 definite a decision as might have been desired. The forms of coni- 

 rosiris and of minor are considered to be conspecific. 



Native Names 



The following names have been

gathered during perusal of the 

 subject to extensive additions.

Distribution 



This is the smallest of the species of the genus Indicator, and is 

 comparable in size to the two species of Prodotiscus. It is one of the 

 least well known of African honey-guides in spite of the fact that it has 

 a very extensive range in the equatorial portions of the continent. In 

 tropical Africa it occurs from Portuguese Guinea, Sierra Leone, Gold 

 Coast, Togoland, Nigeria, Fernando Po, Cameroons, Spanish Guinea, 

 the Belgian Congo, Gaboon, and Angola (Chitau, Ebanga, Tyi- 

 humbwe), eastwards to French Equatorial Africa (Oubangi-Shari), 

 the southeastern Anglo-Egyptian Sudan (Tembura, Wau, Bahr-el- 

 Ghazal, Bongo, Upper Nile), Uganda, Ruanda (probably), Kenya 

 Colony (chiefly in the western part — Kakamega, southern Guaso 

 Nyero, Sotik, and Mau — but also east to Taveta, and northwards to 

 Kacheliba, near the border of Turkanaland), Tanganyika Territory 

 (recorded, so far, only from the northeastern part — Usambara Moun- 

 tains and the vestiges of coastal forest at Moa), Northern Rhodesia 

 (Mwinilunga district, Kabompo River, Fort Jameson), Nyasaland 

 (Cholo and Ndirande Mountains, Mlanje), and Portuguese East 

 Africa (near Zobue, Kirk Mountains, near the Nyasaland border). 

 There are some statements in the literature to the effect that this 

 species occurs northeastwards to Jubaland in southern Somaliland, 

 and even to Ethiopia, but these seem to be based on ^'erlangeri," a 

 form now considered to belong not to this species but to I. minor.
