An Additional Note on the Foraminiferal Genus Glaucoammina and Reophax Caribensis

Abstract

The foraminiferal genus Glaucoammina was described by Seiglie and Bermudez (1969), with Reophax trilateralis Cushman as type-species.  Three different forms of this variable species were included in the original description of the genus.  One of the forms consists of a triserial-uniserial form with an undetermined initial portion. The second form has an initial, slightly twisted, spiral form, that it is interpreted as a trend toward trochospiral.  The third form is the first objective of this note.  It consists of an initial enlarged portion followed by two to three uniserial chambers.
