The plumage changes of this species are complicated and little 

 understood. A very old male from Tasan, 28th March, has the 

 whole upper surface blue, the primaries black, edged with blue, the 

 tail glossy black, and the under surface pure white with a black patch 

 on each side of the breast. 



Another male from Hat Sanuk, 13th April, has the upper sur- 

 face blue, the primaries and primaries coverts brown, the tail brownish 

 with a blue gloss, the under surface white and the flanks fuscous. 

 Another from the same locality, dated 18th April, is similar, but has 

 the lower back brownish and the flanks more fuscous brown. Young 

 birds have the primary coverts tipped with rufous brown, and young 

 males have the rump blue at an early age.

 serim, Hume recorded some from the south as saularis and others 

 from the same district as 'inusicus. He points out, howevei', that in 

 neither case are the specimens really typical and considers that true
