During the period the sponges described herein were which were used only sporadically in the past and were collected (1963-7), the author was a Research Associate regarded as of marginal value until two decades ago, at the Department of Geology, University of Illinois, paleontology and embryology, are now receiving great participating in a research project on carbonate attention. They have already brought drastic revisions to sediments of the Bimini area, directed by Prof. William systematics, with regard to redefinition and classification W. Hay (Department of Geology, University of Illinois. of higher taxa. Other approaches have recently emerged utilizing biochemistry, histology, cytology, autecology, now at the Rosenstiel School of Marine and Atmospheric and zoogeography, and these promise significant ad Science, University of Miami) and supported by the National Science Foundation. The objective of this pro vance in the delimitation and classification oflower taxa. ject was a study of the relationship between the carbo The rapidly changing state of sponge taxonomy is reflect nate sediments of the Bimini area and the benthonic ed in the paucity of definitive (i. e. widely accepted) revisions of genera and families. The lack of stability and fauna and flora, especially with regard to skeletal ele ments contributed to the sediment.

Book Description
Volume 2 of this collection of papers consists of papers concerning the biological survey samples collected by the United States Bureau of Fisheries steamer "Albatross" in the Philippine Islands region between 1907 and 1910. There are 5 separate papers mainly concentrated on invertebrates such as Salps, pelagic tunicates, sponges, and shipworms, by various authors that are listed as "Parts".

Book Description
Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently Systema Porifera revises and stabilizes the systematics of the phylum to accommodate this new knowledge in a contemporary framework. Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera. Systema Porifera is unique making sponge taxonomy widely available at the practical level of classification (genera, families, order). It is a taxonomic revision of sponges and spongiomorphis (such as sphinctozoans and archaeocyathans) based on re-evaluation of type materials and evidence. It is also a practical guide to sponge identification providing descriptions and illustrations of characters and interpretation of their importance to systematics. Systema Porifera addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space. Systema Porifera describes 3 classes, 7 subclasses, 24 orders, 127 families and 682 valid genera of extant sponges (with over 1600 nominal generic names and an additional 500 invalid names treated). Treatment of the fossil fauna is less comprehensive or critical, although 6 classes, 30 orders, 245 families and 998 fossil genera are mentioned. Keys to all recent and many fossil taxa are provided.

Book Description
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.
