Lyell says that Helix hortensis & nemoralis differ only in hortensis having white lip, for in other respects both vary with each other. Deshayes though same (see Forbes & Harley) — yet H. hortensis ranges further than nemoralis, & alone is found in Canada.— good case of doubt as commonest species & generally found together.— (Q)

[Quoted in Natural selection, (F1583) p. 113.]

Helix aspersa in S of France sports much & & a var. admitted by everyone as var is found in Sicily, but in addition is thought by some to be identical with the yellow varying H. nessalina of Sicily. This very striking became H. aspersa is so excessively uniform in most parts — Lyell remarked to me that it so might be in time: H aspersa with fd in Loess.— Succinea oblonga in Loess— very rare in England, in Pevensey, & not living — Isle of Wight, but fossil in Isle of Wight. —
