Hofker (1968 : 18) has shown that this trend occurs only in some gerontic microspheric forms, the megalospheric forms having simple apertures. The present material, with the exception of one 'cribrolinoid' specimen, has relatively simple apertures with single or bifid teeth. 15a. 17a Figs 15a-17b Quinqueloculina curta Cushman.

Distribution. Fossil: Late Tertiary (?

Recent: This species occurs widely at the present day in the west Pacific Islands from Japan to New Guinea.
