I have yet to see undoubted specimens of C. coturnix from Japan. 

 Of course, that proves nothing', for Mr. Ogilvie-Grant may have seen 

 them, but with his paper and the above-described series of specimens 

 before me I can only say in regard to the occurrence of the two species 

 in Japan "not proven." 



Concerning the exact significance of the elongated throat feathers 

 in the eastern birds, I have no well-founded theory to offer, but it seems 

 to me as if there might be only a, strong tendency toward the develop- 

 ment of a "beard" in the eastern form, with an individual variation in 

 this respect similar to the throat coloration. 



It will probably remain for the Japanese field ornithologists to settle 

 this question by the study of large series of fresh birds. 



1 hope that the above remarks may help them to fully understand 

 the issue and consequently to collect intelligently.
