Hi yourself, Rafael,
According to Abbott and Dance's "Compendium," (sorry, I do not have an
Oliva reference) there are at least two olives with the specific name of
acuminata. One is Ancilla acuminata (Sowerby, 1859) but it is from the
Red Sea area. The other is Agaronia acuminata (Lamarck, 1811) and it is
from west Africa. Maybe one of our olive folks can help more.
