TERTIARY MAMMAL HORIZONS. 23 



this early Oligocene stage, the eadiest edentates, pangoHns and 

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

 pean Ancylopoda, ScJiizotJicriimi priscmn. 



The lignites of Cadibona (Piedmont) were considered Upper 

 Oligocene (Aquitanien) b}' Lapparent ('85) and Weithofer, 

 but they contain a little rhinoceros with simple premolars of 

 lower Oligocene t}'pe. A portion of the fauna of Lobsaiui 

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

 Hyopotanms vclaunus and a species of rhinoceros wrongly at- 

 tributed to Accrathcrumi i)icish'mii. 



2. Stampien 



The Mid Oligocene stage is according to all authorities chiefly 

 represented by the marine phase Sables dc Fontaiiieblai ct d' 

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

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

 Gaudry because they contain AntJiracotJierium and (?) Diccrathe- 

 rimn ininiitinn. In the Paris basin are Fcrte-Alais (Seine et Oise), 

 lacustrine sands, also placed by Gaudr}' at this level ; Scllcs-sur- 

 Chcr (lacustrine limestones), also in the Paris' Basin ; Villcbrainar 

 (Molasse, Lot et Garonne). 



3. Aquitanien, Upper Oligocene 



The typical mammal deposits of this stage are the famous 

 lacustrine beds of St. Gcraiid-lc-Piiy (Allier), calcareous, with a 

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

 beds containing Anchitherium and Mastodon. 

 Distinctive t\-pes of this stage are : 



Palseoerinaceus, 



Palaeogale (and other mustelines), 



Progenetta (and other \'iverrines), 



Amphicyon lemanensis, 



Protapirus douvillei (not certainh' a tapir), 



Diceratherium minutum, 



Aceratherium lemanense, 



Anthracotherium magnum. (Lignites de Volx.) 



Anthracotherium hippoideum. (Lignites de Volx.)
