310 Obituary. 



Together with Prof. F. Nanseii he collaborated to work 

 out the birds obtained by the former during Ids celebrated 

 North Polar Expedition of 1893-96; while perhaps his most 

 important work was on the Fishes of the Norwegian North 

 Atlantic Expedition, published in 1880, and on those obtained 

 by Prince Albert of Monaco on his yachts 'I'Hirondelle ^ 

 and ' Princesse Alice,' published in 1896. His last years 

 were occupied in finishing his large work on Norwegian 

 Mammals, which was only completed last year. 



Collett had many friends in England, which he visited 

 several times, and where he was much beloved. He was full 

 of sympathy and kindness, and always ready to help and 

 encourage younger men and to put himself at the disposal 

 of any who sought his advice or help. 



He was elected a Foreign Member of the B. O. U. in 1873, 

 and in 1890 was promoted to the list of Honorary Members. 

 His contributions to the pages of ' The Ibis ' are as follows : — 



" On Lanius excuhitor and Lariius major ^ Ibis, 1886, 



pp. 30-40.

For some of the facts on which this memoir is based we 

 are indebted to Professor Nansen, who kindly sent us some 

 notices of Prof. Collett from the Norwegian newspapers, and
