dull leaden blue, the upper part of the head darker. The white spot be- 

 fore the eye is mottled with grey, the line extending over the eye obscure, 

 and the edging of the occiput faint reddish-brown. The two white marks 

 exist on the sides of the neck, but are merely edged with darker blue ; 

 there are slight indications of the white collar, and the band before the 

 wing is marked, but much smaller than in the adult. The quills are dark 

 brown, but the secondaries are not tipped with white, of which there are 

 but slight indications on the scapulars. The upper tail-coverts are black- 

 ish, the tail bluish-grey, lighter at the end. The bill is dusky, the feet 

 of a leaden tint. 



Male in the third year. Plate CCXCVII. Fig. 2. 



After the second moult, the male has greatly improved in colouring, 

 although the tints are not nearly so pure as in the old bird. The hind 

 part of the back is still brown, as are the wing-coverts ; the sides are dark 

 brownish-grey, with undulated yellowish-red bars. The white collar is 

 not yet complete, but all the white markings on the neck are edged with 

 black ; the fore part of the breast is dull grey, the middle yeUowish-grey, 

 spotted with bluish-grey. The white bar on the wing is still wanting ; 

 the rump is glossy bluish-black, the tail nearly of the same tint.
