These genera have certain relations to the organal distribution in the 

 body of the host, which are shown in List IV (page 37) and Table I (on page 

 43) and which can be put together as follows : 



TABLE III 



From the facts shown in the above tables, the following conclusions can 

 be drawn. 



1) The genera Leptotheca (one species in tissue), Ceratomyxa, Myxo- 

 proteus, Sinuolinea and Sphaeromyxa (one species in Amphibia) include 

 parasites from the body cavity of marine fish. 



2) The majority of the genera Lentospora, Myxosoma, Myxobolus (one 

 species in Amphibia), Henneguya and Hoferellus include parasites in tissues 

 of fresh-water fish. 



3) The genera Chloromyxum, Sphaerospora, Myxidium and Zschok- 

 kella include forms that infect the body-cavity as well as the tissue of 

 marine and fresh-water fishes. 



4) The genus Mitraspora includes three species that parasitize the 

 fresh-water fish. 



5) The genus Myxidium has three species found in the kidney of 

 reptiles.
