ENTAMOEBA OF REPTILES AND FISH

(1910c) in the rectum of the newt. Triton palmatus, and by Alexeiefi 

 (1912) in Triton tcBniatus, is very possibly E. ranarum. 



Hartmann (19106) described as E. testudinis an amoeba of the tor- 

 toise, Testudo grcBca. It was also seen by Alexeieff (1912c) in Nicoria 

 trijuga, a tortoise of Ceylon, while the writer has met with it in Testudo 

 argentina and T. calcarata. An Entamoeba of the turtle, Chelydra serpentina, 

 of America, which was cultivated by Barret and Smith (1923), has been 

 named Entamoeba barreti by Hegner and Taliaferro (1924) (see p. 207).

Dobell (1914a) gave a figure of an entamoeba seen by him in the 

 wall lizard, Lacerta tnuralis. The writer (1921) encountered a similar 

 amoeba in Egyptian lizards {Lacerta agilis and Agama stellio). The free 

 forms were very like those of E. coli, while eight-nuclear cysts occurred 

 which were indistinguishable from those of the human parasite. What 

 is probably the same amoeba was seen in Lacerta ocellata by Franchini 

 (1921a). Cunha and Fonseca (1917) described as E. serpentis an amoeba 

 seen by them in the snake Drimobius bifossatus of S. America. 



Leger and Duboscq (1904) observed an amoeba in the intestine of the 

 marine fish Box boops and B. saljm. It was studied by Alexeieff (1912), 

 who placed it in a new genus as Proctamoeba salpcp. According to him,
