Eighteen specimens : Bonda, La Tigrera, Don Diego, Mamatoco, 

 Fundacion, and Valencia. 



This form was described by Sclater from Santa Marta specimens, 

 but was later merged by him with true rufiventris. . Although not a 

 very strongly marked form, it may be recognized by its paler, less 

 rufescent general coloration, the back in particular being more brown- 

 ish, less grayish. Care must be used to compare specimens in the same 

 condition of plumage. 



This Tropical Zone form is restricted to the lowlands, from Di- 

 bulla on the east around to Fundacion on the west, extending back into 

 the foothills up to about 1,000 feet. It is scarcely more numerous in 

 one place than another, and is in fact rather rare everywhere. The 

 birds keep low down in the forest or open woodland, in tangled under- 

 growth and masses of vines, and are usually seen in pairs. They have 

 the curious wren-like habit of holding their long tail in a perpendicular 

 position, and twitching it up and down when they utter their weak 

 little chirp.
