The registered additions to the Society's Menagerie during the 

 month of December 1889 were 4.5 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 deter- 

 mination by Dr. Chr. F. Liitiien, of Copenhagen, F.M.Z.S. The 

 specimen had been obtained near Wladivostok, 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 casarcd) and the Falcated Teal 

 {Querquedula falcata). It was described as follows : — 



Tadorna casarca x Queruuedula falcata (?). (Plate I.)

 top and back of head, long crested nape, and line beneath the

 bars ; wing-coverts all pure white ; primaries black ; inner secondaries
