Cardium angulatum Lamarck, 1819: a misinterpreted senior synonym of Cardium alternatum Sowerby, 1840

Abstract

Examination of the type material of Cardium angulatum Lamarck 1819, demonstrates that the name is not a synonym of C. rugosum as it has often been accepted. Instead it proves that C. angulatum is the valid name for the Indo Pacific species known as C. alternatum Sowerby, 1840. Because Sowerby’s name is not that of a common and/ or economically important species, it is proposed to adopt Lamarck’s name.
