differs from that, no less than from all others yet 
discovered, by its nuchal collar. 
The general size is equal to that of the two pre- 
ceding. The front of the head, united with a broad 
stripe over each eye, is white ; there is also a small 
spot of the same on the chin ; on the nape, or ra- 
ther on the occiput, is a large transversely placed 
spot, somewhat partially hid by the long plumes on 
the crown ; the edge of these feathers has a pearly 
white gloss, hut their basal half is of the purest 
white : the crown is vinaceous red ; the upper part 
of the neck is the same ; the interscapulars, upper 
part of the hack, scapulars, and tertials, are of a 
uniform light olive ; the greater and lesser wing- 
covers are vinaceous, changing to bright lilac on the 
margin of the cubitus, and to ultramarine blue from 
the outer angle of that joint ; and this blue extends 
all round the caipus, and spreads over the spurious 
wings and all the quills : the lower part of the 
back is of the same lilac or vinaceous tint as the 
cubitus, which gradually changes on the upper tail- 
covers to ultramarine blue. The tail is slightly 
rounded, the two middle feathers being olive- 
green ; the others, are entirely of a dark ultramarine 
blue : the under plumage, from the chin to the 
vent, is uniformly of the same vinaceous, or red 
ferrugineous colour, as the wing-covers, each feather 
having a stripe of cream-coloured white down its 
shaft : under tail-covers lilac : inner wing-covers, 
vinaceous white : base of the quills, on their inner 
surface, white, faintly tinged with blue : bill black,
