This comprehensive new book replaces and substantially expands upon the landmark Fishes of Arizona, which has been the authoritative source since it was first published in 1973. Inland Fishes of the Greater Southwest is a one-volume guide to native and non-native fishes of the lower Colorado River basin, downstream from the Grand Canyon, and of the northern tributaries of the Sea of Cortez in the United States and Mexico. In all, there are in-depth accounts of more than 165 species representing 30 families. The book is not limited to the fish. It provides insights into their aquatic world with information on topography, drainage relations, climate, geology, vegetational history, aquatic habitats, human-made water systems, and conservation. A section of the book is devoted to fish identification, with keys to native and non-native families as well as family keys to species. The book is illustrated with more than 120 black-and-white illustrations, 47 full-color plates of native fishes, and nearly 40 maps and figures. Many native fish species are unique to the Southwest. They possess interesting and unusual adaptations to the challenges of the region, able to survive silt-laden floods as well as extreme water temperatures and highly fluctuating water flows ranging from very low levels to flash floods. However, in spite of being well-adapted, many of the fish described here are threatened or endangered, often due to the acts of humans who have altered the natural habitat. For that reason, Inland Fishes of the Greater Southwest presents a vast amount of information about the ecological relationships between the fishes it describes and their environments, paying particular attention to the ways in which human interactions have modified aquatic ecosystemsÑand to how humans might work to ensure the survival of rapidly disappearing native species.

Excerpt from A Catalogue of the Fishes Known to Inhabit the Waters of North America, North of the Tropic of Cancer: With Notes on the Species Discovered in 1883 and 1884 The Synopsis of the Fishes of North America, by David S. Jordan and Charles H. Gilbert (bulletin United Sf tes National Museum N o. 16) was finished in September, 1882, and was issued to the public about April 1, 1883. Since the publication of that work an active study of North Ameri can fishes has brought to light many species not included in the Synop sis, and has shown various errors in the nomenclature of species already known. The additions are chiefly in the Bassalian or deep-sea fauna of the Atlantic, in the tropical fauna of the Florida Keys, and in the fresh-water fauna of the lower part of the Mississippi Valley. It was at first determined to issue these addenda in the form of ah nual supplements to the Synopsis, but the publication of the supplement for 1883 having been delayed till January, 1885, it has been thought best to unite the lists for 1883 and 1884, and to put the matter in the present form. I have, therefore, given a list representing the present state of our knowledge of the fishes found north of the Tropic of Cancer, in American waters. In all cases where a species is included which is not in the Synopsis, or in which a name is used in the latter work, different from that here adopted, I have given an explanation, reference or description in the form of a foot-note. Species already fully described elsewhere in publications of the U. S. National Museum are not redescribed here.
