This genus is more nearly allied to StenorJnjnchus than to Phoca, 

 to which the French surgeons have referred it ; but still it differs so 

 much from tliat genus in the conformation of the skull and in the 

 lobing and rooting of the teeth, that it can scarcely he left in it. 

 The latter peculiarity appears to have escaped Prof. Owen's research, 

 as in his generic character of Stenorhynchus he says, " Anterior 

 molars with one root, the rest with two roots," while in this genus 

 the three front upper molars are single-rooted, a character by which 

 it differs from all the other genera in the family.
