having the breast red instead of yellow. This difference, however, is very apparent, as may readily he 
seen by reference to the drawings of the two species. 
As already stated, this species is found in Costa Rica, the original specimens having been obtained at 
a place called San Mateo. Since that time numerous examples have been forwarded to us by our 
collector Enrique Arce, who obtained them at San Miguel de Bugaba on the slopes of the Volcano of 
Chiriqui; and, more recently still, he has procured others in the forests nearer to Panama. On the 
railway-line itself, however, it has not yet been met with, its place being apparently taken by the orange¬ 
breasted T. chionurus. 
Nothing has as yet transpired as to its habits and economy. 
The figures are life-size.
