Commentary on the foregoing List. 



1. Nyctea nivea. 



2. Bubo virginianus. 



3. Bubo virginianus var. arcticus, Cassin, ex Strix arctica, Sw. & 

 Rich.,F. B. A. ii. 1831, 86, pi. 30. Bartraru's name has priority for this white 

 variety of the B. virginianus, but the term maximus would cause confusion 

 with the European Bubo, besides being antedated in the genus. 



4. Syrnium nebulosum. Strix nebulosa, Forst., Phil. Trans, lxii. 

 1772, 386, 424. 



5. Undetermined ; one of the Oti, whether wilsonianus or brachyotus is 

 uncertain. 



6. Scops asio. 



7. Cathartes aura. 



8. Undetermined. This is Bartram's particular puzzle ; it is elaborately, 

 but not recognizably, described at p. 150. cf. especially Cass., B. Cal. and 

 Tex. i. 1853, p. 59, and Allen, Bull. Mus. Comp. Zool. ii. 1871, pp. 313 et 

 seqq. 



9. Cathartes ATRATUS (Bartr.) ! The name has already been very 

 generally adopted from Bartram, who fully describes the bird, with accuracy, 

 at p. 152. 



10, 11. Haliaetus leucocephalus, juv. et ad. Description, p. 3. 



12. Pandion haliaetus (carolinensis auct.). Description, p. 3. 



13. Buteo borealis.
