Original Description

Translated from French : "Hedbergella sp. aff. infracretacea usually displays a more noticeable increase in the height of the spire, hence a slightly more important last chamber compared to the preceding ones. In profile view, the test seems to have a slightly less thick section. The ventral side is umbilicate as opposed to H. infracretacea which is devoid of umbilicus. In the evolved well-characterized forms, we can see a noticeable extension of the aperture towards the periphery, clearly reaching the dorsal edge: the coiling, however, remains asymmetrical, does not become planispiral. Occasionally a slight distortion of the trochospire has also been observed, the arrangement of the last chambers appearing to be less even than in H. infracretacea." [from Moullade 1966]
