Book excerpt: Chameleons form a distinctive part of African biodiversity, and Colin has travelled to all parts of the continent to search for them. He has described 10 new species and three new genera, as well as transformed our knowledge of their distribution and evolutionary relationships. For these studies he was awarded the 2004 Stephenson Hamilton Medal by the South African Zoological Society for outstanding contributions to Southern African zoology. Due to the quality of his photography his pictures are always in great demand. Finally, with the culmination of nearly 30 years of study, the Atlas of African Chameleons is born. It is beautiful illustrated with the author's photography, and filled with a comprehensive and accurate text. It has been a labour of love, but with a qualified bushdoctor in the breech, it has arrived fit, fat and fact-filled. It will enrich African herpetology.
