Choristella
Choristella sp.—new record Distribution. A single empty, somewhat damaged shell has been dredged on the Agulhas Bank (off Cape St Francis, E. Cape), 210 m. Notes. The fragile, smooth, globose, white shell, with a deeply channelled suture and distinct umbilical carina indicate that this material is r...
