DESCRIPTION OF PLATE XVI, 
Illustrating Mr. W. Archer’s paper on Rhizopoda. 
Fig. 
1. — Acanlhocystis Pertyana (sp. nov.). A few of the acute radiating 
spines shown thrown off. 
2. — Raphidiophrys viridis (gen. et sp. nov.) 
It will be understood, in reference to this figure (as well as the 
other figures on this and succeeding plate), that the object is drawn 
as seen when focussed down to the equatorial margin, being brought 
distinctly to view, and that, of course, the outer investing stratum, 
here bearing spicules innumerable, is really interposed between the 
globular central bodies and the observer; but being sufficiently 
transparent, this intervening stratum allows the central bodies to 
be seen through it. If it were possible, the pseudopodia should be 
rendered by a delicate, pellucid, almost silvery line, not by a black 
one ; but this cannot be avoided. 
3. — Belerophrys Fockii (gen. et sp. nov.) 
To this figure the same remark applies. The marginal pulsating 
vacuoles are seen at the highest point of distension. The drawing 
attempts to indicate the appearance often presented by the “ tongue- 
shaped ” processes projected from the margin of the outer stratum ; 
but not unfrequently there is no definite outline, when it becomes 
difficult to discern where this region terminates. 
4. — Pompholyxophrys punicea (gen. et sp. nov.) 
The outer vesicles, of course, cover the whole of the external sur- 
face of the reddish body, though seen only at the margin, being, as 
before, focussed down. The body contains a minute captured Cym- 
belia. The figure hardly represents the reddish granules sufficiently 
individualised ; the contents are not so homogeneous-looking. 
5. — The same, submitted to pressure, some of the pigment-granules crushed 
out, and some of the outer vesicles scattered. 
All the figures X 400.
