General coloiir of the upper parts an almost uniform olive-brown, 

 occasionally inclining to russet-brown ; lores brown ; inner webs of 

 quills and tail-feathers brown. Underparts, including the ear-

 into nearly white on the centre of the chin, throat, and belly ; 

 under tail-coverts white, occasionally stained with buff; inner 

 margin of quills pale biiffish brown. Bill orange. Wings with the 

 fourth, fifth, and sixth primaries nearly equal and longest, second 

 primary equal to the ninth or tenth, bastard primary 0'95 to 0'9

Nothing is known of any differences in the colour of the plumage 

 which may be attributable to age, sex, or season. 



The Yenezuelan Thrush-Robin is confined to the mountain-ranges 

 of Caracas, where it is supposed to be a resident. 



The British Museum does not possess an exanple of this species ; 

 but skins are in the collections of Dr. Sclater and Messrs. Salvin and 

 Godman. 



[Catharus frantzii and Catharus alticola.] 



I do not think that ornithologists have done right to divide these 

 forms into two species ; but, in deference to the opinion of ornitho- 

 logists who have made a special study of Neotropical birds, I admit 

 them to specific rank, though the same principle carried out in the 

 allied genera would greatly increase the number of recognized species.
