2. Migrations of North American, origin of Tapiridffl 

 (Protapirus, Paratapirus), and of Ainynodontid:r ( ( a-

 (Eusmilus). 



3. Migration probably from Africa (and perhaps a 

 little before the Stampian), of Edentata with normal ver- 

 tebrae (Leptomanis and Arcluroryeteropus of the phos- 

 phorite beds). 5 



4. Migrations of unknown origin of Cervulinae (Dremo-

 sorex), of Soricida 3 ( Amphisorex, Sorex), of Lutrinae 

 (Potamotherium), of the Felidae-ProaMurina* I Pseud:e-
