Fig. 5H, I View Fig .
Stratigraphic and geographic range.—Early Miocene, Aquitanian (AB).
Colour pattern description.—These shells show two levels of residual colouration (apex absent): a dark and homogeneous background and opisthocline thin fluorescent stripes ( Fig. 5H, I View Fig ). These opisthocline stripes are very close to each other, parallel and present a regular distribution. Their thickness is constant on the shell and they are barely sinuous.
Comments.—All three specimens from Saint−Martin−d’Oney ( France, AB) display the characteristic morphology of Globularia (Cernina) compressa but the coloured pattern differs by the presence of opisthoclines, barely sinuous, thin stripes instead of axial zigzagging stripes ( Fig. 5F, G View Fig ). In our view, these differences do not result from intraspecific variability and justify these shells as belonging to a species other than G. (C.) compressa .
