54 FLORIDA GEOLOGICAL SURVEY I3TH 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. 



Genus Roialia Lamarck, 1804. 

 Rotalia beccarii (^Linnaeus). 



Nautilus beccarii Linnaeus, Syst. Nat., 12th Ed., 1767, p. 1162.

Specimens of the forms figured from the Miocene of the Coast- 

 al 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 ]\Iarl of Coes Mill, and Jackson Bluff, as well as 

 from the Miocene and Pliocene of several other states. 



• ^ Rotalia armafa d'Orbigny. 



Rotalia armata d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 273, No. 22; 

 Modeles, 1826, No. 70. 



Rotalina armata Terquem, Mem. Soc. Geol. France, ser. 3, vol. 2, Mem. 

 Ill, 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 180 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 character- 

 istic species of the Ocala, it should be looked for elsewhere in a 

 similar stratigraphical position.
