BIRDS FROM SIAM AND THE MALAY PENINSULA 519 



male at Trang, January 21, 1899. He gives the soft parts as: Iris 

 grayish brown; upper mandible black, lower mandible leaden; feet 

 leaden. 



In addition to the above, I have examined only one male from 

 Borneo and one from Sumatra; they do not seem to differ materially 

 from Peninsular Siamese birds. 



One of the males collected by Dr. Smith at Bangnara (no. 307436) 

 and another male from Bukit are passing from an immature plumage 

 into that of the adult and have almost completed the change; the 

 Bangnara male is in a more advanced state than the other. In the 

 Bukit male the upperparts are changing from a plumage similar to 

 that of the female to the blue back of the male and the process is 

 about half completed; the wings and tail are like the adult female; 

 the red crown spot is appearing; below, the yellow of the adult has 

 appeared, but the color is not so bright; the scarlet chest spot is ap- 

 pearing but is barely indicated. The Bangnara male is just farther 

 advanced; there are only a few feathers of the immature plumage 

 remaining; the scarlet crown patch is like that of the adult male; 

 below^ it is like that of the adult male but is not so bright, nor is the 

 scarlet chest spot so large. This Bangnara male has some white 

 feathers over the right eye, but there are none on the left side. 



One of Dr. Abbott's specimens from Trang is still younger (no. 

 169944, January 21). It is like the adult female, but there are a few 

 blue feathers appearing on the upper back and rump and there is no 

 indication of a crown patch; below it is like the adult female, except 

 it is not so yellowish especially the throat. There is no sign of the 

 scarlet chest spot. 



Robinson and IQoss ®^ record a male from Tasan, Chumporn, 

 Peninsular Siam, and say that it is the northernmost specimen re- 

 corded. De Schauensee ^^ lists it from Nakon Sritamarat; Baker ^' 

 from Tung Song; Ogilvie-Grant ^ from Patani. 



The form ranges from southern Tenasserim south through Penin- 

 sular Siam to the Malay States, Sumatra, Borneo, Natuna Islands, 

 and probably other nearby islands of the China Sea.

Dr. W. L. Abbott collected an adult male at Tanjong Silantei, east 

 coast of Johore, July 26, 1901. He gives the soft parts as: Iris red; 

 bill black; leaden beneath at base.
