* End amceba. General character of Amceba ; composed of homogeneous granular protoplasm, in the 

 normal condition without distinction of ectosarc and endosarc; with a distinct nucleus, but ordinarily 

 with neither contractile vesicle nor vacuoles. Intermediate to Protamceba and Amceba.

 Fig. 26. 

 Initial form globular, passing into spheroidal, oval, or variously lobate forms, mostly clavate and 

 moving with the broader end in advance. Protoplasm more or less distinctly striate when in move- 

 ment. Nucleus spherical, granular; with a large nucleolus. Size of globular forms 0.054 mm. to 

 0.075 mm. in diameter; elongated forms 0.075 mm. by 0.06 mm. to 0.15 mm. by 0.09 mm. Parasitic 

 in company with Nyctotherus ovtilis, Lophomonas, Thelastomttm graeile, etc., in the large intestino of 

 Blatta orientfilis.
