Family ODOBENIDAE 



Genus ODOBENUS Brisson. 



1762. Odobenus Brisson^, Regni anim., ii ed., p. 30. Type. — 

 Odobenus Beisson = Phoca rosniariis Lixnaeus. 



According to Trouessart (Catal. mamni., pt. iii, p. 453. 1897) the 

 terms applied to genera by Brisson are monomial sj^ecific names 

 without status in the Linnaean binomial system of nomenclature. 

 If this view be adopted, the proper name for the present genus is 

 Rosmarus Scopoli (Introd. hist, nat., p. 490, 1777, type, Phoca 

 rosmarus Lixnaeus).
