Correlation of Ward Cove formation.—This formation in the western belts of 
Virginia takes the place of the Arline formation and has species related to the 
Arline. 
Wardell formation.—This formation was proposed by Cooper and Prouty 
(1943, p. 873) with type section near the settlement of Wardell near the Taze- 
well—Russell County line. The formation has a thickness of 200 feet or more 
in median and southeastern belts of the Appalachians in Virginia and Tennessee. 
The lithology is variable and consists of limestones, calcarenites like the Effna, 
dove calcilutites, and shales. Where the Gratton is not present the formation 
is difficult to separate from the Benbolt, as at Rye Cove, and the two combined 
are known as Dryden formation. The fauna, however, is very prolific and 
abounds in brachiopods. The list includes identifications by Cooper and Prouty 
with additions by the writer:
