Buchang'a leucogenis Wald. 



Buclianga leucof/enis Walden, Ann. & Mag. Nat. Hist. (4) 

 V. 1870, p. 219 : Malacca. 



Not common, and confined to peninsular and south- 

 eastern Siam. The northern limits of its range are stil] not 

 ascertained, but this s})ecies has been met with at Bangkok. 

 The birds from Salanga or Puket have been separated by 

 Reichenow (Nomencl. Mus. Hein. 18U0, p. G9) under the 

 name of Dicrurus leucogenis var. salangensis, but this name 

 probably only becomes a synonym of the typical form. I have, 

 however, been unable to examine specimens from that island.
