2 MR. A. THOMSON’S REPORT ON THE 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 
Felis tigris prevalent in northern latitudes. This animal is stated 
to have been captured on the Hari-rud, between Sarakhs and Pul-i- 
Katim. 
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 Gazel/a 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 egyptiaca). 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.
