Cerithiopsis undetermined

Cerithiopsis indet. (Fig. 6E 1-E 3, F 1-F 3, G 1-G 3) MATERIAL AND DIMENSIONS. — Height 4.6 mm (incomplete), width 1.7 mm. — RGM.1365212 (1), leg. ACJ; RGM.1365310 (9), leg. ACJ; RGM.1365307 (1), leg. ACJ; RGM.1365306 (1), leg. ACJ; RGM.1365308 (2), leg. ACJ; RGM.1364977 (23), leg. ACJ; RGM.1365309 (1), leg. ACJ; RGM.1365311 (1), leg. ACJ; RGM. 1365313 (1) leg. unknown, RGM.1365078 (c. 135) leg AWJ, RGM.961903 (26), leg. AWJ; RGM.961908 (7), leg. unknown. DISTRIBUTION. — Lower Pleistocene: Atlantic, Selsoif, NW France (this paper). REMARKS Cerithiopsidae can only be reliably identified using protoconch characteristics. The absence of protoconch in all our specimens make it impossible to make a definitive identification. The illustrated specimens show some of the morphological variability encountered in the Cerithiopsis specimens at hand.
