REMARKS

These shells are from Férussac’s collection. It is a little surprising to find types of Spix in the MNHN; perhaps they were donated to Férussac. The two shells appear to be different species on the basis of the difference in the size of the umbilicus. Further research is necessary, including assessment of type material in other collections, before either of these MNHN specimens could be designated as the lectotype. Authorship follows Cowie et al. (2004). Although Cowie &Thiengo (2003: 64) treated Helix lineata and Ampullaria figulina Spix in Wagner, 1827 as synonyms, these two species are now considered distinct from each other (Hayes 2009: 99); and although Thiengo’s paper ( Thiengo 1987: 563) was about Helix “ lineata ”, in fact it was dealing with Ampullaria figulina , as she now acknowledges (K. A. Hayes pers. comm., 14 June 2010).
