Lower Siam seems to be the headquarters of this Cuckoo- 

 Falcon ; elsewhere in the Peninsula it is a rare winter visitor. 

 Sclater's characters hold good in the large majority of our consider- 

 able series so far as the absence of chestnut from the scapulars is 

 concerned, though one specimen from an island in Ghirbi Bay has 

 this colour very pronounced. As regards the colour of the band 

 posterior to the white breast, some birds have it black, a few almost 

 pure chestnut, while in the majority it is mixed.
