Microcochlis n.gen.

Type species. Microcochlis parva n.sp.

Definition. Minute, turbiniform with shallow sutures, somewhat flat whorl profile, and narrow umbilicus; ornament of rather widely spaced prosocline collabral cords with weak spiral cords.

Geological age. Late Tournaisian.

Remarks. Microcochlis n.gen. differs from Eucochlis Knight and Kyndalynia n.gen. in having a flat whorl profile and coarser collabral cords modified with weaker spiral cords. It has a narrow umbilicus as seen in some species of Eucochlis, but differs from Kyndalynia in that the latter has a round whorl profile and a wide umbilicus.
