“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 Hussey in the 
Great Sound, but I am not sure that any other specimens were pro- 
cured. Lieutenant Denison records one shot in Devonshire Swamp 
on 22d January, 1876.
