Zool. Soc. Lond., 1858, 67 (e. Ecuador). 
@ 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 says 
(Verh. 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 Ecuadér and Peru. 
(See also Berlepsch and Taczanowski, Proc. Zool. Soc. Lond., 1883, 564, 565, where 
peculiarities of specimens from northern Peru are discussed.)
