length of wing, 2 feet 4 inches; length of wing from carpal, 1 foot 

 6 J inches; tail, 10 J inches; beak, over the cnlmen, lj inches; 

 gape, 1 -J inches; leg, 3 inches; foot, 3-J inches; weight, 4 lb. 6|- oz. ; 

 colour of the irides, yellow. Of course, like all our hawks, eagles, 

 and owls, the Great Eagle-Owl is under ban, and is killed as vermin 

 by keepers and game-preservers, so that its occurrence will be less 

 frequent from year to year; and there is little probability that it will 

 ever be recorded as a species found breeding (unless in captivity) in 

 either Great Britain or Ireland. 



The Chairman exhibited a Horn of a Rhinoceros and a large 

 collection of Polished Agates and other minerals, together with a 

 small collection of Fossils from the Paris Basin, on which he made 

 some appropriate remarks. 



Mr. Peter Cameron exhibited slides illustrating the microscopic 

 structure of the tongues of several species of South American Wild 

 Bees and several specimens of other American Hyinenoptera. 



PAPER READ. 



Additional Notes on the Birds of the North-west of Perthshire. 

 By Mr. William Horn, M.A., Oxon., Advocate. 



Since my paper on the birds of this district was printed — see 

 Proceedings, vol. iv., page 54 — I have received a good many addi-

 as well as to give additional instances of the occurrence of several 

 birds not common in the district. I am also indebted to Col. D. 

 Hay's paper on the Birds of the Tay and its tributaries, published 

 in the Scottish Naturalist, 1879-80-81. 



Whitethroat.— Sylvia rufa, (Boddaert).— Very common about 

 Dunkeld, according to Mr. Brooke, of Cardney, whose authority is 

 quoted by Col. D. Hay. 



Great Grey Shrike.— Lanivs excubitor, Linnaeus.— A specimen 

 was obtained by Mr. D. Dewar, on the 15th November, 1880. It 

 was shot on a hedge at Remony, and the contents of the stomach 

 were the remains of a large sparrow, claws and legs being nearly 

 intact. A male bird, in splendid plumage, measured 10J inches 

 from point of bill to tip of tail.— Oban Times, 18th December, 1880. 



Brambling.— Fringilla montifriwjiUa, Linnaeus.— In the last
