XIII. CORRECTION OF A GENERIC NAME. 

 By O. a. Peterson 



Eotitanotherium, a New Generic Name to Replace Diploceras 

 Peterson. (See Annals Carnegie Museum, Vol. IX, Article 2; pub- 

 lished August 17, 1914). 



In my article entitled " A New Titanothere from the Uinta Eocene " 

 I employed the generic name Diploceras, having overlooked the fact 

 that this name is already pre-occupied, having been employed by 

 Conrad as early as 1844 to designate a genus belonging to the Mol- 

 lusca. For this name I now substitute the name Eotitanotherium, 

 which, after a diligent search of the literature, I believe is not pre- 

 occupied. 



O. A. Peterson.
