"A male specimen was shot on the 10th April, 1854, in Pembroke 

 Marshes" (Nat. in B., p. 49). There were several of these Ducks about 

 the islands in the winter of 1874-75, and I succeeded in obtaining two, 

 both males, in immature plumage, at Peniston's Pond, on the 29th De- 

 cember, 1874, and 5th February following. A flock of seven frequented 

 Shelly Bay Marsh, and were also seen by Lieutenant Ilussey in the 

 Great Sound, but I am not sure that any other specimens were pro- 

 cured. Lieutenant Denisou records one shot in Devonshire Swamp 

 on 22d January, 187G.
