TERTIARY MAMMAL HORIZONS. 23 



this early Oligocene stage, the earliest edentates, pangolins and 

 aard varks occur. Here also occurs the earliest of the Euro- 

 pean Ancylopoda, ScJiizotJicrium priscuin. 



The lignites of Cadibona (Piedmont) were considered Upper 

 Oligocene (Aquitanien) by Lapparent ('85) and Weithofer, 

 but they contain a little rhinoceros with simple premolars of 

 lower Oligocene type. A portion of the fauna of Lobsann 

 (Alsace) is parallel (Andre.e, '84) containing AntJiracotJicruini, 

 Hyopotauius vclaiiims and a species of rhinoceros wrongh^ at- 

 tributed to AccratJicriinn incisivinn. 



2. Stampien 



The Mid Oligocene stage is according to all authorities chiefly 

 represented by the marine phase Sables dc Fontaincblcii ct d' 

 Etaiiipcs (41 metres) ; freshwater parallels are as follows : the 

 Argil cs dc St. Henri (Rhone) are placed in the Stampien by 

 Gaudry because they contain AntJiracotheriinn and (?) Dicerathe- 

 riuDi luimitiini. In the Paris basin are Ferte-Alais (Seine et Oise), 

 lacustrine sands, also placed by Gaudry at this level ; Selles-snr- 

 CJier (lacustrine limestones), also in the Paris' Basin ; Villebraiuar 

 (Molasse, Lot et Garonne). 



3. Aquitanien, Upper Oligocene 



The typical mammal deposits of this stage are the famous 

 lacustrine beds of St. Gerand-le-Piiy (Allier), calcareous, with a 

 rich fauna (Filhol, '79). This directly underlies lower Miocene 

 beds containing Anchitherium and Mastodon. 

 Distinctive types of this stage are : 



Palseoerinaceus, 



Palaeogale (and other mustelines), 



Progenetta (and other viverrines), 



Amphicyon lemanensis, 



Protapirus douvillei (not certainly a tapir), 



Diceratherium minutum, 



Aceratherium lemanense, 



Anthracotherium magnum. (Lignites de Volx.) 



Anthracotherium hippoideum. (Lignites de Volx.)
