the fauna at the base of the Hermitage. According to McFarlan (1931, p. 50), 
the Hermitage of Kentucky is characterized by large Dinorthis and Heterorths. 
It is the writer’s belief that the correlation of the Heterorthis assemblage with 
the Curdsville is not correct. Hermitage brachiopods besides those listed are: 
Dalmanella crassicostellata Cooper 
D. sulcata Cooper 
Dinorthis pectinella (Emmons) 
Onniella ? americana Cooper 
O. ? planoconvexa Cooper 
Pionodema tennesseensis Cooper 
Platystrophia extensa McEwen 
Rafinesquina hermitagensis Bassler = R. trentonensis (Conrad) ? 
Rhynchotrema “increbescens” 
Rostricellula minuta Cooper 
Zygospira “recurvirostris” (Hall) 
WELLS CREEK BASIN 
The Wells Creek Basin is a small cryptovolcanic structure located in south- 
eastern Stewart County in north-central Tennessee. Bucher (1936, p. 1069) 
described the structure and some of the stratigraphy of the basin. C. W. Wilson 
(1949, p. 324-325) gives the most complete section and identifies the Ordovician 
formations for the first time. Most of the formations of the Stones River group 
are present, as follows: 
RoweriGarters members, gOs954. 2czis SERINE SA PAS SE (100 feet, est.)

The lowest formation rests on the Wells Creek dolomite of Canadian age and 
the lower Carters member is overlain by 100 feet (estimated) of Hermitage. 
In 1903 Foerste (p. 705) applied the name “Wells” to limestones about 14 
miles southwest of Cumberland City, along the railroad, about 4 mile south of 
the crossing of the Erin Pike. The fossils from these beds were identified as an 
upper Stones River assemblage. The brachiopods listed by Foerste are: 
Acanthocrania cumberlandensis (Foerste) 
Crania related to setigera but with surface spinose 
Dalmanella subaequata var. = ? Pionodema minuscula Willard 
Dinorthis deflecta= ? Chaulistomella 
Hallina nicolleti = Protozyga 
Orthis tricenaria = Hesperorthis tricenaria (Conrad) 
*Plectambonites sericea = Sowerbyella 
*Rafinesquina minnesotensis = Opikina 
Rhynchotrema related to inaequivalvis but with more triangular outline and with the sides 
more flattened, producing a more angular shell; probably identical with Rh. orientalis of 
Safford. This description suggests Rostricellula compressa Cooper. 
*Strophomena incurvata (filitexta) 
Zygospira recurvirostris
