Bolli (1957):
The Trinidad specimens here described as Globigerina bradyi seemingly agree well in size and general shape with Brady's figures of Globigerina sp., which later were named by Wiesner as G. bradyi. Occasionally, specimens are seen that have one or several secondary sutural apertures on the last chamber. They should probably be placed in Globigerinoides minuta Natland. The two species seem to be synonymous, with the exception that G. minuta has sutural apertures on the final chamber, which might be a gerontic stage. More detailed work will be required to establish possible relationships between Globigerina bradyi and Globigerinoides minuta on the one hand and Globigerina juvenilis and G. bradyi on the other. In this connection, possible relationships between G. juvenilis and Globigerinita naparimaensis Bronnimann and between Globigerinoides minuta and Globigerinoita morugaensis Bronnimann should also be studied. |
