In the shaly limestones at the hates of Nig 4, in the second rail- 
road cut, and in the yellowish to grayish shales at the top of No, 
2, in the first railroad cut, is an abundant fauna of the Neosho for- 
mation. The list is as follows:

The massive flint and concretionary limestone—No. 5—at the 
top of the above section is the base of the Stong limestone, below 
which is the Neosho formation; while possibly the light gray /usu- 
Zina limestone of No, 1 represents the Cottonwood limestone. On 
the western side of Grouse creek, at Dexter, the base of the S Strong 
flint is 135 feet above the creek level; but the creek banks are cov- 
ered by alluvial deposits, so that we were unable to find any expos- 
ures of rocks near the horizon of the Cottonwood limestone. Ina 
railroad cut at Sliding Bluffs, on the western side of Grouse creek, 
two and one-half miles west of north of Dexter, is an excellent 
exposure of the lower part of the Strong limestone and subjacent 
shales. The flint shows prominently in the limestone and below it 
are yellowish shales and shaly limestones in which fossils are 
abundant, especially Derdya multistriata (M. and H.) Pros. , The 
other species are:
