APPEI^DIX. 



In Professor Emmons's Report on tlie Geology of North Carolina are 

 descriptions of a few Eocene fossils, some of which I am unable to arrange 

 stratigraphically : — 



ECHIIVODERMATA. 



Cidaridae. 



1. Cidaris Mitchelli, Emmons. N. Car. : Jackson Group. 



2. Cidaris carolinensis, Emmons. N. Car. : Jackson Group. 



Clypeasteridae. 



3. Echinocyamus parvus, Emmons. N. Car. 



4. Scutella Lyelli, Emmnns. N. Car. 



5. Gonioclypeus subangulatus, Emmons. N. Car. 



Crinoidea. I' 



6. Microcrlnus conoideus, Emmons. N. Car. 



POtYZOA. 



Escliaridae. 



7. Lunulites contiguus, Emmons. N. Car. 



' I believe this to be the masticatory apparatus of Mortonia altus. It 

 is certainly no Crinoid.
