Prof. Flower, C.B., LL.D., F.R.S., President, in the Chair. Mr. W. B. Tegetmeier, F.Z.S., exhibited and made remarks on a specimen of a female Gold Pheasant (Thaumalea picta) which had assumed nearly complete male plumage. Mr. Tegetmeier also exhibited a pair of distorted horns of the Ibex of Cashmere (Capra sibirica), in which the horns met in front and crossed each other. The Secretary laid upon the table a list of the species of Fishes contained in several collections made at Constantinople by Dr. E. D. Dickson, C.M.Z.S., and forwarded to the Society. The list had been prepared by Mr. G. A. Boulenger, F.Z.S., and contained the names of 66 species ; amongst these were two specimens of a species of Trout from Broussa, which, although resembling Salmo fario, were, according to Dr. Gunther, probably referable to a distinct species. Further specimens, however, were required for their accurate determination. The Council had agreed to deposit these collections in the British Museum of Natural History in the name of the Society.
