•Note: The bryozoa in this and the following lists were identified by 

 Professors E. R. Cumings and J. J. Galloway. 



Of the fossils in the foregoing list that are present also 

 in the Richmond strata of Indiana, 12 species occur there 

 in the Waynesville formation and do not appear in 

 younger Richmond strata. Eleven other species occur in 

 Indiana in both the Waynesville and the Liberty forma- 

 tions. Twelve of the species range from the Waynes- 

 ville to the Whitewater formations. None of the species 

 are restricted to the Liberty formation in Jndiana, and 

 only one of the number is found in Indiana only in the 

 Whitewater formation. Such species as Dinorthis sub- 

 quadrata that is not present in Indiana in the Waynes- 

 ville, but occurs there in both the Liberty raid White-
