Adult. General colour smoky bro\ra, distinctly spotted with white, 

 more largely on the back and scapulars ; on the head and hind neck 

 remain traces of ashy white vermiculations, nearly obsolete or en- 

 tirely disappearing on the back, scapulars, and wing-coverts, the 

 latter being almost uniform brown, with spots of white here and 

 there ; primary-coverts uniform brown, excepting for a few white 

 mottlings at the tip ; quills dark brown, faintly mottled with 

 whitish vermiculations on the outer web ; the secondaries darker, 

 especially the innermost, which have distinct spots of white like the 

 back ; tail dark brown, the two centre feathers with a distinct spot 

 of white at the tip, and mottled with whitish vermiculations, dis- 

 appearing on the outer rectrices, which have traces of darker brown 

 bars on the inner web ; face pale smoky brown, the bases to the 

 feathers white, all the plumes round the eye dark brown ; feathers 

 of the ruff creamy white, tipped with chocolate-brown and having 

 concealed marldngs of the same, the latter disappeacing on the gular 

 feathers ; general colour of under surface smoky brown, the feathers 

 barred across with whitish, and having a distinct diamond-shaped 

 spot of white at the tip ; the abdomen and leg-feathers whitish, 

 barred with dusky brown, disappearing on the under tail-coverts, 

 which are almost entirely white ; uiuler wing-coverts and axillaries 

 whitish, barred with dull brown, those near the edge of the wing 

 nearly entirely brown, the lower series pale greyish bro-mi, like the 

 inner lining of the primaries ; bill horn-colour ; feet yellowish ; iris 

 dark brown. Total length 17-5 inches, wing 12-9, tail 7, tarsus 3. 



A similar specimen sent from the neighbourhood of Brisbane is 

 probably a male. It differs from the one described principally in 

 having more distinct white vermiculations on the upper surface, 

 forming distinct zigzag bars on the tail ; all the white terminal 

 spots are at the same time very distinct. Total length 14-5 inches, 

 wing 11-7, tail 5-7, tarsus 2-6.
