Hi Bill,
I think the recent photo by Marli is H. vesicula. This is the only species I have seen in B.C. although I have seen the others further to the south. It is extremely common in muddy bays in and around eelgrass beds. H. vesicula has a very small indent in the mid-posterior line of the cephalic shield, H. virescens has none and the shell is greenish, H. callidegenita has a deeply bifurcate posterior shield. They are all very different internally.
