It is said to differ from ^githina tiphia in having a larger 

 beak, more rounded wing, greyish-green head and neck, and 

 whitish throat. It has remained unique since its first 

 description. Careful comparison of the above series with a 

 large number of skins from the Malay Peninsula and Penin- 

 sular Siam reveals no material differences, and, as Oustalet 

 himself is inclined to suggest, we are disposed to think that 

 j3£. philipi must have been founded on a depigmented and 

 abnormal individual. Similar cases of abnormal coloration 

 occur not infrequently among species of green Pigeons 

 {Osmotreron and Cr'ocopus).

These three specimens, though they have not developed the 

 black wings and tails of fully adult birds, can be separated 

 from birds from the Malay Peninsula in a similar stage of 

 plumage by the much lighter greenish-yellow tinge of the 

 upper surface. Forehead and superciliaries bright lemon- 

 yellow, ear-coverts pale yellow. The birds from eastern 

 Siam listed by one of us (supra) are intermediate, but on the 

 whole are much closer to ^. I. lafresnayei than to A. I. xan- 

 thotis, which is based on a single female from Cambodia.
