Above mouse-brown ; tail blackish, outer rectrix with its outer 

 web rufous : beneath pale cinereous, belly tinged with ochraceous ; 

 under wing-coverts ochraceous : whole length 6 inches, wing 2-2, 

 tail 2-8. Female similar. 



Hah. Patagonia. 



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

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

 some of Mr. Hudson's skins with d'Orbigny's typical specimens.

Above brown ; wings blackish ; edgings of wing-coverts and a 

 band across the base of the remiges rufous; tail-feathers much 

 pointed, pale rufous : beneath wliite, more or less tinged with 

 cinereous ; small but distinct gular spot sxilphur-yellow ; flanks and 

 crissum fulvous ; bill lengthened, rather incurved : whole length 

 6 inches, wing 2-2, tail 2-8. Female similar. 



Hah. Argentina and N. Patagonia. 



This species should perhaps be placed near to ;S'. striaticeps, which 

 it approaches as regards its graduated tail and slightly incurved bill. 

 But it agrees with the last group in having a distinct gular patch. 

 In habits, according to Mr. Hudson, it resembles Limnomis curvi- 

 rostris rather than its congeners.
