- Abstract
. A description is given of the more interesting features of a collection from the Ufipa and the Kungwe-Mahare highland areas on the east side of Lake Tanganyika. The forest avifauna proved to be of exceptional interest, fourteen new forms being discovered. On topographical grounds the Kungwe-Mahare avifauna would be expected to have rather stronger affinities with the highlands north of the Malagarasi Depression than with the Ufipa highlands on the south of the Karema Gap. But, in fact, northern affinities are so predominant on Kungwe-Mahare as to indicate the Karema Gap as a major zoo-geographical barrier. This agrees with the tendency of recent geological work to show that the Karema Gap represents a rift valley older than the Lake Tanganyika trough and running north-west from Rukwa. The breeding season in Ufipa apparently bears the same relation to the rainy season as in Iringa and in Nyasaland. that is, starting, for many species, just before the rains break. But on Kungwe-Mahare the forest birds seem to breed appreciably later, and not before the rains.
