 (Plate XVII.) 



1. ClIIROMACHiERIS CORONATA, 11. Sp. (Plate XVII.) 



Head black cncirelrd by yellow fcatbers forming; a coronet ; back, 

 tail-, and wing-coverts silky black ; wings and tail brownisb black, 

 paler internally; throat and breast black; abdomen and under tail- 

 coverts grey with a whitish spot in the centre of each feather, but this 

 can only be seen by separating the feathers ; under wing-corerts 

 white with yellow edges ; bill on the upperside black, paler under- 

 neath ; feet yellow. 



Total length 3i inches, bill 4| lines, wing 2 inches 3 lines, tail 

 1 inch. 



Ilab. Columbia. 3Ius. Boucard. 



The present bird is the seventh of this interesting genus, and 

 cannot be confounded with any of the other species. The single 

 specimen, from which the figure is taken, is a fine male, and came 

 in a large collection of birds sent from Bogota. 



2. Lampornis violicauda, var. ? 



Upper surface purplish black, lighter on the rump; tail-coverts 

 and central tail-feathers black ; lateral tail-feathers metallic purple, 

 with the tip and external edge of each feather dark blue ; chin and 

 breast black, with a line of lustrous purplish black feathers com- 

 mencing at the angle of the bill and passing down the sides of the 

 neck ; abdomen black in the centre, paler on the sides, with a line of 

 white feathers on each side as in L. violicauda ; under tail-coverts 

 purplish black ; bill and feet black. 



Total length 4 inches 2 lines, bill 9 lines, wing 2 inches G lines, 

 tail 1 inch .5 lines. 



JIab. Brasilia. 3Ius. Boucard. 



I have only one male specimen of this bird. It is closely allied 

 to L. violicauda, from which it differs chiefly in its colour. Pos- 

 sibly it may be a melanism of that species.
