shot from a party of four on July 26th, 1911, at Crurie ; 

 that the American Blue-winged Teal, shot at Upper Nithsdale 

 in 1858 and now in the Royal Scottish Museum, is a female 

 and not a male, as has been generally accepted ; that a pair 

 of Turtle-Doves were obtained in May, 1909, in the county, 

 and a single bird in October, 1910, a Spotted Crake in August, 



1910, a Ruff in September, 1911, while a pair of Green 

 Sandpipers were seen in August, 1911. H.F.W. 



Bird- Marking in the Netherlands. By Dr. E. D. van Oort. 

 (Note XII., of Notes from the Leyden Museum, Vol. 

 XXXIV.) 



The Museum of Natural History at Leyden, we are glad 

 to learn, has started this year (1911) a " marking scheme." 

 The smaller rings are lettered leFden and the larger ones 

 ^EmEN. HOLLAND aud all are of course numbered. More 

 than 2,500 rings have been issued, and some 1,165 used 

 on thirty-one species. The reported recoveries are at 

 present naturally few in number. 



Of 160 Wild Ducks {Anas hoscas) " ringed," six were 

 reported from August to October^ all in Holland except one, 

 which was found near Dunkerque, north France, on October 

 5th, having been " ringed " in Zeeland on July 28th. 



Eighty-four Herring-Gulls {Larus argentatus) have been 

 " ringed " and two recovered ^ one in south Holland and 

 one which was " ringed " in north Holland on July 2nd, 



1911, at Margate (Kent), on October 25th. Dr. van Oort 

 remarks that, " the Herring-Gulls bred in the Netherlands 

 seem to visit the coast of S.E. England " ; but to this statement 

 we very strongly object, as being founded on entirely insuffi- 

 cient evidence. Such remarks are most misleading. 



Black- headed Gulls {L. ridihundus), as in our own lists, 

 provide the greatest number marked, viz., 381, and of these 

 seven, all marked in Zeeland, have been recovered — one in 

 south Holland, one in Belgium, three in northern France, 

 one in the south of France, and one in north-western Spain. 

 Of these the most striking is the one reported from Palavas- 

 les-Flots in the Gulf of Lion on August 9th, it having been 

 " ringed " as a nestling in Zeeland on June 25th, 1911. 



Reports of recovered birds bearing the Leyden ring should 

 be sent to Dr. van Oort at the Museum, Leyden, with full 

 particulars of the number, and date and place of recovery. 

 We wish every success to our Dutch confreres in this under- 

 taking.
