REMARKS
Granulolabium plicatum has been discussed in depth and compared to similar species by Lozouet (1986) in an effort to clarify the differences between various potamidid and batillariid species. In Lozouet et al. (2001), an extensive list of the French literature is presented with the many different names attributed to G. plicatum, thus noting the confusion of the authors due to the morphological variability of the species.
The specimens from Felli show some residual colouration patterns that consists of darker and lighter spiral lines that coincide with the ornamentation (the spiral threads are darker and give a brighter colour under UV light).
Granulolabium species are able to withstand variations in salinity and they are known to characterize lagoonal or littoral environments (Latal et al. 2006; Esu & Girotti 2010). In the Paratethys (Korneuburg Basin, Austria) the Granulolabium - Agapilia biofacies represents slightly energetic conditions of an outer tidal flat (Zuschin et al. 2014).
