representative of the three races within our limits. We therefore think it best to use 

 this name for the common Mexican bird. 



In North America T. auduboni is found from Fort Bridger southwards, Mr. Ridgway 

 having met with it in the Wahsatch Mountains, and Mr. Allen having observed it 

 breeding in the mountains of Colorado from about 8000 feet to the timber-line. In 

 Mexico it is a common species in the tablelands, judging from the number of specimens 

 sent home in collections. Prof. Sumichrast mentions it as an inhabitant of the alpine 

 region, and as common in the pine-woods of the district of Orizaba. He obtained it at 

 all seasons at Moyoapam, a locality about 8500 feet above the sea-level^. 



Its presence in Guatemala is known from a single specimen obtained in December 

 1873 in the pine-forests of the Volcan de Fuego, at an elevation of about 11,000 feet 

 above the sea. Whether the species is resident in this tract of forest or not cannot at 

 present be stated ; but it is not at all improbable that it is to be found there, as near 

 Orizaba, at all seasons. It is also almost sure to be met with in the upland ridges 

 of the Guatemala Altos which stretch north-westwards to the Mexican fi:ontier. Our 

 Guatemala bird exactly resembles Mexican examples, being fully equal to them in size, 

 and consequently considerably larger than the Vera-Paz specimen of the true T. pallasi.
