APPENDIX A. 



SYNOPTICAL LIST OF THE EXTINCT RODENTli OF NORTH 



AMERICA. 



Bv J. A. Au.EN. 



The following list is intended to inc'ude all of the extiuct Rodentia of North 

 America described prior to 1877. The Sciuromorphs, Hystricomornhp, and LeporidiB, 

 having been nearly all noticed at some length in the preceding payes of the present 

 series of monographs, it is deemed suflBcient in the present connection to cite ihe 

 earlier pages of the present work, wherein they are more fully noticed. In respect 

 to the others, references are here given to the papers and works wherein they were 

 originally described or subsequently noticed, together with short notices of their lead- 

 ing characteristics so far as they are at present known. With our present imperfect 

 knowledge of the extinct forms here enumerated, it is impracticable tt attempt any- 

 thing more than a compilation of the species as described by authors.
