PROSSER: UPPER CARBONIFEROUS OF SOUTHERN KANSAS. 163 
CORRELATION AND PaLEonroLtoGy.—For the purpose of classifi 
cation it is more convenient to begin with the upper part of this 
section, which is readily correlated. The massive limestone—No. 
27—in the railroad cut east of Grand Summit, forms the lower part 
of the Strong limestone at the base of the Chase formation. Above 
the limestone are the yellowish and bluish shales—No. 28—which 
contain abundant fossils. Here the larger number of fossils have 
been collected that are credited to Grand Summit, Cowley county. 
These shales correspond to the fossiliferous shales—No. 14—of the 
section west of Reece. The most abundant species are Productus 
nebrascensis Owen, many very perfect and beautiful specimens of 
which occur in great numbers; Meekella striato-costata (Cox) White 
and St. John; AZyalina Kansasensts Shum.; and MW. Swadllovi Me- 
Chesney. The following is the complete list collected in about 
one hour:
