Book Description
The osteology of over 160 species of fossil and Recent plectognath or tetradontiform fishes is described and illustrated in relation to the supposed phylogeny and proposed higher classification (subfamilial to ordinal levels) of this group of approximately 320 Recent species of primarily tropical and temperate forms of the Atlantic, Pacific, and Indian oceans. The history of the classification and of the previous work on the osteology of the order is reviewed, while one new species (Acanthopleurus collettei, Oligocene of Canton Glarus, Switzerland) and one new genus (Eotetraodon, Eocene of Monte Bolca, Italy) are described. Comparative inclusive and exclusive definition are given for all higher categories based on both external and internal anatomical features. The Order Plectognathi (Tetraodontiformes) is divided into two suborders, the Sclerodermi or Balistoidei and the Gymnodontes or Tetraodontoidei, with a variety of other infraordinal and superfamilial categories, and 10 families, with subfamilial groupings in 4 of the latter.

Book Description
The second installment in a planned three-volume series, this book provides the first substantive review of South American rodents published in over fifty years. Increases in the reach of field research and the variety of field survey methods, the introduction of bioinformatics, and the explosion of molecular-based genetic methodologies have all contributed to the revision of many phylogenetic relationships and to a doubling of the recognized diversity of South American rodents. The largest and most diverse mammalian order on Earth—and an increasingly threatened one—Rodentia is also of great ecological importance, and Rodents is both a timely and exhaustive reference on these ubiquitous creatures. From spiny mice and guinea pigs to the oversized capybara, this book covers all native rodents of South America, the continental islands of Trinidad and Tobago, and the Caribbean Netherlands off the Venezuelan coast. It includes identification keys and descriptions of all genera and species; comments on distribution; maps of localities; discussions of subspecies; and summaries of natural, taxonomic, and nomenclatural history. Rodents also contains a detailed list of cited literature and a separate gazetteer based on confirmed identifications from museum vouchers and the published literature.

Book Description
The vast terrain between Panama and Tierra del Fuego contains some of the worlds richest mammalian fauna, but until now it has lacked a comprehensive systematic reference to the identification, distribution, and taxonomy of its mammals. The first such book of its kind, Mammals of South America both summarizes existing information and encourages further research of the mammals indigenous to the region. It includes identification keys and brief descriptions of each order, family, and genus. Species accounts include taxonomic descriptions, synonymies, keys to identification, distributions with maps and a gazetteer of marginal localities, lists of recognized subspecies, brief summaries of natural history information, and discussions of issues related to taxonomic interpretations.
