Pisidium pusillum. 

 Plaiiorbis vortex. 

 Fliysa ]iypnorum. 

 Limnaa jiiabra. 



Zonites nitidus. I consider this 

 a misprint for Z. niiidulus. 

 Helix latiiellata. 

 Pupa marginata. 

 Helix coiiviniia. 



The last four are recorded as from a pond on Clapham 

 Common, a locaUty I tried to find but did not succeed. One 

 of the most interesting finds to me was Helix ericeioni??i, as I 

 never expected it to turn up, although I have found it in some, to 

 me, very unlikely localities, as on a grassy bank at Monsal Dale, 

 Derbyshire, and a colony in the middle of a wheat-field at 

 Morcott, Rutlandshire, in a steep part of the field that could not 

 be ploughed. I notice that the Rev.W. C. Hey mentions in 'The 

 Naturalist' for June, 1885, page 258, that he saw a few dead 

 specimens oi Helix encetonmi at the foot of Giggleswick Scar, 

 this would be about ten miles from Ingleton, so they may be 

 found elsewhere in the district. 



I was rather surprised that I did not find H. lapicida, as it 

 occurs so abundantly on the Limestone in Derbyshire. The 

 nearest locality to Ingleton, from which I can find any record is 

 Kilnsea Crags and Kettlewell in Wharfedale, mentioned by the 

 Rev. W. C. Hey in vol. iii. of ' The Journal of Conchology,', 

 page 178. Seeing that Ingleton is a district so rich in species, I 

 hope that the members of this society will organize an excursion 

 there during the coming season, and be able to add considerably 

 to the species I have mentioned.

Helix rupestris, an ovo-viviparous species. — On 

 looking through the H. rupestris I got at Ingleton I found one 

 of them, from which I had tried to extract the animal, shewing 

 in the mouth young shells with i^ or 2 whorls formed, em- 

 bedded in the part of the animal shewing there- In turning to 

 Jeffreys' British Conchology, I find this is an ovo-viviparous 

 species, which this shell shews very well, and on looking care- 

 fully over my remaining duplicates I am pleased to say I found 

 several more, all shewing the same feature. — Edward Collier.
