Plate V—Typical fossils of the Lansing, Douglas, Shawnee and Wabaunsee formations. Protozoans: Fusulina sp., examples of the small spindle-shaped fossils which are so common in many of the Pennsylvanian and Permian limestones of Kansas, 5, 6. Corals: Lophophyllum profundium, a small horn coral with very prominent central axis or pseudocolumella which in broken or weathered specimens may project from the calyx, 4. Echinoids: Archeocidaris aculeata, example of a sea-urchin spine which is common in some beds. Bryozoans: Fenestella shumardi, a delicate colony of the lace pattern type, natural size 17, enlarged fragment showing the apertures of the individual zooids, 17a; Rhombopora lepidodendroidea, a slender branching growth with the almost microscopic apertures of the individual animals on all sides, each aperture rhombic in shape, 15. Brachiopoda: Productus cora, a very common species with fine, somewhat flexuous ribs, ventral valve 2, dorsal valve 3; Chonetes granulifer, a gently concavo-convex shell with very fine radiating; ribs and short diverging spines along the hinge line, found in extraordinary numbers in some formations in Kansas, ventral valve 1; Meekella striatocostata, a shell of somewhat peculiar outline with large, rounded ribs marked by a pattern of finer ones, dorsal view 7; Spirifer cameratus, one of the most widely distributed and easily recognizable shells in the Pennsylvanian, its plications or ribs grouped into little bundles, dorsal view 9; Enteletes hemiplicata, a globose shell with small rounded beaks, coarse ribs which unite at the edges of the shell in a very jagged, zigzag line, and the surface marked by fine striations which radiate from the beaks, dorsal view 10, front view 11, side view 12; Hustedia mormoni, side view 16. Pelecypods: Limopteria longispina, a peculiar bivalte with a very long anterior wing and forward projection of the shell, side view 13; Edmondia aspenwallensis, a rather evenly convex shell with concentric, ridges, side view 14.

Plate XV—A. Section showing underground relations of rocks from the state line east of Paola to a point ten miles west of Osage City. B. Section showing underground relations of rocks from the state line east of Fort Scott to Burlington.
