by its anatomic characters. Katayawia they consider synonymous with 

 Oncomelania; under it they list Oncomelania (Hypsobia) nosophora 

 and Oncomelania (Hypsobia) formosana. They also refer under 

 Oncomelania {Hypsobia) nosophora Faust's specimens from Shaoh- 

 sing and Fatshan, which I have named Katayama fausti and Katayama 

 cantoni, respectively. 



In 1928 Bequaert (37) published his essay on " Mollusks of Im- 

 portance in Human and Veterinary Medicine." In this he reviews 

 the entire field and places the Katayamas in Oncomelania. He lists 

 Blanfordia nosophora and Blanfordia formosana as hosts of our 

 fluke. 



In 1929 Faust (39) published his textbook, " Human Helminth- 

 ology ", in which he discusses schistosomiasis on pages 94-155. 



In 1932 Tubangui (40) announced " The Molluscan Intermediate 

 Host in the Philippines of the Oriental Blood Fluke, Schistosoma 

 japonicum Katsurada ", in which he refers to Blanfordia japonica 

 and Blanfordia formosana. 



The same year, 1932, Rensch (41) in describing the Philippine 

 intermediate host of Schistosoma, refers to Hypsobia nosophora. 



In 1932 P\i-ching Li published two papers in Science, The Science 

 Society of China, vol. 16. The first of these (42), pp. 566-582, deals 

 with der " Zwischenwirt des Schistosomum haematobium japanicum 

 (Katsurada)"; the second (43) in the same journal, pp. 583- 

 619, deals with " Uber die postembryonale Entwicklung von dem 

 Zwischenwirt des Schistosomum haematobium japonicum China." 

 This contains 32 figures. It is unfortunate that both of these papers 

 are in Chinese, but in a subsequent paper (46), 1934, the author 

 uses German, so we may consider that the data here presented is 

 summed up in that communication. 



In 1934 Bequaert (44) reviews Tubangui and Rensch's papers and 

 incidentally goes over all the ground again, referring to Blanfordia 

 formosana and Katayama nosophora. 



To the same paper Pilsbry (45) adds an appendix, " Note on the 

 Genus Blanfordia " , in which he substantiates Bequaert's conclusion 

 and refers, among other things, to Katayama nosophora yoshidai and 

 Blanfordia nosophora.
