are at once distinguished by the beautiful reddish tinge 

 of the nape and under part of the head. At this age 

 the front of the forehead is whitish. The reddish 

 brown feathers on the nape and upper part of the head 

 have in the centre a longitudinal marking of blackish 

 brown, larger on the middle feathers of the nape. The 

 moustache is rather large but neatly defined. The 

 feathers in the auditory region of a whitish tint 

 strongly approaching to reddish yellow, have longitudinal 

 dark markings, which nearly conceal the ground colour. 

 Eyelids surrounded with black feathers, and a badly-

 of a bright bluish grey colour, which take the form of 

 bands on the scapularies, greater coverts, secondaries, 

 and rump, but disappear on the lesser wing coverts. 

 The colour of these bands is bright upon the back 

 and rump, but of a marbled brown on the other parts, 

 growing of a redder brown towards the anterior ex- 

 tremity of the wing. The primaries, with the exception 

 of the light spots on the inner barbs, are blackish 

 brown. The ground colour of the tail is paler than 

 that of the wings, and broken by a dozen transverse 

 bands of a dirty white colour, shaded with grey brown; 

 the tip of the tail is whitish. The lesser wing coverts 

 are marked by longitudinal dark spots, and inferiorly 

 with orbicular whitish spots: upon the greater coverts 

 these markings assume the form of transverse bands. 

 The prevailing colour of the inferior parts is white, 

 more or less strongly shaded with pale reddish yellow. 

 The chin, throat, and sometimes the crop, are of a
