much paler than that of the Tufted Duck. General appear- 

 ance pale chocolate-brown^ with conspicuous white centres. 

 Size the same as that of the Scaup and Tufted Duck. 



**■ With more material to work upon it may be possible to 

 detect certain characteristics by which the eggs, down, and 

 feathers of the Ring-necked Duck may be separated from 

 those of the other members of the genus Nyroca mentioned. 

 From the material I have very carefully examined, I am at 

 present unable to distinguish any marked characteristics by 

 which they could be safely indentified.

Mr. BuNYARD also exhibited a clutch of three eggs of the 

 Sanderling (Calidris grenaria) from Viking Vatyn, N.E.

 he knew they were not Dunlin's, because they were taken in

 They were shown by Mr. Plumb to Standeu of Owen College 

 Museum, who thought they were Sanderling's. He also 

 made a comparison with the four eggs in the British Museum, 

 and was at once struck by theisimilarity of his eggs — one of 

 them, in particular, as he says, would have made up a very 

 nice clutch of four. They were also sent to Marsden of 

 Bristol, who was sufficiently satisfied to offer £5 for them. 

 They, however, remainen in Mr. Plumb's collection for some 

 time, but were eventually sold to Mr. Wm. Westhead of 

 Preston, from whose collection they came into my possession, 

 when the collection was sold at Stevens's Booms on 

 Oct. 15th, 1915 — ' Whitehead,' as printed in the catalogue, 

 being a misprint. Mr. Plumb mentions these eggs to me in
