'^ ad. — Very similar to M. r. rubratra, but distinguishable 

 from it by the wing and tail being shorter and smaller, by the tarsus 

 being in avarage shorter, and by the scarlet colour being less distinct 

 and faintly tinged with vermilion. It also differs from M. r. wctino- 

 rei from Ruk, by the longer bill and shorter wing and tail, and by 

 the colour of body which incline towards being vermilion.
