Specimens from U. S. G. S. station 7689 

 (Tivola tongue of Ocala limestone, Tivola, Ga. ; 

 C. W. Cooke, collector) are evidently this 

 species with the variety suhdecorata, described 

 below. 



Both the species and its variety seem to be 

 highly characteristic of the Ocala limestone in 

 west-central Florida and are very abundant. 

 The development and subsequent reduction of 

 pillars seem to indicate senescent characters 

 even in the upper Eocene. The species seems 

 to be to a great extent replaced in Georgia and 

 elsewhere by the very much larger L. geor- 

 giana, unless it occurs there at different hori- 

 zons.

Plate XXVIII, figure 5. 



Variety differing from the typical species in 

 its usually thinner, more distinctly umbonate 

 test, and sm-f ace with prominent papiUae, even 

 near the periphery. 



In most material in which typical L. ocalana 

 occurs this variety also is present. In size and 

 general characters the two are similar, but the 

 variety is distinctly papillate throughout, a 

 character which may be accompanied by the 

 thuxner and more umbonate test. As a rule 

 this is not as common as the typical form, but 

 in one or two lots of material it seems to be 

 fairly common while the typical form is rare or 

 absent. 



It was noted in material from the following 

 stations:
