Genus Globularia Swainson, 1840

Type species: Globularia sigaretina ( Lamarck,1804) , Grignon, Lutetian.

Description.—This genus is here considered to comprise three subgenera ( Globularia , Deshayesia , and Cernina ) with 20 species (16 Palaeogene species, 3 Neogene and one extant; SOM 1). The taxa Globularia , Cernina , and Deshayesia have not always been regarded as congeneric ( Wrigley 1946). Nevertheless, the very similar residual colour patterns of 11 of the 15 studied species (zigzagging axial fluorescent stripes; SOM 2; Fig. 4 , 5 ) strengthens the initial impression based on the shell morphology (wide aperture with prosocline outer lip, low spire and expanded sheath delineated by a rim) that they are closely related ( Cossmann and Peyrot 1919; Wenz 1941). Thus, thanks to the additional character, all these species are, here, no longer considered to belong to distinct genera but are placed within the genus Globularia (senior synonym).
