Original Description

Test small, Hantkenina-like, almost planispiral to distinctly trochoidal, generally only last whorl visible. Chambers increasing in size as added, compressed in early portion of last volution, slightly to much inflated in the adult. Spines in axial position of the chambers, present throughout the last vi^horl or restricted to early chambers. Sutures straight, shallow, but clearly marked. Umbilicus developed in trochoidal species, probably with covering plate. Aperture unknown, in analogy to the related forms probably rounded and large, leading into the umbilicus. Wall thick and surface ornamented by minute spines and ridges, either irregularly distributed or arranged in rows radiating from a central point on the surface toward the apertural face (meridional pattern).

The subgenus is named after the late Mrs. Helen Jeanne Plummer who for the first time drew the attention of micropaleontologists to the ornate Upper Cretaceous Globigerinas

Extra details from original publication
Remarks.—This remarkable subgenus of Rugoglobigerina consists at present of one species split into 3 well-defined and easily distinguishable but closely related subspecies; P. hantkeninoides hantkeninoides (subgenerotype). P. hantkeninoides costata, and P. hantkeninoides inflata. Plummerella differs from the Tertiary genus Hantkenina Cushman 1924, to which it displays certain similarities, by the slightly to distinctly trochoidal adult stage and by the rugose surface showing a radiating structure at least in the more trochoidal representatives. From the Upper Cretaceous hantkeninoid genus, Schackoina Thalmann 1932, the new subgenus differs by the general form of the test, which in Schackoina is almost planispiral and involute in the adult, by the development of the spines, and by the ornamentation. (Cushman, 1946; Reichel, I947)

Occurrence.—Globotruncana mayaroensis zone, Guayaguayare beds, Maestrichtian, Upper Cretaceous, Trinidad, B. W. I.

Editors' Notes
The name Plummerella was a homonym of an insect Plummerella de Long 1942, so a new anme Plummerita was proposed in a separate Brönnimann (1952) publication
