BIOLOGY^ OF THE PROTOZOA 



In many cases the blepharoplast, which is the central element of 

 the kinetic complex, remains connected with the nucleus by a rhizo- 

 plast as a permanent record of the intranuclear origin of the entire 

 complex (Fig. 47). In many cases the blepharoplast is double, 

 as in most biflagellated forms (Fig. 46, A); in others it is triple, as 

 in Trimastigamwha jihilippinensis or Chilomastix mesnili (Fig. 45, B); 

 in some it is quadruple, or contains foin* basal bodies as in Tricho- 

 monas; in others it is multiple, forming a ring of blepharoplasts about 

 a bundle of Hagella as in Lophomonas hJattarum (Fig. 98, p. 212).

Finally in flagellates with multiple nuclei (family Caloni/niphidoe), 

 in addition to a number of free })lepharoplasts and parabasal bodies, 

 each nucleus is accompanied by a blepharoplast which gi\es rise 

 to three uniform flagella and one longer, band-formed flagellum, by 

 a parabasal body, and by a rhizoplast (axial thread, Fig. 49). 



Many of these aggregations of kinetic elements are sufficiently 

 complex to justify the term neuromotor system of Sharp and Kofoid 

 and appear to form a coordinated whole as shown by the reaction 

 after maceration when they retain their connections and remain 

 together for some time after the supporting protoplasm has disap-
