he designates as the Temperate Region. Though not quite so distinct 

 as the preceding, it is still well marked by a i^ew positive, and by 

 many negative chai'acteristlcs. The third zone, which rises west of 

 the last, to the height, in some parts, of eleven thousand six hundred 

 feet, he calls the Alpine Region. The birds resident Avithin this 

 Alpine belt correspond in their genera, and even in many of their 

 species, Avith the birds of northern North America. Some of our own 

 birds which rarely visit Massachusetts except in winter, such as the 

 Crossbill and the Pine Finch, are found there throughout the year, 

 and our conniion Robin, Turdus migrator'ms, breeds abundantly in the 

 Alpine regions of the department. 



Of the one hundred and seventy species enumerated in the list of 

 birds native to, and resident in, the State of Vera Cruz, no less than 

 forty-six are actually or nominally binls of northern North America. 

 They are distributed by Mr. Sumichr.irt, nine to the Hot, seventeen 

 to the Temperate, and twenty to the Alpine Regions. Some, how- 

 ever, are common to two, and a few to the three regions. The follow- 

 ing lists are appended by Mr. Sumiehrast to his notes of the birds 

 resident within the three several zones or regions.
