DEAN : LAND AND FRESHWATER SHELLS OF MORECAMBE AND DISTRICT. 35 



500 feet, but these are always in the wooded hollows between the 

 moors. These are Vitrea cellaria, V. alliaria, V. nifidula, Zo/iitoiJes 

 excavnfiis, and Pyrainidiila rofundaia. The district is extremely bad 

 to work, and some of the likely localities difficult of access. Dolphin- 

 holme Bottom is a nearer locality where these five and one or two 

 other species occur together, and is fairly typical also. As a parallel 

 instance, I may mention that close to the famous Aira Force in Gow- 

 barrow Park, Ulleswater, Cumberland, the same five species occur 

 together. 



It follows, from the nature of limestone, that there is little to be got 

 in the way of freshwater collecting, except at Haweswater Tarn at 

 Silverdale. I should mention also Hale Moss as the habitat of some 

 exceedingly fine Succinea oblonga, and I should like further to add 

 that at both these localities are to be seen the Chara Marl deposits 

 already mentioned in the pages of this Journal. For freshwater 

 species there is no finer locality anywhere than the canal, especially 

 at the aqueduct or at Deep-Cutting near Lancaster. Specimens of 

 certain species are to be obtained at these two places, in the early 

 months of the year, which are finer than those found anywhere else 

 in the district. 



I have given in the subjoined list in many instances the month of 

 the year during which mature specimens are best obtained. Those 

 taken later have, in several cases, proved to be smaller and more 

 stunted than the earlier-matured specimens. 



I have very great pleasure in tendering my best thanks to Messrs. 

 A. S. Kennard, F.G.S., Robert Standen, H. Beeston, J. Wilfrid 

 Jackson, C. H. Moore, and others, for tlie very kind assistance I 

 have received during the preparation of these notes. To Mr. 

 Kennard I am very much indebted for allowing me to make use of his 

 information in regard to Hygromia sericea., and for his efforts which 

 have led to the right identification of the Hale Moss SucdnecB. I am 

 also much obliged to Mr. Standen for allowing the insertion of the 

 Grange and Caton records, which carry his initials ; and also to Mr. 

 Jackson for the identification of several of the slugs, and for many 

 localities.
