Mr. Oberholser identifies a male from Florencia as agreeing essentially 

 with a National Museum specimen from "E. Peru" which has been com- 

 pared with the type. The Peruvian specimen is somewhat faded, a fact 

 which doubtless accounts for its being slightly paler than the Colombian 

 bird. This record materially extends the known range of this recently 

 described species.

Count von Berlepsch (Nov. Zool., 1902, p. 51) has identified as Myiar- 

 chus ferox venezuelensis Lawr., certain specimens of Myiarchus from the 

 middle lower Orinoco and comparison of our specimens from the same 

 region with Lawrence's type confirms his views, so far as subspecific rela- 

 tionship is concerned, but in the absence of material I am unable to make 

 comparison with true ferox. 



I now refer to this form five specimens from Villavicencio and three from 

 La Morelia and Florencia which, although they average darker above than 

 the Orinoco birds and have the bill shorter and broader, the belly deeper 

 yellow than the type, are evidently the representatives of venezuelensis 

 which, having been described merely as from 'Venezuela,' would appear 

 to come from the Orinoco region of that country and to range westward 

 through Colombia to the Andes. The La Morelia and Florencia birds are 

 somewhat darker than those from Villavicencio. The difference is in part 

 due to their fresher plumage and is in part no doubt racial.
