Can anyone give me a good way to differentiate Neritina usnea [=reclivata],
N. clenchi, and N. virginea? Where does N. piratica fit in? The
characteristics in Abbott (1974) don't seem to hold up to inspection. Also,
does anyone know of a freshwater Neritina from Montserrat, or literature
that may help?
