According to a fissurellid web site at:
vieoceane.free.fr/mollusques/Fissurellidae.htm the shells are very similar,
but the animals differ.  F. unguis is beige while F. sinensis is black.  I
found what looked like the same image used for both species, so who knows?

Dear All:

What is the difference between

Scutus unguis (Linnaeus, 1758),

and  S. sinensis (Blainville, 1825)?

Thanks,

Andrew
