Extra details from original publication
Variation. - The degree of inflation of the last chamber, which in some specimens is slightly flattened out along the axis of growth, varies. (We consider the growth axis of spirally coiled forammifera to be the spiral line crossing the septa at midpoint perpendicularly to their surfaces.)
Comparison. - This species differs from Acarinina spiralis (Bolli) by its higher spire and the distinct spinosity of the wall on both sides of the test; from Acarinina aquiensis (Loeblich and Tappan) by the greater number of chambers in the umbilicus and the less coarse spinosity of the umbilical ends of the chambers.
