Notes on the Fauna of the Chipola Formation -XXXIII Variations on a Theme - the Color Pattern in Smaragdia Chipolana (Gastropoda: Neritidae)

Abstract

The small neritid gastropod originally named Neritina chipolana (Dall, 1892, p. 422, pl. 23, fig. 19) is a common element in the fauna of the Chipola Formation. Although confined to the Chipola Formation it is widespread there, occurring at almost every locality but most abundantly in the lower beds along Tenmile Creek.
