and Sennar, and to Uganda, east to Eritrea, Bogosland, and the 

 drainage basin of the Blue Nile in Ethiopia. Said to occur in north- 

 ern Kavirondo on the Uganda-Kenya border as well. Slightly larger 

 than the nominate form (wings, 127 mm) and without even a trace 

 of chestnut on the breast, agreeing in this respect with the Angolan 

 form inonteiri. 



3. M. p. sohoannis: Ethiopia and northern Kenya Colony, from the 

 Hawash region and the Shoan lake region, to the Omo Valley and 

 the Upper Webi Schebelli region, south through the Rendile country 

 to the Northern Guaso Nyiro River in Kenya Colony and to Turkana- 

 land in northeastern Uganda. This race has a very distinct, deep 

 chestnut pectoral band sharply marked off from the yellow throat 

 and abdomen; wings, 117-122 mm. 



4. M. p. app7'oxinians : From southern Somaliland and coastal 

 Kenya Colony inland along the Tana River to the southern Ukamba 

 and Kikuyu districts, south to northeastern Tanganyika Territory 

 (Pangani River and Dar es Salaam). Very much like schoa/nus but 

 smaller; wings, 95-112 mm. 



5. M. p. interpositus : The country northwest of Lake Tanganyika, 

 Belgian Congo. Said to be intermediate between approximans and 

 catharoxanthus and very similar to poliocephalus, from which it 

 differs only in having the chestnut band on the breast more distinct 

 and less extensive, that is, more narrowly confined to the pectoral area. 

 Hartert ^* writes that this form must be confirmed by further research. 

 Van Someren -^ records four birds from Mount Moroto and Meuressi, 

 Turkwell, Uganda, as belonging to this form, and says : "One cannot 

 distinguish my four birds from typical M. interpositus^ yet as they 

 occur in the same locality as BI. p. schoanus, it seems to me that they 

 must rank as a species or be united. I prefer for the time being to 

 keep them separate." I can not help but doubt the correctness of van 

 Someren's identification and suspect, from the localities, that his birds 

 are intermediates between catharoxanthus and schoanus^ their geo- 

 graphical neighbors. 



6. M. p. hlanchoti: Tanganyika Territory from Dar es Salaam 

 inland to Mwanza, south through Mozambique, Nyasaland, eastern 

 Rhodesia (Gazaland, etc.) to the Transvaal, Zululand, Natal, and 

 Pondoland. This form differs from approximans in having the chest- 

 nut color on the breast much paler, but still distinct, that is, not faint 

 as in poliocephalus ; wings, 110 mm. 



7. M. p. monteirl: Angola,, probably east to the Katanga. This 

 form differs from all the others in that it has a white patch behind the 

 ear coverts and has the eye completely surrounded by white. It lacks
