*A few fossil forms too poorly preserved to admit of careful des- 

 cription and naming have been omitted from this list. In compiling the 

 list I have made extensive use of Matthew's Faunal Lists of the Tertiary 

 Mammalia of the West as given in U. S. Geological Survey Bulletin No. 

 361, 1909. I have made no effort on my own part to indicate the relative 

 value of synonyms where synonyms exist, but have endeavored to follow 

 closely the nomenclature as given by Matthew. For additional con- 

 venient helpful literature the reader is referred to Hay's Bibliography 

 and Catalogue of the Fossil Vertebrata.of North America, U. S. Geological 

 Survey Bulletin No. 179, 1902, and to Palmer's Index Generum Mam- 

 malium; a List of the Genera and Families of Mammals, U. S. Department 

 of Agriculture, Division of Biological Survey, 1904. 



Effort has been made to indicate the scientific paper in which each 

 form was first described and named, its year of publication, also the 

 approximate locality within the area covered by the accompanying map 

 of the Black Hills region where the earliest or type specimen was 

 found. Such reference is omitted in a few instances where I have not 

 had opportunity to examine the original publication. So. Dak. means 

 in all case the southwestern part of the state. Mauv. Terres wnere used 

 corresponds fairly well to the Big Badlands, hence refers generally to 

 fossils from South Dakota.
