Mr J. Hahvie-Bijowx exhibited a specimen of the Ivory Gull shot in Rox- 

 burghshire on 9th March last. JNlr Harvie- Brown read the following 

 remarks, communicated to him by Mr Andiiew Buotiiehston, Kelso : 

 " As there would appear to be two species passing under the name of 

 Ivory Gull — namely, Pagophila ehurnea and P. hrachytxirsus* — and 

 as I have not access to full enough descriptions to enable me to judge 

 as to which of the two this example belongs, I took the opportunity of 

 bringing it with me for the purpose of identification. The relative 

 length of the wings and tarsi appear to be the chief points of difference. 

 The dimensions of this specimen when fresh were : Length from bill to 

 end of tail, 18| in. ; do. to tip of wings, 20^ in. (that is, 2 in. beyond 

 tail) ; expanse of wings, 3 ft. 6 in. ; wing from flexure, 13| in. ; tarsus, 

 Ig in. This specimen, which is a male, was shot at Cessford, in 

 Roxburghshire (nearly thirty miles inland), on 9th March 1883, by Mr 

 W. Barr Scott. When first seen, it was feeding on the carcase of a sheep, 

 on which it had completely gorged itself, being full to the throat when 

 I received it. I may mention that, although ]\Ir Scott is making a 

 collection of birds for himself, he has very kindly presented it to the 

 Kelso Museum, which is a great acquisition to that institution ; as, so 

 far as I am aware, it is the only one that has been obtained on the 

 eastern Borders."
