Remarks. There is but one specimen in the collection ; in the 

 section {Planesticus) which this species comes under, the sexes do 

 not differ. 



In the distribution of colors on the under plumage, it is much like 

 T. albiventris, but the color of the breast and sides is darker, and 

 the upper plumage is of a much deeper and richer brown. The 

 strong black bill is a striking feature.
