Report of the Grange Ramble, June loth, 1908. 



A most enjoyable day was spent at Grange, on Whit-Wednesday last by a 

 party of members of the Conchological Society. Some fifteen persons, including 

 ladies, took part in the ramble, which proved on the whole fairly successful. 



As on former occasions, the habitat of Succinea oblonga at Low Meathop 

 Marsh was first visited to enable several of the members to personally collect 

 this interesting species. It proved fairly abundant in the damp ditches, at roots 

 of grass, &c., in the meadow, and under stones by the roadside, in all stages 

 of growth. The absence, however, of adult examples was noticed. The usual 

 percentage of perfect, but dead shells occurred as on previous occasions, and it 

 would be most interesting to discover what the causes of this are. 



As pointed out by the writer last year, some portion of the destruction of 

 this and other species might be attributed to the ordinary red centipede {Litho- 

 bius forficatus), a suggestion based on the fact of finding, on at least two 

 occasions, specimens of the latter in close proximity to cleaned out shells of 

 S. oblonga and others. Beetle larvse, slugs, and other species of mollusks, 

 especially Vitrece, might also be guilty of no little assistance in the work. 



Though occurring in good numbers in the meadow below, only very few 

 specimens of 5". oblonga were noticed on the cliff face and ledges, where last 

 September the writer obtained specimens at the height of twenty-five feet from 

 the ground. On the marsh the shells were very numerous in the mice runs, 

 and a haul of about twenty specimens was made on mice droppings. 



The numerous already recorded species occurred here and in the intermediate 

 neighbourhood, though perhaps not in such great abundance. An additional 

 fresh-water species was added to the list in the shape of Limnxa palustris. 

 laminia secale, an addition made by the writer last year, was much sought for 

 but failed to put in an appearance, owing to the dry state of the herbage, etc. 



With reference to the specimens of /aminia muscorum occurring here, a 

 fact which appears to have been overlooked on previous rambles is that the 

 great proportion of them is of the typical form, possessing a well-defined den- 

 ticle, deeply seated in the middle of the base of the last whorl. A few 

 specimens occur of the var. edmtula, and I obtained a specimen possessing two 

 denticles in the position usually occupied by the single denticle, and in this 

 respect differing from the var. bigranata Rossm., which has one denticle at base 

 of columella and another well within the outer lip. 



Though the type occurs at Meathop in such great abundance, the reverse is 

 the case across the Kent estuary at Silverdale, Warton, etc., and the prevailing 

 form is var. edentula, in fact one very rarely gets a typical specimen. 



Some nice specimens of Succinea elegans were obtained at the road-side on 

 the way back to Grange, and another specimen (dead) of Vitrea lucida fell to 

 the lot of Mr. J. D. Dean, at the original habitat on Lindale Road. Eggers- 

 lack Wood and the adjoining pasture were then visited and the usual quota of 

 species obtained. One of the party, Mr. F. H. Gripper, had the pleasure of
