undergone by a complete moult, as amongst the wing- 

 coverts and scapulary feathers there are numerous young 

 feathers making their appearance which are entirely blue 

 (see also Oates, Fauna Brit. Ind. Birds, II, p. 43). — Iris 

 blood-red, in the young specimen dark brown, bill black, 

 feet dark gray. The breeding season seems, according to 

 the above mentioned young bird, to be in Marcb and April. 

 Hab. From Tenasserim through the Malay Peninsula to 

 Sumatra and Borneo, on which latter island it is widely dis- 

 tributed and an inhabitant of lower as well as mountainous 

 countries. The Leyden Museum is in possession of speci- 

 mens from Java and Timor. On the Natuna Islands this 

 species seems to be represented by a somewhat different 

 form, Philentoma dubium Hartert.
