Thompson Valley formation.—Prouty (1946, p. 1152) proposed this name 
for the coarse calcarenite in the lower part of the Ward Cove formation in parts 
of Virginia and East Tennessee. It is the coarse-grained limestone mentioned 
by B. N. Cooper (1944, p. 42) in the Burkes Garden Quadrangle report. Prouty 
thus restricted the Ward Cove formation to the finer-grained limestone in which 
Nidulites is abundant. The Thompson Valley formation is best developed in the 
median belts of the Appalachian Valley and occurs locally in the northwestern 
belts. The formation thus overlies Lincolnshire (or Hogskin member) and 
underlies the restricted Ward Cove. The name does not appear on the chart. 
The following brachiopods have been reported: 
Dactylogonia magnifica Cooper Oligorhynchia subplana Coope1 
Dinorthis atavoides Willard O-xoplecia holstonensis Willard 
Mimella sp. Schizambon sp. 
Toqua formation (R. B. Neuman, 1956).—This is a name for a sandstone 
facies of the Blockhouse formation which replaces the dark shales to the south- 
west along the base of the Great Smoky Mountains in East Tennessee. The 
Tellico sandstone in the section at Cisco, Ga., may be in part Toqua sandstone. 
Tumbez formation.—This formation was defined by B. N. Cooper (1945b, 
p- 133) with type section I mile south of Tumbez, Russell County, Va. It con- 
sists of a basal boulder conglomerate succeeded by dolomite, mudrock, and 
calcarenite containing Rostricellula basalaris and Mimella nuclea. It underlies 
Elway and overlies the Mascot dolomite (Lower Ordovician) unconformably. 
The formation is equivalent to the Rostricellula beds of the Lenoir and is also 
well displayed under the Maclurites beds in a small quarry 3.4 miles southwest 
of Marion, Va.

Valentine member of Curtin formation (Kay, 1944, p. 21).—Pure quarry 
rock, dove calcilutite in central Pennsylvania. The only brachiopod so far 
reported is a large Lingula sp. 
Valley View member of Curtin formation (Kay, 1944, p. 20).—This is 
the lower member of the Curtin formation of central Pennsylvania from which 
no brachiopods have been reported or seen by the writer in sections studied 
by him. 
Vestal marble.—This name is applied to a marble 150 to 200 feet thick near 
the base of Sevier formation on the south side of Knoxville. It has about the 
same position as the Meadow marble.
