pedition of 1900 a great many were seen by the officers and men and 

 some shot by the latter though I failed to obtain any skins. It 

 approaches very close to British limits in Sadya, being found on 

 the high ranges above, and only some 12 miles distant from, the 

 border Police posts.

When my articles on " Indian Ducks and their Allies " were com- 

 menced in this Journal, it will be remembered that on the strength of 

 Humes' and Salvadori' s identification of the head and feet of a swan 

 in the British Museum this species was admitted by me as one of our 

 Indian avifauna. Further investigation by Blanford however showed 

 that these parts had undoubtedly belonged to a specimen of the 

 Whooper Swan (Cygnus musicus) and Bewick's Swan had accordingly 

 to be expunged from our list. 



It is therefore extremely satisfactory to be able to record that an 

 undoubted specimen of Cygnus bewicki, Bewick's Swan, has been shot 

 by Mr. R. L. McCulloch of the Indian Police at Jacobabad in Sind. 



The skin* has been very kindly forwarded to me for identification, 

 and I have no hesitation in describing it as a very fine adult specimen 

 of the above swan. The whole plumage is perfectly pure white, there 

 being no trace of grey or rusty on either upper or lower plumage, and 

 we may therefore assume that the bird has reached its full dimensions 

 and we can place full reliance on the measurements of bill and feet, the 

 main determining factor in identification. 



The comparative measurements of this specimen of Bewick's Swan 

 is given with average measurements of the Whooper, Cygnus musicus, 

 to show the difference — 



Wing. Tarsus. Bill from gape. Culmen. 



The Whooper ... 25" to 26" 4-2" to 4-5" 4" to 4-2" 4-2" 



Bewick's Swan ... 20-25" 3-75" 3-75" 3-8" 



The exact measurements of the tarsus of this skin of Bewick's Swan 

 are as follows : — 



Tarsus at front from centre of ankle joint to toe 3*95", at side 3'75" 

 and from behind to hallux S'O".
