money for them. He even delivered a special series of lectures on the geology and 
natural conditions of Spitzbergen and on the equipment of Arctic expeditions so as to 
prepare the members of the expeditions in the most careful way for their tasks. 
I am personally very greatly indebted to Professor Wiman, in the first place for 
the great confidence he has shown in me by entrusting to me the leadership of the 
Spitzbergen expeditions from the year 1912, and for his very obliging action in handing 
over to me the investigation of the large material of fishes. For all the kindness I have 
experienced during my work and for all the stimulus that I have received from him 
I must also tender him my most hearty thanks, but I feel especially grateful to him 
for his close personal friendship and support during the years I have had the pleasure 
and privilege of being his pupil. 
I am also greatly indepted to the friends and colleagues who accomparied me on 
the expeditions to Spitzbergen; several of them have not only been members of the 
expeditions in the ordinary sense but have at the same time helped to defray the 
expenses connected with the expeditions. The following is a list of their names arranged 
according to the expeditions in which they took part. 
1912: Lieutenant Count Hugo B.M. Hamilton, Fil.Mag.FoLKESjosTRAND, Kand. TorSjunnesson.

To Professor A. G. Hogbom, who kindly allowed me the use of a room for my 
work at the Geological Institute and who has always followed my work with interest I 
wish to offer my most sincere thanks. 
I obtained much help and good advice and information with regard to the expeditions 
from Professor G. de Geer and Dr. Bertil Hogbom, of Stockholm, whom I should like 
to thank most sincerely for their kindness. 
Through my respected teacher, Professor A. Wiren, I obtained from the collections 
of the Zoological Institute very valuable material of recent ganoids and both for this 
and for the interest he has otherwise taken in my work it is my very pleasant duty to 
tender him my very best thanks. A valuable collection of recent fishes for the purposse 
of comparison was also obtained from Docent S. Bock, whom I have also to thank for 
much good advice ad many interesting views. In this connection I should like also to 
thank most respectfully Professor G. Holm, who in the most obliging manner put the 
Spitzbergen Collections of the State Museum at my disposal. 
During our expeditions I received much kind assistance from Mr. K. Bay, Director 
of the «Store Norske Spitzbergen Kulkompani«, and Mr J. Bay, manager of the «King’s 
Bay Kulkompani», and it is a great pleasure to offer them my most sincere thanks. I 
recived great support during the expeditions from Swedish quarters as well, in the first 
place from the Isfjorden-Bellsund» Company and later in 1918 from the Aktiebolaget 
Spetsbergens Svenska Kolfalt and I must express my gratitude for this support especially 
to Director E. Kinander, Director B. Granholm, and B. Johnsson, engineer.
