VI. Account oF EACH SPECIES. 
Genus Mints. 
Mimus is a purely American genus of the family Turdide, the species composing it 
being very widely distributed over both the northern and southern continents as well 
as some of the West-Indian islands. ‘The three closely allied species found in the 
Galapagos Islands have their nearest continental ally in Mimus longicaudus, a species 
found in Western Peru, and belonging to a section of the genus only found in the 
Neotropical Region. There can be no question that Mimus trifasciatus and its insular 
allies are strictly congeneric with the continental birds.
