Description of two new marine shells dredged off Three Hut Point, D'entrecasteaux Channel, Tasmania

Description of two new marine shells - Delphinula johnstoni, n.s.- This shell is closely allied to D. tetragonostoma, Tenison- Woods (fossil sp.), and forms an interesting link with the marine life of the tertiary period and Leda lefroyi, n.s. This interesting shell is very distinct from any known species. It approaches the Patagonian Leda (L. patagonica D'Orb.) in form, but it is much smaller and is sculptured differently.
