Lutra Brisson = Mustela lutra 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 nomen¬ 
clature. If this view be adopted the generic name Lutra was 
first used by Erxleben (Syst. regni anim., i, p. 445, 1777, type Lu¬ 
tra mdgaris Erxleben — Mustela lutra Linnaeus).
