* The Halichcerus antarcticus Peale, referred by subsequent authors to 

 Lobodon carcinophaga, has no affinity with it. The species is a typical Phoca, 

 closely allied to P. vitulina, and was correctly described by Mr. Peale. The 

 type specimens of skins and skull are in the Smithsonian Museum.
