Original Description
The calcareous hyaline test is initially coiled in a low trocho¬ spiral, later becoming a high trochospiral with an accompanying shift in the axis of coiling. The early chambers are globular, inflated, and globigerine-like. Later chambers are axially (vertically) elongated, but they are dorsally flattened and exhibit a keeled, imperforate, peripheral band. The early chambers are smooth to irregularly hispid. Later chambers exhibit pustules and traces of costellae. The aperture is rounded, interiomarginal, and opens into a relatively small but deep umbilicus. Short apertural flaps extend into the umbilicus but do not form a cover-plate.

Etymology: This genus is named for Walter H. Bücher.

Extra details from original publication
Remarks: Bucherina, n. gen., resembles Globotruncana and Rugotruncana, n. gen., but it differs from both in lacking an umbilical cover-plate and in exhibiting a shift in the axis of coiling. It is also similar to its forerunner, Kuglerina, n. gen., but the latter has no imperforate, peripheral band.
Bucherina, n. gen., is monotypic; however, Globigerina mckannai White from the Velasco [ Tamesi] shale of México may possibly belong to this genus.

Age: Maastrichtian.
