composed of pale, colorless, granular protoplasm, with 

 abundance of coloring matter, oil-like molecules, and 

 vacuoles. Pseudopods as Actinophrys-like rays, Acineta-

Body brick or orange-red, with hyaline periphery, 

 commonly spherical, but capable of much change of 

 shape. Pseudopods Actinophrys-like rays, and also lobate 

 extensions, together with Acin eta-like rays [rays with
