OF THE GALAPAGOS ARCHIPELAGO. 471 



VI. Account of each Species. 



Genus Mimus. 

 Mimus is a purely American genus of the family Turdidse, 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.

 to tip 131 inches, inside of mouth flesh-colour, and contents of the stomach insects."
