The Compton limestone of southwestern 

 Missouri contains a fauna of Chouteau affin- 

 ity. It is overlain by the Northview forma- 

 tion which Moore (1928, pp. 126, 127) 

 considers to be equivalent in part to the 

 Chouteau (restricted) and to be perhaps 

 a clastic phase of the Chouteau. 



A study of the Chouteau corals leads to 

 several conclusions : 



1. The Chouteau limestone (restricted) 

 contains essentially the same fauna through- 

 out a large area and presumably it is every- 

 where of the same general age. 



2. The Chouteau fauna contains ele- 

 ments occurring in formations as old as the 

 Louisiana limestone and as young as the 

 Burlington limestone. 



3. Although the Sedalia and Chouteau 

 limestones contain many species in common, 

 they may be differentiated. 



4. The ''Rockford beds" of Indiana con- 

 tain species known from the Chouteau; 

 these strata are presumably equivalent to 

 some part of the Chouteau. 



5. Limestone beds at the base of the 

 Springville shale contain corals of Chou- 

 teau and Rockford affinities ; the thin lime- 

 stones may therefore be equivalent to the 

 Rockford limestone and to some part of the 

 Chouteau limestone. 



6. The Fern Glen species are almost all 

 distinct from those in the Sedalia and Chou- 

 teau limestones; the existing tentative cor- 

 relation of the Fern Glen and Sedalia is 

 therefore questioned. 



7. Among the most peculiar Carbonife- 

 rous coral genera are Palaeacis and Cleisto- 

 pora; because Palaeacis is known most abun- 

 dantly from the European faunal zones K 

 through C2 and Cleistopora from Zi and 

 Zo, it seems probable that the Chouteau 

 limestone is similar in age to some of the Z 

 beds of British stratigraphers.
