* Charadrius Jiiaticula, Scohpax gallinula, Anas querquedula, and 

 Podiceps auritus. Of those recorded by Lilljeborg and Me\es during 

 their stay at Sennaks, Ladeinopole, and \V osnesenski, Hen- Sievers 

 did not observe the following — Frinf/illa coccothraustes, Tiirdus visci- 

 vonis, Coracias yarrula, Locustella Jluciafilis, Accentor viodularis, Corvm 

 corone, Limosa cegocephala, 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. 182j these — Picus leuconotm, Podiceps criMatus, 

 and Sterna Jluviatilis. 



t Owing to an unfortunate slip in an-anging and paging the MS. of 

 Part III., the species numbered m the Table 59-73 sluudd in con-ect 

 order follow No. 42, and those numbered 4.'}-58 should be numbered 58- 

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

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