Extract

An interesting zoo-geographical study of the islands and the mainland of the East African coastal region, has just been completed and the results have been published as a paper in the proceedings of the Zoological Society of London (1941). Messrs. Moreau and Pakenham in this study have raised the question of the age of the faults, which played such a large part in causing the separation of the island of Pemba. They quote Sir Edmund Teale and C. Gillman: “ There is no reason why land connections should not have persisted long after the Miocene, and probably right into the Pleistocene.” The purpose of the following article is to restate the facts and to discuss the above conclusion. In the view of the writer no new geological evidence has arisen to cause him to change his original estimate, that Pemba Island dates from the late Miocene or early Pliocene (1928).
