Mr. Dresser informs me the differences, as stated by Schlegel, are 

 as follows : — 



C. bewicki. 



Bill yellow at base, to, or nearly 

 to nostril. 



Wine, 17| to 182 inches. 

 Tail, 5— inches. 

 Tarsus, 36 to 37 lines. 

 Beak, 39-40 lines. 



C. americanus. 



Bill black, with a very small 

 yellow spot on each side, 

 which is scarcely seen in 

 stuffed specimens. 



Wing, 197, to 20 inches. 

 Tail, 7 T 4 y to 7jlr inches. 

 Tarsus, 42 lines. 

 Beak, 44-45 lines.

 There seems a probability that Bewick's Swan is really the rarer 

 species, i.e., if they can be separated [see Third Report].

Usually appear in numbers on the rocky coasts of the west of 

 Scotland in Nov., and earlier frequent the fresh- water lochs. 

 Widgeon seldom come up our Carron river in Stirlingshire, though 

 they have been killed at times. Two were seen on 8th Dec, 1879. 

 Amongst other Ducks, they came to Loch Tay about a month 

 sooner than usual. 



PINTAIL. 



Dafila acuta (Lin.). 



On the 1st October, 1879, a male Pintail was killed by a punts- 

 man at Culross amongst other wild fowl, and another was brought 

 in to Mr. Hastings, Dumfries, for preservation. Another was
