AUTOMOLUS. 157 
This bird is found in the highland forests of Vera Paz in Guatemala, and at a lower 
elevation where these blend with the forests of the lowlands to the northward. 
Comparing specimens from Vera Paz with others from the Volcanoes of Agua and 
Fuego, we find sufficient difference to separate them; the former being rather darker 
than the latter justifies this subdivision, though the difference is much less than that 
subsisting between the Vera Paz birds and the true A. rubiginosus or any of the 
other forms. 
The first example of this bird sent to Europe was probably that received by Strick- 
land from his correspondent José Constancia?; that in the late Sir W. Jardine’s 
collection? being most likely from the same source. Skinner subsequently sent 
others from the same country 4, and we found the bird not uncommon in Vera Paz.

Comparing our series of specimens from the forests of the volcanoes bordering the 
Pacific coast of Guatemala with others from Vera Paz, we find that the former are 
decidedly paler, more fawn-colour beneath, and with the back umber rather than 
rufous-brown, differences sufficiently marked to render their separation necessary. 
The species is not rare in the upland forests of the great volcanoes of Guatemala 
from an elevation of about 2500 feet to as high as 7000 or 8000 feet above the sea. 
Our specimens were all obtained on the slopes of the Volcanoes of Agua and Fuego, 
but Mr. Richardson has recently sent us two examples which he shot in the department 
of Quezaltenango, on the slopes of the Volcan de Santa Maria.
