| Deep-water species from the western Indian Ocean off the East African coast and Madagascar, belonging to the subfamily Photinae, are discussed and compared with species from the West Pacific. Phos elegantissimus Hayashi & Habe, 1965, P. hirasei Sowerby, 1913 and P laevis Kuroda & Habe in Habe, 1961 are recorded from Mozambique and/or from Madagascar, hereby extending their known range considerably into the western Indian Ocean. The East African specimens formerly assigned to Phos roseatus Hinds, 1844 are found to differ from this West Pacific species. In total, five species arc described as new: Phos ganii sp. nov., P geminus sp. nov., P. ladoboides sp. nov., P. pulchritudus sp. nov. and P. testaceus sp. nov. |

| This study uses a rich dataset of 85 market pairs between January 2000 and October 2008 for Kenya, Tanzanian and Uganda, the three largest member countries of the East Africa Community, to analyze the factors determining national and cross-national maize price transmission. Although the three countries are members of the community’s customs union and they each claim to pursue maize trade without borders, their agricultural trade policies still differ, thus affecting prices and trade flows to different extents. This analysis extends the existing border effects literature in three ways. First, it assesses the magnitude of price transmission, instead of analyzing trade flows or price variability. Second, distance is shown to have a significant impact on price... |

| Cereal grains are important staple foods in Africa but yields are still too low at 1.5 tons per ha for maize while compared with a global average of 4.5 tons per ha. This can be partly attributed to limited development of commercial seed markets, low use of improved seeds, small and highly fragmented seed markets. Many released varieties are not widely disseminated due to closed national markets dominated by a few international companies and parastatals, and restrictive laws, regulations and policies. Transactions costs within and across national boundaries are high because of differing arrangements across countries. Establishment of common regulatory structures is expected to reduce transactions costs and promote increased trade and hence use of improved... |
