About sixteen miles west of Tallahassee, in See. 9, T. 1 S., R. 2 W., 
Dr. Vaughan 1 found an exposure of Miocene marl. The outcrop is 
on Duggar Creek, near the house of W. C. Allen; the material con¬ 
tains the same fauna and is lithologically similar to the Chocta- 
whatchee marl at Alum Bluff. 
On the farm of Jas. R. Harvey, one mile west of Holland P. O., 
a bed of very fossiliferous marl was encountered in a well at a depth 
of twenty-eight feet. The section encountered in digging the well is: 
Red ferruginous sand . 10 feet- 
Red and yellow sandy clay. 8 feet. 
Yellow Choctawhatchee marl becoming bluish gray below the'surface, 
water-bearing ... 7 feet 
From the material obtained from this well, a few fossils 2 were 
collected and they serve to show the age of the marl.

nks of. Mill Creek, the Chocta¬ 
whatchee marl has a thickness .of over thirty feet, but the exposures 
are poor. In the bed of the creek, the material ranges from blue to 
yellowish-gray in color, is not fossiliferous, but about twenty-five feet 
above the stream there is an exposure of about five feet of bluish gray 
shell marl containing fossils. From this bed a small collection was 
obtained, consisting of : 3
