Wing, tail and bill lengths of Hooded Vultures were measured on 36 wild-caught birds and 75 in museum collections. A further 60 measurements were taken from literature, and 40 measurements were received from the Musée royal de l’Afrique centrale (Tervuren, Belgium). By grouping them into regions of Africa it was shown that the smallest birds were in West Africa and the largest in southern Africa (which is well known), with a gradation in between. Sizes varied according to a cline, and were correlated with average altitude. Given that the species has the same colouration (head, caruncles, plumage) from one end of the range to the other, indeed that populations are contiguous from Senegal to South Africa, then this goes against recognising any subspecies, but rather an intraspecific trend in sizes

As with many of the other national parks in the Republic of South Africa, an effort has been made to determine the species of small mammals in the Kalahari Gemsbok National Park (KGNP) (Rautenbach 1971; Rautenbach and Nel 1975). An additional feature of such species inventories has been the use of owl pellets to determine the occurrence of small mammals in a given area. This has been done in the KGNP as well as other parts of southern Africa (Davis 1958; Nel and Nolte 1965; Nel 1969; Vernon 1972; Coetzee 1972). Such inventories of species of small mammals are critical as the KGNP has become an important study site for desert rodent ecology (Nel 1967; Nel and Rautenbach 1974; Nel 1975; Nel and Rautenbach 1975).

Opening ParagraphIn a recent paper Mr. C. K. Cooke, F.S.A., discusses the questions of the introduction of sheep into Africa and their arrival in southern Africa (Cooke, 1965).Mr Cooke quotes Zeuner's conclusion (Zeuner, 1963) ‘that the first sheep in Africa were screw-horned hair sheep from Turkestan or Persia which reached lower Egypt about 5000 B.C. and Khartoum by 3300 B.C. This breed disappeared with the Middle Kingdom when it was replaced by a wool sheep and the fat-tailed sheep reached Africa only from the Roman period.’ Zeuner further asserts thatOne breed of sheep descended from the Egyptian hair-sheep had reached South-West Africa before the arrival of the Europeans. In these animals the profile is convex, the eyes are placed high on the skull and close to the drooping ears. The rams carry thick horns and a long ruff on the throat.

World attention has been drawn in recent years to the intensification of organized militant action by Africans against the white ruling powers of southern Africa. The incidents have been sporadic, inadequately organized and equipped, doomed to fail from the outset. Nevertheless the governments have responded with comprehensive legislative and executive action to maintain “law and order” — undoubtedly a legitimate responsibility of any government, but one presumably to be reached by means that accord with norms of justice and the rule of law. Thirty-six men from South West Africa are currently being tried in South Africa for some allegedly terrorist activities on the basis of a law reflective more of a government that intends to maintain power by any means than one that is cognizant of standards of justice with which it, as much as any individual, should comply.

A revision of the genus Asparagus in South Africa, South West Africa, Bechuanaland, Basutoland, and Swaziland has been undertaken. Notes are given on the value of most o f the characters which have been used in the separation of species, recent literature on the nature of  Asparagus assimilatory organs, and a technique for the examination of chromosomes. Chromosome counts are listed for ten taxa. There is a key to the forty species and four varieties. In the main part of the work these taxa are described, and their synonymy, taxonomy, distribution and habitats dealt with. Six species and one variety are new. The following are the new species and combinations:  A. setaceus (Kunth) (Asparagopsis setacea Kunth), A. mueronatus, A. macowanii Bak. var. zuluensis (N. E. Br.)  (A. zuluensis N. E. Br.), A. rigidus, A. densiflorus (Kunth)  {Asparagopsis densiflora Kunth),  A. aethiopicus L. var. angusticladus, A. falcatus L. var. ternifolius (Bak.)  (A. aethiopicus L. var.  ternifolius Bak.),  A. aspergillus,  A. obermeyerae,  A. krebsianus (Kunth) (Asparagopsis krebsiana Kunth),  A. acocksii.  A. crassicladus. Several plants o f horticultural importance occur in South Africa. The three best known are A. plumosus, which is reduced here to synonymy under  A. setaceus (Kunth) Jessop, and  A. sprengeri and  A. myersii. A. sprengeri is being reduced to synonymy under  A. densiflorus (Kunth) Jessop,.  A. myersii, which is a  nomen nudum, is also regarded as belonging to  A. densiflorus.

Abstract Why did leaders of the Congress movement in South Africa abandon their exclusive reliance on non-violent means in the struggle against apartheid, form an armed unit (Umkhonto we Sizwe), and launch a campaign of spectacular sabotage bombings of symbols of apartheid in 1961? None of the earlier violent struggles from which Congress leaders drew inspiration, and none of the contemporaneous insurgencies against white minority rule elsewhere in southern Africa, involved a similar distinct, preliminary and extended phase of non-lethal symbolic sabotage. Following the 1960 Sharpeville massacre, Congress leaders feared the social and political consequences of increased popular enthusiasm for using violence. Nelson Mandela, Joe Slovo, and the other founders of Umkhonto we Sizwe did not launch their sabotage campaign because they believed it would prompt a change of heart among white South Africans, nor because they believed urban sabotage bombings were a necessary prelude to the launch of rural guerrilla warfare. Rather, the sabotage campaign was a spectacular placeholder, a stopgap intended to advertise the Congress movement's abandonment of exclusive non-violence and thus to discourage opponents of apartheid, both inside and outside South Africa, from supporting rival groups or initiating ‘uncontrolled violent action themselves.

A number of bird specimens, including at least 53 type specimens, were collected by C. J. Andersson (or credited to him as the collector) mainly in Namibia, but also in Angola, Botswana and South Africa, between 1850 and July 1867. Although much of the original material collected by Andersson has been lost, 2,523 bird study skins and sets of eggs collected by him are currently in museum collections; of them 58 are without any data except species name, 202 have the country only, 367 have country and a vague locality (Damaraland, Cape Colony and Ovamboland), and 1,896 have detailed locality data. Although 757 specimens are without dates, another 1,666 have at least month and year, and a further 100 have year only, or can be dated to a particular year. A list of collecting sites and dates when they were visited is given. Of particular interest are the type specimens collected by Andersson and his colleagues as some of these include species with incorrect or vague type localities.

What Southern Africa will look like a generation from now is an immediate problem for the South African Government's top policy makers, who realise the precarious nature of apartheid. These planners have rejected both the do-nothing approach of the right-wing elements (e.g. the Republican Party) in South Africa and the multi-racial society solution pressed by Mrs Helen Suzman, the only Member of Parliament of the (relatively) left-wing Progressive Party. Between these two alternatives a host of partition schemes have been advocated, and one of them has been accepted: the ‘Bantustan’ proposals. By geographical isolation of each of the non-White ethnic groups into separate homelands or ‘Bantustans’, leaving the remainder of the territories of South Africa and South-West Africa to the Whites, the Nationalist Government is proceeding to change the face of Southern Africa.

Three species of Tuberales have been found in Southern Africa.  Terfezia pfeilii Henn. occurs in the Kalahari Desert and adjacent areas of the Cape Province, Botswana and South-West Africa. The other two,  Terfezia austroafricana sp. nov. and  Choiromyces echinulatus sp. nov., are known only from the Cape.  C. echinulatus is the first representative of that genus to be collected in Africa or the Southern Hemisphere.
