Show PROCEEDINGS OF THR SCIENTIFIC MEETINGS OF THE ZOOLOGICAL SOCIETY OF LONDON. • January 14, 1890. Prof. Alfred Newton, F.R.S., Vice-President, in the Chair. The Secretary read the following report on the additions to the Society's Menagerie during the month of December 1889 :- The registered additions to the Society's Menagerie during the month of December 1889 were 45 in number. Of these 28 were acquired by presentation, 2 by purchase, 1 by exchange, 1 was born in the Gardens, and 13 were received on deposit. The total number of departures during the same period, by death and removals, was 79. Mr. Sclater exhibited a specimen of a very singular Duck, apparently of the genus Tadorna, transmitted to him for determination by Dr. Chr. F. Liitken, of Copenhagen, F.M.Z.S. The specimen had been obtained near ^Vladivostok, N.E. Asia, in April 1877, by Lieutenant Fr. Irminger, then in the service of the Great Northern Telegraph Company. After careful examination Mr. Sclater had come to the conclusion that it was a hybrid, probably between the Ruddy Sheldrake (Tadorna casarca) and the Falcated Teal (Querquedula falcata). It was described as follows :- TADORNA CASARCA X QUERQUEDULA FALCATA (?). (Plate I.) Front, face, space behind the eyes, and neck all round white ; top and back of head, long crested nape, and line beneath the eye black ; back brownish grey, with numerous narrow white crossbars ; wing-coverts all pure white ; primaries black ; inner secondaries PROC.
