Abstract
THIS volume comprises only forty species, but it contains the important genus Lacerta, and this has been submitted to an intensive study of the individual variations of the species and their many varieties. The author rightly calls the available material unique in its vastness, due, we may add, to his untiring, purposeful exertions during the many years he has been in charge of the cold-blooded vertebrates in the national collection. He deemed it important to ascertain the extent of variation of which a given form is susceptible and in what direction a given variation trends, and then to decide what characters have been modified, or lost, and what new ones produced.
