* As there is no positive date known for Shaw's plate (610) of the Mountain Sheep, that of 1803 

 being established purely upon the supposed hypothesis that the work appeared at uniformly 

 regular intervals throughout the twenty-four years of its publication (and of which there is no proof 

 whatever), there should be no hesitation in accepting Desmarest's name O. cervina for the species, 

 bestowed without question in 1804, of which Shaw's name O. canadcnsis would be a synonym. A 

 date that is well established should always have precedence over one founded merely upon a sup- 

 position.
