Stromatocerium horizon. — Overlying this Curds- 

 ville horizon is one in which Stromatocerium is abundant. 

 There probably is an unknown interval between this and 

 the Curdsville, since most of the specimens of Stromato- 

 cerium are found along the southwestern side of Goat 

 island. 



Prasopora simulatrix horizon. — The lowest strata 

 found at the water's edge directly east of Little Current 

 represent a higher Trenton horizon. In the lower part of 

 the section in this locality, 5 feet (1.5 m) thick, Prasopora 

 simulatrix occurs in argillaceous limestone, accompanied 

 by other bryozoans suggesting an age approximately 

 comparable with the Nematopora bed or upper Prosser of 

 Minnesota. Fossils occurring in these beds are : —
