Extra details from original publication
Occurrence.- Rare in the middle bed at the D. M. S. & B. Quarry. Not presen in the Timms Point Pliocene material we have examined. Rare to common in well samples from the Saugus and rare in those from the Upper Pico of the Los Angeles Basin. Numerous authors have figured it from Recent material. This species differs from Rotalina crassa d'Orbigny (Mem. Soc. Geol. France, vol. 4, 1840, p. 32, pl. 3, figs. 7, 8) from the Upper Cretaceous of France, by its more inflated chambers which are fewer to a coil; its deeper sutures; its more angled periphery and by the character of the aperture.
