GROOVE-BILLED BARBUT. 167 



markably distinguish the adult state. In every 

 other respect the two are precisely alike. 



The bill, although light, is remarkably large ; it 

 is of an orange colour, except the teeth and the 

 transverse grooves beneath, which are white : the 

 orbits are quite naked, and are probably red in the 

 living bird. Except an oval patch of pure white 

 in the middle of the back, the whole of the upper 

 plumage, wings, and tail are deep black, with a gloss 

 of purple ; the sides of the throat and a broad irre- 

 gular band across the breast, are also of the same 

 colour ; the ears, chin, and fore part of the throat 

 are crimson ; so also is the middle of the body, and 

 of the belly ; but on each side, beneath the wings, is 

 a large tuft of white feathers, somewhat more 

 lengthened than the others, and tinged with a deli- 

 cate sulphur-yellow; the thighs and under tail- 

 covers are deep black ; the legs are pale, and are 

 probably reddish in the living bird. 



Total length, 9 inches ; bill, from the gape, 1^ ; 

 wings, 4 T 4 ; tail beyond, 2J ; ditto from the base, 

 3J ; tarsus, 1. The young bird is somewhat smaller.
