Original Description

Test free, small, trochospiral, globose, of 2 1/2 to 3 whorls, outline quadrate, lobate, periphery broadly rounded, spiral side convex, spire low to high, sharp, in center of test. Chambers inflated, quadrate in spiral view, oval to quadrate in umbilical view, circular to slightly rectangular in edge view, increasing rapidly in size, 4 in last whorl. Sutures radial, depressed. Wall relatively thin, finely hispid. Aperture umbilical, a low oval, about twice as wide as high to nearly circular, bordered by a small raised commonly upturned lip.

Size:

Greatest diameter of holotype .204 mm; greatest thickness .153 mm.

Etymology:

This new species is named in honor of M. N. Bramlette, Scripps Institution of Oceanography, in recognition of his studies of the Miocene stratigraphy and micropaleontology in California.

Extra details from original publication

Globigerina bramlettei is similar to the warm-water variety of Globigerina pachyderma of Parker (1962, p. 224). It differs primarily in its more lobate outline, larger size, and thinner test walls. The aperture in G. bramlettei is consistently umbilical in position whereas the apertures of typical and warm-water G. pachyderma may tend to be extraumbilical. The surface texture of G. bramlettei is finely hispid; that of most specimens of G. pachyderma is peculiarly pitted and the wall is much thicker.
