In this species the second and third quills are about equal, and a little longer than the first, 

 which exceeds the fourth. The tail is slightly rounded, the feathers acuminate-acute. The 

 feathers of the chin and throat have each a small triangular spot, the middle of the abdomen 

 being the only immaculate region. 



In nearly all specimens there is a trace of a median light stripe on the crown, visible at the 

 base of the bill ; sometimes this being more or less distinctly traceable half way along the crown,
