GROOVE-BILLED BARBUT. 167 
markably distinguish the adult state. In every 
other respect the two are precisely alike. 
The hill, 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/g ; 
wings, 4 t 4 s ; tail beyond, 2J ; ditto from the base, 
3| ; tarsus, 1. The young bird is somewhat smaller.
