Adult in winter plumage. Similar to A. geoffroyi (see supra) in winter plumage; the brown 

 on the breast apparently more extended, meeting (or almost meeting) so as to form a 

 pectoral collar. Wizo slightly smaller; bill and tarsus nuicli shorter (18 and 33 mm 

 respectively, as against 23 and 38 mm). "Iris dark brown; bill dusky black; legs and 

 feet greyish plumbeous" (Armstrong 5). 



Summer plumage. In summer also the two s])ecies correspond. "In summer the upper parts 

 dec^pen in colour. A light rusty chestnut colour marks the upper forehead, runs 

 round the crown, and forms a broad nuchal collar extending across the breast and 

 colouring the greater part thereof. The white of the forehead is diminished in size 

 and divided in its centre by a narrow black line; a black line runs across above the 

 white over the eye to the ear-coverts, and another below the white above the bill to 

 the eye, and under it over the ear-coverts. A little whiUi oc(;urs under the eye, and 

 a little above it in the eyebrow, which is for the most part rufous" (Swinhoe 1). 



Sometimes, as Stejneger shows, the entire forehead of the male in summer is 

 black; more usually a space of white of very variable width, divided by a black line 

 is found on the anterior forehead. 



Female in breeding plumage. "Differs from the male in having the rufous parts iiuich 

 paler. The black markings on the forehead are almost absent, and under the eyes 

 and on the ear-coverts replaced by blaclush" (Stejneger 8). 



Young in first plumage. "Resembles somewhat the adults. The brownish grey of the back 

 is paler, and each feather narrowly edged witli is;ibella color, with which also the 

 lower parts are suffused; on the pectoral riigion a buffisli tinge replaces the rufous 

 collar, and the black markings are absent from the head, the cheeks and ear-coverts 

 I icing slightly dusky; forehead between the bill and eyes whitish suffused with Isabella 

 color' (Stejneger 8).

 Remark. The remiges of these Celebesian specimens killed in Febi-uaiy are in good con- 

 dition, as if the moult had taken place not very long ago. They are somewhat 

 larger than the examples measured by Dr. Stejneger and Prof. W. Blasius: 

 8 adults examined by the former had the wing 127—133 mm; but Taczanowski 

 (13) records one of 1 40 mm.
