From 1883 C hr. Liitken began publishing yearly reports on 
Danish birds in the German periodical “Ornis“, and by himself, 
and later on by Oluf and Herluf Winge, 5 reports in all appeared. 
From 1888 Herluf Winge however proceeded to publish these re¬ 
ports in Vidensk. Meddel, fra den naturhist. Foren, i København, 
under the title of “Fuglene ved de danske Fyr“ (Birds at the Dan¬ 
ish Lighthouses), and he continued this work till 1911 when it 
was taken over by R. Hørring. These reports give full inform¬ 
ation of all the birds which rush at the lighthouses, and are sent 
in to the Zoological Museum; they further give a record of the 
less common species which have been presented to the Museum 
in the course of the year, and finally they contained an extract of 
Winge’s own observations on birds in the year in question. 
On the fauna of Greenland Winge has published the consider- 
able papers: „Grønlands Fugle“ (The Birds of Greenland) (1899) and 
„Grønlands Pattedyr“ (The Mammals of Greenland) (1902), standard 
Works in design and execution. Both contain an exhaustive account 
of all previous contributions from the discovering of the Country 
by the Norsemen, illustrate the conditions under which the fauna is 
living up there, its relation to America and the old.world a. s. f. 
Of the rest of Winge’s works I shall here only mention his 
examination of several thousands gulps of owls and other birds as 
a means of illustrating the distribution of the minor mammals in 
this country; further papers on the sand grouse in Denmark 1888; 
on birds from the Bronze Age in Denmark, and on sea mammals 
from the Tertiary period in Denmark. 
During his last years Winge prepared a complete edition of the 
separate papers which he had written formerly on the relationship 
of the mammals, revised and made up to date, and he managed 
to send out Vol. I. (360 pages) of this work which he gave the 
title of “Pattedyr-Slægter“ (Genera of Mammals); he treats in this 
volume Monotremes, Marsupials, Insectivores, Bats, and Edentates. 
Vol. II was nearly finished when death surprised him, and as a 
completely finished M.S. of Vol. III is present, the publication of 
this, the main work of his life, is only a question of time.^) 
9 The publication of this work was continued by the present author with 
the assistance of M. Degerbøl, and was concluded by Vol. III which 
appeared November 1924.
