278 BIRDS OF BERMUDA. 



Eev. H. B. Tristram's collection. One was killed by Captain Tolcher, 

 rifty-sixth Eegiment, near Spanish Point, on the 1st February, 1855; 

 it was in company with three or four others. Mr. Bartram has two 

 specimens of different dates.

Three are recorded in "The Naturalist in Bermuda" — two obtained 

 in October, 1849, and one by Major Wedderburn, in February, 1850. 

 Mr. Hurdis once found a perfect skeleton of this bird by the side of a 

 pond. Tolerably abundant in the winter of 1874-'75, especially at Trott's 

 and Basden's Ponds. The way in which these birds can sink under 

 water, without leaving a ripple behind, is truly marrellous, and entitles 

 them fully to the name " Water Witch." They are very shy, but I once 

 surprised one asleep on a flat stone, as much to my astonishment as to 

 the bird's. All the specimens I saw were in immature plumage, want- 

 ing the black bar on the bill and the black throat-patch.
