In the Siamese specimen the feathers of the back have rather broad terminal violet 

 bands which everywhere are clearly visible. The bases of the feathers are grey though 

 almost white on the lower back. The bill is very large and stout, measuiing 64 mm. in

 and until more material has been available I t hink I am justified to ref er the Siamese 

 Grows, hitherto known under the name of Corvus tnacrorhynchus Wagl. to the Hainan 

 form 



Corvus coronoides hainanus Stres.
