TOPEKA SECTION. 
A general section of the rocks of Topeka, Kan., with their fossils is given in 
the preceding volume of these Transactions (page 27). The parts of the section 
here given are from the Topeka limestone to the Burlingame limestone, inclusive, 
in a more detailed manner and with the fossils grouped for comparison with the 
Nebraska City section. The Topeka limestone is exposed in the Shawnee county 
quarry, at the fair-grounds in the southern limits of the city; also a mile and 
a half southeast; and at Calhoun bluffs, three miles northeast of Topeka. 
Bennett’s description of the beds is the best that has yet appeared, and is 
here given in full: * 
‘*TIn an exposure a mile east and a mile south of Topeka there is a showing of 
the upper section of the underlying shales. About six and one-half feet below the 
top of the underlying shales a fairly good building sandstone is reached, which is 
three feet thick. The lower limestone of the Topeka system is six feet thick, and 
is blue, but weathers dark buff. Above it is a foot and a half of blue shale, then 
above that five feet eight inches of blue and brown limestone, having a cherty 
layer near the top. Above this comes two feet of buff shale, and then again lime- 
stone one and one-half feet thick, above which are three feet of drab shales, which 
are again capped by two feet of limestone.’’ 
Bennett gives the following list of fossils as collected in this limestone: 
Fusulina cylindrica, Chetetes and a ramous form of Chetetes, Archeocidaris 
, Zeacrinus mucrospinus and Zeacrinus acanthropus, Fenestella ; 
Chonetes granulifera, Productus punctatus, Productus longispinus, Productus 
costatus, Productus prattenianus, Athyris subtilita, Spirifer cameratus, Strepto- 
rhyncus crassus, Terebratula bovidens, Retzia mormoni, Bellerophon carbonarius.

ten other species which seem to be of the genera Fenestella, Poly pora, Streblopora, 
Stenopopora, and Blatostomella.
