302 PATAGONIAN EXPEDITIONS : ZOOLOGY 



decorated with tawny and dull buff tipping and notching to each feather. 

 Lower parts buffy of a pale cinnamon shade, decorated with striping on 

 neck and sagittate markings on the sides and flanks of deep brown. 



Head : Crown deep umber brown, the feathers bordered with creamy 

 buff, giving a general mottled or flecked appearance to the whole. The 

 crown is defined by the color of the sides of the head and face as well as 

 the nape, in which regions the buffy cinnamon prevails and each feather 

 has a median dark streak. A dusky region just in front of the eye indefi- 

 nite to the base of the bill. An almost immaculate streak of buffy cinna- 

 mon above this dusky streak is prolonged into a rather indefinite eye- 

 brow streak, which is less immaculate than in front of the eye. 



Neck : Above much like the crown ; below creamy buff, immaculate 

 on chin and upper throat, striped with median lines of umber on the 

 lower throat and with sagittate umber marks on the lower throat and fore- 

 neck. 



Back : Deep umber brown inclining to black, the feathers bordered termi- 

 nally and somewhat notched with creamy buff and light rufous shading. 

 Lower back similar in ground color, with more profuse decoration of creamy 

 buff. Upper tail coverts bordered terminally and notched at least four times 

 on each vane with creamy buff, giving a barred aspect to these feathers. 



Tail feathers barred dark brown and deep slate, bordered narrowly and 

 tipped rather broadly with creamy buff. The outer ones showing some 

 cinnamon rufous in place of the slate bars. 



Wings : The wing coverts like the back, but with paler edging and 

 notching. The bastard wing and primary coverts much less decorated, 

 being almost clear dark umber brown, with slight edgings of creamy buff. 

 The primaries are dark umber brown on their exposed surfaces, shaded 

 with greyish brown on the inner webs. The two outer ones are inimacit- 

 late and the rest of the series only just tipped with creamy buff. No 

 notch marks on the prhnaries. The first primary has the shaft clear ivory 

 white. This color is obscured on the shafts of the second and third 

 primaries and from there the shafts are deep brown. The secondaries 

 are brown notched and bordered with creamy buff giving an indistinct 

 barred effect. 



Lower parts : General creamy buff with a suggestion of cinnamon. 

 Immaculate and light on the chin and throat. Striped, on the neck, each 

 feather having a median line of dark brown. Sagittate markings of
