BIRDS OF WESTERN COLOMBIA. 1175 



the crown dull brownish black, the hind neck only being washed 

 with chestnut, while in the male all the top of the head, from 

 the forehead to the nape, is dark chestnut- maroon. The sexual 

 differences noticed by Mr. Carriker, however, do not hold good. 

 Both specimens have the middle of the belly extensively ochraceous 

 buflf and the flanks dark smoky grey. 



This scarce species ranges from Central Costa Rica (Juan 

 Yinas) to Western Ecuador *. On the eastern (Amazonian) 

 slopes of the Ecuadorian Andes and in Peru, F. r. ruflpectus is 

 replaced by F. r. thoracicus Tacz. & Berl. t, at once recognizable 

 by its deep black pileum, I have examined one of the typical 

 specimens and an adult male from Huaynapata, both in Count 

 Berlepsch's collection.

This species, which is named in honour of Mr. W. F. H. 

 Rosenberg, of London, who organized Mr. Palmer's expedition to 

 Western Colombia, is unfortunately represented by a single spe- 

 cimen only. The type is a perfectly adult male, as shown by the
