Description
An enlargement of the wall structure illustrated by Rauzer-Chernousova & Fursenko (1959, *1509, pl. 7, fig 15B), shows it to be rather typical of the Fusulininae group of forms that occur from the upper part of the Myachkovo Horizon to the bottom of the Upper Carboniferous, southern Urals, Russian Platform. No axial fillings are visible in the axial section (loc. cit., pl. 7, fig. 15A) and the septa are intensely fluted. The details by which this genus differs from Quasifustulina Chen, 1934, are not understood by me.
