2 Stetges. 



occa.sioiially tinged willi buff; primaries white on tlie inner vrebs 

 and at the base, crossed witli from six to eic;ht blackish-browu 

 bars, tlic interspaces vermicuLated with white and blaekisli-brown, 

 occasionally tinged with buff; tail feathers Avhite, occasionally 

 tinged with buff, crossed with six distinct blackish-brown bars, 

 the interspaces A"ermiculated with zigzag lines of the same colour. 

 Facial disc whitish and tinged with reddish-buff; a black spot in 

 front of the eye, ])luuies in front of it tinged with reddish-buff. 

 Frill feathers all white at the base, the tips buff, those over the 

 forehead vermieulated with white and black, and often at the 

 extreme tij) having a minute white dot, or in some instances an 

 irregular shaft line of black, the inner rows round the ears 

 altogether while, the outer ones with an irregular shaft line and 

 margin of black, the ends of the feathers being orange-buff, those 

 round the throat white tinged with butf towards the tip and 

 broadly margined with black : all the under surface of the bodv 

 white, with a slight tinge of buff on the sides of the chest and on 

 the under margin of the wing and flanks, the luider wing- coverts, 

 Hanks, and thighs, and remainder of the under surface except 

 the abdomen and under tail-coverts, marked with rather hnrge 

 spots, on the breast and chest a single spot, joined to a narrow 

 shaft line which becoming distinct, fornis a second spot on the 

 breast feathers, the tiank feathers have a narrow^ shaft line with 

 a tear-shaped, pear-shaped, hastate or sagittate spot near the tij) 

 of the feather ; tlie lowei'most flank feathers haA'c two distinct 

 spots, but on the thighs the miirking are obsolete. 



In an apparently fully adult bird from Port Essington, there 

 is scarcely a tinge of buff to be found, a mere trace on the scapu- 

 lars and upper wing-coverts, the facial disc is white with a choco- 

 late spot in front of the eye, quills white with five or six blackish 

 bars best defined near the shaft of the feather, but not extending 

 quite across the inner web, the interspaces closely vei'miculated 

 with blackish-brown and white, secondaries similarly marked, but 

 with nearly the whole of the inner webs white, on the scapulars 

 the bars become lost in the close vermiculations of black and 

 white which occu})y the greater portion of the feather, and the 

 white apical spot found on those of the interscapular region is 

 here more strongly defined and larger. The tail in this specimen 

 has only five bars and the outer feather on either side white with 

 obsolete vermiculations at the tip, and remains of three bars only 

 along the shaft line. 



A very old bird from South Australia is similar in plumage, 

 but is more or less tinged with bull' all over the upper surface 

 exce|)t on some of the secondaries and innermost primaries, and 

 on the outer tail feathers where remains of five or six cross-bars 

 are to be found, the centre tv>o and adiaccnt feathers of the tail
