Racek seems to have authored much of this work after the death of J. T. Penney and undertook a study and review of Penny's huge colleciton of material and unpublished data at the recommendation of B. Theodore Cole of the University of South Carolina. In view of the voluminous material available, Racek found it imperative to revise all true gemmule-producing species rather than elaborate Penny's outlined account of the Meyeninae and as a result of the study, demonstrated the fallacy of a subdivision of the family Spongillidae by using gemmosclere characteristics.

Excerpt from Comprehensive Revision of a Worldwide Collection of Freshwater Sponges (Porifera, Spongillidae) In spite of the fact that serious scientific efforts in the taxonomic study of freshwater sponges were begun in the mid-19th century, and that a great number of subsequent investigators have contributed a massive amount of additional descriptive information, the taxonomy of this group has remained in a most chaotic state. Following Bowerbank's (1863) initial revision of all species of Spongilla, Gray (1867) was first to establish useful criteria for their generic differen tiation and to erect six new genera in addition to Spongilla Lamarck. Unfortunately, this system was criticized and its validity questioned by Carter (1881a), who claimed that Gray established his new genera without having seen Bowerbank's material upon which they were erected. Although fully unjustified in doing so, Carter (1881a) alto gether ignored Gray's existing generic names and devised his own system for the inclusion of Bowerbank's species and subsequently collected material. Thus it happened that Gray's well-established genera fell into complete obscurity for many decades, and Carter's system became firmly established, without being seriously challenged by any subsequent taxonomist. From the turn of this century, several attempts were made to revise comprehensively the status of the ever increasing numbers of species. After the publication of the first bibliography of all freshwater sponges by Weltner it was chiefly Annandale (1906 - 1919) who began to build the foundations to an improved and modernized knowledge of spongillid taxonomy. Annandale reestablished some of Gray's generic names, at least at a subgeneric level, and added a number of well-defined new genera to the conglomerate systems of Gray and Carter. Additional revisions were subsequently undertaken by Gee (1926 Schroder (1926 and Arndt (1923 to name just the most important contributors. Generic revisions were attempted by De Laubenfels (1936) and Jewell However, in spite of the fact that all these investigations have certainly helped to overcome a number of taxonomic difficulties, they seemed to have little effect on the stability of taxonomic nomenclature.

Thorp and Covich's Freshwater Invertebrates: Keys to Nearctic Fauna, Fourth Edition presents a comprehensive revision and expansion of this trusted professional reference manual and educational textbook-from a single North American tome into a developing multivolume series covering inland water invertebrates of the world. Readers familiar with the first three editions will welcome this new volume. The series, now entitled Thorp and Covich’s Freshwater Invertebrates, (edited by J.H. Thorp), began with Volume I: Ecology and General Biology, (edited by J.H. Thorp and D.C. Rogers). It now continues in Volume II with taxonomic coverage of inland water invertebrates of the Nearctic zoogeographic region. As in previous editions, all volumes of the fourth edition are designed for multiple uses and levels of expertise by professionals in universities, government agencies, and private companies, as well as by undergraduate and graduate students. Features zoogeographic coverage for all of North America, south to the general area of the Tropic of Cancer, and Greenland and Bermuda Provides keys to families of freshwater insects Provides keys to all other inland water invertebrates at the taxonomic level appropriate for the current scientific knowledge Includes multiple taxonomic keys in each chapter that progress from higher to lower taxonomic levels, thereby allowing users to work up to their level of need and expertise Presents additional material in each chapter on group introduction, limitations to the keys, terminology and morphology, material preparation and preservation, and references

"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.

Thorp and Covich's Freshwater Invertebrates: Keys to Palaearctic Fauna, Fourth Edition, is part of a multivolume series covering inland water invertebrates of the world that began with Vol. I: Ecology and General Biology (2015), then Vol. II (2016) Keys to Nearctic Fauna, and finally in Vol. III (2018) Keys to Neotropical Hexapoda (insects and springtails). It now continues with identification keys for Palearctic invertebrates in Vol. IV. Two other volumes currently in development focus on general invertebrates of the Neotropical/Antarctic, and Australasian Bioregions. Other volumes in the early planning stages include Afrotropical and Oriental/Oceanic Bioregions. All volumes are designed for multiple uses and levels of expertise by professionals in universities, government agencies and private companies, as well as by graduate and undergraduate students. Provides identification keys for inland water (fresh to saline) invertebrates of the Palearctic Zoogeographic Region, from Iceland to Russia, and from the northern Pole region to Saharan Africa in the west, through the Middle East, and to the central China and Japan in the east Presents identification keys for aquatic invertebrates to the genus or species level for many groups and to family for Hexapoda, with the keys progressing from higher to lower taxonomic levels Includes a general introduction and sections on limitations, terminology and morphology, material preparation and preservation and references

Fossil and Recent Sponges contains articles on taxonomic, phylogenetic and ecological aspects of sponges of both biological and paleontological interest. They focus on three main topics: phylogeny and systematics, biology, and paleoecology of sponges. The reader is offered an overview over the most important aspects of current sponge research: - establishment of a new taxonomy based on mono phyletic groups (phylogenetic systematics) including recent and fossil taxa - new concepts of the biomineralisation of sponge skeletons - palaeoenvironmental analysis of fossil sponge buildups.
