The Gastropod Thais haemastoma in Georgia: T. h. floridana or T. h. canaliculata?

Document Type

Short Communication

Abstract

In the southeastern United States, the snail Thais haemastoma has traditionally been subdivided into two subspecies according to the snail‘s locale, size of shell, number and size of spines, and depth of suture. Only Thais haemastoma floridana is supposed to occur in Georgia; since Thais haemastoma canaliculata is supposedly restricted to the Gulf of Mexico region. In Georgia, specimens fitting the description of both subspecies are common. The author concurs with the conclusions of Butler (1953) and Gunter (1979) in that the subspecies nomenclature is invalid and that they are merely ecological variants.
