This specics differs from H. hiSJ)icla, in being thinncr and more globular in form, aud in thc umbilicus being smaller. It will be known from the }f. gnmulata, by being wrinkle<l, m- stead of having granulatious. Inhabits woody situations. l\fr. Alder, who firsl introduced this shcll on thc faith of Baron de Férussac, gil'es no locality for it. i\ir. Thompson gives it as an Irish specimen, from Lagan, near Ilelfast, but considers it as mcrcly a variety of /l. hi.~pida. 22. I·IELJX msPJDA, pi.
