One-half mile southwest of Hannah's, bed d is well exposed 

 and shows a local dip of about i foot in 20. The fossils obtained 

 here consisted of casts; in fact, no fossils were collected by us in 

 Tennessee which retained any considerable amount of their shelly 

 substance. As nearly as we are able to determine such material, 

 the species represented are V. pianicosta var., Crassatella gabbi, 

 Calyptrophorus velatus and what seems to be an internal impres- 

 sion of Ostrea crenulintarginata. 



In and near the road at Mr. Huddleston's, 3 miles west of 

 Crainesville, the following- section was observed: 



a. White sandstone (fossiliferous), - - i foot. 



b. Clay, - - - - - - 20 feet. 



c. Clay-stone with green grains (fossiliferous), 2 feet. 



d. Clay, - - - - - - 15 feet. 



e. Clay-stone with green grains (fossiliferous), i foot.

It will be observed that the upper part of this section corres- 

 ponds well with that at Hannah's and is doubtless its equivalent. 



In the upper bed of the gray clay-stone with green grains the 

 following forms were collected: V. pianicosta var., Ostrea pulas- 

 kensis, Pholadornya mauryi, Tellina^ Cucullcea saffordi, Crassatella 

 gabbi, Calyptrophorus velatus, Yoldia eborea, Natica sp. 



The clay layer ' W yields impressions of Leda -milamensis and 

 Tellina as bed "/"" at Hannah's does. 



Five miles south of Crainesville a hillside about 400 yards 

 west of the highway is strewn in some places with ferruginous 

 blocks of sandstone containing many impressions of Venericardia 

 and Pectunculus (See pi. 4, fig. 3). The land is owned by Mr. 

 Markham. 



Middleton and vicinity. — Reference has already been made 

 (p. 8) to the fact that as early as i860 Dr. Safford sent Gabb 

 of the Philadelphia Academy some fossils from the neighborhood 

 of Middleton, Hardeman Co., Tenn. More particularly these 

 fossils were derived from three exposures*; one, "a bed of buff 

 gray, impure limestone from 2 to 6 feet thick. It is found on 

 both sides of the railroad near Muddy creek." "It is doubtless 

 the ' Turritella' and ' Bored ' limestone of Hilgard's sections Nos. 

 12, 13 and 14; pp. 86-88." The other localities show ''clayey 

 sand with green grains," and are two miles east and about two 

 miles south-southeast respectively from Middleton. 



SafFord following Gabb's identifications gives a list of fossils 

 from these localities as follows, — /being the limestone exposure
