PLASMODROMATA AND SARCODINA 



I . Intestinal : — 



1. L. coli Loesch, 1875. 



2. L. histolytica Schaudinn, 1903. 



3. L. tetragena Viereck, 1907. 



4. L. tropicalis Lesage, 1908. 



5. L. minuta Elmassian, 1909. 



6. L. nipponica Koidzumi, 1909. 



7. L. undulans Castellani, 1905. 



8. L. williamsi Prowazek, 1911. 



9. L. hartmanni Prowazek, 191 2. 



10. L. hutschli Prowazek, 1912. 



11. L. brasiliensis Baurepaire-Aragao, 1912. 



12. L. dysenteritB europaecB Popper, 191 7. 



13. L. nana Wenyon and O'Connor, 1917. (This is con- 



sidered under Vahlkamfia (see p. 323.) 



14. L. minutissima Brug, 1917. 



The researches of Hartmann, Whitmore, Wenyon, Craig, Calkins, 

 and James, have demonstrated that only two of these are good 

 species, viz. : — 



Loeschia coli Loesch, 1875. 

 Loeschia histolytica Schaudinn, 1903. 

 n. Hepatic and renal 



L. mortinatalium Smith and Weidman, 1910. 



This species was found originally in the liver and kidneys of 

 a foetus born dead. 



III. Buccal : — 



1. L. gingivalis Gros, 1849. 



2. L. buccalis Sternberg, 1862. 



3. L. dentalis Grassi, 1879. 



4. L. dentalis Braun, 1883. 



5. L. buccalis Prowazek, 1904. 



6. L. maxillaris KsLvtuXis, igoi. 



There is only one good species, viz. : — 



Loeschia gingivalis Gros, 1849. 



IV. Genito-urinary : — 



L. urogenitalis Baelz, 1883, which may be the same as 

 Amoeba urincB granulata Ward, Coles and Friel, which 

 the latter suggests comes from an organism like a 

 protococcus taken into the alimentary canal. 

 Chalmers and O'Farrell consider it to be L. histolytica 

 in all probability. 



V. Pulmonary : — 



L. pulmonalis Artault, 1898. 



This may be the same organism as L. mortinatalium Smith and 

 Weidman, 1910, and both may be L. histolytica, as Chalmers and 

 Atkey have reasons for believing that L. pulmonalis is very like 

 L. histolytica.
