JSote on the Dentition o/Hemimastodon crepusculi (Pilg.). 



Pilgrim * has described some Proboscidian teeth from this 

 locality as belonging to Hemimastodon, a new genus inter- 

 mediate between the genera Palaomastodon and Tetrabelodon. 



In the present collection are two palates and corresponding- 

 portions of lower jaws of young adult individuals, which, 

 being fairly complete except for the symphysial region 

 throw some additional light on the dentition of this o- e nus. 

 The palates show two three-ridged teeth — the first and second 

 molars — with remains of two smaller two-ridged teeth in 

 front, which apparently represent the third and fourth 

 premolars.
