Family 4 Paramoebidae Poche 



Genus Paramoeba Schaudinn. The amoeba possesses a nucleus and 

 nucleus-like secondary cytoplasmic structure, both of which mul- 

 tiply by division simultaneously; free-living or parasitic. 



P. pigmentifera (Grassi) (Fig. 174, k). About SO^u long; sluggish; 

 cytoplasm distinctly differentiated; secondary body larger than the 

 nucleus; flagellated swarmers are said to occur; parasitic in coelom 

 of Chaetognatha such as Sagitta daparedei, Spadella bipiinctata, S. 

 inflata, and *S. serratodentata.
