Collecting details:
From Oliver et al. (2020): "Type material: Possible syntypes as Fragments. Formerly attached to a beige card marked in pencil with “111. Physa alba”. TENBM 2001.129.05. (Fig. 24). Type locality: Towyn, North Wales, UK."; "We know from the literature that William Turton corresponded with Lyons but there seems to have been very little exchanging of specimens. Kennard (1944) considered one lot to have come from Turton because of the reference to “111” on Lyons' card which is a direct reference to Turton's Manual of 1831. If so Kennard considered these to be paratypes of Physa alba Turton and considered that they match the original figures. On the Smithsonian catalogue we could find no reference to this species in its original name or current name of Physa fontinalis with the type locality of Towyn, Wales. If Kennard is correct then these shells could act as syntypes but they are now in fragments and scarcely recognisable."
