latter broadly edged with olive-brown ; cheeks, ear-coverts, 

 and ill-defiued snperciliary stripe dirty white mottled with 

 sooty brown; lores dusky brown ; sides of neck and flanks 

 dirty bufiy brown, abdomen paler, under tail-coverts rather 

 darker ; under wing-coverts and axillaries olive-brown, the

 in colour. 



Plegadis guarauna. 



The description of the winter dress of this bird was 

 inadvertently omitted from my paper in ' The Ibis ' for 1911, 

 p. 340, and should be as follows: — "The adults taken in 

 Jatiuary, February and April are all assuming the winter 

 dress, the under parts apparently changing to the colour of 

 the following specimen. 



'' Head and neck streaked with white; rest of upper parts 

 including the wings as in the summer dress, but lacking the 

 chestnut on the mantle and wing-coverts ; below including 

 thighs sooty brown, strongly washed with purple-violet and 

 Avith a very slight sheen ; under wing-coverts, axillaries, 

 under tail-coverts and tail as in summer dress. 



" Birds in tirst plumage, on the other hand, besides being 

 more oily-green above, are never so strongly streaked on the 

 head, and are sooty brown below without the purple-violet 

 wash ; tlie soft parts are also duller,^' 



PVROCEPHALUS KUBINEUS. 



On again carefully examining the large series of males of 

 this species in the British Museum, 1 find there is little 

 doubt that my second conclusion ((/. 'Ibis,' 1911, p. 121) is 

 correct^ i. e. that there are three distinct plumages : — 



The first is as described, op. cit. p. 122. 



The second is a particoloured dress, with more or less ashy 

 feathering below and with an ashy crown interspersed with 

 red feathers, or with ashy tips to the scarlet crest. 



The third is that of the fully adults, which have the 

 ordinary moult after the breeding-season and again assume 

 a full dress.
