Costa Eica and the State of Panama to Western Ecuador. In Colombia a small form 

 again appears which may or may not be the same as that of Mexico. The only southern 

 specimen accessible to us is even smaller than any of our series from the latter country, 

 so that we do not feel in a position to decide this question. Mr. Ridgway also writes 

 to say that a trade-skin from Bogota in the United States National Museum is also 

 very small, and he, in fact, was the first person to draw our attention to the point. 

 Should this southern bird be found to be sufficiently distinct for separation it will be 

 somewhat difficult to say whether the Mexican or the southern bird should bear 

 the name Ara militarise but it will be advisable to continue its use for the northern 

 form. 



We have no special account of the habits of this species, which Mr. Richmond'' 

 says resemble those of Ara macao. He adds that the naked skin on the head is pale 

 carmine-purple, the iris dark yellow, but varying in different individuals. A specimen 

 from the Rio Nercua, obtained during Lieut. Michler's expedition to Darien, and now 

 in the United States National Museum, was obtained in the cordillera in which that 

 river takes its rise ^.

 Of the presence of this Ara within our region we have only two records— a specimen 

 having been sent by M'Leannan to Lawrence ^ in one of his earlier collections from 

 the Isthmus of Panama, another was obtained during Lieut. Michler's expedition 

 to the Isthmus of Darien 3, No Central- American example has reached our hands. 

 On the continent of South America A. severa has a wide range over the eastern slopes 

 of the Andes from Colombia to Bolivia, and is found throughout the Amazons Valley 

 and in Guiana, though we have seen no specimens from the latter country 6.
