Original Description

Test small, about twice as long as broad, gradually broadening from the subacute initial end to the point of greatest breadth, which is slightly above the middle, after which the sides become parallel; periphery slightly rounded, in transverse section some what rectangular; biserial throughout; chambers broader than high, indistinct; sutures indistinct, slightly depressed; wall smooth; aperture rounded, at the end of a short but distinct neck, with a weakly-developed lip. 

Size:
Length 0.3 mm; breadth 0.2 mm."

Extra details from original publication
This species was found in samples no. 21, 8 and 9, Nekhl, and no. 835, Giddi. It is a distinctive species, which is here assigned to the genus Zeauvigerina, although this genus was recently suppressed by Loeblich ( 1951) after a study of the genotype of Eouvigerina. Zeauvigerina deserves to be re-established, to include forms that are completely biserial and with the aperture on a neck. The discovery of the present species in the material examined extends the range of this genus into the Cretaceous.
