In one specimen there is a rufous tint on the upper tail-coverts ; 

 in another there are several purple feathers irregularly scattered 

 with the ordinary golden green ones on the back ; perhaps in the 

 adult bird this purple is the prevailing colour of the back. 



This small-sized species is remarkable for the shortness of its beak, 

 which is acutely pointed, and a little dilated in the middle.
