its apertures, and which is borue aloft at the summit of a slendei* 

 stipes, the latter attached by a somewhat expanded base to foreign 

 objects, or one to auother. 



Acanthocystis Cart. Rhizopod composed ol' two distinct 

 sarcode regious, the inner dense, hyaline and with or without co- 

 louring granules, of a globnlar and somewhat rigid figure, the 

 outer colourless, soft and delicate (sometimos difficult to be discer- 

 nedj, bearing a number of more or less elongate siliceous spicula, 

 discoid at the base, and arranged in close approximation vertically 

 lipon the periphery of the inner sarcode body, which gives off, 

 through the outer region, and reaching beyond the radiating spi- 

 cule, a variable number of very slender, delicate, non-coalescing gra- 

 nuliferous pseudopodia. 



Bhaphidiophrys Arch. Rhizopod composed of two di- 

 stinct sarcode regions, the inner forming one or several rounded 

 individualised definitely bounded hyaline sarcode masses, each con- 

 tainig a subperipheral Stratum of colouring granules, the outer more 

 or less coloured, soft and mobile, bearing numerous elongate irre- 

 gulär ly scattered siliceous spicula, acute at both ends, and forming 

 a common Investment to the inner globular masses , which lafcer 

 give off long slender non-coalescing pseudopodia. 



Heterophrys Arch. Rhizopod composed of two distinct 

 sarcode regions, the inner one more dense globular sarcode masses, 

 often bearing colouring granules, the outer forming a coraplete In- 

 vestment thereto, more or less coloured, not enclosing any spicula 

 or differentiated structures, but giving off at the circumference 

 marginal processes, and allowing the passage forth from the inner 

 sarcode mass of numerous linear, elongate, granuliferous non-coales- 

 cing pseudopodia. 



Pompholyxoplirys Arch. (= Hyalolampe Greeff). Rhizopod 

 composed of two distinct sarcode regions, the inner a dense, colou- 

 red, globular sarcode mass, the outer colourless, bearing a number 

 of separate hyaline globular structures, these disposed in a more or 

 less thick layer around the inner globe, which latter gives off more 

 or less elongate slender non-coalescing pseudopodia. 



Astrodisculus Greeff. Body of two distinct well-marked 

 regions, the outer a hyaline, »porous«, sharply bounded Investment, 

 without any external process (which withstands the action of sul- 

 phuric acid), and gives passage to a number of fine linear pseudo- 

 podia eraanating from the contained inner sarcode mass, which con- 

 tains a globular, smoothly bounded »central capsule« (or sometimes 

 several) with variously coloured contents. 



Cystophrys Arch. Rhizopod changeable in figure, sarcode 

 mass of but gue character, and containing immersed therein more
