siderable number of minute, but variously sized, opaque 
granules. Along their length, or at the points of fusion or 
where branches are given off, there often occur little variously 
shaped expansions or dilatations, in which a few of the moving 
granules seem to find a temporary repose. At first sight the 
whole looks dead and motionless, but a short observation 
shows the current of these granules along the course of the 
pseudopodia very perceptibly. In very many of the speci- 
mens comparatively large aggregations of granules, considera- 
bly larger than the average, presented themselves, and the 
movement of these clusters was more rapid than that of the 
individual more minute granules. Thus, the cluster or 
little aggregation of granules shown near the lowest specimen 
in the figure of the group of three herewith (fig. 7) took 
about a minute to travel from a position as near the upper 
individual as that now shown occupied by it as regards the 
lowest. Not only is there this slow and rather fitful 
“ cyclosis ” of the granular contents of the pseudopodia, 
but a more prolonged examination soon shows that there 
is a constant but gradual change of position, of degree of 
ramification, and of reticulated arrangement of the pseu- 
dopodia themselves. 
Sometimes a club-shaped or dilated expansion of a pseu- 
dopod, not inosculated with any other, exists in certain ex- 
amples, and, within such, a cluster of coarser granules, similar 
to those seen in the intermediate dilatations of the mutually 
incorporated pseudopodia of different individuals, is usually 
presented (fig. 10). 
These larger, shapeless, and irregular granules may possi- 
bly represent food becoming digested, for it is not readily to 
be seen how such kinds of crude food as ordinarily form the 
nutriment or prey of Rhizopoda could find an entrance into 
the test in their entirety. 
It must, I think, follow, from what has been stated, that 
this creature naturally falls under Dujardin’s genus Gromia. 
But there are further characteristics to be mentioned and 
resemblances to be adverted to which may, perhaps, hereafter, 
in the opinion of some, be found to render its position in that 
genus as possibly not quite tenable. 
When I first endeavoured to make out the characteristics 
of this little rhizopod, and, having regard to the appearance 
presented by the densely granular, bluish, internal body-mass, 
I was inclined to look upon this as equivalent to the 
“ nucleus,” occupying, indeed, it would be true, by far the 
greater proportion of the body. It looked as if this was sus- 
pended in a sarcode mass of quite hyaline appearance, filling
