Adult in hrecding-plumage. General colour of plumage oil-green, 

 shading into dark greenish blue on the head and neck ; the wings, 

 upper back, and scapulars of a more greenish-bronze tinge, and 

 narrowly margined with very dark green. The white feathers 

 bordering the gular pouch thickly mottled with dark greenish 

 black; the head and neck partially concealed by long narrow white 

 feathers ; a large patch of white feathers on each flank. Total 

 length about 33 inches, culmen 2-5-2-8, wing 12-13, tail 5*8, 

 tarsus 2-4-2-6. 



This species is most nearly allied to P. carho, but may be distin- 

 guished at all ages by the shape of the bare space on the throat ; 

 in the present species the feathering extends forward beyond a 

 line drawn at right angles to the commissure of the gape, while 

 in P. carho the feathering does not extend nearly to this line (see 

 fio-s. 1 & 2, p. 340). The adult may be further easily distinguished 

 by the mottled feathers bordering the throat, the colour of the 

 scapulars and wing-coverts, which are greenish bronze instead of 

 bronze-brown, and the oil-green colour of the underparts. Tail 

 composed of 14 feathers. 



Bill dark horn-brown ; feet black {Temm. 4' ScJil.). 



Adult in non-breeding plumage. Kesembles the above, but the 

 white feathers on the head and neck are wanting. 



Birds in immature plumage. Closely resemble the young of 

 P. carho of a similar age, but may always be distinguished by the 

 shape of the feathering on the throat, and, in older specimens, by 

 the colour of the scapulars and wing-coverts. 



Bill yellowish horn-colour, blackish brown along the culmen, 

 and yellow at the base of both mandibles ; naked skin about the 

 face bright orange-yellow. Inside of mouth yellowish fiesh-colour. 

 Iris yellow. Legs blackish brown with a purplish tinge, claws 

 lighter {R. Swinhoe).
