Adult male. General colour above blue, the mantle and upper 

 back dusky blackish washed with blue : lesser wing-coverts like the 

 back ; median coverts white, forming a broad wing-band ; greater 

 coverts blackish, edged with dull blue and tipped with white ; bas- 

 tard-wing, primary-coverts, and quills blackish, edged externally 

 with blue ; upper tail-coverts rather duller blue than the rump, 

 which is bright cobalt ; tail-feathers blackish, edged with blue ; 

 crown of head bright blue, contrasting with the mantle ; lores dusky 

 washed with blue ; ear-coverts, cheeks, throat, and sides of neck 

 bright blue, as also the sides of the upper breast ; fore neck and 

 chest orange-rufous, extending down the sides of the breast, which 

 is white like the abdomen and under tail-coverts ; sides of body 

 tinged with pale orange-rufous ; Hanks white ; thighs blue ; under 

 wing-coverts and axillaries blue ; quills below dusky, whitish along 

 the inner web. Total length 5-4 inches, culmen 0-4, wing 2*9, tail 

 2*2, tarsus 0*6. 



The winter plumage of the adult male resembles the summer plu- 

 mage excepting that the whole of the brilliant colours are obscured 

 by sandy margins and tips to the feathers, which wear off as the 

 summer season advances. The white tips to the greater coverts are 

 more distinct, and the inner secondaries are edged more conspi- 

 cuously with whitish.
