Mount Hope member, with Amplexopora septosa, Batostoma mays- 
villensis, Callopora communis, Callopora nodulosa, Constellaria 
prominens, Escharopora falciformis, Heterotrypa sp., Perenopora 
vera, and Strophomena maysvillensis. 
Limestone and clay 5 ft. 6 in. 
Chiefly clay, with Dekayella ulrichi and Callopora sigillarioides, 
belonging to upper or McMicken member of the Eden. . 3 ft. 
Limestone and clay 14 ft. 6 in. 
Chiefly clay, with Dekayella ulrichi 5 ft. 6 in. 
Chiefly clay, with some limestone, containing Dekayella ulrichi, 
Callopora onealli, and, near the middle, also several large speci- 
mens of Platystrophia, resembling PI. ponderosa 9ft. Gin. 
Chiefly clay, with a limestone layer at the top and bottom 10 ft. 
Clay, with Batostoma implicatum, Ceramoporella milfordensis, Deka- 
yella ulrichi, and Perenopora vera 3 ft. 6 in. 
Limestone layers, wave-marked at the top - 2 ft. 
Limestone with Platystrophia, 1 inch wide, very rare 4 in. 
Clay 3 ft. 6 in. 
Chiefly hard limestone 2 ft. 6 in. 
Clay 3 ft. 
Wave-marked limestone, with Strophomena hallie 4 in. 
Chiefly clay 4 ft. 
Limestone and clay, with Strophomena hallie rather common in some 
of the lower layers. Constellaria occurs in one layer near the 
base. Also, Batostoma implicatum, Dekayella ulrichi, Perenopora 
vera, and Stigmatella clavis 12 ft. 
From the preceding notes it may be seen that Strophomena 
hallie occurs at Maysville between 63 and 80 feet below the top of 
the Eden. This horizon is regarded as belonging to the upper 
part of the middle or Southgate member, although it has not been 
found possible to draw a sharp line between the upper and middle 
member, diagnostic fossils not having been found. 
Strophomena hallie occurs also in the upper part of the tunnel 
cut, along the railroad, 2 miles northeast of Carlisle, Kentucky. 
Tt is common in the Eden in the railroad cut immediately east 
of the home of George Million, about 4 miles northwest of 
Richmond, Kentucky. At the latter locality, it occurs only a 
short distance below the massive Paint Lick or Garrard member, 
and is associated with a large form of Platystrophia, 1 J inches in 
width, resembling a young quadrate Platystrophia ponderosa. Also 
Fusispira terehriformis, Amplexopora septosa, Constellaria prom- 
inens, Dekayella ulrichi, Escharopora falciformis, Hemiphragma 
sp., Heterotrypa sp., and Perenopora vera. In a general way, this
