there is a description and account of the Atlantic Lottia alveus, designated

risk website
www.speciesatrisk.gc.ca
Tom Rice's recent checklist of NE Pacific (Oregonian Province) molluscs has
2 subspecies:
Altantic eelgrass limpet Lottia alveus alveus (Conrad, 1831)
Pacific eelgrass limpet Lottia alveus parallela (Dall, 1914).
