All tliese specimens show evidences of molt in both quills and con- 

 tour feathers. They bear out the distinctness of the Natuna Islands 

 race from typical Alcippe cinerea of the Malay Peninsula. The 

 upper parts are paler, more refuscent, and the occipital black patch 

 is more brownish. 



Measurements are given in Table 24.
