Note 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 PaJceomastodon and Tetrahelodon. 



In the present collection are two palates and corresponding 

 portions of lower jaws of young adult individuals, which, 

 being fairly complete except for tlie symphysial region 

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

 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.
