They have not received much attention from Bacteri- ologists and but few have been identified. Lymphosporidium truttie produces a dis- ease in aquaria and among domesticated fishes not yet observed in wild ones from natural waters. The bacteria, Fig. loi, are short rodlike micrococci which grow out into filaments, and infest the gills, blood, muscles, skin and surface generally. This micrococcus Is usually present in cases of Autotoxine of aquarium fishes. Healthy fishes succumb to the bacteria in a few days when inoculated beneath the skin and after a longer time by mixing cultures with their food. It is to be hoped that future investigations will familiarize the fish-culturlst with many other of these bacterial causes of fish diseases, and with methods for their destruc- tion. Sporozoa. This section of the Protozoa includes orders which contain many parasitic genera. The orders of the Cytosporidia are the Gregarinida, Coccidiida, Hamosporidiida and Gymnosporidiida. The orders of Myxosporidia are the Phanocystida and Microsporidiida; and in addition to these are the orders Sarcosporidia, Amcebosporidia and Serumsporidia. Gregarinida. Of this order none of the genera have been found as parasites on freshwater fishes or amphibia. Coccidiida. The freshwater parasites of this order belong to the genera Rhabdospora and Coccidium. R. thelohani have been found in the intestines of the perch, the ovarian tissues of the pike-perch, and in the liver of the stickleback; C. metshinkovi in the intestines of the goby; and C. gasterostei in the liver of the stickleback. None have been found on the Cyprin
