No. 1198, Halitherium Schinzi, Kaup. 



Skull and Lower Jaw. The 

 close relationship between this herbi- 

 vorous cetacean and the riving Dugong 

 and Manatee is very clearly shown by 

 all the bones of the skeleton, but espe- 

 cially so in the bones of the head. We 

 have here the broad flat frontal, the 

 short, stout zygoma, and the suddenly 

 down-curved preniasillaries, of the modern Siren representative. This specimen, 

 from the Miocene beds of the Rhine Valley, is part of an entire skeleton in the
