FORAMINIFERA FROM DEEP WELLS 55 



Rotalia sp. 



In the well at Marathon, on Key Vaca, a sj^ecies of Rotalia oc- 

 curs in some numbers at 1,273 ^^^^- ^^ is unlike those found else- 

 where in the well samples, but is not well preserved as to details 

 of the surface characters. 



Rotalia ? sp. ' 



In two wells, the New City Well at Jacksonville, at a depth 

 of 680-702 feet, and that of J. Wiggins at Eustis, Lake County, 

 at a depth of 138 feet, there is a large rotaliform species which 

 seems more or less involute on both faces. The sutures are marked 

 by raised lines. The peripheral margin is angled, the dorsal surface 

 just within the periphery slightly concave.

In two wells, specimens evidently this species were obtained. 

 These are 87-94 feet in the well at Okeechobee, and 180 feet in the 

 well at Marathon on Key Vaca. 



This species is known from the Miocene of the Choctawhatchee 

 Marl of Florida, and from the Miocene of Maryland, Virginia, 

 and South Carolina. It occurs also in the Gatun formation of the 

 Panama Canal Zone.
