(Adams, MSS., by permission of U. S. Geological Survey.) Base of the Wabaunsee formation. For the present it seems best to group several strata in this formation.[9] They cannot well be mapped on the scale of the U. S. folios, and they are also intimately connected faunally, and usually all assist in producing a high escarpment with the upper part retreating. The rocks aggregate about seventy feet in thickness. The following section will serve to give an idea of these rocks: ft. in. _g._ Gray, argillaceous, fossiliferous limestone, from 1 foot 2 0 to _f._ Bluish calcareous shales with _Enteletes_, _Myalina_, 20 0 _Allorisma_ and _Bellerophon_ fauna, from 8 feet to _e._ Hard, shelly, bluish limestone 4 0 _d._ Shales with thin limestones, varying from 21 feet to 40 0 _c._ Hard gray limestone weathering light yellow, from 1½ feet 1 0 to _b._ Thin layer of shale 0 6 _a._ Massive yellowish-gray limestone, very hard, with but few 6 0 fossils, from 4 to 7 feet thick, averaging about Most all of the fossils listed below are from layers _e_, _f_, and _g_, by far the greater part ranging through all three. _Somphospongia multiformis_ Beede (from Robinson, Brown county). _Aulacorhynchus millepunctatus_ (Meek and Worthen) Hall and Clarke? _Derbya crassa_ (Meek and Hayden) Waagen. _Dielasma bovidens_ (Morton) White. _Enteletes hemiplicata_ (Hall) Hall and Clarke. _Meekella striaticostata_ (Cox) White and St. John. _Productus cora_ d’Orbigny. _Productus punctatus_ (Martin) Morton. _Seminula argentia_ (Shepard) Hall. _Allorisma costatum_ Meek and Worthen. _Allorisma geinitzi_ Meek. _Allorisma granosum_ (Shumard) Meek. _Allorisma subcuneatum_ Meek and Hayden. _Allorisma_ sp. _Aviculopecten occidentalis_ (Shumard) Meek and Hayden. _Edmondia aspenwallensis_ Meek. _Edmondia ovata_ Meek and Worthen. _Edmondia_ cf. _nebraskensis_ Meek. _Macrodon_ sp. _Myalina perattenuata_ Meek and Hayden. _Myalina subquadrata_ Shumard. _Pinna peracuta_ Shumard. _Pleurophorus_ sp. _Pseudomonotis kansasensis_ Beede. _Pseudomonotis hawni_ Meek and Hayden. _Pseudomonotis_ cf. _robusta_ Beede. _?
