ALLIGATORS AND CROCIDILES

Gavials, caimans, prehistoric phytosaurs, the Florida descendants of the beast the Spanish explorers termed el ligator, infest a gem of a book for anyone with a craving for crocodiles. Graphically illustrated by James Gordon Irving's detailed soft pencil drawings, there's some fascinating material here, attractively presented, on these reptiles and their habits. A must for the home museum or the junior science project and Zim has a pre-established young public.
