Diamcter upwards of thrcc-eighlhs of an inch; lenglh not. quite so much. This spccics is ncarly allicd to H. hispida, but somcwhat larger, with a wider nmbilicns, the hairs considcrably more dis- tan!, ancl is gcnerally more convex. The 11. concinna is widely sprcad all over England and Ireland. Its habitat is in dry situations, under stoncs and among nelllcs. 2-1. HELIX DEPILATA, pi. XVIII, f. 47, 48.
