Illustration not included in supplement volume
Count von Berlepsch and Dr. Taczanowski state that the specimens of Gouldia conversi from Chimbo in Ecuador differed from those from Bogota in having the elongated plumelets in the centre of the breast of a fine blue colour, more or less intense, whereas the Colombian birds have these plumelets of a bluish or golden green.
The wings are also shorter and the smaller upper tail-coverts have more of a coppery violet tint; otherwise the two forms do not differ.
