Material.—16 Pa elements from the Dzvenyhorod, Khudykivtsi and Tseliyiv Formations. Sections and samples 14/ 1,3 m, 14D/1, 37/1, 1a, 37A/2, 37B/1.

Remarks.— Zieglerodina planilingua is distinguished from Z. remscheidensis by contrasting lower and raised posterior section of the blade with low slightly backwardly inclined denticles. Just behind the cusp these denticles are very small but became higher towards the posterior end of the blade.

Stratigraphic and geographic range.—Uppermost part of “ Ozarkodina ” eosteinhornensis Zone and lower part of Caudicriodus hesperius Zone in Podolia. Uppermost Pridoli to middle Lochkovian in central Nevada and Spanish Pyrenees, New South Wales ( Australia), Frame Formation in Texas.
