This book provide the entire information required for the taxonomist. The author tried something much more ambitious and tried to examine the deepest foundations of taxonomy and to build up from those foundations the structures of zoological classification. Further characterization of the subject matter is made at the beginning of chapter I, where it is more likely to be read, and the book before you demonstrate for itself what has been made to the subject. All types of Systematics, Taxonomy, Classification, Nomenclature, The development of Modern Taxonomy, Taxonomic Evidence and Evolutionary Interpretation, From Taxonomy to Classification and the classification of species in Lower and Higher categories have been included. The complete classic text is written in simple language and lucid treatment of the subject shall make this book easily readable and highly useful. This book shall serve as text cum reference book for students, teachers and researchers and for all those interested in Taxonomy.
