Emanuella sp.

Fig. 20A .

Material.—Two incomplete shells and 13 fragments from Wietrznia Ie section (beds 44–45, 48, 60, 65, 66, and 169).

Remarks.—This uncommon species is characterised by ventribiconvex shell which does not exceeds 16 mm in width and possesses subtrapezoidal outline. Both valves have very faint median furrow or sulcus, which on dorsal valve seems to be slightly stronger. Externally the species resembles somewhat Emanuella ? sp. from the Middle Devonian (Givetian) of Bathurst Island, Arctic Canada (Johnson and Pery 1976).

Occurrence.—This species was recovered from set C of Wietrznia Ie section representing Palmatolepis transitans conodont Zone.
