Original Description

Test planispiral, though the early portion may be trochoid, evolute but not uncoiling, five or more chambers to the last coil; chambers inflated, very slightly appressed; sutures deep; wall finely perforate and quite smooth; aperture a thin lunate opening in the suture on the margin of the last chamber. 

EMENDED DESC [copied from Chronos database]- Test planispiral throughout, evolute but not uncoiling, 4.0 to 5.0 chambers in the last whorl; chambers inflated, very slightly appressed; sutures deep; wall finely perforate and quite smooth; aperture a thin to moderate lunate opening on the margin of the last chamber.

Diameter of type specimen, 0.6 mm.

Extra details from original publication
Occurrence: This species occurs as a very rare form throughout the Mendez, becomes quite abundant in the very base of the Velasco and dies out rapidly before extending any distance up into the Velasco.
This is a Cretaceous form which authors have invariably called G. aequilateralis Brady, but, unlike Brady's Recent form, it is not partially uncoiled and can always be easily differentiated from the Recent form on that basis. Cushman has made a new genus, Globigerinella, to include the two. I have felt that such is not advisable, at least for the Cretaceous form, which shows insensible variations from G. cretacea, with which it is much more closely related than to Brady's species.
