a While the only specimen from a locality south of Colombia seen by me is cer- 

 tainly not the same as the Colombian and Central American form, Hellmayr saya 

 (Verb. k. k. Zool.-bot. Ges. Wien, 1903, 211) that the latter extends as far as south- 

 eastern Peru. It would therefore appear that two forms occur in Ecuador and Peru. 

 (See also Berlepsch and Taczanowski, Proc. Zool. Soc. Lond., 1883, 564, 565, where 

 peculiarities of specimens from northern Peru are discussed.)
