Dear Ross et al.,
 
Lottia alveus (Conrad, 1831) may well be the limpet Ross has observed.  It
is presently considered extinct in the Atlantic Ocean.  If we are talking
about the same critter, we may have made an encouraging discovery and again
demonstrated the indispensability of amateur scientists in field biology.
