5-46 F. SUMICHRAST ON THE GEOGRAPHICAL 



region, that is to say near Orizaba, at about 1800 metres, and at Moyoapam, 2500 metres, 

 in the forests of pines and oaks. 



29. Dendroica olivacea. Alpine region. One of the most characteristic species of the alpine 

 region. It is there common among the forests, from a height of 1500 to that of 3000 metres. 



30. Geothli/pis speciosa. Alpine region. To this species I refer a Geothli/pis, occurring in 

 the alpine region among the mountains of Orizaba, and which belongs to the collection of 

 my friend M. Mateo Botteri. 



31. Geothli/pis poliocephala. Hot region ? Of this species I have procured but a single 

 specimen, obtained near the upper limits of the hot region, at the height of about 450 

 metres. I do not know whether it is peculiar to this region. 



32. Granatellus Sallaci. Hot region. Found in hot and hot-temperate localities. I have 

 found it at Portrero, near Cordova, a height of 590 metres. 



33. Basikutcrus culicivoriis. Temperate region. 



34. Basikuterus rufifrons. Temperate region. 



35. Basileuterus belli Temperate region. 



These three species have their maximum of development in the temperate region, but 

 they pass beyond its limits both into the hot region and into the alpine. I have seen 

 them within the lower portions of the latter region at a height of about 2000 metres. 

 These birds frequent thickets, ravines, and dark woods. 



36. Setophaga picta. Alpine region. I have only observed this species in the alpine 

 region, between a height of 1400 and 2500 metres. 



37. Setophaga miniata. Vulg. Guajolotito. Temperate and alpine regions. Common at all 

 heights between 500 and 2500 metres. 



38. Euthlypis lachrymosa. Temj^erate region. This quite rare bird seems to be fixed by 

 its own choice in temperately warm localities, that is to say, at an elevation between 500 

 and 1000 metres. Its habits are decidedly different from those of the other SctophagincB. 

 It walks rather than perches, and when running or hopping on the ground, might be taken 

 for one of the Formicariidce. From time to time it raises itself while pirouetting to a small 

 height, spreading its tail and uttering a low cry of pleasure. I have killed one of these 

 birds in the midst of an innumerable column of tepegua ants, Eciton mexicanum, upon which, 

 without doubt, it was feeding. I have procured several in the woods, covering the calca- 

 reous rocks of Penuela, near Cordova, at about 700 metres. 



39. CardelUna rubra. Vulg. Cardelin. Alpine region. This species is one of the most 

 characteristic of the alpine region. It is frequently met with there among the pine woods 

 which it enlivens by the brilliancy of its plumage and the graceful vivacity of its move- 

 ments. Common among the mountains of Orizaba, it there attains to an elevation of from 

 2000 to 3000 metres.
