 V. pellucida. Mr. Alder, Catal. 

 The distribution of this species over our island appears to be 

 very extensive. It is also mentioned in the Appendix to Welsh 

 and Whitelaw's History of Dublin, under Captain Brown's name 

 of Helix ellipfica, as found at Ferbane and other parts of that 

 neighbourhood. The animal has the same carnivorous pro-

 detected no less than seven individuals busily engaged in feed- 

 ing on a scarcely dead earthworm, which was faintly writhing 

 about, and endeavoured in vain to get rid of its assailants.

In addition to the locality before mentioned, I have to add 

 that I lately found a single specimen on Mount Edgecumbe near 

 Plymouth. It is an intermediate species between the last and 

 the Helix diaphana of Draparnaud. 



V. elongata, p. 327, lege Dillwynii, Jeffreys. 



This being a different species from the V. elongata of Drapar- 

 naud, I have ventured to dedicate it to my much esteemed

 author of several standard works on natural history.
