885. — Before starting from Liverpool I visited 

 the Museum. The collections here, although small, are very well 

 arranged and neatly put up — in this respect far superior to those in the 

 Museum at London. I noticed in the collection a sinistral example 

 of Helix pomatia, supposed to be British. There is a similar but 

 smaller 'British' example in the London Museum, but for the present 

 perhaps it would be best not to include this form in the British fauna 

 on the strength of two examples, the precise locality not being stated 

 in either case. There are also some curious examples of Helix 

 nemoralis from Oporto, one of them being purplish-fawn, with a 

 formula 00345, and another yellow and bandless. 



I will now commence the account of my walk. 



LANCASHIRE. 



Liverpool to Prescot. — The Mollusca observed were : — 



Limax agvestis, type. Hyalina cellaria. 



, , v. sylvatica. Helix concinna. 



Avion hovtensis v. fasciata. Hyalina nitidula v. nitens. 



Helix votundata (abundant). Avion atev v. vufa. 



Hyalina nitidula. Limax agvestis var. (*) 



Helix votundata v. pyvamidata (one). Cochlicopa lubvica. 



H. hispida. Avion hovtensis var. ( 2 ) 



Hyalina alliavia. 



The variety of L. agrestis ( 1 ) was entirely dark greyish; that oiArion 

 hovtensis ( 2 ) was greenish yellow, with a yellow mantle and scarcely 

 perceptible bands. I found several specimens, all alike. 



I noticed the larvae of Spilosoma lubricipeda Esp., and of S. men- 

 thrastri Esp.
