NOTES ON THE TERTIARY GEOLOGY AND PALEONTOLOGY OF THE 

 SOUTHERN UNITED STATES. . 



BY PROF. ANQELO HEILPRIN. 



Eocene of Texas. In a limited collection of fossils from near 

 the northern border of San Augustine Co., Texas, transmitted to 

 me for examination hy the Texas State Geological and Scientific 

 Association, I have been able to determine the following species : 



Ostrea Alabamiensis. Cardita Blandingi (aUicosta). 



Ostrea sellaformis. Crassatella antestriata. 



Ostrea divaricata. Corbula Texana. 



Pecten Desliayesii. Buecitriton altile? {Texana). 



Anomia f Scalaria sp. indet. 



The horizon represented is evidently the " Claibornian," the 

 deposits probably occupying a position in the " Jacksonian " 

 area. 



The Nummulitic of Florida. Prof. G. A. Wetherby, of Cin- 

 cinnati, has furnished me with a number of rock fragments ob- 

 tained at a locality some six miles southwest of Gainesville, Fla. 

 They are interesting as containing, in addition to one or more 

 species of Orbitoides, several nearly perfect individuals of Num- 

 mulites Floridanus Heilprin, which, therefore, represent the most 

 northern locality in the State where the members of this group 

 of Foraminifera have thus far been found. They lend further 

 confirmation to the views already advanced by the writer as to 

 the broad extent of the southern Nummulitic formation, and to 

 the relative antiquity of the Floridan peninsula. One consider- 

 able fragment of a Heterostegina is also represented in the rock. 



Since the receipt of Prof. Wetherby 's specimens I have been 

 favored, through Mr. Joseph Willcox, of this cit}'', with other 

 fragments from approximately the same locality, Arredonda, 

 Alachua Co., which also contain Nummulites Floridanus, Orbi- 

 loides, and Operculina rotella ( 0. complanata ?). 



Eocene of Kentucky. Mr. R. H. Loughridge has kindly for- 

 warded to me for determination a number of fossils collected by 

 the Geological Survey of Kentucky, from the immediate neigh- 

 borhood of Paducah. They are mainly in the form of casts in a 

 highly ferruginous and fairly micaceous yellow-white sandstone,
