One specimen, shell only. This species belongs to the same group of Solenidse as the Mediterranean Solen strigilatus of Linne, which formed the type of Section B of Blainville's genus Solecurtus (1824)*. His section A had for type Solen radiatus Linn., which belongs to the genus Siliqua Miihlfeld (1811) t- It therefore seems advisable to place the present species under the genus Macha, which was described by Oken in 1835 J for the reception of Solen strigilatus. Her-mannsen § quotes Macha as described by Oken in 1815; but I have searched in vain in the ‘ Lehrbuch ' || for any mention of this genus, which should therefore date from 1835.-E. A. S. * Diet. Sci.
