DESCRIPTIONS OF SEVEN NEW RABBITS FROM 

 MEXICO. 



BY E. W. NELSON 7 . 



The Biological Survey Collection contains several hundred 

 specimens of rabbits from Mexico, including representatives of 

 all the species known to occur in that country, outside of Lower 

 California. Recent examination of this material shows that in 

 addition to the known species it contains the two strongly 

 marked new species and five new subspecies which are described 

 below. I am indebted to Dr. C. Hart Merriam, Chief of the 

 Biological Survey, for the opportunity to study this material, 

 and to Mr. Vernon Bailey for suggestions regarding the species 

 found along the boundary line, with which recent study has 

 made him familiar. I am also under obligations to Mr. Gerrit S. 

 Miller, Jr., Assistant Curator of Mammals, U. S. National 

 Museum, tq Dr. J. A. Allen, of the American Museum of 

 Natural History, and to Mr. Outram Bangs, of the Museum of 

 Comparative Zoology, for the use of material from the collections 

 in their charge for comparison.
