Helix nemoralis in the Pyrenees. — Dming a short 

 stay at Eaux-Bonnes, in the Pyrenees, about 3,000 feet above 

 sea-level, I was struck with the large number of white-lipped 

 specimens of Helix nemoralis. This is an extremely common 

 species in the Pyrenees, and at the locality mentioned the dark- 

 and white-lipped varieties are equally common and generally 

 found under the same stone. The variety is, I think, the one 

 first recorded as British by Mr. J. W. Taylor under the name of 

 albolabiata Von Mart. (Jour, of Conch., vol. iv.). The \forina 

 gallica^ of Westerlund (Fauna Europ., 1876) again seems to 

 me the same variety. A very large number of conchologists 

 are still under the impression that every white-lipped nemoralis- 

 like snail is Helix /wrfensis, and I am sure a number of wrong 

 records have in this way crept into local lists. I did not find a 

 single specimen of true H. hortensis in the Pyrenees, and 

 although some writers state that it is found in Spain and 

 Portugal, I think it is highly probable, as indeed Westerlund 

 states, that it does not occur in those countries. In order to 

 make sure that the white-lipped specimens really were Helix 

 netnoralis, and not large H. /wrfensis, I dissected some of them, 

 and found that their anatomy agreed with the description of 

 the former. Even without looking at the dart, the long fla- 

 gellum, and the short and simple digital glands, distinguish this 

 species at once from H hortensis. — R. F. Scharff, Dublin,
