Soc. Part VI. 1838. Tur general structure of this species is precisely the same as that of the Macrodipteryax Africanus, Swains. § | I yi prery: and it doubtless represents that bird on the opposite side of the African continent ; still, as the form of the wine is very different, I have ventured to propose for it a separate generic station, leaving future research to § Wy ? I § prove whether I have taken a correct view of the subject. Little is known respecting this singular species further than that it inhabits the islands lying between those of Bourbon and Madagascar ; that it is numerous on the shores of the Red Sea and in the Island of Scutra. The figure is of the natural size.
