4. Sycalis COLUMBIANA, Cab. ? 



Mus. Hein. i. p. 147 (Puerto Cabello). 



Angostura. A female. Not having yet seen this small 

 bird from the Orinoco, I am not quite sure about tlie cor- 

 rectness of this determination, although my bird agrees 

 tolerably well with the description given by Prof. C/abanis of 

 the female of his S. colmnbiana. 



The Angostura bird is very different from the female of 

 S. flaveoJa, not only in its exceedingly small size but also in, 

 coloration. The upper parts are of a uniform greyish olive, 

 with quite indistinct darker basal marks on the feathers. 

 Top of head and sides of head still more suffused with greyish. 

 Underparts brownish white, throat and middle of abdomen 

 purer white, breast and sides of belly marked with indistinct 

 narrow shaft-stripes of dark brown. Under tail- and wing- 

 coverts pale yellowish white, the inner webs of the wing- 

 feathers similarly edged. Wing- and tail-feathers externally 

 edged with olive-yellow. Upper mandible dark brown, the 

 lower beneath and feet yellowish.
