 crons in diameter; the cyst with a single nucleus. 



In dogs 



Entamoeba venaticum Darling. In the large intestine. Simi- 

 lar to E. histolytica. As the dog is experimentally infected with 

 the latter, this amoeba which was discovered from spontaneous 

 amoebic dysentery cases of dogs, in one of which w^as noted ab- 

 scesses of liver, is probably E. histolytica. 



An Entamoeba from the mouth and indistinguishable from 

 Entamoeba gingivalis of the human mouth. 



In cats

 E. histolytica and show typical symptoms. Spontaneous dys- 

 entery due to this human amoeba was also noted.
