Nehdenites verneuilii (Münster, 1839) from the K. crepida Zone at Kadzielnia in the Holy Cross Mountains.

Diagnoza

Internal thickening of the conch parallel to aperture, well developed only ventrally; discoidal, relatively flat conch with gently rounded venter; suture almost straight ventrally.

Porównanie

Sobolew’s (1914) Oma-monomeroceras (Cheiloceras) discoidale , O. (Ch.) depressum, and O. (Ch.) lenticulare, from the Lower Łagów Beds probably also belong here, but pyritic specimens from Sieklucki’s brickpit attributed to the same species  may rather represent a species of Tornoceras.
