Diagnosis Test small, robust fusiform, earliest three to four whorls discoidal with short axis of coiling, later whorls with changed and rapidly lengthening axis of coiling; septa plane, unfluted; wall with tectum and diaphanotheca, tectoria not apparent, tunnel widening rapidly, bordered by massive, asymmetrical chomata that extend nearly to the poles. U. Permian (Darvasian to Murgabian); S. China; Japan; Korea; USSR; Yugoslavia; Sicily; Greece; Turkey; Afghanistan; Algeria.
