**Present usage of the Geological Survey of Canada (Douglas, 1970) assigns the terms Caribooan to the Devonian-Mississippian orogenic episode. I think this is unfortunate. The terms Antler and Ellesmerian have already become synonymous in the time sense; the use of the term Caribooan for their exact equivalent in the stretch between their two type localities makes three terms synonymous. The original definition of Caribooan (White, 1959) does not preclude its use for the significantly earlier orogenic episode that led to the first continental crust beyond the Canadian shield and to the sub-Devonian unconformity throughout western North America. This episode has now been assigned convincingly to the Middle Devonian (Boucot and others, 1974); it is earlier than and independent of the Antler-Ellesmerian orogeny.
