2. nETEROCOEAX. 



11 



on the primaries ; tail greenish black, shaded with purple towards 

 the base ; frontal plumes and space between the eye and the nostril 

 bare, as well as a small patch at the base of the lower mandible ; 

 biU and feet black. Total length 18 inches, culmen 1-85, wing 

 11-75, tail 7-2, tarsus 2-05. 



Obs. This Rook differs from G. frucjileijus in having only the 

 frontal space and the base of the lower mandible bare, the throat 

 being feathered. In the plumage there is no contrast between the 

 head and the rest of the upper surface, the general tone of the 

 plumage being uniform purple from head to tail ; on only one spe- 

 cimen can I detect a faint shade of greenish on the sides of the 

 neck. The specimen mentioned below from Irkutsk is a much 

 blacker purple than any of the Chinese birds. The bill varies a 

 good deal in size, the Japanese birds having, as a rule, rather a 

 smaller bill than those of China. 



Hab. China and Japan, ranging into Eastern Siberia.
