j* et ad apicem latiils nigrd. 
Crown of the head and occipital tufts black ; frill black at the 
outer edge and chesnut in the centre, gradually passing into buffy 
white on the face; upper surface and wings dark brown ; scapu- 
laries and secondaries pure white; all the under surface silvery 
white, stained with brown and chesnut on the flanks; irides red ;
