This series agrees with Gyhlenstolpe's diagnosis of the 

 bird from northern Siam, except that the general colour is 

 not paler than in a recently collected topotypical series of 

 O. a. aureus Horsfield from Java. The tail is of fourteen 

 feathers and the second primary between the fifth and 

 sixth in length in all cases. In only two birds is the fourth 

 primary longest, three having the third longest and one 

 having the third equal to the fourth. In six adult Javan 

 birds five have the fourth longest and one has the fourth 

 equal to the third. 



We have placed our series under Gyhlenstolpe's name, 

 but we have grave doubts if the subspecies has any real 

 existence.
