Original Description
Like aragonensis Nuttall but has only 4-5 chambers per whorl, a sharp keel, and a practically flat top.

Extra details from original publication
From Hornibrook 1958:

Finlay described this species as follows: " ... like aragonensis...but has only four or five chambers per whorl, a sharp keel, and a practically flat top."" No figure was given. The type locality is F5570, chalk marls below Amuri Stone, Hurunui River, one-half mile southwest of Trig. B (Lowry Peaks S. D.); Heretaungan stage (Lower Eocene). The specimens later figured by Finlay as Globorotalia crater (F567J, S68/20I, base of sandy mar! separating greensands from the chalk marls, 30 chains northwest of the Middle Waipara gorge, left bank) are from older beds that are of Waipawan or Mangaorapan age (Paleocene-Lower Eocene), and are not typical. They differ from Globorolalia crater sensu stricto in being smaller, without a wide-open umbilical depression, and in having a more prominent flange. Globorotalia crater, with its wide, deep umbilicus, squarish shape, and prominent ornamented dorsal sutures, is almost identical with the species figured as Globorotalia velascoensis Cushman by Hamilton (1953, pl. 30, figs. 16-18) from mid-Pacific seamounts."

Editors' Notes
The holotype was first illustrated by Hornibrook 1958, from material deposited by Finlay in the New Zealand Geological Survey collections. Hornibrook (1958) does not make clear whether he selected the holotype or it was indicated on the material deposited.
