The Linnæan Barbuts, comprehended by Latham under one genus, contain three distinct groups of birds; which, from their peculiar characters, no less than their geographic position, have now received generic distinctions. The first of these (which are still retained under the old genus,) are natives of Asia; the next in affinity were first characterized by Illiger under the name of Pogonias, and are distributed on the African continent; while the prototype genus in America is Tamatia (Cuvier), in which continent not any of the two preceding have been found: thus each quarter of the globe lying within the tropics have their corresponding groups of a family, possessing a general, but at the same time an individuality of character.
I am obliged to Mr. Leadbeater for the opportunity of figuring this new and rare species, which he believes to have come from Sierra Leone. Its total length was six inches; the under-covers of the wings white; the tail two inches long, the feathers broad and even.
