Naticopsis ? sp. 3

(Fig. 20 G–I)

Material. One specimen: ESKU-19- LP 32.

Dimensions (mm): ESKU-19- LP 32: height = 5.3; width = 7.8; apical angle = 108 º.

Description. Shell flatly turbiniform to naticiform with about three whorls (apex missing); spire elevated; rate of whorl expansion rapidly increasing; body-whorl broad, approximately 70% of the entire height; whorls rounded, strongly convex, with undulating, irregular axial ribs; base rounded; aperture unknown.

Remarks. The undulating, irregular axial ribs on the whorl surface and the broader body-whorl distinguish Naticopsis sp. 3 from the others present in this fauna. It might represent a new species, but the poor preservation prevents a further taxonomic assignment.
