 of the type material is to be found in the U. S. National Museum, 

 and the writer is under obligations to Dr. Knowlton for the 

 privilege of studying it, as well as for many other favors. 

 Acknowledgement is also gratefully made for the constant in- 

 terest and encouragement of Dr. Henry B. Kiimmel, the State 

 Geologist, who has been keenly cognizant of the importance of 

 a modern treatment of the Paleontology of the State, both pale- 

 zoological and paleobotanical. The accompanying plates make 

 no pretense at completeness, but aim to show only the more char- 

 acteristic Raritan species, or forms never before described or 

 figured.
