All these skuLLs, of which the habitat Ls certainly known, come 

 from the west coast of America. The compression of the front of 

 the lower jaw and its small size, especially of the one from Pata- 

 gonia, shows an affinity to Otaria idloce ; but it has the short wide 

 curved lower jaw of Otaria jubata, and may be a species of which 

 the adult is not known.
