Species of the Ochlesidae sensu stricto are revised. Based on new material from inshore and continental-shelf Australian marine habitats five new species are described: Meraldia birgeri n. sp., M. madeleinae n. sp., M. yorki n. sp., Ochlesis caroleoninae n. sp., and O. morgani n. sp. As these new species show remarkable sexual dimorphism, both sexes are described and fully illustrated. The world species are diagnosed, and a key to all species is provided.

A new approach to the conceptualization and assessment of human intelligences is de-scribed. According to Gardner's Theory of Multiple Intelligences, each human being is capable of seven relatively independent forms of information processing, with individuals differing from one another

A general problem in biology is how to incorporate information about evolutionary history and adaptation into taxonomy. The problem is exempliÞed in attempts to deÞne our own genus, Homo. Here conventional criteria for allocating fossil species to Homo are reviewed and are found to be either
