varying from a very pale yellowish-brownish, in some places, to a 
very pale blnisli in others, especially at the circumference, and but 
very slightly granular, while the pseudopodia, and the part whence 
they emanate, appear colourless, or pale bluish. 
In all the specimens I have seen (from three localities), just 
beneath the outer boundary of this sarcode-body there occurs a stratum 
of irregularly scattered, generally elliptic, or rounded, but sometimes 
irregularly figured, very minute, greyish or somewhat purple coloured,, 
sharply and darkly bounded, clear, shiny bodies ; these are sometimes 
comparatively evenly distributed, though without any definite order ; 
at other times more or less crowded in clusters, but do not ever seem 
to extend quite through and through the body-mass. (Pigs. 1, 2, 3.) 
In nearly all the examples I have seen, taken from two out of 
the three situations in which I have met with this form, immediately 
beneath the stratum of bodies just mentioned, there occurred a more 
or less dense stratum of large and conspicuous chlorophyll-granules of a 
deep green tint, the green colouring portion in each forming a horse- 
shoe-shaped or crescenticbody at one side, leaving an uncoloured portion 
at the other, as if enclosed in a wall, these mostly imparting to the 
specimens, at first sight, an appearance almost like some chlorophylla- 
ceous alga (Figs. 1, 2) ; commingled, however, with such examples 
occurred others comparatively poor in chlorophyll-granules, and pre- 
senting under a low power a yellowish grey colour, the elliptic bodies 
being predominant, whilst examples from the third locality showed no 
chlorophyll-granules at all, but abundance of the pale elliptic bodies. 
(Fig. 3.) Eelow the stratum of chlorophyll-granules, when present, 
not however central, but rather to one side, yet not touching the 
periphery of the body-mass, there presents itself an elliptic bluish- 
grey-coloured granular-looking '^nucleus." (Fig. 1.) Although the 
sometimes very densely- crowded elliptic bodies, and chlorophyll- gra- 
nules, render it difficult to discern the nucleus, yet, by a little patience 
and manipulation, the intervening granules becoming in the meantime 
altered in distribution, I have nearly always succeeded in gaining a 
view of this body, without the aid of re-agents ; whilst their use, as 
will presently be mentioned, never fails to disclose its presence. It 
does not appear to be covered by a special membrane or wall. 
Having arrived so far in the descriptive building up, as it were, of 
our form, we have what, if it indeed presented no additional charac- 
ters, would be simply an Amoeba — a variably-figured sarcode-body, 
bearing a ''nucleus," — for quite similar little elliptic, or rounded little 
bodies, as well as chlorophyll-granules, also occur in Amoebge, though I 
am not aware of the latter fact being recorded ; nor would elongate 
pseudopodia be requisite to exist, as the lobe-like expansions of many 
Amoebfe are not more than alterations of outline. 
But to continue the examination of the form before us, we find 
that it can do more than alter its outline from orbicular to sub- 
triangular, or a cornered figure, or present one or more lobe-like pro- 
jections: it can send forth short, more or less elongate, blunt and
