Abstract
THE latest portion of this useful work begins with a concise and good general account of the hydrography of the North Sea and Baltic, with charts and diagrams, occupying forty-four pages. The remaining eighty-eight pages are taken up by a treatise on the Sporozoa. Omitting the Sarcosporidia as only occurring in the muscles of land vertebrates, Dr. Reichenow divides the group into Telosporidia, Cnidosporidia and Haplosporidia. Most of the known forms belong to the Telosporidia, a fair number to the Cnidosporidia and only a very few to the Haplosporidia. Marine Sporozoa are found in various worms, especially polychætes, in echinoderms, molluscs, crustaceans and tunicates, besides several in fishes. The author wisely places in his lists many species which have not yet been found in the area dealt with, but as they occur in the Mediterranean, parts of the English Channel and the west of Scotland, the distribution may easily extend farther and their inclusion adds much to the value of the work. This also applies to the general account of the structure and biology which covers all these species and not only those so far found in the North Sea and Baltic. Good descriptions and figures are given and the life-histories of many forms are illustrated.
