APPENDIX. 
DESCRIPTION OF PLATE VIII. 
Fig. 
ie Cystophrys Haeckeliana (gen. et sp. nov.), seen in its ordinary condition, the 
pseudopodia fully and equally extended; the cells showing their light-coloured 
nucleus and nucleolus, and, occasionally, the bluish granular contents showing 
a somewhat large, reddish one; one of the cells showing self-fission. 
2. The same, endeavouring (and finally succeeding) to encompass a fibre of wool, 
some of the internal cells seemingly getting thrown off in the effort, the delicate 
sarcode layer becoming stretched along and round the extremity of the wool. 
One or two of the cells show self-fission. 
8. Cystophrys oculea (sp. nov.). 
The outline of the reddish nuclear bodies is hardly sufficiently strongly indicated 
by a sharp dark line, nor is the inner nucleolar black dot sufficiently pronounced. 
It is difficult to execute these details, even on a scale of 400 diameters. In some 
of the inner cells will be seen double nuclei, presumably indicating progressing 
self-fission. If it were possible to render the very slender pseudopodia by colour- 
less silvery lines, it would be more true to nature; but the figure will, it is hoped, 
enable observers to identify this form. 
4, Heterophrys myriopoda (gen. et sp. nov.). 
In this figure, by some accident, the marginal region or border has been drawn 
at the left-hand side of greater depth than at the remaining three-fourths of the 
circuit; it ought to be pretty equidistant all round. The remark made as to its 
being focussed down to the extreme margin here holds especially good; it will be 
of course understood the outer region intervenes between the central chlorophyll- 
bearing otherwise rather hyaline body and the observer. 
5. Clathrulina elegans (Cienkowski). 
It is hard to convey the transparent character of the perforate skeleton of this 
pretty creature, combined with the light brownish colour proper to fully developed 
specimens. The pseudopodia are rendered somewhat too thick and pronounced ; 
they are very delicate and colourless. 
All the figures x 400.
