Article: Wilkingia gen. nov. to replace Allorisma for a genus of Upper Palaeozoic lamellibranchs
R. B. Wilson
The Upper Palaeozoic lamellibranch genus Allorisma King 1844 is placed in the synonomy of Edmon¬dia de Koninck 1842, as the type species, Sanguinolaria sulcata Phillips 1836, is conspecific with Hiatella sulcata Fleming 1828, the latter species being an Edmondia. The name Allorisma King 1850, for a sinu-pallial form, is replaced by the new name Wilkingia. The type species Wilkingia [Venus} elliptica (Phillips) is described.
