Review of the hardback: 'As a text it is particularly valuable in that it collates information from what is a very widely scatted literature in not always easy-to-access sources. As a reference book, it will act as a god-send to many students, researchers and more generally-interested zoologists.' Biologist Review of the hardback: 'The author … has to be congratulated on the publication of this volume … the data presented will certainly stimulate further research, and many scientists will be thankful for this source of information published in one volume. The chapters include detailed comments and insightful interpretations.' Mammalian Biology
