Schuchertella sp.

Fig. 22 .

Material.—A few mostly fragmented dorsal and ventral valves.

Remarks.—Although the studied material is invariably very fragmented the external ornamentation as well as dorsal cardinalia and asymmetrical ventral umbo lacking dental plates suggest that the specimens represent a species of

Schuchertella . Stratigraphic and geographic range.—The species is un−

common in samples GB and MH1.
