* Charadrius hiaticula, Scolopax gallimda, Anas querquedula, and 

 Podiceps auritus. Of those recorded by Lilljeborg and Meves during 

 their stay at Sermaks, Ladeinopole, and Wosnesenski, Hen* Sievers 

 did not observe the following — Fringilla coccothraustes, Turdus visci- 

 vorus, Coracias garrula, Locustella Jluviatilis, Accentor modularis, Coi-vtis 

 corone, Limosa (sgocephala, Ardea stellaris. On the other hand, he 

 adds to Kessler's list of the birds of the Government of Olonetz (vide 

 * Annals,' Sept. 1877, p. 182) these — Picus leuconotus, Podiceps cristatus, 

 and Sterna fluviatilis. 



t Owing to an imfortunate slip in arranging and paging the MS. of 

 Part III., the species numbered in the Table 59-73 should in correct 

 order foUow No. 42, and those numbered 4.3-58 should be numbered 58- 

 73. To avoid further confusion, however, I think it is better now to 

 retain the order as given in Part III., erroneous though it be.
