 small points on its anterior border, as in C. eldi. 



M. 2307. Base of an antler with numerous small points on the 

 anterior border of the beam, which may belong to the 

 same species as the preceding. 



41834 d. Terminal portion of the beam of an antler. The beam is 

 much curved, and terminates in a simple fork, as in 

 C. eldi. 



M. 2308. Terminal portion of the beam of a very similar antler, 

 but with less curvature. 



M. 2309. Base of an antler belonging to a type allied to the pre-

 the brow-tyne. 



Some of the following specimens may belong to the present species.
