This work contains ten very long and thorough chapters by noted authorities in the field. The volume was conceived as the most comprehensive treatment of the phylogenetic relationships among lizard families since the publication of Charles L. Camp's 'Classification of the Lizards' published in 1923, about 93 years ago. This volume is from the research library of herpetologist Kevin W. Marx with his signature on the front endpaper. The abstracts for the chapters appear together at the end of the volume; Marx has added the text page number that links each abstract to its chapter.
