At the conclusion of the conjoint dinner of the B. O. U. and 

 B. O. C, the President of the British Ornithologists' Union 

 proposed the health of His Majesty the King and that of 

 absent " Ibises," as is customary at the annual dinner. 

 He then vacated the Chair in favour of Dr. P. L. Sclater, 

 who, as Chairman of the B. O. C, conducted the business 

 during the remainder of the evening : — 



Mr. W. Eagle Clarke showed a female Sanderling 

 {Calidris arenaria) and her four chicks, taken at Prince 

 Charles Foreland, Spitzbergen, in the summer of 1906 by 

 Dr. W. S. Bruce, and presented by him to the Royal Scottish 

 Museum. Mr. Clarke remarked that although the eggs of 

 the Sanderling had been known for about 85 years, the 

 chicks were rare and, so far as he was aware, had not hitherto 

 been described.
