Extra details from original publication
Comments: Globigerinoides kennetti differs from Globigerinoides bollii Blow in typically possessing 3 to 3½ instead of 4 chambers in the last whorl, less embracing chambers, and a more subquadrate outline. Globigerinoides kennetti is distinguished from Globigerinoides ruber (d 'Orbigny) by a more heavily encrusted test. more embracing chambers. and variable supplementary apertures which, if present, are very small compared to the large supplementary apertures commonly found in G. ruber. A heavily encrusted test and a constricted primary aperture distinguish G. kennetti from Globigerinoides subquadratus Bronnimann. In addition. these 2 species do not have overlapping ranges.
Globigerinoides kennetti appears to have evolved from the Globigerina woodi group. and specimens judged intermediate between G. woodi Jenkins and Globigerinoides kennetti are occasionally encountered (pl. 1. figs. 11-1 2) . Typical G. kennetti is easily distinguished from Globigerina woodi by having 3 chambers in the last whorl, a subquadrate outline, commonly developed supplementary apertures. and usually a more prominently encrusted test.
