Remarks. - Distinguished by its small size and rapid trowth rate. The species identified by Bolli (1957, U. S. Nat. Mus., Bull., no. 215, p. 110, pl. 23, fig. 5a-c) as Globigerina bradyi Wiesner from the Cipero Marl of Trinidad is similar to Globigerinoides parva in its minute size and in having occasional supplementary aperture. Both Wiesner's and Bolli's figures of Globigerina bradyi illustrate a markedly more trochospiral test than in Globigerinoides parva, the chambers expanding much less rapidly with growth. The Recent Globigerinoides minuta Natland appears to be closely similar to Globigerinoides parva but it, too, has a slower rate of chamber expansion.
Globigerinoides parva is possibly the ancestor of a species very similar to Globigerinoides rubra d'Orbigny, present in lower Southland Series on the east coast of the North Island. The Southland species differs in being much larger htan parva, in having better developed supplementary apertures, and in having more coarsely reticulate surfaces."
