neath, and quite recalls to my mind the typical examples of C. 

 dasypus from Borneo. 



The dark-breasted Japanese birds may be young birds of the

 the pair in the British Museum : — 



Male. General colour above deep blue-black, the hind neck 

 slightly varied with white bases to the feathers which show through ; 

 wing-coverts and quills black with a slight blue gloss ; lower back 

 and rump dull white and sullied with a slight wash of brown, the 

 shaft-streaks dusky and coarsely indicated ; upper tail-coverts dull 

 white, more or less washed subterminally with dull brown as well 

 as at the tips, the long coverts blue-black ; tail-feathers blackish 

 with a very slight wash of blue ; the tail very slightly forked ; crown 

 of head like the back ; lores, feathers round the eyes, ear-coverts 

 and sides of face, fore part of cheeks, and base of chin black ; 

 remainder of cheeks dull brownish white ; throat and under surface 

 of body smoky whitish ; lower abdomen purer white ; sides of body 

 and flanks smoky brown, the sides of the upper breast darker and 

 washed with blue-black ; thighs dull white ; under tail-coverts white 

 slightlj' washed with smoky brown, the shafts in all dusky and dis- 

 tinct; the long under tail-coverts smoky brown, edged with white at 

 the tips ; under wing-coverts and axillaries glossy dark brown ;
