8. Thamnophilus melanurus, Gould. 

 Thamnophilus major, Tsch. Av. Consp. in Weigm. Archiv., 



1844, p. 277, et F. P., p. 170.

Long, tota 8 5, alse 3-7. caudae 3*3. 



Hab. New Granada, Bogota ; East Peru, river Ucayali 

 (Gould). 



Mr Gould's collection contains examples of this bird, which 

 differs from the preceding, in the want of the white bars on the 

 rectrices. Bogota skins and the Ucayali specimens agree in 

 this respect, though Tschudi describes his Peruvian " major" 

 as having some white spots upon the outer barb of the external 

 tail-feather. 



9. Thamnophilus transandeanus, Sclater. 

 Thamnophilus transandeanus, Sclater, Pr. Z. S., 1855 (Jan. 



23). 



$ supra niger ; subtus albus ; tectricibus alarum superiori- 

 bus et caudse inferioribus nigris albo terminatis ; cauda nigra, 

 rectricibus duabus utrinque extimis macula parva terminali 

 alba. 



Long, tota 8*1, alae 3*7, cauda? 3*2. 



Hab. Guayaquil in Ecuador (Barclay). 



A specimen of this apparently distinct species in the British 

 Museum was brought by Mr Barclay from Guayaquil, where 

 it is found in the thickets. It resembles T. major in general 

 appearance, but has the under tail-coverts black, with the ends 

 terminated with white, and wants the medial spots on the rec- 

 trices, the two outer of which only have white tips.
