Problems of the geographic and stratigraphic distribution of American Middle Eocene larger Foraminifera

Larger Foraminifera from the middle Eocene of Florida and southern Georgia are discussed, including 2 new species, and their geographic and stratigraphic distribution, not only in the U. S., but also at selected localities in the Caribbean region, is analyzed. Several species not previously reported from the U. S. are discussed and illustrated. Analysis of the larger Foraminifera suggests that the Inglis limestone can not be separated from the underlying Avon Park Limestone and represents the upper part of the Avon Park Limestone and represents the upper part of the Avon Park Limestone. The Helicostegina gyralis zone (uppermost zone) of the Oldsmar Limestone (lower Eocene) is transferred to the basal Lake City Limestone (middle Eocene).
