Een strandschelp van onze kust herontdekt: Spisula elliptica (Brown)

Spisula elliptica (Brown), by many authors regarded as a mere variety of Sp. solida (L.), is nevertheless a very distinct species. It is probably best characterized as a moderate-sized, equilateral Spisula of which the pallial impression and anterior muscular scar resemble those of Sp. solida (L.), the hinge that of Sp. subtruncata (Da C.), while the dorsal areas are not grooved. Of all authors only FORBES & HANLEY distinguish it from the other two species by mentioning this last point. Sp. elliptica occurs frequently all along the Dutch coast. Concluding from the material I have seen it ranges from Scandinavia and Iceland through the North Sea into the Channel.
