Material.—Two Pa elements from the upper part of the Ivanye Formation. Samples 2A/7 and 52/ 500 m.

Remarks.—Podolian specimens are closest in morphology to the holotype and other illustrated specimens from the type locality. They are of similar lenth and height, and have similar subtriangular outline of the basal cavity, and backwardly directed primary cusp with its tip broken of. Other denticles on the thin longitudinal ridge are lower and slightly flattened. One of the specimens bears small supplementary cusp on the outer side of that ridge.

Stratigraphic and geographic range.— Ancyrodelloides delta Zone in Hyde Parker Island and Delorme Formation, Lochkovian of northwestern Canada.
