ON BIRDS FROM THE NETHERLANDS, 233 
Falco merillus (Gerini). 
18 May 1912 a young female of the merlin, pursued 
by some crows and very fatigued, was caught alive at 
Zoeterwoude near Leiden. Some days afterwards I received 
the dead bird for the collection. This is a late date for 
this species. In the Collection van Wickevoort Crommelin 
there is a specimen caught at 7 May in our country. 
Schlegel stated, that this species is observed in summer 
in the Netherlands, but as far as I am aware, in no 
collection there are specimens killed in this season. 
Stercorarius parasiticus (L.). 
I received only one example, a young male, shot 16 
September 1911 at Makkum on the coast of Friesland. 
No otber skua’s were sent to the Museum in that year. 
Larus minutus Pallas. 
In my last report I could mention twelve examples, 
sent to our collection. During the winter of 1911—1912 
I received four examples, shot 22 November 1911 on the 
coast of Groningen and 14 December 1911, 20 and 23 
January 1912 at den Helder. 
Uria troille (L.) var, ringvia Brünnich. 
Among several guillemots shot this winter near Texel 
there were only two of the ringed variety, both males, 
killed 17 and 26 January. 
Alle alle (L.). 
In the last of January and the beginning of February 
the little auk has visited our country in great numbers, 
though by no means in such numbers as it has been 
observed at that time in Great-Britain and Ireland. Nine 
specimens, 4 oo and 5 OO, were sent to the Museum, 
viz. one, caught 20 January at den Helder; two, 23 January 
den Helder; one, 29 January den Helder; one, 1 February
