Art. XXXIITL—On New Fossil Corals from North Carolina; by 
HE. Emmons. (From a letter to one of the Editors.) 
1. Talcose slates in connexion with granite or gneissoid 
ite 
2. Brecciated conglomerate from 300 to 400 feet thick. Parts 
of this mass are porphyrized. 
3. Slaty breccia associated with chert or hornstone. 
4. Granular quartz, which is in part vitrified and filled with 
this fossil and with siliceous concretions, which are about the size 
of almonds. It is 250-800 feet thick. 
5. Slaty quartzite, its fossils much less numerous. It is 40 
feet thick. 
6. Slaty sandstone without fossils, 50 feet. 
7. White quartz, more or less vitrified, filled with fossils and 
almond-shaped coneretions. 
8. Jointed granular quartz, similar to that of Berkshire Co., 
Mass., with only a few fossils. 
9. Vitrified quartz without fossils, 30 feet thick. 
10. Granular quartz, no fossils, thickness great, but unde- 
rmined,

11. Overlying these siliceous beds is a clay slate like that so 
common in Ranascaat and Columbia Cos., N. York. As yet, it 
has yielded me no fossils. The slate as a whole, remains un- 
changed, but frequently contains vitrified beds, or silicified ones, 
the origin of which I do not propose to speak of at this time.

It is evident the fossil is a coral. Among the specimens I think 
I can recognize two species. The generic name which I have 
given it is Pale@otrochis, “ Old Messenger,” the smaller is the P. 
manor (fig. 1), the larger, P. major, fig. 2.
