‘“Ce groupe* je proposerai de le désigner sous le nom de Pachylemur, et j'y 
placerai le Palzxolemur betillei, Y Adapis, V Aphelotherium [Necrolemur antiquus] 
et les divers Lemuriens signalés jusqu'ici en Amérique."  (Frrnor.) 
Gervais suggested Pachylemur as a generic name for Adapis magnus Filhol, from 
the Quercy Phosphorites, France, but used Leptadapis instead. He says: ‘‘Le 
nom de Pachylemur . . . aurait pu étre employé pour le désigner, mais c'est 
le groupe des Adapis, ou Paléolemurs, que M. Filhol a... désigné par le 
mot qui vient d'étre rappelé, aussi avons-nous dü lui en substituer un autre 
. . . Leptadapis."'
