NO. 5 PRE-DEVONIAN PALEOZOIC FORMATIONS 195 



Banff limestone and Intermediate limestone were bracketed under 

 " Devonic " and called Banff limestone and dolomite. " Lower half 

 probably Mid-Devonic." 



With our present information the Banff series and Intermediate 

 limestone of McConnell are classified as shown on opposite page. 



McConnell correlated the great limestone series beneath his Inter- 

 mediate limestone in the Sawback Range with his Castle Mountain 

 group. Later, Allan included these limestones under the name Saw- 

 back formation, which I have in this paper assigned to five formations 

 (see Sawback formation, p. 190).
