Mr. Sclater’s description of this species was based upon specimens in the British 
Museum ' from Bogota; the bird has since been traced over a large portion of Central 
America and southwards to Peru’. In South-eastern Brazil a very closely allied 
species, D. mentalis, takes its place, from which it can only be distinguished with 
difficulty. The Brazilian bird, however, is yellower on the abdomen, and the white of 
the throat spreads to the breast, the latter being thus less ashy. | 
In Guatemala we found this species very abundant in the great forest region which 
spreads over the northern portion of Vera Paz into the department of Peten. It 
frequents the underwood of the forest, seeking its food near but not on the ground. 
We know nothing of the nesting-habits of this bird, but another member of the genus 
(D. unicolor), Salmon says, lays creamy white eggs sparsely spotted with small red 
spots, and with a zone of large blotches of the same colour round the middle *. 
Stolzmann met with D. semicinereus at Huambo and at Santa Rosa in Peru, at an 
elevation of 6000 feet above the sea-level. He says it is strictly a forest bird, moving 
about in small flocks either alone or with the wandering bands of birds. It flies 
usually near the ground, when it follows, like Pithys, the hordes of foraging 
ants ®.

collector Enrique Arcé from Veraguas in 1865, and described by us in the following
