Pg. 9, 17, 30. Falls City limestone member of Admire(?) formation. Usually one massive bed, brownish mottled, soft, resinous; hardens on exposure. Thickness 3 feet to 6 feet 4 inches. Lies 18 to 27 [37?] feet above Aspinwall limestone. Fossiliferous (pelecypods). Age is Pennsylvanian. Report includes measured sections, cross sections.

Falls City limestone bed of Admire shale member of Wabaunsee formation. Named the beds overlying Falls City limestone and underlying Americus limestone the West Branch shale, and the beds underlying Falls City limestone the Aspinwall shale; but in 1932 he discarded Aspinwall shale and named the beds immediately below Falls City limestone the Hawxby shale. Age is Late Pennsylvanian (Missouri age). Report includes cross sections, measured sections, geologic maps, stratigraphic tables.
On p. 82 Condra stated type locality of Falls City limestone to be in Lehmer quarry, in sec. 32, T. 1 N., R. 16 E., 2.5 mi south and 1.5 mi west of Falls City, Richardson Co., NE.

Pg. 5, 9. Falls City limestone formation of Admire group. At old Lehmer quarry, 4 miles southwest of Falls City and in lower course of Five Point Creek, includes (descending): Lehmer limestone member, 3 to 4 feet; Reserve shale member, 4.5 feet; Miles limestone member, 1+ feet. Overlies Hawxby shale formation and underlies West Branch shale formation, both of the Admire group. Age is considered Permian (lower part of Big Blue).

Falls City Limestone of Admire Group. Overlies Onaga Shale and underlies Janesville Shale, both of Admire Group. Conodont species association indicates the ADETOGNATHUS-SWEETOGNATHUS-STREPTOGNATHODUS biofacies; nearshore marine depositional environment. Age is Late Pennsylvanian (late Gzhelian; STREPTOGNATHODUS BELLUS conodont zone).
Described from measured sections in Chautauqua, Greenwood, and Pottawatomie Counties, eastern Kansas, and Osage County, northern Oklahoma. (Locs. 1, 2, 3, A12, A15, A26.)
