The island abounds in rare birds, and some of re-

gigantea — the prince of plantain-eaters — as large

richer plumage. The orange-crested bush-shrike, 
Malaconotus clirysogaster ; the yellow-billed coucal, 
Zanclostomus fiavirostris ; plumage glossy violet, and 
purple above, cinereous below, with a tail of rich deep 
blue. The purple-headed grakle, Lamp'otornis ptilo- 
norynchus; the golden-eared grakle, Lamprotornis 
chrysonotis; and a third, supposed to be new ; all of

cUoronatus; the red-collared sunbird, Ginnyris chaly-

rinia chloropygia. A beautiful species, one of which
