Body of large size, presenting during active move- 

 ment a rounded, oval, or elongated figure, often broadly 

 lobed and irregular. Adult individuals opaque, from 

 the presence in the colourless endoplasm of an extra- 

 ordinary quantity of incepted matter, consisting of 

 mud, sand -particles, and decayed vegetable debris; 

 bounded externally by a thin layer of finely-granular 

 or hyaline ectoplasm. With the other contents, there 

 may often be observed various organisms which 

 have been taken as food (enclosed in large vacuoles) 



* Described as abnormally large forms of the species to which they were 

 referred.
