A fine series of the Burmese Scarlet Minivet was collected at different parts of 

 Northern Siarn. 



As already remarked by Hartert (Nov. Zool. Vol. IX, 1902 p. 556) the second 

 primary has a red patch on the inner web, though the size of this patch varies a great 

 deal and is smallest in the specimens collected in Northwestern Siarn. These same 

 specimens have longer wing» than birds; from more southern districts, thus approaching 

 the true P. speciosus Lath. 



As seen by the measures given above the Siamese specimens agree well in size with 

 birds from Hainan, but they differ from these birds in having the central' rectrices purc 

 black on the outer web while in the Hainan birds the outer web is almost red. 



One male specimen collected at Pak Koh has, however, only the centres of the 

 middle tail-feathers black and the inner web is broadly margined. 



In the parts of the Siamese Malaya visited by the Expedition this beautiful species 

 was ne ver observed.
