Humblot's Sunbird is confined to the island of Great 

 Comoro. 



Monsieur Humblot during his expedition to Great Comoro 

 Island discovered this and several other species of birds hitherto 

 unknown to science. 



The Mascarene Archipelago, and the island of Socotra to the 

 north, muster ten local forms of Sunbirds, none of which ever 

 range on to the African continent, and are all referred by me 

 to the two genera Cinnyris and Gyanomitra, and consist of the 

 following species : — 



Cinnyris notatus, Madagascar ; replaced by G. nesophilus in 

 Great Comoro. 



G. comorensis, Johanna Island. 



C. coquereli, Mayotte Island. 



C. souimanga, Madagascar and Gloriosa Island ; represented 

 by C. aldabranus on Aldabra Island and by C. abbotti on the 

 Island of Assumption. 



The genus Gyanomitra is represented by : — 



G. humbloti, in Great Comoro. 



C. dussumieri, in the Seychelles Archipelago. 



C. balfouri, in Socotra Island.
