From the preface:
"Being situated in the tropical region of Southeast Asia, Hong Kong has a great assemblage of amphibians and reptiles. For many years the need was felt for an illustrated comprehensive book on the amphibians and reptiles of Hong Kong. So the authors began observing these animals in the field and in captivity and taking photographs of them far back in 1976. Their findings were published by the Hong Kong Urban Council in the book Hong Kong Amphibians and Reptiles in 1986. The book was the first major publication exclusively on Hong Kong herpetology. It was well received locally and overseas and was soon sold out.
The aim of this second edition remains the same, viz., to inform the general public about the rich diversity of amphibian and reptilian species that can be found throughout the territory of Hong Kong. The authors have gained considerable experience since 1986, and through their field work and the assistance of interested individuals, they have gathered new information on these animals. This second edition embodies the fruit of their research efforts over the past twelve years. It is hoped that the original information, now considerably expanded, will benefit a wider range of readers: biology teachers, their students, other interested naturalists and even professionals."
