70 SARCIDIOBNIS MELANOTA 



(1886) it is abundant, and apparently breeds in Hausaland, about Zaria and in Sokoto. Boyd 

 Alexander (1907) states that it visits the vicinity of Lake Chad from time to time. 



Due to the paucity of information we can only conjecture that it occurs in Camerun and the 

 French Congo. Both Marche and Compiegne (Bouvier, 1878) reported it from Diatakunda, and 

 Camerun Dybowski (Taczanowski, 1874) discovered it in Ubangi, northwestern Belgian Congo. 

 Congo It is a common bird in the Sudan occurring northward even to Kordofan (Strick- 



land, 1850) and Khartum (von Heuglin, 1873). According to Butler (1905) it occurs in increasing 

 numbers on the upper White Nile above El Dueim. Ogilvie-Grant (1902) and von Heuglin (1869) 

 White also state that it is common on the White Nile. The latter saw it also on the Blue 



Nile Nile, and A. E. Brehm (1857) found it about Senaar. I saw it in good-sized flocks 



on the big meres near the Dinder River, eastern Sudan, in February, 1913. In the southern Sudan, on 

 the Bahr-el-Ghazal and the Jur it is abundant (Butler, 1905). Farther east it is found frequently in 

 ., . . Abyssinia, from Lake Tana in the north (von Heuglin, 1873), southward in Shoa, 



Angolalla, Gazelle River, Lake Cialalaka and Lake Haddo (Riippell, 1845; W. C. 

 Harris, 1844; Antinori and Salvadori, 1873; Salvadori, 1888). According to von Erlanger (1905) it 

 was abundant on the Haiiash River. It probably does not extend eastward to the lowlands of Ogaden, 

 nor into Somaliland. 



There are few records for eastern British East Africa, though G. A. Fischer (1885) found it at 

 Engatana, and Lamu. Hunter has reported it for the east side of Kilimandjaro (Shelley, 1889), 

 British Kirk (Shelley, 1881) for Malindi, F. G. Jackson (1899) for Ukamba, Ogilvie-Grant 



East Africa f or L a k e Naivasha (6700 ft.), Horsbrugh for Uasin Gishu Plateau, Sharpe (1902) for 

 Uvuma Island, Victoria Nyanza, and G. A. Fischer (1885) for Kageji, Victoria Nyanza, while John- 

 ston (1902) met with it in Uganda, and Emin Pasha (1891) has recorded it for Tarangole in the same 

 Protectorate. Ogilvie-Grant (1910) reports a flock seen near Fort Portal, Ruwenzori region. It has 

 been found also in Lado, at Bussisi (Emin, 1891) and in the Nyam-Nyam district between the Sudan 

 and the Congo (Piaggio, fide Reichenow, 1900). There is no information by which we can fix its 

 status in most of the Congo Free State, but it is found in the southeast, in the Katanga district 

 _ ., (Neave, 1910), about Lake Tanganyika (Dubois, 1886a), and occasionally on the up- 



per Congo (Chapin, in litt.). In Tanganyika Province (German East Africa) it appears 

 to be not uncommon, especially in the north and the west. Speke (Grant, 1872) and von Trotha (fide 

 Reichenow, 1900) have recorded it from Unyamuesi and Mori Bay, and Schillings (1905) also saw 

 it on Victoria Nyanza. It has been found on Lake Djipe (Volkens, 1897) and breeding on the Natron 

 Lakes and Kilimandjaro (Sjostedt, 1910), while it is known also from Kibaja Massai and Manjara 

 (Neumann, 1898), from Irangi (Reichenow, 1893), from Wiedhafen (Fulleborn ./We Reichenow, 1900) 

 and from Kakoma, Igonda, Marungu, Luwule and Lufuri (Bohin, 1882). Salvadori (1914) recorded 

 it from the Mbusi River, Mozambique. 



In northern Rhodesia the Comb Duck is not common, though it is known to breed on Lake Bang- 

 weolo (Neave, 1910; Salvadori, 1914) and has been recorded from the Kafue River (Boyd Alexander, 

 p, , . 1900). It is abundant, however, on the Upper Zambesi (Bradshaw, fide Stark and 



Sclater, 1906; Holub and von Pelzeln, 1882) and in northwestern Bechuana Protectorate 

 on the Botletli River (Bryden, 1893), on Lake Ngami where it is resident and presumably breeds (An- 

 dersson, 1872), at Kanye (Nicolls and Eglington, 1892). It is fairly abundant also in Portuguese West 

 Southwest Africa, south of the Cuanza River, where it was found at Kakondo, on the Kunene, 

 Africa a t Huilla, Gambos and Humbe (Barboza de Bocage, 1877-81). According to Fleck 



(1894) it occurs in former German Southwest Africa near Rehoboth, Fish River, and Andersson 

 (1872) describes it as common in the rainy season in Damaraland and Great Namaqualand, and breed- 

 ing in Ovampoland. 



South of the Orange River the present species occurs only as a rare straggler. It has been taken on 

 the Kleinmont River, Bathurst Division (Layard, 1875-84), and once in Pondoland, Cape Colony
