I hâve adopted this subgenus as restricted by Lamy and recently so well defined by Cox, 

 and include in its synonymy Scapharca Gray and Anomalocardia Adams (nec Schumacher, 

 1817 non the pre-LiNNEAN one of Klein 1753). The génotype is A. {A:) antiquata Linn. ^).

i) I hâve since had the occasion to refer to Stewart's valuable work — Spécial Publication Acad. Nat. Sci. Philadelphia, N" 3, 

 p. 83 (1930) — where he has accepted Schumacher's désignation of Arca antiquata (Linn.) as the type of Arca s. s. If this view is 

 accepted, as I believe it to be correct, the subgeneric name A?iadara Gray, as adopted in this report, will become an exact synonym of^r^iZ s.s.
