The taxonomy of the genus Synodontis (Pisces: Siluroidea) in Lake Kainji, Nigeria

This paper considers the taxonomy of most of the synodontis spp. present in the main drainage basins of West Africa. The first section consists of a key to the sixteen species known to occur in Lake Kainji. Nigeria. A second section considers species which are reputed to live in the area and therefore might occur in the lake. It is suggested that several of the latter group are synonymous with better known species.
