An interesting list of the members of six species of Anas (A. boschasy A. 
crecca, A. penelopey A. clypeatUy A. acutay and A, stre^iera) talmn during thirty- 
five seasons at this celebrated Lincolnshire decoy. The largest number was 
6357 in 1834-6, and next 6059 in 1852-3, the smallest was 936 in 1865-6, and 
next 1132 in 1836-7. A. boschas though usually, as might be expected, by 
far the most numerous species, was in many years surpassed by A. crecca.
