552 F. SUMICHRAST ON THE GEOGRAPHICAL 



from having found near Orizaba the only specimens that have been brought to my 

 knowledge. 



99. Volatima jacarina. Vulg. Locito. Hot and temperate regions. Throughout the hot 

 and temperate sections as far up at least as 1300 metres. 



100. Phompara pusilla. Hot? and temperate regions. Common in the valley of Orizaba 

 to the height of 1400 metres. 



101. Chamceospiza torquaia. Vulg. GargardiUa,, Alpine region. This species is exclusively 

 confined to the alpine region, and is very generally diffused throughout the pine woods of 

 the mountains of Orizaba, of which it is resident. The limits of the zone, within which it 

 is found, are from 1500 to 3000 metres. The plumage and habits of this bird present a 

 remarkable analogy to those of the Buarremon brunneinuchus. Both are ground birds, rather 

 than perchers, and frequently meet together in the same localities. 



102. Pipito maculatus. Vulg. Ruia. Plateau and alpine region. 



103. Pipilo fuscus. Vulg. Vie/a. Plateau and alpine region. 



Both of these Pipilos are common on the plateau of Mexico, where they have their 

 principal development. They are also found, though in smaller numbers, in the alpine 

 region, from which they never come, the first below 1400 metres, the second below 1200. 

 Both birds nest on the plateau. 



Among the resident species I must also include two other species that are not exclusively 

 Mexican. 



104. Pcuccea rufceps. Temperate region, and 



105. Spizella socialis. Temperate region, which breed here as in the United States ? 

 The following are migratory species and pass the winter in the department : — 



Passerculus alaudinus. Guiraca caerulea. 



Melospiza Lincolnii. Guiraca ludoviciana. 



Coturnieulus passerinus. Cyauospiza ciris. 



Euspiza americana. Cyauospiza cyanea. 



Cardinalis virgmiauus. Choudestes grarumaca. 



ICTERID^. 



106. Molothrus mieus. Vulg. Tongonito, Enmantecado. Hot and temperate regions. This 

 species, very common and very numerous as individuals in the hot and temperate lands of 

 the department, rarely goes beyond the height of 1400 metres. Its habit of laying its 

 eggs in the nests of other birds is a fact to which M. de Saussure has already called the 

 attention of naturalists. ("Bibl. Univ. Geneve," 1858.) 



107. Sturnella — ? Vulg. Triguero, ChichUaeMa. Hot and temperate regions and plateau. 

 A species of Sturnella is very generally distributed throughout the State of Vera Cruz, where, 

 as I think I have sufficient proof, it breeds ; not having been able to satisfy myself in regard 

 to the shades which distinguish from each other the species of this form, as described by 

 authors, I only here mention it in passing. 



108. Icterus Waglem. Vulg. Calandria. Hot region. This belongs to the hot lands of 

 the department, and is quite common in the district of Cordova, to the height of about 

 1000 metres. 



109. Icterus pustalatus. Vulg. Calandria. Hot region. Belongs to the hottest portions
