In a note following the original description, the author makes .
the following remarks : —" .... The primary teeth are somewhat
peculiar, and have a tendency to shelve outwards ; the hinder
and central ones are not strictly bifld, but exhibit a kind of
shallow sublateral grooving; the front one in the right valve
is very short, and simply pyramidal. The beaks are probably
acute when young; the surface below the epidermis is reddish
purple."
