- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 59 , Six species of the genus Chascanopsetta are currently recognized. Recent work on otolith morphology from specimens identified as C. lugubris raised the possibility that three forms of C. lugubris are found in the western Indian Ocean. Re-examination of the voucher specimens showed that one of these forms is a new species, C. kenyaensis, from Kenya and Somalia. The other two forms may show differences in otolith morphology due to ontogeny. The new species most closely resembles C. prorigera from the Hawaiian Archipelago, Emperor Seamounts, and the western North Atlantic. These two species differ in lateral-line scale counts, body depth, upper-jaw length, and coloration. Many comparative specimens of C. lugubris were examined. It was found that this species’ distribution rounds the Cape of Good Hope from the southwestern Indian Ocean into the southeastern Atlantic. Specimens from this southern African region show higher dorsal- and anal-fin ray counts than those from more northern areas in the Atlantic, western Pacific, and Indian oceans. There is some indication that what some authors refer to as the Indo-West Pacific subspecies C. lugubris lugubris rounds the Cape of Good Hope and also occurs in parts of the eastern Atlantic. A more thorough comparison of C. lugubris from different regions is needed.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 58 , Bothus swio is described based on one adult male specimen collected off the coast of Mozambique. Males of this species appear to differ from all known congeners because of their narrow interobital region. Other characters useful for its identification are lack of ocular appendages, relative positions of the anterior margins of the eyes, number of lateral-line scales, length and colour pattern of the ocular-side pectoral fin, lack of orbital spines, dorsal- and anal-fin ray counts, and lack of colour pattern on the blind side. Bothus swio most closely resembles B. pantherinus and B. tricirrhitus.

- Description: While South Africa's new democracy has meant that schools are now open to all, there is still racism in our schools. The changes in schools have in some cases exacerbated racial tensions and mistrust. Teachers everywhere are struggling with the changing dynamics of their classrooms and schools. There is much talk about how to work against racism. Various programmes and schools have developed different ways of dealing with it. All have particular ideas about how best to counter it. Resisting Racism aims to discuss and understand the beliefs and assumptions underlying many of these approaches. We look at the theories behind the different practices, present a range of ideas to illustrate them and consider their limits and possibilities. The book is a starting point for teachers and schools to reflect on their practices and help them to work out new strategies in the classroom and school. The approaches described will probably work best if they are used together, specially adapted to the specific context in which they are to be used. In the first part of the book we look at psychological and sociological explanations of why people are racist. Four different ways of looking at the issues are described. Each suggests practical ways of dealing with racism in the classroom and in the school. Chapter Three, on multi-cultural and anti-racist education, covers similar ground but from a slightly different angle, looking at curriculum debates about race, culture and equality. The final section looks at the concerns that many teachers have every day, such as "How can I deal with the language problem?" and "How can I involve parents in these issues?" In discussing these questions we have tried to use current theory to inform the practical ideas suggested. You will discover that this book is not neutral. It does have a point of view. It seeks to explain the limitations of assimilating students into a status quo and asks that schools take a critical look at their policies and practices. There are no easy answers or quick solutions. However thinking about and understanding the issues of racism and the ways in which it may be resisted can only bring us closer to positive change.
