6o FLORIDA GEOLOGICAL SURVEY I3TH ANNUAL REPORT 



The only well from which specigiens of this genus were found 

 is that at Marathon on Key Vaca, where they occurred at a depth 

 of 852 feet. It would then seem that the well at this depth en- 

 tered or was in Upper Oligocene strata. 



This genus may prove to be a synonym of Miogypsina which 

 is also characteristic of the Upper Oligocene elsewhere. 



Gcntis Lepidocycliiia Gunibcl, 1868. 

 Lepidocyclina ocalana Cushman. 



This species which is typical of the Ocala limestone of Flor- 

 ida is found in recognizable form in the several wells : Jackson- 

 ville, first appearing at 510-550 feet, and fragments occur from 

 this point downward, probably all having their source at this 

 same depth as the well is not cased below this level. In the well 

 of L. E. Morrow at Sanford, Seminole County, at 113 feet, spec- 

 imens of L. ocalana occur in fragmentary form with other Ocala 

 species. At Cocoa, Brevard County, from the well of H. Brad- 

 ford, the species occurs in the only sample from 190 feet. In Ti- 

 ger Bay well at 360-400 feet abundant specimens of Lepidocyc- 

 lina, including "L. ocalana, were found. 



The Ocala limestone is therefore definitely placed by this and 

 associated species. 



Lepidocyclina floridaiia Cushman. 



This "species occurs with L. ocalana in the following wells: 

 L. E. Morrow. Sanford, Seminole County, at 113 feet; H. Brad- 

 ford, Cocoa. Brevard County, 190 feet, and at Tiger Bay, 360- 

 400 feet and at various points below, evidently originating from 

 this level. 



Lepidocyclina pscudocarinata Cushman. 



There are specimens of this species from two of the wells with 

 the preceding: Cocoa. 190 feet, and at Tiger Bay. 360-400 feet. 



Lepidocyclina pseudomarginata Cushman. 



Specimens which may be this species were obtained in the 

 Jacksonville Well at 510-550 feet, and a few fragments below. 

 More definite specimens were in the material from the well at 

 Tiger Bay. at 360-400 feet.
