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

 and tlie 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 blackish, the tail bluish-grey, 

 lighter at the end. The bill is dusky ; the feet of a leaden 

 tint. The male in the third year, and after his second 

 moult, has greatly improved in colouring, although the tints 

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

 of the neck 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 mark- 

 ings on the neck are edged with black ; the fore part of the 

 breast is dull grey, the middle yellowish-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." 



The Author was never able to obtain a specimen of the 

 windpipe of the male of this species, which is thus described 

 by Audubon :• — •" it is six inches and a half in length, has at 

 first a breadth of only three lines, but at the distance of 

 three-quarters of an inch, enlarges to four and a half lines, 

 and so continues for two inches ; it then contracts to two 

 and a half lines, and again at the lower part enlarges to 

 five and a quarter lines, and terminates in a large transverse 

 bony dilatation or tympanum, of which the length is seven 

 and a half lines, the breadth one inch two lines ; it projects 

 as usual to the left side, where it is of a rounded form." 

 Illustrations of the windpipes of both male and female birds 

 are to be found in Prof. Newton's paper already mentioned 

 (Ibis, 1859, p. 162).
