An extraordinarily large quantity of material has been forwarded to the Berlin Natural History Museum, amongst others, by officials, private individuals, and members of the garrisons abroad. Hence valuable results have been obtained for the zoology of these regions. Amongst the satisfactory results of the ever increasing activity in the zoological exploration of the Dark Continent are surprising and repeated discoveries of unknown species of animals, such as the Okapi (_Ocapia johnstoni_) and a black wild hog, till now completely unknown (_Hylochœrus meinertzhageni_, Oldf. Thomas). With the help of these collections, Professor Matschie, dealing with the mammalia, and Professor Reichenow with the birds, have succeeded in establishing the fact that each separate region of the Dark Continent possesses its own characteristic fauna. And most important conclusions with regard to the distribution of animals have thus been derived from these great systematic collections. My friend Baron Carlo Erlanger, the well-known African traveller, and the only one who has ever traversed Somaliland from end to end, though unhappily cut off by an early death, was able to confirm these theories, with reference to the countries he explored, by the ample collections he systematically formed. The whole science of zoology in relation to geography has been turned on to new lines of research, and has given the most important and most valuable results. Everything should be done to support efforts of this kind. [Illustration: _C. G.
