denticles rather prominent and strong ; line of base nearly 

 horizontal ; roots spreading widely, forming a very obtuse 

 angle with each other. 



I have referred also the following figures of teeth to the 

 genus otodus : 82, 83, 84, 85, 86, 87, 88. They all belong to 

 the eocene formation, and occur in a layer near the top. They 

 are from the plantation of Mr. Wadsworth, of Craven county.

GENUS CORAX. 



The following figures of teeth found in the eocene of Craven 

 county. I am unable to refer them to species already describ- 

 ed, viz : 82, 83, 84, 85.

GENUS ODONTASPIS. (Figs. 86a, 87a, 88a, 89a.) 



This genus should have followed larnna: 

 I now introduce it for the purpose of re- 

 ferring to odontaspis, (figs. 86 and 87,) 

 which appear to belong to this genus ra- 

 ther than lamna. So, also, figs. 88 and 

 89, which are destitute of basal denticles : 

 but the cutting edge of the crown extends 

 over the fangs and is slightly expanded 

 on this part of the tooth; it preserves also 

 its cutting edge. Eocene of Craven county. 

 I have no facilities at hand which en-

 eocene odontolites, and have to trust to
