In a note following tbe original description, tlie 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 bifid, but exhibit a kind of 

 shallow sublateral grooving; the front one in the right valve 

 is very short, and simply pyramidal. Tlie beaks are probably 

 acute Avhen young ; the surface below the epidermis is reddish 

 purple."
