the famous lithographic beds of Solenhofen, Bavaria. Fossils 
are of rare occurrence, but there are included a few species 
also found in the Chouteau limestone. On the Osage and Sac- 
rivers is a bluff of Magnesian limestone which has been re- 
ferred to the age of the Lithographic. At Taberville it con- 
tains Peutremites rasmeri, and other Peutremites. Prof. 
Swallow reports finding in it Spirifer marionensis, 8p. Cuspi- 
datus, Productus murchisonianus (P. shumardanus), Proetus 
missouriensis, Plumulites gracilis and Taonurus canda-galli. 
About one-half of the fossils found in the Lithographic beds 
are also found in the Devonian. 
The Vermicular sandstones and shales contain nearly all 
typical Chouteau fossils. This formation reaches to 100 feet 
thickness in Pike county. 
The term Vermicular was applied by Prof. Swallow on ac- 
count of its being generally traversed in various directions 
by small worm-like windings. I have observed it presenting 
this appearance in Ralls, Cedar and Green and other counties. 
At Cedar Gap and Dunnigan's Mill, in Cedar county, it con- 
tains typical Chouteau fossils, including Allorisma hannibal- 
ensis, Phillipsia and JEntolium cooperensis. The Chouteau 
limestone is generally of a dull drab or dove color. At Seda- 
lia the course brownish-gra} T Burlington is separated by a few 
feet of fossil shales from the underlying Chouteau limestone. 
The Chouteau in this neighborhood contains numerous vermi- 
form chert concretions. In some places it also contains small 
geodes having a rugose appearance. At Sedalia the top shales 
often abound in corals as Mitchellinia placenta, M. convexa, 
Lithostrotion, Chonoplyllum sedaliense and Zaphreutis <■"/>■,-

*Mr. R. A. Blair, of Sedalia, has kindly donated to me many of these 
fossils. ■
