82 Mr. C. Boden Kloss on Birds [Ibis, 



Iiido-Cliina, and China, denominated G. bankiva bankiva. 

 The former is said to have the hackles more yellow and 

 more lanceolate than in the latter, in which they are 

 redder and broader-tipped ; but the main character relied on 

 for separation is that in the Indian bird the ear-lappets are 

 invariably red, while in the other they are almost equally 

 invariably white or pinkish-white {t. c. s. pp. 2, 3). 



Through lack of material I am in no position to endorse 

 or contest Mr. Baker's conclusions ; but the series I obtained 

 in Siam seems to show that the latter distinction is not a 

 good one, for I do not think we need entertain the idea that 

 the island birds are in any way distinct from those of the 

 adjacent mainland. 



I do not know of any reason for rejecting the name gallus 

 for the species ; but while there no doubt occur two distinct 

 forms of the Common Jungle-fovvl, more or less as indicated 

 by Baker, I do not employ bankiva here for the Malayo- 

 Siamese bird : this name was based on Sundanese examples, 

 and an examination of recently-collected material from Java 

 shows that there occurs in that island a very distinct form, 

 for which I think it will have to be reserved.
