256 PROCEEDINGS OF THE 



Harlequin Duck. — Cosmonetta histrionica (Lin.). One specimen 

 of this beautiful and rare bird was obtained at Strathbeg a good 

 many years ago.* 



Golden Eye. — C languid, glaucion (Lin.). A regular winter visit- 

 ant. 



Buffel-headed Duck. — Glangula albeola (Lin.). There is a male 

 of this species in the Banff Museum, which was shot many years 

 ago at Strathbeg. It was presented to the Museum by the late 

 Rev. Jas. Smith, of Monquhitter. Another specimen of this 

 species was shot at the Loch of Loriston in January, 1865. f 



Long-tailed Duck. — Harelda glacialis (Lin.). Large flocks of 

 this duck frequent the estuary of the Deveron in severe winters. £ 



Eider Duck. — Somateria mollissima (Lin.). Is generally seen on 

 the coast near Aberdour in severe winters, and is occasionally met 

 with at Strathbeg. § It is also included in the list of birds of 

 Peterhead. 1 1 



Obs. Smew. — Mergus albellus, Lin. Mr. Thomas Edward 

 has no doubt that, from the description of a bird killed at Strath- 

 beg, it must have been a Smew. It was, unfortunately, destroyed 

 by a dog. 



Goosander. — Mergus merganser, Lin. Pretty common in 

 severe winters, and a few are to be seen every year. 



Bed-breasted Merganser. — Mergus serrator, Lin. A regular 

 visitor, but in small numbers. Several have been shot at Brucklay 

 Castle and at Aberdour. They are frequently seen on the coast 

 and at Strathbeg. 



IV. — Entomological Notes bearing on Evolution. 



By Mr. Peter Cameron. 



In continuation of his paper read at last meeting, Mr. Cameron 

 made some additional observations on the coloration of caterpillars. 

 He remarked that the pale hairs over the legs or over the entire 

 body of those larvae which feed on the flat surface of the leaf, or 

 rest during the day on bark or lichen, was to prevent a sharp 

 shadow being thrown by the body, and so lead to the detection
