180 Zoological Notes, by Andrew Brotherston. 



Nabdean Mill pond, last autumn, by the gamekeeper here. 



Goosander (Mergus merganser). — I have seen several of these 

 birds in the Whiteadder during the past winter. 



Red-throated Diver (Colymbus septentrionalis). — A Red- 

 throated Diver was caught near the village of Hutton, in No- 

 vember last. It was unable to fly, and had been apparently 

 driven inland by the previous stormy weather.

Monstrosity in Domestic Goose. — On May 28th, 1876, I pre- 

 served a young Goose, which had three legs ; it was otherwise 

 perfect. The extra limb was situated behind the others, and 

 like many instances of the same sort, it was a union of two that 

 were imperfectly developed. It was not articulated to the body, 

 but hung loosely, so that it could not have been used in walking 

 if the bird had lived, which it did for a few days only. It was 

 most likely the "produce of a double-yolked egg. 



Black Water Vole. — Although this variety of the Water 

 Vole — or perhaps distinct species — has been overlooked in this 

 district until lately — " Proc." viii., p. 286—1 believe if looked 

 for, it will prove to be not uncommon in this neighbourhood. 

 In addition to the island at Sharpitlaw; I have seen it from other 

 two localities — one four miles down the Tweed, the other about 

 four miles up from here. One, an adult male, was shot May 

 13th, 1876, by Mr Cowe, in the mill-dam at Lochton, Berwick- 

 shire. The other I saw at Trows Crags, Roxburgh, on the 14th 

 of June following. Like the one formerly noticed, they were 

 not so large as the Common Water Vole. 



Tueted Duck (Anas fuligula) breeding (?) on the Borders. — 

 From seeing two — male and female — of these birds on Yetholm 

 Loch, May 27th, 1876,* I think it very probable that they would 

 nest there. I was there again in July, but owing to the high 

 wind blowing at the time, could not see them. I had not the 

 opportunity of seeing them again until the autumn, after the 



* On May 2, 1877, I counted about fifty Tufted Ducks on Yetholm Loch, 

 and on May 26, I saw eight pairs on the same Loch. On Hoselaw Loch, on 

 the same day, there was a larger number. — A. B.
