2 MR. A. Thomson's report on thk insect-house. [Jan. 19, 



M.D., Naturalist to the Afghan Boundary Commission. This 

 specimen seems to belong to the small and densely furred form of 

 Fdls tigris prevalent in northern latitudes. This animal is stated 

 to have been captured on the Hari-rud, between Sarakhs and Pul-i- 

 Katum. 



3. Four young Gazelles obtained during the survey of the 

 boundary of Northern Afghanistan, and deposited by the same 

 gentleman. These Gazelles are probably referable to Gazella sub- 

 gutturosa, but seem to differ somewhat from our previously received 

 specimens of the same species. 



4. Two curious hybrid Ducks bred in 1884, at Cannes, between 

 the Ruddy Sheldrake (Tadorna rutila) and the Egyptian Goose 

 {Chenalopex agypiiaca). This pair of hybrids was presented to Dr. 

 T. E. Charles, of Cannes, by Madame de la Blanchetain, of the same 

 place. Dr. Charles presented them to Sir Joseph Fayrer, who has 

 kindly transferred them to the Society's Collection.
