|Abstract||This paper deals with Foraminifera from 1) shallow water samples gathered by dr. P. WAGENAAR HUMMELINCK in the Florida Keys, the Cayman Islands, Jamaica, Puerto Rico, Virgin Islands, several Lesser Antillean islands from St. Martin as far as Tobago, Margarita, Bonaire, and Curaçao; 2) a sample collected by dr. P.J. BERMÚDEZ off La Habana, Cuba, at a depth of 2—5 fathoms; 3) samples gathered by dr. TH. MORTENSEN off St. Croix (= Santa Cruz), W. of Frederiksted, at about 17.5°N 64°W, depths 100, 150 and 500 fathoms; off Thatch Island, between St. Croix and St. John, depth 14—16 fathoms, and a sample taken between Tortola and Jost van Dyke, at a depth of about 20 fathoms.|
The species belonging to the samples W. of St. Croix of the families Valvulinidae, the Protoforaminata, the Biforaminata and the Deuteroforaminata including the Globigerinidae and other planktonic groups were already described in my paper on the “Foraminifera dentata; Foraminifera of Santa Cruz and Thatch-Island” (1956). Many other species, however, occurring in the MORTENSEN-samples have not yet been described and will be discussed here.
