This book is the most complete account in existence of a strange group of animals—the spadefoot toads. This small group of species, which, because of their secretive and burrowing habits, the author calls "gnomes of the night," have unusually numerous interesting facts in their life history. The purpose of the book is twofold: to give a factual picture of the lives of the spadefoots, drawing upon the technical literature as well as the author's wide experience with certain species; and to illustrate how a naturalist works, the mistakes he sometimes makes, his correction of them with time and further experience, and the necessity for him to accept and examine critically the comments on his work by others. Gnomes of the Night should appeal to all zoologists, especially those whose interests are in the lives of animals in their natural habitat rather than in the laboratory. Illustrated with maps and photographs, it is a scholarly and fascinating account of little-known but prevalent animals.
