cerium from that characteristic of the Richmond. It was the Leipers 
form, from the vicinity of Nashville, which was figured by Parks as 
an illustration of his Stromatocerium huronense australe, and this is 
the specimen listed by Bassler as the holotype. 
In Kentucky, Stromatocerium is known from the Leipers division 
of the Maysville only from the Cumberland river exposures, between 
Harmon creek and Creelsboro, in the southern part of Russell 
county. Here it is associated with Tetradium fihratum, Escharopora 
him, Strophomena maysvillensis, Orthorhynchula linneyi, and Cyrto- 
ceras vallandinghami, a typical Leipers fauna. This Leipers fauna 
extends northeastward into Marion, Boyle, Garrard, and Madison 
counties, but farther northward apparently merges into the upper 
part of the Fairmount member of the Maysville, and only a few of 
the characteristic species reach the Ohio river.

In the accompanying sketch map, indicating these exposures of 
the Leipers member of the Maysville, along the Cumberland river 
in Kentucky, at which Stromatocerium was found, several interesting 
Richmond localities also are noted. In the northern part of Wayne 
county, opposite the mouth of Forbush creek, Stromatocerium was 
found associated with Columnaria vacua and Streptelasma rusticum. 
The Streptelasma was found also on Fishing creek, in Pulaski county, 
along a road leading west from Somerset. 
Stromatocerium occurs also north of the road from Liberty to 
Hustonville, on the northern side of Green river, nearly 2 miles
