Siphonaria funiculata Reeve (Siphonariidae, Pulmonata): A Redescription Making S. Virgulata Hedley A Geographical Variant of S. Funiculata.

Summary

Based upon the examination of anatomical features and shell morphology Siphonaria funiculata Reeve, 1856 and S. virgulata Hedley, 1915 from southeastern Australia are considered to be synonymous, the former having systematic priority. Characters previously considered of specific value, particularly shell and radular, are shown to be widely variable. Investigation of geographical shell variation indicates that the nominal species S. virgulata is a clinal variant of S. funiculata at the northern end of its geographical range.
