b AUT. 13. — E. LONNBERG : 



The bird from Susuya is in full glossy plumage. The 

 other specimens collected in May and the one taken on June 18 

 have many bleached quills. The birds shot in the Autumn are 

 all fine and glossy. 



The young specimens collected in August are in moult, 

 showing in part new black feathers with blue gloss and in part 

 the grayish black feathers of the first plumage. 



The bill of the first noted specimen has a somewhat peculiar 

 shape, the upper mandible being a little more curved than in 

 the others. 



NiKOLSKi found this crow to be one of the commonest 

 birds in Saghalin (Taczanowski). Ijima saw them in numbers 

 in some of the larger fishing stations along the coast of Aniwa 

 Bay.

On the labels of the first mentioned pair Prof. Ijima had 

 written : " Apparently breeding in the conifer woods," which 

 fact was fully proved by the collecting of not yet fledged young 

 a few days later. 



The plumage of the breeding birds collected in May is much 

 worn and bleached, but that of the adult birds collected in 

 June is quite fresh. Tims the moulting seems to take place
