1914] Beebe: Revieiv of the Genus, Gennseus. 307 



the most generally accepted classifications remains undisturbed. 

 My new point of view merely provides a more logical, consistent 

 basis. With its accompanying rough summary of geographic 

 distribution, I suggest the following : 



Genus Gennaeus Himalayan Terai, Assam, Burma, South 

 China, Formosa, Annam, Hainan. 



Subgenera Gennaeus 



Hierophasis 

 Genus Lophura Siam, Malay Peninsula, Sumatra, Borneo. 

 Subgenera Diardigallus 



Lophura 

 Genus Acomus South Malay Peninsula, Sumatra, Borneo. 



If echvardsi proves to occupy the same territory in general 

 with some more typical Gennaeus, I should at once remove it, 

 together with its close relation swinhoii, and give Hierophasis 

 full generic recognition. This has as many characters to war- 

 rant it as militate against it. The final settlement of its posi- 

 tion should always be consistent with the chief use of taxonomy ; 

 clarity of relationship combined with the greatest use to the 

 widest circle of workers. 



The two points which I wish to emphasize are, first, the 

 existence of two distinct types of specific relation in the family 

 of Pheasants; and second, the possible correlation of generic 

 distinction with geographic isolation. 



Part III. 



For many reasons the genus Gennaeus is the most interest- 

 ing in the family Phasianidae, and especially because of the 

 puzzling nature of many of the forms. The birds of this group 

 are commonly called Kaleege and Silver Pheasants. It will 

 result in least confusion and comply with the custom of more 

 ornithologists if the former be used as a common generic term. 



In the field, my experience with these birds extends from 

 the haunts of albocristatus in Kashmir to nycthemerus in Fok-
