Obn. Professor Baird, in his ' Review,' separated H. leucosticta 

 from H. proxtheleuca, but on characters which do not hold o-ood as 

 already pointed out by Mr. Salvin. The pureness of the white' on 

 the under surface or the size of the white spots on the sides of the 

 head are not characters of any great import : but the black head of 

 the South-American bird seems to me to distinguish it at a "'lance 

 Messrs. Salvin and Godman have specimens from Sarayacu Ecuador 

 (Buckleif), and from Chira, Eastern Peru {Hamrweil), which are 

 identical with Demerara skins collected by Mr. Henry Whitelv 

 excepting that one of the latter has a few white spots on the crown' 

 Cabanis's description is so evidently taken from the Guiana bird that 

 his name must be applied to the "black-headed form. '
