The special chapter, in which Hartert's nomenclature is used, I 

 have divided into two parts for facility's sake. In the first part 

 ray Spitsbergen observations are mentioned, in the second those 

 from Northern Scandinavia. 



I wish to express my sincere thanks here to Ir. H. H. Dressel- 

 HUYs, whose kindness enabled me to be the guest of the „Neder- 

 landsche Spitsbergen Compagnie" this summer. The fol- 

 lowing notes may prove that I have been working with good results, 

 as well as with much pleasure. 



SPECIAL PART.

All observations made during my trip in Icefjord with the Oxford 

 University Expedition are signed 0. E. The birds collected by me

 Zoological Museum, Amsterdam.
