 near Seoul in winter.

Six adult males were collected at Hokuryö, Mukden, May 5. In 

 that locality this species was seen nesting together with C . neglectus. 

 I have seen on May 7 a group of this bird at Hoshigaura, near Daini. 

 It seems probable that in Corea this species is found during winter 

 only, like the preceding rook. 



179. Colceus neglectus (Schlegel). 

 Tö-garasu.

Three adult 'males and one adult female were obtained at Hokuyrö, 

 Mukden, May 5. I am inclined to think that this species or form is 

 merely a melanistic form of C. dauricus, in agreement with Dr. 

 Hartert's opinion and contrary to Salvadori's. I have observed that 

 this black bird is much less numerous than the preceding species in 

 all parts visited by me of S. Manchuria. Moreover, I have always 

 seen this bird in associative with C. dauricus.
