Mr. Stuart Haker (Bull. Brit. Orn. Club, xxxviii. 1917, 

 p. 16) has described X. flavescens vivida from Sal win and 

 Muleyit, central Tenasserim, and gives a distribution from 

 the Kauri Kachin Hills through the Shan States, Karenuee 

 and south Burma into tiie Malay Peninsula. 



We have before us Blyth's types, collected in Arakan by 

 Phayre (vide Blyth, Cat. Birds Mus. Asiat. Soc. 1849, 

 p. 210), and these we have compared and found to be 

 identical with two specimens from Loi San Pa, South Shan 

 States, collected by Bingham. Thus it seems that Mr. Stuart 

 Baker has inadvertently redescribed the typical form as 

 A'. V. vivida, and has attached the typical name to the 



• Types of the subspecies.
