Grismer brings together an impressive amount of original field and laboratory research, supplemented with a thorough review of existing literature, to present a first-rate accounting of the Baja California herpetofauna. This book sets the stage for further research of the reptiles and amphibians of this remarkable region."—Robert Hansen, Editor, Herpetological Review "Grismer is without question the foremost authority on the herpetofauna of the Baja Peninsula; no one else could have produced such a detailed, comprehensive treatment of the amphibians and reptiles of the area. The book stands as a monument to Lee's many years of dedicated work on the Baja herpetofauna and will be the standard reference on the subject for many years to come."—Julian C. Lee, author of The Amphibians and Reptiles of the Yucatán Peninsula
