the State iGl-eologioal Survey (for the use of which I am indebted to the 
'Director, Mr. E. T. Dumble, and to Dr. E,. A. F. Penrose, Jr., the geologist 
of the Tertiary areas of the State) are by far the most extensive, and they 
serve to definitely locate the formations whence the fossils were obtained 
in their true positio'n in the geological scale. Of some 145 species here 
enumerated (including a few doubtfully determined forms) about 61 (or 
upwards of 40 per cent.) are also members of the Claiborne fauna of 
Alabama; these I have indicated by prefixing an asterisk. A few others 
occur in some of the older deposits of Alabama, while a very few are mem- 
bers of the Mississippi (newer) fauna. The recurrence of a large number 
of the species in various counties and localities indicates that the horizon 
is a common one, namely: the Claibornian, or typical Middle Eocene of the 
Gulf slope, the equivalent of the 'Calcaire Grossier of the Paris Dasin. 
‘The principal localities whence the fossils were obtained are Cherokee 
county, near Alto and McBee’s School; Palestine, in Anderson county; 
lEobertson county, near Wheelock; Milam Bluff in Milam county; Burle- 
son IShell Bluff in Burleson county; 'Smithville, Devil’s Eye, Bombshell 
Bluff and ‘Camp Disaster,’ in Bastrop county; Caldwell county; Atascosa 
county; Laredo, in Webb county, and , Stations 1-5 on the 'Bio Grande river, 
included between Carrizo and “Cardita Bluff,’ in the northwestern corner 
of Webb county.” 
The list, without notes or descriptions of new species, is as follows:
