I have compared these examples with thirty-five others 
in the National Collection, from Colombia, Guiana, and 
Brazil, and find that they differ slightly in having the entire 
upper surface rufous olive-brown, brighter on the wings, 
while the under parts are slightly more rufous. They do 
not shew any tendency to the grey on the head, hind-neck, 
and upper tail-coverts seen in the majority of the series 
mentioned above. * I do not, however, regard these minor 
details as of specific value, and have followed Dr. Ihering 
in placing T. metalophonus Bertoni, as a synonym of the 
present species. 
Tw r o eggs, collected on October 27, 1903, are bluish-white, 
blotched and spotted with pale chestnut over the entire 
surface. In one of the specimens the chestnut is confluent 
at the larger end. Axis 1*1 inch ; diameter O'75.
