54 FLORIDA GEOLOGICAL SURVEY-13TH ANNUAL REPORT

 The species of Gypsina referred to G. globulus in the Coastal Plain and.West Indian region need careful study to discriminate between the different forms found in different horizons.

 Specimens of the forms figured from the Miocene of the Coastal Plain were found in material from the well at Fort Myers, at a depth of 300 feet, and the well at Okeechobee, at a depth of 41-56 feet.
 This has been recorded from the Miocene of Florida in the Choctawhatchee Marl of Coes Mill, and Jackson Bluff, as well as from the Miocene and Pliocene of several other states.

 Rotalia armata d'Orbignv.
 Rotalia armata d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 273, No. 22; Models, 1826, No. 70.
 Rotalina armnata Terquemi, Mem. Soc. Geol. France, ser. 3, vol. 2, Mem. III, 1882, p. 67, pl. 5 (13), figs. 14, 15.
 In a single well, that of the Bonheur Development Company at Burns, Wakulla County, numerous specimens occur at I8o feet, and scattered below as casts which are very close to this species of d'Orbigny, which seems characteristic of the Eocene of the Paris Basin at some horizons.
 The specimens are in such numbers in this well that it seems as though they may be later discovered somewhere in surface deposits of this same age in the Gulf region.
 Occurring as it does below the horizon marked by characteristic species of the Ocala, it should be looked for elsewhere in a similar stratigraphical position.
