The middle third of the qiiills is pale rusty-coloured, and shows 

 a great amount of whitish or even clear white ; all the other parts 

 including the bill, agree in colour with S. pileata. ' 



The type specimen (locality uncertain) is an immature male 

 having the crown of the head dull blackish brown. The biU in this 

 specimen is certainly very slender aud rather long ; but the length 

 of the bill in the genus Sittella is subject to much variation, as rnay 

 be seen from the measurements given with the different species.

 upper parts of the head and nape black.
