only from Ecuador. They have the outer tail-feathers black with a whitish 

 tip about three mm. wide and whitish margin to the outer web of the feather 

 apically. The second pair of feathers has a barely perceptible whitish tip 

 and the remaining rectrices are wholly black.

(3363) Cinnicerthia unirufa (Lafr.). 

 Limnornis unirufus Lafr., Rev. Zool., 1840, p. 105 (Bogota). 



Very common in the Temperate Zone of the Eastern Andes. This is 

 doubtless the representative of C. unihrunneus of Ecuador and the Central 

 Colombian Andes 'Bogota' specimens of which are probably from the 

 Central Andes. Old Bogota specimens of unirufa are materially paler 

 than freshly collected ones.

(3364) Cinnicerthia unibrunnea {Lafr.). 



Limnornis unibrunnea Lafr., Rev. Zool., 1853, p. 59 (Ecuador). 



Found only at Laguneta and Santa Isabel in the Central Andes. Seven 

 specimens collected at these localities agree with five recently collected 

 birds from Gualea and Pichincha, Ecuador.

V Cinnicerthia olivascens infasciata Chapm., BuU. Am. Mus. Nat. Hist., XXXI, 

 1912, 158 (Andes west of Popayan, alt. 10340 ft.). 



Inhabits the Temperate and upper portions of the Subtropical Zones 

 of all three Ganges of the Andes. Since describing a supposed form of this 

 species from the Andes west of Popayan, under the name Cinnicerthia 

 olivascens infasciata {I. c), the acquisition of additional material leads to 

 the conclusion that there is but one race of this Wren in Colombia. Un-
