2 Mr. D. A. Bannerman : A Revision 



determine whether specimens (apparently quite adult) have 

 passed into the final stage of plumage which they assume. 

 Only more material can decide this point, and it is quite 

 possible that my views will then have to be modified. 



A key to the species is included, which, it is hoped, will 

 be of some assistance to future workers. 



In each case the type-locality is clearly stated, together 

 with a reference to the original description. 



Mr. Ogilvie-Grant has very kindly examined the entire 

 group with me and assisted me greatly in making the key. 



The geographical distribution o£ the genus Haplopelia, 

 which is confined to the Ethiopian Region, has been worked 

 out as carefully as possible. 



The headquarters of the genus may be said to be in 

 the Gulf of Guinea and the adjoining mainland, from which 

 district and islands I recognize six races, not including 

 H. forbusi (type-locality unknown) which most probably 

 came from the west coast of Africa, perhaps Gaboon. 



Travelling across Africa from west to east after Cameroon 

 has been passed, we next meet with a member of the genus in 

 Uganda, where H. simplex jacksoni inhabits the Ruwenzori 

 country. In eastern Africa the genus is represented by two 

 forms only (a third has been described from Nyasaland, 

 but is not distinct). H. larvata larvata has an extensive 

 distribution ranging from British East Africa to the Cape, 

 and there is a small representative race, H. I. bronzina, 

 inhabiting Abyssinia. 



The genus Haplopelia (originally spelt Aplopelia) was 

 created by Bonaparte in the ^ Conspectus Generum Avium,' 

 1854, p. 66, and characterized as follows : — " Remigum 

 secunda tertiam aequante ; cauda mediocris, truncata.^' 

 The type of the genus is Haplopelia larvata (Temm.). 



In dealing with the various races of Haplopelia, I have 

 come to the conclusion that they are best divided into two 

 main sections : (A) those having chestnut under tail- 

 coverts ; (B) those without chestnut under tail-coverts, in 

 which case these feathers are either pale cinnamon, grey, or 

 white.
