To hand are two adult male skins without lilac napes, and 
dated loth and 26th March, 1900. One of the specimens has a 
single lilac feather beneath the dull grey plumage. The same

bill (except at extreme point) uniform dark brown ; wing 6.5 
inches. 
[Irides bluish-grey ; bill dark brown, tip horn colour.]
