THE HONEY-GUIDES 257 



been taken at Gambos and Caconda; and in Northern Rhodesia at 

 Shiva Ngandu near Lake Young, Namusonde, Namwala, at Chilanga 

 near Lusaka, at Lofu River, Chalimbana, at Tembwe, Lundazi, at 

 Chiromwe, along the middle Zambezi, Danger Hill near Mpika, and 

 the Pempele Pool on the Mwinilunga-Congo border. The bird 

 undoubtedly occurs in many parts of Southern Rhodesia, but I know 

 of only three actual specimen records from that country — from 

 Glsnara, 12 miles north of Salisbury; from the Lundi River, between 

 Fort Victoria and Beit Bridge, where one was taken bj'^ Plowes; and 

 another taken by Plowes in the Matopos Mountains (there are sight 

 records from Gatooma and from Rumani Estate). From Bechuana- 

 land Protectorate it is known from Tsotsoroga Pan. Farther south, 

 in the Union of South Africa, there are many records from the Trans- 

 vaal, Zululand, Natal, and the eastern Cape Province. I am aware of 

 no authentic records of its occurrence in the western portions of the 

 Capo Province, or in the South-West African Protectorate. A speci- 

 men in the Leiden Museum is labeled as from the latter country, but 

 it is from Gambos (Kellen collection), which locality appears to be 

 north of the Cunene River, and is therefore in southern Angola. 



The altitudinal range of the sharp-billed honey-guide is from near 

 sea level up to at least 6,600 feet at Ndu, British Cameroons, 6,000 feet 

 at Lorogi Plateau, Kenya Colony, and 6,500 feet in the Drakensberg 

 Mountains, Natal. 



Throughout this extensive range the species has not become differ- 

 entiated into any recognizable races. Two subspecies, camerunensis 

 from the Cameroons and peasei from Ethiopia, have been named, but 

 neither prove to be valid forms. The recentl};- proposed adustoides 

 from Natal requires confirmation before it can be accepted. 



Seasonal Movements 



As in the other honey-guides, the present species is not migratory 

 in a geographical sense, but there may be some local movements. 

 Thus, near Howick, central Natal, in October and early November 

 1924, I found the species much commoner than the literature or the 

 experience of other observers had led me to expect. In the com-se of 

 two weeks I collected five specimens and every one was found, on 

 dissection, to be a male. It was not until some weeks later, after I 

 had left that area, that my friend Rodin Symons obtained a female 

 there. This experience suggested that there might have been a small- 

 scale migration and that the males arrived before the females, but it is 

 not to be looked upon as more than a suggestion. Some years later 

 (Friedmann, 1930b, p. 100) in summarizing the then existing data, it 

 was stated that "when a species known to be rare throughout its
