but persistent Fetzer formation. The name is taken from Paperville, near Bris- 
tol, Bristol (T.V.A. 206-SW) Quadrangle, where the shales are well exposed. 
The type section is along Steele Creek, near Paperville, and has been described 
by Decker (1952, pp. 39-47), who collected representatives of many well-known 
Normanskill graptolites from these beds. The Paperville shales are capped by 
the ridge-making calcareous brown-weathering sandstones of the “Tellico” 
formation. Few brachiopods are known: 
Ectenoglossa nymphoidea Cooper 
Obolus biconvexa Cooper 
Peery formation.—This name was proposed by Cooper and Prouty (1943, 
p. 863) for a sequence lying between the Ward Cove and Benbolt formations. 
It consists of a lower cherty limestone, thin-bedded and dark gray, weathering 
to ash gray. The upper part of the formation is a dove-gray calcilutite. The 
lower part averages 30 feet thick, but the upper part is usually less than 50 feet 
thick although it reaches 140 feet at one locality. The best development is north- 
west of Clinch Mountain. The formation is also present on the southeast side 
of Clinch Mountain but is usually less than 20 feet thick. On this side of Clinch 
Mountain the Peery overlies Rich Valley limestone but underlies Benbolt shale. 
In the Peery, on the northwest side of Clinch Mountain, fossils are com- 
mon but poorly preserved in the lower part; they are uncommon and poorly 
preserved in the upper part. B. N. Cooper reports, with additions of new forms, 
the following brachiopods: 
Ancistrorhyncha crassa Cooper 
Mimella sp. 
Multicostella sp. 
Sowerbyella aequistriata (Willard) 
S. delicatula Butts = ? Leptellina delicatula (Butts) 
S. ci. S. negritus (Willard) 
Sowerbyella sp. 
Sowerbyites sp. 
Strophomena fasciculata Cooper 
S. “filitexta’ (Hall) = S. basilicoidea Cooper 
S. tenuitesta Willard 
Pelham limestone.—This is a broad name that is nearly equivalent to Chicka- 
mauga limestone because it embraces the interval from the top of the Knox to 
the Clinton. The name was long neglected while Chickamauga was becoming 
entrenched in the literature. Actually neither name now has any value because 
the Chickamauga sequence of Georgia and the Pelham of Alabama can be divided 
into several formations ranging in age from Marmor to Trenton or higher. 
Pinesburg member of Shippensburg formation.—This name was proposed 
by Craig (1949, p. 718) for 140 feet of cobbly and slabby limestone. The type 
section is on the south side of U. S. Highway 30, 1 mile S. 70° W. of St. Thomas, 
Pa., although the name is taken from Pinesburg Station in Maryland. The 
lower part of the member is of platy-weathering limestone, the middle part (73 
feet at type section) of cobbly limestone, and the upper 36 feet of dark-gray platy
