63. CORVUS DAURICUS. 



(PALLAS'S JACKDAW.) 



Coitus dauuricus, Pallas, Eeise Russ. Reichs, iii. p. 694 (1776). 



Pallas's Jackdaw is about the size of its British representative 

 (wing 9^ to 9 inches) , but it has a white collar round the neck ; the 

 breast, belly, and flanks are white, and the bases of the feathers of 

 the mantle are dark grey. 



Figures : Temminck and Schlegel, Fauna Japonica, Aves, pi. 41. 



Pallas's Jackdaw appears to be a rare bird in Japan, and is confined 

 (so far as is known) to the extreme south. I have never seen a 

 Japanese example except those obtained by Dr, Siebold, probably 

 near Nagasaki, and now in the Leyden Museum. It is said to have 

 occurred near Yokohama (Blakiston and Pryer, Ibis, 1878, p. 232). 



The range of Pallas's Jackdaw extends from Eastern Siberia to 

 North China and Eastern Mongolia. 



64. CORVUS NEGLECTUS. 

 (SWINHOE'S JACKDAW.) 



Corvus neglectue, Schlegel, Bijdr. Dierk. Amsterd., fol., art. Corvm, p. 16. 



Swinhoe's Jackdaw very closely resembles its British represen- 

 tative, but its belly is dark grey instead of greyish black, and the 

 first eight secondaries are nearly equal in length. 



Figures : Temminck and Schlegel, Fauna Japonica, Aves, pi. 40. 



Swinhoe's Jackdaw is a rare bird in collections. The only 

 examples which I have seen from Japan are the types obtained by 

 Dr. Siebold, presumably near Nagasaki, and now in the Leyden 

 Museum, and an example from Osaka in the extreme south of 

 Hondo, and now in the Hakodadi Museum (Blakiston and Pryer, 

 Trans. As. Soc. Japan, 1882, p. 143). The latter specimen is paler 

 on the underparts than typical examples in the Swinhoe collection 

 from China, and resembles an example in the same collection from 

 Shanghai, which Swinhoe regarded as a hybrid between Corvus 

 dauricus and Corvus negledus (Swinhoe, Proc. Zool. Soc. 1871, 

 p. 383). 



The range of Swinhoe's Jackdaw extends from Eastern Siberia to 

 North China.
