Amauropsina arenularia (Vasseur, 1882) View in CoL
Fig. 10E, F View Fig .
Stratigraphic and geographic range.—Middle Eocene, Lutetian–Bartonian (PB, Loire−Atlantique).
Colour pattern description.—This species exhibits three levels of residual colouration. The background is dark and homogeneous. The apex is pale and there are three spiral rows of fluorescent patches. The patches are variable in shape and they are axially and spirally aligned ( Fig. 10E View Fig ). A specimen from Saffré (Loire−Atlantique) displays some sinuous axial segments ( Fig. 10F View Fig ). Depending on the part of the shell, there may be only axial elongated sinuous segments or alternating elongated and short straight segments ( Fig. 10F View Fig 2 View Fig ). In the latter case the two types of segments are sometimes connected ( Fig. 10F View Fig 3 View Fig ).
