the possibility of intermediate links being found, bat I think it safer for 

 the present to keep the two species separate, and would at the same 

 time call attention to the apparently proportionally shorter tail of the 

 Indian birds. 



In regard to the entirely gray backed Chinese specimens, I am uncer- 

 tain whether to refer them to a separate subspecies or not, but not know- 

 ing the relative abundance of those with a pure gray back and those 

 which have the interscapular portion slightly tinged with yellow, nor 

 having any reliable information whether the two forms have a separate 

 range of distribution, I shall refer them all to P. commixtus. 



1 have no hesitation in referring the Liu Kiu bird to this form in 

 spite of the fact that I have only one specimen, for Mr. Pryer, in letter 

 dated March 10, 1887, kindly informs me that his specimens of Panis 

 minor from Liu Kiu have "less green on the back than Japanese" ex- 

 amples.
