AbstractIn spite of the generally poor preservation of the specimens, it could be observed that in many specimens the large, often somewhat trochoid spiral out of PA-I, surrounding I and II, passes the small spiral out of PA-II without forming a closing chamber. In several specimens the vertical section shows that the embryonic-nepionic apparatus forms an angle with the equatorial plane. This makes it difficult to distinguish in a horizontal thin section a spiral chamber from an equatorial or lateral chamber. The sample used contained numerous microspheric specimens, which are markedly different from the megalospheric specimens both externally and internally. The difference between the subgenera Miogypsina and Miolepidocyclina is discussed.
