since much thicker growths occur there also in the same horizon, 
some of them several inches in thickness. In fact, Lahechia monti- 
fera appears to be identical with Strpmatocerium huronense. At 
least, if distinct, the distinguishing characteristics have not yet been 
noted. 
* The type of Lahechia montifera is in the possession of George K. 
Greene, of New Albany, Indiana.

The type of Stromatopora indianensis was a characteristic 
specimen of Stromatocerium huronense from the Beatricea nodulosa 
horizon in the Elkhorn member of the Richmond, at Longwood, 
five and a half miles west of Connersville. At this locality, Stro- 
matocerium, associated with Tetradium, is common about 70 feet 
below the exposures of the Laurel limestone division of the Silurian. 
On Elkhorn creek, three miles southeast of Richmond, Indiana, 
Stromatocerium occurs immediately below the Brassfield limestone 
member of the Silurian, also 11 feet lower, and Beatricea is found 
both at 14 and at 29 feet below the Brassfield. In fact, both Stro- 
matocerium and Beatricea range throughout the Elkhorn member, 
although usually confined at each locality to only one or two hori- 
zons. 
The type of Stromatocerium indianense had the characteristic 
large and prominent mamellate elevations of the Richmond species, 
Stromatocerium huronense. It was a massive specimen 8 inches 
long, 6 inches wide, and 5 inches high. It can no longer be found 
among the specimens preserved in the U. S. National Museum, but 
there is no doubt as to identity of the species.

Stromatocerium huronense australe was described from a series 
of Kentucky Richmond forms belonging to the Ulrich collection, 
deposited in the U. S. National Museum, at Washington; but the 
only figured specimen, also from the Ulrich collection, was obtained 
in the Leipers division of the Maysville, near Nashville, in Tennessee.
