PROSSER: UPPER CARBONIFEROUS OF SOUTHERN KANSAS. 155 
The massive limestone of No. 8, which weathers to a rough, 
jagged rock, is somewhat similar to a stratum twenty-six feet above 
the base of the Neosho formation in the Cottonwood valley,’ and 
it is referred to the Neosho formation. It seems probable that the 
base of the Neosho formation is either in No. 7 or 6, and the hori- 
zon of the Cottonwood limestone is also either in No. 7 or 6 of the 
Reece section. This would agree fairly well with the Cottonwood 
river section, where the Neosho formation has a thickness of 130 
feet and itis 144 feet from the top of the Cottonwood limestone ‘to 
the base of the Strong flint. 
If the above correlation be correct then the massive limestones 
forming Nos. 2 and 4 of the Reece section are in the Wabaunsee 
formation, possibly ninety feet or more below its top. The thick- 
ness of the rocks between the top of No. 4 and the supposed 
horizon of the Cottonwood limestone in this section agrees quite 
closely with the upper part of the Wabaunsee formation as exposed 
in the bluff of the Cottonwood river east of Elmdale. The Elm- 
dale section is as follows: 
No. Feet. 
6. Cottonwood limestone, light gray, containing large 
numbers of /wsuwd/na, near top of bluff. 
5. Mostly covered. Pie na pe ss BORet 65

2. A buff to light gray limestone containing /usudina, 4=%70 
from 3% to 4 feet thick. At the base greenish 
shales containing fossils in fair abundance as, Spirifer 
cameratus Mort, Athyris subtilita (Hall) Newb., 
Chonetes granulifera Owen, Productus semtreticulatus 
(Martin) de Koninck and others. 
1. Mostly covered to level of the Cottonwood river.... 66-66 
Another reason for referring the limestones of Nos. 2 and 4 of 
the Reece section to the Wabaunsee formation is the occurrence of 
Spirifer cameratus Mort. in the shales between them, which species 
has not been found above the Cottonwood limestone in the region 
where it is well shown. From the shales of No. 3 the following 
species were obtained:
