much in evidence wherever it occurs. It frequents forest-clearings and open pine-clad 
savanas like those of Poctun in the district of Peten, and flies in pairs or a number of 
pairs together. In Honduras and Nicaragua Ara macao seems to be very abundant, as 
testified by G. C. Taylor’, Leyland 24, Nutting 12, and Richmond !’; the last-named 
collector found two eggs in a tree which he cut down in February. In Costa Rica 
it appears to be equally common, and we have specimens-from the Line of the Panama 
Railway, where it occurs with Ara chloroptera.

This Ara closely resembles A. macao in general coloration, but on examination may 
readily be distinguished by the median wing-coverts being green instead of chrome- 
yellow, the darker tint of the red colour, and by the naked cheeks being traversed by 
narrow lines of scarlet feathers. 
It was not until 1859 that this Macaw was definitely separated from Ara macao by 
G. R. Gray}, who gave it the name it now bears. It had previously been called by 
names strictly applicable to the allied form, as shown in Count Salvadori’s recently 
published Catalogue ¢. 
Its range, though apparently equally wide as that of A. macao on the South- 
American continent, is much more restricted in our country and it has as yet only been 
found on the Isthmus of Panama along the Line of the Railway. It is true that it has 
been reported from Guatemala, but we should like further evidence before admitting 
its existence so far north.
