One of Dr. Abbott's specimens is an immature male (about two- 

 thirds grown and taken at Prahmon, Trang, March 30. It is a smaller 

 edition of the adult, but the colors are paler, the forehead is green, 

 and the ear coverts black. This specimen would indicate that they 

 must commence at this locality to breed very early. 



Dr. Abbott describes the soft colors as follows: Bill black; feet dark 

 fleshy brown or leaden; iris red. 



The form ranges from the west coats of India and Ceylon eastward 

 to Assam, Burma, Yunnan, Siam, Cambodia, Cochinchina, Annam, 

 Tonkin, and Laos and southward through Peninsular Siam to the 

 Malay States. 



Robinson and Kloss '^ say that on Terutau and Langkawi Islands 

 it is very abundant during the winter months and is found sparingly 

 in Penang and extends south as far as Parit on the Perak River. The 

 young bird taken by Dr. Abbott, mentioned above, would indicate 

 that it must breed as far south as Trang, at least, and at a very early 

 date. Deignan^*' reports that a few pairs breed on Doi Sutep at 5,500 

 feet in April and then disappear. De Schauensee ^^ states that it 

 appears to be rare in North Siam. It occurs nearly all over Siam in 

 the breeding season, but just how far south it winters or how far 

 south it breeds apparently is not known. 



A related form, M. e. leschenavlti (Vieillot), is confined to Java. It 

 lacks the brown band above the black band across the chest,

Several of the above specimens are heavily washed above with 

 caerulean blue. They are in worn plumage, and I think this color is 

 due to wear. 



There are two immature specimens in the series: A male from Pran, 

 May 27, and a female from Pak Chong, May 15; they are about two-
