Reophax caribensis, sp. nov., is described. It is provided with a friable test composed of poorly cemented grains, generally laminar, and lives in shallow waters. It is compared with similar species, especially with R. dentaliniformis Brady. Glaucoammina, gen. nov., is described and included in the family Lituolidae. The type species is Reophax trilateralis Cushman. This foraminifer is very variable in shape and lives on the outer submarine shelves of the Caribbean Sea. The test is composed of well cemented grains, mainly of glauconite, calcite, or dark minerals, or a combination of these.
