of England and India. 27 
have stated, in the description both of D. pyriformis and of D. 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 molecule, if the chlorophyll-cells and brown 
cells should hereafter prove to be homologous with the “granules”. 
We shall find the latter particularly marked in Huglypha com- 
pressd, n. sp., and in Cyphoderia margaritacea, Schlum., where 
they are globular in the former and oblong in the latter (PI. I. 
fig. 13k, & Pl. II. fig. 18 7). 
Diffiugia 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 ,rd, breadth nd, aperture ;1,th 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 + 5,th of an inch in 
diameter, and so much like the earlier or acapsular stage of the 
‘reproductive cells” of Ame@ba 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, elliptical, colourless bodies, which I 
took to be the “granules,” might have been thus considered 
(fig. 7d). 
Diffiugia Bombayensis,n. sp. Pl. 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 =1,th of an inch long. 
Loc. Island of Bombay.
