590 Mr. J. H. Guruey's Notes on 



Grey Falcons obtained in Iceland (continued). 



Wing. Tarsus. Middle toe s. ti. 



Presumed females (four) 



Presumed males (seveu) 

 Presumed females (five) 



It is unfortunate that the majority of the Grey Falcons 

 preserved in collections have no authentic information at- 

 tached to them as to the country from which they were 

 obtained ; but I believe that the localities of those of which 

 I have given the measurements above may be relied upon as 

 authentic. It is also in some cases impossible to say from what 

 localities the originajs of several of the plates which have been 

 published of grey Arctic Falcons were obtained ; but there are 

 two cases in which I am able to supply this information. Mr. 

 Dresser, who does not admit any subspecific distinction be- 

 tween H. islandus and H. holbadli, has given as the figure of 

 the adult '* Iceland Falcon " the portrait of a specimen killed 

 in Greenland, which he has been so good as to lend to me 

 for examination f ; and Mr. Wolf, as I have already men- 

 tioned, has figured, in his ' Zoological Sketches ' J, a specimen 

 of H. islandus which was obtained in Iceland by the late Sir 

 William Milner in 1851, and, having died ten years later in 

 the Gardens of the Zoological Society, is now preserved in 

 the Norwich INIuseum. 



Mr. Dresser^s specimen above referred to has the curious 



* This specimen is remarkable for having the feathers of the lower 

 back and upper tail-coverts cross-ban-ed and tipped with pm-e white, in- 

 stead of with pale bluish grey as is usually the case both in H. islandus 

 and H. holbosUi.
