< We have left most of the forms of this genus under a specific name as 
in the present state of our knowledge it seems impossible to link them up any 
further. A recent occurrence of crassirastris in South-east Siam, within the 
range of eugenei, destroys our former conception of the grouping of the 
large yellow-billed forms. Robinson has united the yellow-billed robinsoni 
to glaucina {=cyanetts ) a black-billed form of the “Arrenga” section, but 
this action is open to criticism and we now feel more than doubtful about 
melanura and cyanens being forms of one species : the Sumatran form of 
cyaneus is more likely to be castaneus.
