Prin.Of Systematic Zoology

The authors ernst mayr and peter. D. Aslock are the well known authors zoologists of earlier time. Taxonomy is a subject which is so operational that it cannot learned merely by reading a book. Therefore, the main objective of the volume is to serve as a guide and companion for those who are learning the subject and perhaps even more for tnnose who are teaching it. However it cannot take the place of a laboratory in which the procedures of classification are actually demonstrated. The problems of taxonomy are different in every group of animals, and teachers will want to use material and illustrations from the zoological groups with which they are most familiar. This is why this volume does not cite more examples to illustrate basic principles and methods. The teacher will know best what examples are most instructive in a given case. In the preparation of manuscript ernst mayr wrote a first draft of part a and c, and peter ashlock wrote a first draft olf part b. Erach draft was thoroughly revised by the coauthor and was shown to other readers, whose suggestions were incorporated as far as possible. Chapter 12, 13 and 14 are revisions of chapters 6, 11, 12 and 13 of the first edition. It is with great sadness that i report the unexpected death of professor ashlock of a heart attack on january 26, 1989, while the manuscript was nearing completion. The book has been thoroughly revised and updated in the second edition. At the end in the chapter 14 the rules of zoological nomenclature has been narrated thoroughly and explained in details.
