FORAMINIFERA FROM DEEP WELLS 59 



the well at Panama City; especially at 150 feet and at lower depths 

 probably derived from this level in the well of the Bonheur De- 

 velopment Company at Burns, Wakulla County; at 550 feet and 

 below in the New City Well at Jacksonville, Duval County; abun- 

 dant at 50 feet and scattering below in the well of the Compagnie 

 Generale des Phos. de la Floride., at Anthony, Marion County; in 

 the upper portions, probably above 138 feet in the well of J. Wig- 

 gins at Eustis, Lake County; at 410 feet especially and scattered 

 below in Well No. 3 of the Palmetto Phosphate Company near 

 Pit No. I, about 2 3-4 miles northwest of Tiger Bay. 



Genus Opcrculiiia d'Orhig,ny, 1826. 

 Operculina sp. 



The only specimen that may be referred to this genus is from 

 the well at Marathon on Key Vaca, coming from a depth of 589 

 feet, but this is broken and not specifically identifiable. Where 

 Operculina was recorded in the earlier paper on the well samples, 

 (i2th Annual Report, Florida Geological Survey, 1919, pp. 77-103) 

 a closer study has shown them to be Hcterostegina ocalana. 



Genus Heterostegina d'Orbigny, 1826. 

 Heterostegina ocalana Cushman. 



Occurring with the various species of Lepidocyclina and also 

 characteristic of the Ocala limestone this species confirms the age 

 of the Ocala in the well borings. It occurred in recognizable 

 form as follows : well of L. E. Morrow, Sanford, Seminole 

 County, 113, feet; well of H. Bradford, Cocoa, Brevard County, 

 190 feet; and Tiger Bay at a depth of 360-400 feet. It is char- 

 acteristic of the Ocala, especially in north-central Florida arid 

 is also found in the Ocala of Georgia. 



Genus Heterosteginoides Cushman, 1918. 



H eterosteginoides cf. panamensis Cushman. 



Heterosteginoides panamensis Cushman, Bull. 103, U. S. Nat. Mus., 1918. 

 p. 97. pi. 43, figs. 1-8. 



This species is common in the Culebra formation of the Pan- 

 ama Canal Zone, and a related species has been described from 

 Crocus Bay. Anguilla, Leeward Islands.
