covered among the Rodents, and several changes of nomenclature in 

 other groups proved imperative, and have been made known in advance 

 of the publication of the completed work. The following papers have 

 therefore been the outgrowth of the present undertaking.^ 



In this connection my thanks are especially due to Dr. C. Hart Mer- 

 riam, who kindly turned over to me the whole of the Peterson Collection 

 of Mammals for elaboration ; to Professor W. B. Scott of Princeton Uni- 

 versity, at whose solicitation this work was undertaken, for superintending 

 the preparation of a large part of the drawings for the illustrations here 

 presented, and for seconding in every way my efforts to secure a satis- 

 factory presentation of the results of my work ; to Mr. J. B. Hatcher for 

 an early transcript of his field notes (since published in his narrative, to 

 which they are herein duly credited) ; to Mr. Barnum Brown, who accom- 

 panied the Princeton Patagonian Expedition of 1899, for important field 

 notes, a few specimens, and much verbal information about the country ;
