Genus ODOBENUS Brisson. I 
1762. Odobenus Brisson, Regni anim., ii ed., p. 30. Type.— I 
Odobenus Brisson = Phoca rosmarus Linnaeus. 
According to Trouessart (Catal. mamm., pt. iii, p. 453, 1897) the 
terms applied to genera by Brisson are monomial specific 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 Linnaeus). '
