 shorter than the fifth, but much longer than the secondary quills.

 portions to the base of the bill are separated on the forehead by a very narrow interval. The 

 whitish margin to the quills is seen only on the two innermost feathers. The bands on 

 the wing cross the ends of the greater and middle coverts. The wing and tail feathers, except 

 as described, are margined with the color of the back. The back is sometimes tinged with 

 ashy. The under tail coverts are tinged with sulphur yellow. The leathers on the sides of the
