described by Brisson ; it is one of the most splendid 

 of this genus, having the remarkable peculiarity 

 (which is, however, shared with the next species) 

 &f the bill possessing two distinct colours, the upper 

 mandible being of the richest crimson, while the 

 lower one is jet black. 



General plumage on the upper part of the body 

 rich light blue, excepting the head and upper part 

 of the neck, which are cinereous grey, darkest on the 

 front and crown, and gradually blending on the 

 upper neck with the blue of the interscapulars ; 

 over each eye is a greyish white line, which begins 

 at the nostrils, and terminates just above the eye ; 

 the eye itself is surrounded with a black ring united 

 to a patch of the same colour between the eye and 

 the bill ; the upper mandible appears entirely crim- 

 son, but its sides, just at the rictus, are black ; the 

 ears, sides of the neck, middle of the breast, and 

 flanks, are shaded with light cinereous, minutely 

 freckled or crossed with delicate lines and spots of a 

 darker colour : this part of the plumage is prismatic, 

 and reflects a delicate tint of green. All the rest of 

 the under plumage is white. The tail, the scapu- 

 lars, and the largest portion of the quills, are light 

 blue. The rest of the quills, and the whole of the 

 covers, are deep black ; inner wing-covers, and half 

 of the quills beneath, white ; feet, and under aspect 

 of the tail, deep black.
