Original description Description. Shell of moderate to large size, inflated fusiform to subcylindrical, with straight axis and sharply to bluntly rounded poles. Mature specimens usually possess 6.5 to 8 whorls and are bilaterally symmetrical at all stages of growth. Proloculus small. First 2 to 3.5 whorls constitute tightly coiled juvenanum, which is terminated by abrupt expansion into loosely coiled adult stage. Spirotheca composed of tectum and keriotheca. Septa strongly but somewhat irregularly fluted throughout shell. Septal folds high, extending to top septa. Low cuniculi developed from four or five volutions. Phrenothecae weak or absent. Weak axial filling present only in juvenarium. Tunnel low and narrow. Small chomata sometimes present on the proloculus.
Discussion. Iranella. n. gen is very similar to Paraschwagerina Dunbar et Skinner in many aspects, but the latter has not cuniculi. Besides, the age of true Paraschwagerina is older (Asselian and Sakmarian). In addition to the species described in this article, the genus includes a specimen derived from the Bolorian deposits of Japan and referred by Morikawa & Isomi (1961) to the American species Paraschwagerina gigantea (White). All species of the genus Iranella described below are connected by transitional forms with Iranella bella n. sp., which is gradually changed to Chalaroschwagerina (Cuniculina) vulgarisiformis (Morikawa) (Fig. 4).
Distribution and age. Iran, Darvaz, Japan (?); Early Permian (Cisuralian), Bolorian.
