TWO NEW SPECIES OF FOSSIL TURTLES 

 FROM OREGON. 



BY 



O. P. Hay. 



The testudinate remains here described were collected by 

 parties under the charge of Dr. John C. Merriam during the 

 years 1899 and 1900, in the course of geological explorations in 

 the John Day basin of Oregon. The materials are quite frag- 

 mentary, and there is some question regarding the horizon from 

 which some of them were derived. Nevertheless, it seems to 

 the writer that the bones afford characters which will enable 

 future investigators, obtaining haply better materials, to identify 

 their finds. Of the remains sent me there are four lots, with 

 numbers indicating localities where collected and their place in 

 the record of the museum of the University of California, as 

 follows : 



Museum No. 2219, locality No. 909, Rattlesnake beds, Rattle- 

 snake Creek. 



Museum Nos. 2179, 2180, locality No. 815, Mascall or Rattle- 

 snake beds, Rattlesnake Creek. 



Museum No. 552, locality No. 887, Mascall or Rattlesnake 

 beds, Rattlesnake Creek. 



Museum No. 2192, locality No. 896, Mascall beds, Beaver 

 Creek, near Crooked River. 



The lots about which there is doubt are those bearing the 

 museum numbers 552, 2179, and 2180. The nature of the doubt 

 is explained in the following extract from Dr. Merriam's report 

 on the geology of the John Day basin (Univ. Cal. Bull. Dept. of 

 Geol., ii, p. 311, 1901) :
