458 PATAGONIAN EXPEDITIONS I ZOOLOGY. 



Tarsus, i.i. 



Color. — Head: Dull vinaceous brown, each feather with a terminal 

 margin and one or two narrow black bands ; this gives the whole head the 

 appearance of being finely mottled or flecked with dusky ; the feathers of 

 the crown and occiput are long and form a decided crest; the longest 

 feathers are darker than the rest and soft, almost filamentous. 



Neck : The upper neck is like the head in color ; this ceases abruptly 

 and definitely on the lower neck and the color of that part is brighter 

 vinaceous, each feather having a black spot near the tip. 



Back : The mantle greyish brown, with a black spot near the tip of each 

 feather, which is defined by a strong margin of rufescent brown. Lower 

 back, rump and upper tail-coverts uniform greyish brown, with a strong 

 olive tint. 



Tail : Greyish brown, with olive cast. 



Wings : The anterior scapulars like the mantle in color and marking ; 

 the longer scapulars and tertials dull brownish, edged with bright rufes- 

 cent brown or cinnamon ; upper wing-coverts olive-brown, with a greyish 

 cast ; the tips of the greater row of coverts are bright cinnamon and 

 form a defined border, a third of an inch wide, to the velvety black 

 speculum, the outer webs of a few of the inner feathers of which are 

 glossed with metallic greenish reflections ; the feathers of the speculum 

 are tipped with rufescent white, which forms a posterior border nearly 

 half an inch wide ; primaries dull olive-brown ; the under wing-coverts 

 greyish brown, except the central ones, which are white, as are the axillaries. 



Lower parts : The breast and abdomen whitish ; the breast more or less 

 tinged with rufescent or reddish brown ; each feather is barred with at 

 least two blackish bands ; that near the tip being like a spot of irregular 

 shape and the other bars hidden and hardly noticeable ; this becomes 

 obsolete barring on the belly ; the vent and under tail-coverts are dull 

 olive-grey and some of the feathers of the coverts are strongly shaded 

 with cinnamon ; sides and flanks dull olive-grey. 



Bill: Yellow, with the culmen shaded into black; the nail definite black. 



Feet: Blue lead-color. 



Iris : Hazel or carmine.
