306 T. H. Aldrich — Tertiary of Alabama. 



Section half a mile north of St. Stephens. 



No. 6. White limestone, highly charged with Orbitoides 



Mantelli. 40 feet. 



No. 5. Hard ledge limestone containing spines of a species 



of Cidaris . . 2 feet. 



No. 4. White limestone containing P. perplanus Mort., 



etc., no Orbitoides found, . 50 feet. 



No. 3. Scutella bed. Yellow sand indurated in places,.. 2 feet. 

 Also containing Osteodes — sp. ? 



No. 2. Claiborne sand, 15 feet thick in places measured, 



containing the well known Claiborne fossils 15 feet. 



The sand is a trifle redder than at Claiborne, but a sin- 

 gle glance is enough to show they are the same. I noted 

 the following species among many others : Rostellaria 

 velata Con., Pecten Deshayesii Lea, Crassatella protexta 



• Con., Venericardla rotunda Lea, V. transversa Lea, 

 Turbinolia Maclurii Lea, Dentalium thalloides Con., 

 Astarte sulcata Lea, Corbida Murchisonii Lea, Gytherea 

 perovata Con., Cyth. cequorea Con., JFusus protextus 

 Con., Melongena alveata Con., Crassatella alta Con. 



No. 1. A blue sandy clay containing a few Claiborne 



fossils and a species of Osteodes 10 feet. 



Tombigbee River level. 



This should be convincing. 



Dr. Meyer in his opening quotation from Tuomey which is 

 given previously should have added the succeeding paragraphs. 

 I quote:* "Another locality occurs a few miles from Clarksville 

 on the land of Mr. Chambers, on one of the branches of Satilpa 

 Creek, where this fossiliferous (Claiborne) bed is laid bare by 

 the denudation of the upper beds and appears in the bottom 

 of a ravine, in the very midst of the White Limestone, at a 

 locality too where the latter rock is rich in the remains of Zeu- 

 glodon." Dr. M. leaves out of his authorities the Rev. C. S. 

 Hale.*]' The reader is referred to p. 360 where he gives two 

 localities near Claiborne (below) showing a section from the 

 Scutella bed (C. of my Claiborne profile) up to the Orbitoides 

 limestone. 



Winchell4 on page 84-85, gives two localities where the 

 Claiborne sand has the White Limestone above it, namely, 

 Stone Creek and in Clark County, Ala. 



The northern dip mentioned by Hilgard has its counterpart 

 in Alabama in several places ; in fact there is a large basin in 

 the Tertiary of Alabama, first spoken of by Tuomey, § proba- 

 bly with a smaller sub-basin north of it. Professor E. A.
