Hum marginibus externe rufescentibus ; long, tota 6, alee 2*2, 

 caudce rectr. med. 2 - 8, ext. 1"8. 

 Hab. Rio Negro of Patagonia {D'Orb. et Hudson). 

 This is a peculiar species, with the tail (comparatively) short, and 

 the rectrices broad and rounded at their ends. I have compared 

 Mr. Hudson's skins with D'Orbigny's typical specimens.

 Hab. Chili, near Valparaiso, East Falkland, and valleys of southern 

 Patagonia {Darwin) ; Chili {Reed). 



In my American catalogue I gave "Bolivia (Bridges)" as a 

 locality for some examples of this Synallaxis. I have now no doubt 

 that these skins were really from Chili, as they agree exactly with 

 others received from that country, and I have found other Chilian 

 skins of Bridges marked " Bolivia."
