between the Parsons limestone and the Hertha limestone, 

 which, as explained above, in the discussion of the synonym, 

 are the equivalent of Haworth's Lower Pleasanton shales." 

 We apply the name Walnut for a portion covered by Adams's 

 name Dudley, for the following reasons: First. The town of 

 Dudley does not rest on these shales at all, but on the Ladore 

 shales, named by Adams, which name we adopt, and which lie 

 above the Bethany Falls limestone. Second. Adams, under the 

 name Bandera shales, says, page 32: "These shales are the 

 equivalent of the Lower Pleasanton shales of Haworth." This 

 latter statement is correct, making the statement that the 

 Dudley shales correspond to Haworth's Lower Pleasanton 

 shales impossible. Third. We want a name for the shale-beds 

 above the Altamont limestone and below the Coffeyville lime- 

 stone, but Adams did not recognize the Coffeyville limestone, 

 so spread the name from the Altamont to the Bethany Falls 

 limestone, thereby crowding out Haworth's Lower Pleasanton 

 shales, which, by all the laws of priority, should be retained. 

 The name Walnut shales, therefore, is applied by us to the 

 shales above the Altamont limestone and below the Coffeyville 

 limestone. 



Coffeyville Limestone. — The name Coffeyville limestone 

 is here used for the first time. It is applied to the limestone so 

 prominent at Coffeyville, from which place it takes its name. 

 It is the limestone spoken of as the Upper Altamont or Par- 

 sons by Adams," whose error was due to a lack of detailed in- 

 formation. Since his last publication on the subject, this lime- 

 stone has been traced with great detail by Bennett, who has 

 been able to determine without question that it is a separate 

 limestone formation extending entirely across the corner of 

 the state. Its independent existence warrants us in giving it 

 a distinct name. 



Pleasanton Shales.'' — The term Pleasanton shales was 

 first introduced by Haworth in 1895. At that time it was ap- 

 plied to the entire mass of shales lying above the Pawnee lime- 

 stone and what was then called the Erie limestone, the lower 

 member of which was called the Bethany Falls limestone, and 

 will so appear in our next volume. The intervening Altamont 

 and Coffeyville limestones were not known at that time.
