Ohs. As in the case of the aUied species of Dryoscopus, such as D. 

 major and D. guttatus, there is some slight variation ; one specimen 

 from Gaboon has a whitish tip to the outer tail-feather, and this is 

 accompanied by a single white-edged secondary : these peculiarities 

 are either signs of immaturity or remains of winter plumage.
