WHITE-NAPED ROLLER. Ill 



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 hroad 

 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 hy the long plumes on 

 the crown ; the edge of these feathers has a pearly 

 white gloss, but 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 back, 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 carpus, 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,
