Sixth East African Weed Science Conference, Nairobi, October 1976

The secretary-general of the East African Community, Z. H. K. Birgirwenkya, formally opened this year's Social Science Council conference—the largest to date, not only in terms of the numbers attending and the papers presented, but also in terms of the number of disciplines and countries which contributed. In addition to participants from Uganda, Kenya, and Tanzania, papers were presented by academics from Zambia, Malawi, Nigeria, Sudan, Ethiopia, Sierra Leone, the United Kingdom, and the United States. Observers from the Congo (Kinshasa) were also present. Representatives of the three East African governments also participated in several sessions. John Hutton, director of economic research at Makerere, was chairman of the planning committee which organised the over-all framework of the conference, while Mrs Anna Gourlay, as secretary, did immense amounts of work to ensure that all ran smoothly.

Science Conference

Two recent conferences illustrate on-going debates in African studies and dramatically reflect some of the major issues in African politics. Convening in Addis Ababa, December 9-19,1973, the Third International Congress of Africanists adopted a broad theme: “The Economic, Social, Political, Scientific and Cultural Development of Africa.“ The Ninth Annual Social Science Conference of the East African Universities, which met in Dar es Salaam, December 18-20, 1973, focused on “Rural Development.“

S.rodhaini (Brumpt 1931) is a parasite of East African rodents which may possibly hybridize with the human schistosome S. mansoni. The adult male at maturity measures approximately 3mm long and possesses both oral and ventral suckers and a marked gynaecophoric canal. The oral sucker is surrounded by a ring of sensory receptors with a large number of inwardly-pointing spines set into deep sockets occupying the bulk of the ventral surface of the sucker. Numbers of scattered sensory receptors are found on both dorsal and ventral surfaces of the head (Fig. 1) together with two conspicuous rows of receptors situated symmetrically on each side of the midline. One row extends along the dorsal surface of the head midway between the dorsal midline and the lateral margin.
