plasm bearing the spherules; e, nucleolus, with layer of granules 
and central cavity ; f, chlorophyll-cells; g, starch-granules. All 
these figures are greatly magnified. 
. 3. The same, effete nucleus of the colourless specimens, after the 
spherules have passed into the body of the animal : a, flocculent 
matter, the remains of the nuclear protoplasm in which the sphe- 
rules were suspended; 6, nucleus, with layer of granules and 
central cavity still remaining; c, granuliferous cells (originally 
the spherules of the nucleus, which have now passed into the 
body of the animal) undergoing multiplication by duplicative 
division; d, starch-granules. All greatly magnified. 
Fig. 4. The same: a, granuliferous cells after they have passed from ‘the 
animal into the watch-glass, now become ciliated; 6, small 
Amebe which also appear in the watch-glass. All greatly mag- 
nified. 
Fig. 5. Difflugia compressa, n. sp., magnified: a, broad side of test; 
b, grains of hyaline quartz-sand; ¢, narrow side; d, grains of 
quartz on the same; e, e, pseudopodia; f,f, dark collar-hke mark 
at the base of the neck of the test; g, h, 7, k, dotted lines show- 
ing respectively varieties in the form of the test; /, aperture of 
the circular variety. It should be remembered that the grains of 
quartz, &c., are only partially delineated over the test, to save 
trouble in the engraving. 
Fig. 6. The same, spheruliferous nucleus of; the spherules more or less 
granuliferous: a, nucleolus; 6, brown cells; ¢, yellow oil-glob- 
ules ; d, starch-granules ; e, reproductive cells; f, one under the 
effect of iodine, showing that it is granuliferous, and not homo- 
geneous like the starch-granule under the same circumstances. 
All greatly magnified. 
Fig. 7. Diffugia urceolata, n. sp., magnified : a, grains of quartz; 6, pseudo-

podia; c, reproductive cells; d, oblong colourless cells or bodies 
(the “granules” ?). The two latter much more magnified than 
the test. 
. 8. Diffugia aculeata, Ehr.; magnified under surface: a, grains of 
hyaline quartz; 5, aperture; c, c, spies; d, lateral view of the 
same, showing a different arrangement of the spmes; e, minute 
pieces of straight filaments, sometimes substituted by the animal 
for grains of sand; f, pseudopodia; g, oblong variety, without 
spines—under surface ; h, lateral view of the same; 2, circular 
variety, with spines all round. 
. 9. Difflugia spiralis, Bailey (mihi); magnified lateral view: a, test; 
b, grains of hyaline quartz; c, posterior view ; d, short filaments 
arranged parallel to each other, but in a tortuous form, substi- 
tuted for grains of quartz. 
. 10. Diffugia ? magnified. Test empty; animal not seen. 
-1l. Difiugia ? magnified ; colourless: a, pseudopodia. 
. 12. Difflugia peltigeracea, n. sp. (provisionally so named), magnified ; 
scale ;};th to z,h;th of an inch: a, test; 0, form of scales; 
c, body of animal in a passive state; d, nucleus; e, e, e, portions 
of food; f, fibrous matter forming a kind of diaphragm; g, an- 
other form of the same on the scale of 4th to ;4oth of an inch 
(for comparison in size with the rest of the tests on this scale). 
Fig. 13. Euglypha compressa, n. sp., magnified ; scale th to 339th of 
an inch: a, broad side of test; 5, scales near aperture; c, the 
same, a little further back; d, spines; e, narrow side; f, broad 
side, on the scale of th to ;};th of an inch (for comparison)
