Uganda has a long tail (Table 1), suggesting that A. binotata has to be considered with present knowledge as a monotypic taxon, with several geographically well-separated populations (but see below). is a somewhat larger species, differently proportioned and apparently mensurally more sexually dimorphic (especially in tail length-Table 1). It is generally distributed in the montane habitats of eastern Zaire, from the Lendu Plateau in the north to the Marungu in the south (the Marungu population is slightly different in colour and some- what larger; it is considered as a separate race — marungensis Chapin 1932). A. personata's range includes parts of Rwanda and in Uganda the Impenetrable forest and the Ruwenzori mountain (Britton 1980). Jackson (1938) considered it to be numerous on the Ruwenzori and it is also a common bird on the Zaire side of this mountain (Chapin 1953). Apparently it occurs normally above 1500 m , but Prigogine (1971) gives one locality at 1270 m in Itombwe. Prigogine also collected it in the Beni-Butembo area at about 1400 m.

In A. binotata the entire crown and forehead are dark grey in the adult male, the rest of the upper parts being Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrat
