 kingen and of Lissieu). 



1. Local Evolution.— Continuance of Lophiodoiitida 1 

 (Lophiodon, Cliasmotherium), of Hyraeotheriidae (Pachy- 

 nolophus, Propaheotherium, and intermediate form- lead 

 ing to Lophiotherium), of Creodonta-( Kychenida' (Pro- 

 viverra), of Bodentia-Sciuridae (Plesiarctomys), of 

 Dichobunida? (Diehobune, Mouillacitheriuni), and of the 

 mesodont Primates (Camopithecus, ?Adapis). 



2. Important Migrations of Unknown Origin of the Pa- 

 laeotheriidae (appearing suddenly with their two brandies 

 Palaeotherium and Plagiolopiius), the Anchilophidae 

 (Anchilophus), the Suidae (Chceromorus, Acotherulum), 

 the Anthracotheriidae (Catodontherium n. g., forerunner 

 of Brachyodus), the Dacrytheridae (Dacrytherium), the 

 Xiphodontida^ (Xiphodontherium), the Dichodontidae (Di- 

 ehodon, Tetraselenodon, Haplomeryx), some Sciurithe 

 (Sciurus), the TalpidaB (Amphidozotherium), the Erin- 

 aceidae ( Neurogymnurus ) . 



3. North American Migrations of the Hya?nodontid« 

 and probably of the Lemuroidea-Anaptomorphida? (Xe- 

 crolemur). 



VF. Bartonian stage (calcareous deposits of St. Ouen 

 near Paris) of Sergy (Aisne), sandstones of Castrais 

 (Lautrec, Mazou, Viviers, Montespien, etc.), of Eobiac 

 (Gard), "terrain siderolithique" of Heidenheim and part 

 of those of Mormont; very small part of the phosphorites 

 of Quercy. 



1. Local Evolution.— Continuance of Lophiodontidae 

 (last of Lophiodon and Cliasmotherium), of Hyraco- 

 theriidae (primitive representatives of Lophiotherium), 

 of Palaeotheriidae (numerous parallel branches), of An- 

 chilophidae (Anchilophus), of Anthracotheriidae (Catodon- 

 therium n. g.), of Suida? (Chcrromorus, Choeropotamus), 

 of Xiphodontidae (Xiphodontherium), of Creodonta 

 (Hyaenodon), of Sciuridae (Plesiarctomys), of Adapida> 

 (Adapis).
