Characteres ut in genere Maci’odipteryx dicto, nisi quod remiges sextus, septimus, et octavus gradatim elongati fiunt, usque

Semeiophorus QMacrodiptergxi') vexillarius, Gould, in Proc. of Zool. Soc. Part VI. 1838. 
The general structure of this species is precisely the same as that of the Macrodipteryx Africanus, Swains, 
and it doubtless represents that bird on the opposite side of the African continent ; still, as the form of the 
wing- is very different, I have ventured to propose for it a sej)arate generic station, leaving future research to 
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.
