have stated, in the description both of D. pyriformis and of Z). com- 

 pressa, that neither the chlorophyll-cells nor the brown cells 

 enter the pseudopodia of either of these species respectively ; at 

 the same time that I might have erred in calling their contents 

 granules instead of moleculse, if the chlorophyll-cells and brown 

 cells should hereafter prove to be homologous with the "granules". 

 We shall find the latter particularly marked in Euglypha com- 

 pressa, n. sp., and in Cyphoderia margaritacea, Schlum., where 

 they are globular in the former and oblong in the latter (PI. I. 

 fig. 13 k, & PI. II. fig. 18 /). 



Difflugia urceolata, n. sp. PI. I. fig. 7. 



Test ovo-globose, truncated anteriorly ; aperture wide, even ; 

 margin everted, reflected ; neck obsolete : composed of grains of 

 hyaline quartz-sand. Animal colourless, hidden, with the ex- 

 ception of the pseudopodia, by the opacity of the test. 



Hab. Heath-bog water. Progressing with the aperture down- 

 wards and the test erect. Locomotion performed by obtuse 

 digital prolongations of the body slowly projected from the 

 aperture. 



Size. Length -sV^d, breadth ^nd, aperture xfoth of an inch 

 in diameter. 



Loc. England ; south coast of Devon, Budleigh-Salterton. 



Obs. I have only seen one specimen of this species, and in 

 this the animal was fortunately present and active. On crush- 

 ing the test, no nucleus or starch-granules appeared, but a 

 dozen cells (c), each of which was about iVo-oth of an inch in 

 diameter, and so much like the earlier or acapsular stage of the 

 " reproductive cells " of Amoeba princeps that little doubt could 

 be entertained of their being of the same nature. There 

 was nothing present, either to represent the chlorophyll-cells or 

 brown cells of D. pyriformis and D. compressa respectively, un- 

 less a number of elongated, eUiptical, colourless bodies, which I 

 took to be the " granules," might have been thus considered 



(fig.r.^). 



Difflugia Bombayensis, n. sp. PI. II. fig. 16. 



Test ovo-globose, of a dark-brown colour, truncated anteriorly, 

 aperture even; composed of grains of sand externally, which 

 rest upon a cancellated structure formed of circles of large parti- 

 cles, in the areas of which are scattered a number of smaller 

 ones. No part of the animal seen within the test, on account of 

 its opacity. Pseudopodia numerous, digitiform, obtuse or forked 

 at the extremity. 



Hab. Fresh water. 



Size. About xo-oth of an inch long. 



Loc. Island of Bombay.
