Illustration not included in supplement volume
The type of the present species still remains in my collection, and is apparently the only one yet known It belongs to the green-headed section of the genus Eucephala, has the throat and chest blue, and is further distinguished by having the under tail-coverts brown with blue centres, and the abdomen brownish black.
The locality of Eucephala scapulata is supposed to be Cayenne; but I have no certain information on this point.
The following is a copy of my original description:—
Crown of the head, back of the neck, and lower part of the back very deep dull green; throat and chest glittering greenish blue, imperceptibly passing into the dull brownish black of the abdomen; under tail-coverts brown, with a wash of dull blue in the centre of each feather, a mark of blue on each side at the insertion of the wing, forming an indistinct band across the back; upper tail-coverts bronzy green; tail steely black, rather short for the size of the bird, and slightly forked; wings deep purplish brown; tarsi clothed with intermingled greyish-white and brown feathers; upper mandible black; basal half of the under mandible fleshy, the apical half black.
Total length 3\(\frac{3}{4}\) inches, bill \(\frac{7}{8}\), wing 2\(\frac{1}{16}\), tail 1\(\frac{3}{8}\).
