PART I CHAZYAN AND RELATED BRACHIOPODS—COOPER 89 
is now known not to be Murfreesboro, and the limestones have been placed in 
other formations. 
St. Luke member (facies) of Edinburg formation.—This name was pro- 
posed by Cooper and Cooper (1946, p. 81) for dove-gray massive limestone beds 
and calcarenites occurring between the Oranda formation above and the Nidu- 
htes-Lambeophyllum beds of the Edinburg formation below. At the type locality, 
1 mile S. 60° E. of St. Luke, Va., the member is go feet thick. It is often com- 
posed of calcarenite which contains Cryptophragmus. 
Brachiopods taken from the St. Luke member are: 
Doleroides sp. Rostricellula sp. 
Oligorhynchia bifurcata Cooper Zygospira sp. 
Opikina sp. 
Correlation of St. Luke member.—The St. Luke is correlated by Cooper and 
Cooper (1946, p. 86) with the Witten formation. The presence of Cryptophrag- 
mus, Zygospira, and Oligorhynchia aid in making the correlation. 
St. Paul group.—This term was proposed by Neuman (1951, p. 278) as a 
substitute for the outmoded and erroneous name “Stones River” as applied 
throughout West Virginia, Maryland, and southern Pennslyvania. The type 
section is located near St. Paul’s Church, Md., at the intersection of U. S. High- 
way 40 and Maryland Highway 57, 9 miles west of the center of Hagerstown. 
The group consists of the Row Park formation at the base and the New Market 
formation at the top. 
Salona formation.—This formation extends from Pennsylvania into northern 
Virginia. It consists of black or dark argillaceous limestone and dark calcareous 
shale usually with numerous fossils. In Virginia it overlies the Oranda forma- 
tion and is more shaly than is usual in Pennsylvania. In the latter State the 
Salona formation overlies the Rodman member of the Nealmont formation. In 
Virginia much of the Salona fauna appears to have been inherited from the 
underlying Oranda formation. A similar condition is true in Pennsylvania be- 
cause some of the Rodman elements pass into the Salona. The trilobite Brongni- 
artella is the most significant marker of the Salona formation. 
Brachiopods are numerous. For a faunal list of the Salona fauna in Virginia, 
see Martinsburg. Additional brachiopods from the Salona (Kay, 1944, p. 112) 
of Pennsylvania are: 
Colaptomena leptostrophoidea Cooper 
Conotreta rustit Walcott 
Dalmanella sp. 
Leptaena sp. aff. L. rhomboidalis (Wilckens) = L. ordovicica Cooper 
Leptelloidea pisum (Ruedemann) = Bilobia hemispherica Cooper 
Oxoplecia sp. cf. simulatrix (Bassler) = O. pennsylvanica Cooper 
Parastrophina hemiplicata (Hall) 
Porambonites sp. = Porambonites sp. 4 
Salonia magnaplicata Cooper and Whitcomb 
Sowerbyella cava Cooper 
Sowerbyella sp. 
Strophomena sp. 
Rafinesquina sp.
