HALF-COLLARED DOVE. 209 



for the examples of the different ages or sexes of 

 one species. We believe, however, that they are 

 truly distinct, at least the plumage of that we shall 

 now describe shews every appearance of perfection, 

 while from the length of the wings being only five 

 and a half inches, instead of seven (as in eryihro- 

 phrys)) it is presumed this difference is not sexual. 

 The total length is about ten inches. The ground 

 colour of the upper plumage is drab-brown, nearly 

 of the same tint as the last ; but the top of the head 

 and nape, instead of being delicate French grey, is 

 of the same vinaceous as the under parts, the front, 

 as is usual in this family, being much paler ; behind 

 the nape is a semicircular black collar like the last. 

 The wing-covers are very light cinereous with 

 whitish edges, but this tint blends on the scapulars 

 into the drab-brown of the back. The under plu- 

 mage is vinaceous, palest on the chin and changing 

 into a cream-coloured white on the belly, vent, 

 thighs, and under tail-covers ; these parts being of a 

 full cinereous in the last species ; the basal half of 

 the four outer pair of feathers is deep black ; the 

 other portion is more or less white according to their 

 distance from the two central pair, which are drab- 

 brown, tinged with cinereous. On their under sur- 

 face, the terminal half of these feathers is much 

 whiter and the base much blacker. The inner wing- 

 covers, the flanks, and sides of the tail-covers, are 

 cinereous. The bill is black and the feet pale. The 

 orbits seem to be more feathered than in the last, 

 and there is no red tinge on the naked skin ; this,
