Guide to the Amphibians and Reptiles of Caribbean Islands
Larger images, larger maps, and considerably more information will be available in an upcoming book (~2015): Guide to the Amphibians and Reptiles of Caribbean Islands, by S. Blair Hedges.
The book will contain several thousand photos and figures covering the ~750 West Indian species. Photos will include (for many species) males, females, and pattern variants. Hundreds of illustrations will assist identification. Species accounts will include details of size, form, natural history, and conservation.
