A new volume in the Pacific World series which has proved its right to a permanent place in scientific libraries. An astounding number of the books of this series were sold for use by the armed forces in the Pacific, and interest has extended beyond the purely scientific market to a lay market. This is the first book of its kind, and the authors have selected fishes and shells most widely distributed through the Pacific area, and made this virtually a scientific catalogue -- or dictionary -- of the forms, their habits, origins, etc. People other than students of natural history would find the material repetitive -- it is definitely a reference book rather than one for reading. But the illustrations make it a valuable book for identification purposes. Nichols is a curator at American Museum of Natural History: Dr. Bartsch is with the Smithsonian Institution.
