Extra details from original publication
Remarks: Globotruncana wilsoni, new species, differs from Globotruncana lapparenti bulloides Vogler in having only 4 chambers in the last whorl. The general outline of the equatorial periphery is more oval compared with the more circular form of bulloides, and the 2 keels are
more closely spaced and often reduce to one in the last chamber. Globotruncana wilsoni, new species, occurs in the Globotruncana concavata zone, before the advent of typical Globotruncana lapparenti bulloides. Transitional forms between Globotruncana wilsoni, new species, and Globotruncana fornicata Plummer have been observed.
