Subgenus Deshayesia Raulin, 1844

Type species: Deshayesia parisiensis Raulin, 1844 , Morigny, Rupelian (Stampian).

Globularia (Deshayesia) parisiensis (Raulin, 1844) Fig. 5J .

Stratigraphic and geographic range.—Early Oligocene, Rupelian ( PB).

Colour pattern description.—The shells show three levels of residual colouration (apex absent). The background is heterogeneous with three broad spiral slightly fluorescent stripes and there are some axial and fluorescent thin zigzagging stripes. The spiral stripes are located (i) on the subsutural part, (ii) near the base, and (iii) on the median part. The transition between the two levels of colouration of the background is diffuse. The thin axial zigzagging stripes are superimposed on the background ( Fig. 5J 1 , J 3 ). The thin axial stripes connect each other in several points and their distribution on the shell is regular. The zigzags present variable amplitude.
