' I give a description of the speeiraen mentioned by me in the Ibis, ISTfi, p. 405. Upper and 

 under surface shining grass-green, with a faint tinge of blue in the centre of the abdomen. Line 

 under the eye and ear coverts deep blue. Chin greenish-blue. Throat metallic pink. Under tail 

 coverts bright buff. Wings purpli.sh-brown. Tail liglit bronze-green, with a snbtcrniinal blackish- 

 brown bar. Bill and feet black. Total length, 4^ in. Wing, 2f in. Tail 2 in. Culmen, | in. 



Should this prove eventually to represent a distinct species, 1 would propose the name of Peta.io- 

 phora rubrigularis.
