FORAMINIFERA FROM DEEP WELLS 53

 Piuvintilina ? sp.
 Plate 2, figures 7 a, b.
 Associated with the conical Orbitolinia in three wells there is a species which may be assigned to Pulvinulina. It is of small size, the dorsal side strongly convex, the ventral side less so, and when worn shows a peculiar series of openings about the umbilical area.
 It is found in material from the following: New City Well at Jacksonville, at 820-845 feet; Ponce de Leon Well at St. Augustine at 785 feet; and City Well at Apopka, Orange County, at 115 feet.
 This is another one, of the species which 'is characteristic of the fauna of the upper Orbitolina Zone.

 Genus Gypsina Carter, 1877.

 Large specimens which may be referred to this species are from the well at Marathon, on Key Vaca, at 598 feet. These are similar to those which were found at Anguilla, Leeward Islands, where, as in the Marathon Well, they occurred in company with Orbitolites.
 Smaller specimens of the form which is characteristic of the Ocala limestone were found in the Jacksonville Well, at 680-702 feet, and occasionally below. These all probably came from the level of 510-5o feet where the Ocala evidently is entered and from which point downward there is no casing. Similar specimens also occur in the well of the Bonheur Development Company at Burns, Wakulla County, at a depth of 50 feet, and in the well of the Compagnie Generale des Phos. de la Floride, at Anthony, Marion County, also at 5o feet. This latter well is known to start in the Ocala limestone. Other species from Burns confirm the occurrence of the Ocala at 50 feet as indicated by the Gypsina.
