12 EMYSOREGONIENSIS. 



Geographical Distribution. The only locality at present ascertained of this 

 animal is the Oregon river, and even there it is not abundant. 



General Remarks. The Emys oregoniensis was brought from beyond the 

 Rocky Momitains by Mr. Nuttall, an ardent naturalist and excellent botanist. 

 He informs me that it is the only species of Emys he observed during a long 

 journey, from the western border of the Rocky Mountains to the Pacific Ocean. 

 Dr. Harlan first described this animal from the specimen now in my possession, 

 under the name it here bears.
