Oidemia deglandi. 1891. Maine (Lake Umbagog). May 23. While rowing down the lake we discovered three of those Ducks swimming well out from shore, nearly opposite Black Island Cove. We got within about one hundred yards of them when they rose and flew up the lake. One was a fine Drake, the other two females. We could dis- tinctly see the white spot on the head of the male and the white secondaries of all three gleamed in the sun as they flew past the over-grown-clad shores. " 25. A fine adult male swimming in the lake off Great Island; the wind east and the lake very rough. He was shy rising before we could get within gun-shot.
