Burkenroad created two subgenera of the genus Trachypenaeus viz., Trachypenaeus (Trachypenaeus) and Trachypenaeus (Trachysalambria) in 1934.  These two subgenera were raised to the status of genus by Pérez Farfante and Kensley and simultaneously created two new genera for the group namely Megokris and Rimapenaeus.  As such the trachypenaeid group of penaeid prawns consists of four valid genera namely Trachypenaeus, Trachysalambria, Megokris and Rimapenaeus.  During the present study genus Megokris is being synonymised under its original genus Trachypenaeus.  Therefore, the main objective of the present study is to propose a revision to the trachypenaeid group of penaeid prawn and to prepare a comprehensive document for the group recorded from Indian water.  The study area represents genus Trachysalambria and Megokris with three species under each genus.

We provide a synthesis of all mammal taxa described from the African mainland, Madagascar and all surrounding islands in the 20 years since 1988, thereby supplementing the earlier works of G.M. Allen (1939) and W.F.H. Ansell (1989), and bringing the list of African mammals described over the last 250 years current to December 2008. We list 175 new extant taxa, including five new genera, one new subgenus, 138 new species and 31 new subspecies, including remarks, where relevant, on the current systematic position of each taxon. Names of seven species of primates are emended, according to the requirements of the ICZN. The taxonomic group in which the largest number of new taxa has been described is the Primates, with two new genera, 47 new species and 11 new subspecies, while geographically the biggest increase in new species descriptions has been on the island of Madagascar, accounting for roughly half (67) of all new species described in the past 20 years. Nearly half of all new species listed currently are assessed as Data Deficient on the IUCN Red List of Threatened Species (49 of 101 listed species) suggesting further research is urgently needed to help clarify the status of those recently described species.

The case is put for improvisation as the basis for world music, with special reference to flexibility of the blues and the gamelan. An overview of the impact of society on music leads to a general survey of the status of improvisation in pre-industrial Western European culture. Improvisation is contrasted with composition and consideration is given to the problems of providing education in improvisation without destroying its vitality and communicative power.

Wetlands are home to numerous species of fish, birds, and reptiles. The enormous roots of the mangrove trees act as shelter to small fish, reptiles, and amphibians. Pesticides and agro-chemical fertilizers have been playing a very pivotal role in the degradation of the land and the water bodies. The different herbicides that are present in wetlands are Dicamba, Endothall, MCPA, Triallate, Trifluralin, 2, 4-D, and insecticides Carbaryl, Carbofuran, Fenvalerate, Malathion, Parathion, and Terbufos. These pesticides have been provided with the aim of catering to the security of the crops which are highly vulnerable to the pests. However, harmful effects of pesticides on wetland species have been a concern for long time. Wetlands constitute one such habitat threatened by the pesticides. But there has been a lack of comprehensive research in this direction. The chapter will identify the gaps in the current research and will review the status of Indian wetlands with special reference to pesticides and their impact.

Although, as the name of the country suggests, Botswana is populated mainly by Tswana-speaking peoples, it is acknowledged that the most indigenous or aboriginal inhabitants of the country are the San or Basarwa, identified and described in some of the literature as Bushmen. Basarwa also have the less admirable distinction of being perceived and depicted as the most marginalized of all the ethnic groups in the country. Concern about the status, and the political and economic position of Basarwa in Botswana has been expressed in numerous reports and writings, official and unofficial, and at various conferences, seminars and gatherings, national or international.

Australasian pericomoids, psychodids resembling northern hemisphere species of Pericoma Walker (tribe Pericomini), are mostly members of the tribe Maruinini, here re-defined. Amongst Maruinini, they are like several neotropical genera named by Enderlein (1937), but their actual relationship to Enderlein's genera, and hence their identity, has been a long-standing taxonomic problem. Consideration of extensive new collections and observations made in the southern hemisphere now shows that they consist of the following: Genus Notiocharis Eaton. Tribe Maruinini: genus Didicrum Enderlein, and five new genera, Eremolobulosa, Rotundopteryx, Alloeodidicrurn, Satchellomyia and Ancyroaspis. Of these, the Australian Eremolobulosa is the possible sister group of the European Lobulosa Szabo, and the New Zealand genera Satchellomyia and Ancyroaspis are possible sister groups. Of Enderlein's neotropical genera, five classified by Quate (1963) as synonyms, or in one case a subgenus, of Pericoma (Didicrum, Desmioza, Synmormia, Syntomolaba and Podolepria) are recognised as full genera. A key to Australasian pericomoid genera is provided.
