In the Family Angariidae we regard an enormous variability of nearly all species identified and described up to now. That leads to a lot of doubtful or wrong determinations and designations both in collections and on the shell market.
In view of this fact here anew will be made efford of an overview of the determinations as they are actually valid. For this purpose in this blog I will establish a glossary for describing details of the Angaria shell structure, specially those details which are important for the differential determination of species, subspecies and variant forms.
Text and picture material are in statu nascendi and will be successively added and accumulated.
