5. On a New Species or MusopuaGa. 
By Joun Gou tp, F.R.S., V.P.Z.S. 
Mr. Gould exhibited a drawing, made by Lieut. J. H. Stack, and 
some feathers shed from the tail and wings of a species of Musophaga, 
a specimen of which had been living for the last ten years at St. Helena

feathers above mentioned, Mr. Gould was of opinion that the bird is

phage with which we were previously acquainted. Lady Ross in-
