A palm-sized guide to the native mammals of Costa Rica, as the author puts it, "larger than a loaf of bread." She includes some of the smaller species too, 65 in total. Each gets a nice description, small paw print and handsome full color illustration. With a map, viewing tips and a checklist. A talented illustrator, Reid also provided the color plates for the wonderful Mammals of Central America (CAM60).  (CRC37, $6.00)
