44 RAPHIDIOPHRYS. 



GENUS II. HETEROPHRYS. 



Animal resembling Actinophrys, but the body ordi- 

 narily enveloped with a thick stratum of protoplasm, de- 

 fined by a granulated or thickly villous surface, and pene- 

 trated by pseudopodal rays. 



HeterophryS myriapoda. SYN. : H. myriapoda. Archer, 

 Greeff : (?) H. varians, Schulze ; (?) H. variabilis, Greeff . 



Body composed of a soft, usually spherical, granular 

 mass of protoplasm, colorless at the surface, commonly 

 bright-green within, due to chlorophyll corpuscules ; in 

 some conditions with little or no color except such as is 

 imparted by the food ; containing clear, colorless cor- 

 puscles, vacuoles, nuclei, and one or more contractile 

 vesicles. With or without an exterior envelope of proto- 

 plasm. Pseudopods simple, granular rays. Diameter, 

 g-^j- to -3-^5- of an inch (Archer). [The range of this 

 species does not seem to be well established, and it may 

 include forms that are very variable in shape and appear- 

 ance.] 



GENUS III. RAPHIDIOPHRYS. 



Animals ordinarily associated in groups of variable 

 number, closely aggregated or conjoined by isthmus-like 

 bars. Individuals of Actinophryan form, consisting of a 

 soft, spheroidal body of granular protoplasm, with oil-like 

 molecules and variable proportions of clear, colorless or 

 bright-green corpuscles, and a large, central nucleus. 

 Exterior of the body invested with a thick layer of deli- 

 cate, colorless protoplasm, extending in tapering processes
