18 EOCENE AND LOWER OLIGOCENE CORAL FAUNAS, 



Tlie tollowing- suli(li\'isions are recognized : 



3d. Frio clays. 



3c. Fayette sands. 



3/;. Yegua clays. 



3a. Marine beds. 



2. Liguitic beds. 



1. Wills Poiut or Basai ciays. 



1 is tlie same as the Midway beds of Alabama. 



2 contains fossils characteristic of tlie Liguitic (as defined by Harris 

 in his Arkansas report) of Alabama, i. e., Chickasawan. 



3a, 36, 3c, and Sd, all contain fossils belonging to tlie Lower Claiborne. 

 The Upper Claiborne is not represented. ^ The fossils, as acknowledged by 

 Mr. Dumble, were determined by Prof Harris. 



California. — Tlie Tejoii gToup lias been correlated with the Eocene Ijy 

 numerous investigators. A review of the literature on the subject to ISOI 

 has been published Ijy Prof W. 11 Clark in his l>ulletiii on tlie correlation 

 of the Eocene." 



In Science for August, 1893, page 97, Prof. G. D. Harris correlates the 

 fossils from Fort Tejon with the Lower Claiborne. Messrs. J. S. Diller and 

 T. W. Stanton make an additional contribution to the subject in Vol. V of 

 the Bulletin of the Geological Society of America, April, 1894, pages 437 

 and 438. Stanton has more recently made another contribution to the 

 subject,^ in which he recognizes an Upper and a Lower Tejon fauna, both 

 Eocene. He shows that the Martinez group of Gabb is a niixtureof Upper 

 Cretaceous and Eocene and determines to restrict the name Martinez to the 

 Eocene portion, which corresponds to the Lower Tejon. More stratigra})hic 

 work and more study of the faunas of the California Eocene are needed. 

 Dr. J. C. Merriam, of tlie University of California, is now engaged on such 

 a study, and has published one paper on the subject.* He restricts the name 

 Martinez to the Eocene })ortiou of Gabb's Martinez group, his conclusion 

 agreeing with that of Stanton.
