As Cox has pointed ont, Cardita and Venericardia are both based on Cardioid species 

 and not on forms with a Cardioid and Mytiloid faciès respectively, as stated by Dall. Fortunately, 

 as Stewart has rightly indicated, for the Mytiloid forms the names Arcinella Oken and Myti- 

 licardia Anton are available ; both of thèse hâve the Linnaean Chaîna calycîdata as the type, 

 and I sélect the older Arcinella as the subgeneric name for the Mytiloid forms.
