Waynesville bed, but it can not be said to be common. Spec- 
imens of this size are found also at the top of the Middle 
Richmond at Dayton, Ohio, and at the top of the ^Madison 
bed southeast of Westport, Indiana, but are rare.

bona, Str. neglecta, Str. vetusta, Str. nutans, Str. sulcata. 
Strophomena hallie is cited from the Lower and ^Middle 
Utica. At Vevay it occurs in the Middle Utica, between loo 
and 120 feet below the base of the Lorraine, associated with 
Amplexopora peta.nformis, also the variety ivelchi, Aspido- 
pora nezvberryi, Aspidopora eccentrica, Batostoma impUcatum, 
Ceraiiioporella grannlosa-milfordensis, Hemiphragma whit- 
Heldi, and Stigmatella clavis. Between 120 and 128 feet be- 
low the base of the Lorraine the section contains Monotrypa 
subglobosa and Stigmatella nana. A number of Lower Utica 
forms evidently range higher than hitherto suspected. At the 
junction of Mud Lick and South Fork, half a mile south of 
Milton, Strophomena hallie occurs at the base of the L^p- 
per Utica, 85 feet below the base of the Lorraine, associated 
with Batostoma jamesi, Callopora nodulosa, Coeloclema alter- 
natum, Dckayella 'iilrichi, and other fossils of general range. 
North of Rogers Gap, in Kentucky, Str. hallie occurs, in 
the lower part of the Utica, associated with DalmancUa nnil- 
tisecta and D. emacerata. 
Strophomena planiconvexa, in southern Indiana, occurs 
quite constantly, although in small numbers, near the base of 
the Lorraine, at the top of the bryozoan layer or just above. 
At Vevay it ranges from three to eleven feet above the base ; 
at Brooksburg it is eight feet above. 
Four miles north of Vevay, on the Plum creek road about 
two miles south of Jacksonville, this species recurs 52 feet 
above the lower Strophomena planiconvexa horizon, and 
about 33 feet below the lower Platystrophia lynx or Bellevue 
bed. Three miles east of this locality, in the southwest cor- 
ner of section 14, opposite the home of J. W. Evett, a large 
typical gerontic lower Lorraine specimen of Platystrophia 
lynx occurred in the same slab with Strophomena planicon- 
vexa at this upper horizon. The upper horizon is exposed also 
along the upper part of the road ascending the hill east of 
■Scott chapel, three miles north of Florence, along tlie eastern
