Specimens of this Parrot vary a good deal as to the relative amount of the white 

 and blue colouring of the top of the head, the white in some specimens encroaching on 

 the blue, and in others the opposite is the case. Most specimens, but not all, have a 

 narrow frontal edge of red feathers. 



The range of C. alUfrcms is somewhat remarkable. In Mexico it is a bird of the 

 west coast from Sonora to Tehuantepec. It is absent from the Eastern States, but in 

 Yucatan it is abundant. In Guatemala, again, it appears as a western bird, with the 

 exception of the flock or flocks which frequent the hot springs situated on the road to 

 Vera Paz between the Rio Motagua and the village of Chuacus. Our skins from 

 Nicarao'ua are from the central region and Chontales on the eastern side. In Costa 

 Rica it appears to be a western bird.
