CARBONIFEROUS. 383 



In No. 1 of the above section there are Bellerophon, Pinna, AUorisma, and 

 Nautilus f. From between the upper beds of limestones of this section 

 there issues a bold, running spring, that flows into Rough Creek.

Some of the limestones in this section would make excellent building ma- 

 terial when there shall be a demand for it. The formation here very much 

 resembles that just west of the town of Baird, and is probably the same. It 

 is the beds I have elsewhere called "Albany Beds," and is the same as seen 

 at the head of North Hubbard Creek, in Shackelford County, northwest of 

 Albany. The coral Syringapora multattenuata is very abundant, occurring in 

 large masses in the clay and limestones. There were also Synocladia, Macro- 

 cheilus, Aviculopeden, and Myalina. 



SECTION NO. 32, ALBANY DIVISION. 



In McCoy's pasture, on the south side of Pecan Bayou, and below the forks 

 of the bayou. The top of this section is eighty feet below the base of the 

 previous section.
