PLATE VI. 
1.—Amphizonella vestita (sp. nov.), showing the “corona” of pseudopodia, 
the outer coat, with its vertical, radial, and parallel markings, its 
clothing of very fine hair-like processes, the subjacent elliptic 
colourless bodies, a dense stratum of chlorophyll-granules beneath 
same, and the internal elliptic “nucleus;”’ the latter, in this 
specimen, posed at the side most remote from the pseudopodial 
region. In this example the chlorophyll-granules are very abundant, 
no crude “food” making itself apparent. 
2.—Another specimen of the same, chlorophyll-granules not so abundant 
as in the foregoing, nor the superficial hair-like processes so long, 
showing several vacuoles, three at the periphery—two of which, at 
the point of greatest distension, press up the outer coat—the third, on 
the bare pseudopodial region; showing, also, two conical pseudopodia 
projecting through the outer coat; a minute reddish coloured alga has 
been incepted as food. This specimen did not disclose the “ nucleus;” 
but there could be no doubt that further examination would have 
revealed it, but it was desirable to sketch the example with its 
natural appearance as regards the other details. 
3.—Another specimen of the same, showing the stratum of elliptic bodies, 
but neither chlorophyll-granules, uor pseudopodia, nor vacuoles; the 
“nucleus” is, however, apparent; this example, though fitfully 
changeable in contour, presents no apparent opening or vacant 
region of the coat, the hair-like processes not evident, and is sur- 
rounded by a somewhat deep, changeable, very subtle, hyaline, bluish 
sarcode-envelope, showing faint vertical lines in its substance. A 
protococcoid” is seen immersed in the body-mass, previously en- 
cepted. 
4,—Separate coat of another specimen of the same, found in the gathering, 
evacuated by the sarcode body-mass, but a few chlorophyll-granules 
and elliptic granules (accidentally) left behind. The outer hair-like 
processes are but short; the general surface presents a coarsely 
dotted appearance. 
5.—Another specimen of the same after application of a weak solution of 
iodine and iodide of potassium; the sarcode body-mass has become 
retracted from the outer, slightly hirsute, now globularly expanded 
coat (thus proving its distinct and independent structure), and has 
become coagulated into several balls, these having retained in their 
substance the pale elliptic granules, but left outside the chlorophyll- 
granules as well as the “nucleus,” which latter is seen to the left, 
having assumed a contracted and lobed, internally homogeneous, 
externally smooth, appearance. 
6.—Three of the hair-like processes which had become somewhat expanded 
and then detached from an example of the same, after the at first slow 
action of sulphuric acid, and then showing a slightly capitate basal 
extremity and pointed apex. 
7.—A preparation by treatment with Beale’s carmine fluid of an example of 
““zygosis” in Acanthocystis spinifera (Greeff), showing in each of 
the “conjugated” individuals the central presumed “ vesicula
