THE BIRDS OF SOUTH-WEST AND PENINSULAR SIAM. 347 



Birds from Koh Lak are intermediate between the typical 

 race of Central Siam and the Peninsular form : the present series, 

 however, having fairly well-develoj)ed crests, are perhaps nearer 

 D. p. paradiseus and we have listed them accordingly, 



D. cristatellus from " the Tenasserim coast " might be either 

 D. p. rangoonensis (Gould) or the succeeding form ; but its descrip- 

 tion so closely fits birds from Central Siam that it is best ranked as 

 a synonym of the typical race.
