APPENDIX. 



A FEW alterations and additions have become necessary during the 

 progress of the present volume through the press. 



Page 14. Corvus corax. 



Dr. Taczanowski (Bull. Soc. Zool. France, vol. i.) considers the 

 Raven of Eastern Siberia distinct, and names it Corvus coronivo.v 

 on Dr. Djbowski's authority. A specimen from the Onon river is 

 included in our series ; and I cannot see that it is in any way speci- 

 fically distinct from the common Eaven.

Page 44. Corone orru. 



Since the account of this bird was written the iluscum has ob- 

 tained, by exchange, from the Darmstadt Museum, one of the spe- 

 cimens described by Dr. Briiggemaun as C. annectens. It is a large 

 Crow of the C. enca type, but distinguished by its greater size and 

 by the more pronounced lanceolatious on the throat, produced by 

 the splitting up of the ends of the feathers. The Marquis of Tweed- 

 dale, who has seen the specimen, identifies it as true 6'. valida ; but 

 I consider that it is undistiuguishable from G. orru, to which its 

 measurements (total length 17-2 inches, culmen 2-75, wing 13-05, 

 tail 6"7, tarsus 2-2) ally it. Dr. Briiggemaun has established the 

 existence of a second species of Crow in the island of Celebes, a 

 very interesting fact. The following specimen is therefore to be 

 added : —
