The second revised edition of An Introduction to Reptiles is carefully organized, clearly written textbook emphasises the origin and evaluation, structure, function and life of reptiles, both existing and extinct, with special emphasis on their adaptation to different modes of life. The subjects that receive special attention are: adaptive radiation, Dinosaurs, skull of reptiles, sphenodon cheonia. One of the principal aims of the book is to present the account in simple language and in straight forward manner, avoiding grotesque phrases, in order to make the reading easy and assimilation quick.

Aves constitute a well-defined group of vertebrates. They possess a sense of strongly marked characters such as distinguish hardly any other class.

An Introduction to Birds is the second revised edition of the book. The text is designed to approach the morphology, anatomy, physiology and development of the Birds in a coherent way.

The book features both a text and a laboratory guide. It deals with the structures and psychological phenomena and each system. Origin, adaptive radiation and other general topics are also details in details. It is hoped that this book will not only meet the requirements of Indian students but will also be useful as a guideline to the teachers in their teaching.

An introduction to Amphibia is designed to approach the anatomical features of amphibians, dealing with the structural and physiological phenomenon of each system. This book is a comprehensive guide though it does not burden the students with unnecessary details. Easy understandable illustration, correct and latest information are the main features of this title.

The present second revised edition of the book consists of seventeen chapters, namely Amphibia: characters and classification; Rana tigrina; Integument Endoskeleton; Musculature; Digestive system; Respiratory system; Circulatory system; Nervous system; Sense organs; Urinogential system; Development of frog; Parental care in amphibians Neoteny & Paedegenesis; Stegocephalia; Origin and evolution of amphibian Courtship and mating in amphibians etc.

This text is designed to approach the morphology, anatomy, physiology and development of the Fishes in a coherent way since it is most natural for a students in studying the architectural elements of an animal body in the quest to know how they function. This text intends, therefore, to enable the student, through his own natural appetency, to correlate form and function so that he possesses for subsequent work in either anatomy of physiology a firm foundation for a real edifice of knowledge.

The book features both a text and a laboratory guide. It deals with the structure and physiological phenomena of each system. Origin, adaptive radiation and other general topics are also dealt in details. It is hoped that this book will not only meet the requirement of Indian students but will also be useful as a guideline to the teachers in their teaching.
