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, I), 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 Eosa 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 ^.

We only know this well-marked species from the type specimens sent us by our 

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