1982 Warrenella euryglossa (Schnur) ; Drot 1982: 77, pl. 2: 16.

Material.—One nearly complete shell and one ventral valve from beds 29–30, three specimens from bed 43, one fragment of ventral valve from beds 50–51, and another fragment from bed 60 of Wietrznia Ie section, as well as one incomplete shell from bed 4, one complete shell from bed 14, and single fragment of ventral valve from bed 18 of Wietrznia Id−W section.

Remarks.—Specimens from the Wietrznia quarry are identical in external morphology with Warrenella (W.) euryglossa (Schnur, 1851) from Germany and Belgium.

Occurrence.— Warrenella (W.) euryglossa is known from the Frasnian of Germany and Belgium (Schnur 1853; Vandercammen 1957; Drot 1982). In Poland it was described from the Grained Limestone ( Polygnathus assymmetricus and probably Ancyrognathus triangularis zones) of the Dębnik anticline (southern Poland; Baliński 1979), the Kadzielnia Limestone of Kadzielnia quarry at Kielce (Biernat 1974). Racki (1993b) illustrated one specimen of W. cf. euryglossa (Schnur, 1851) from the Frasnian upper Sitkówka Beds of Sitkówka, Holy Cross Mountains. The specimens studied here were found in Wietrznia Id−W and Ie sections ( Palmatolepis transitans Zone ).
