DESCRIPTION OF PLATES VI & VII, 
Ilustrating Mr. Archer’s Paper on Chlamydomyxa labyrinthu- 
loides, n. g. et sp. 
PLATE VI. 
Plate VI represents an entire example, the body-mass having become ex- 
truded through the torn-like opening in the many-layered outer envelope, 
and showing the greenish, reddish, and bluish-colouring granules, pulsating 
vacuoles, and some incepted foreign bodies. Far extending in a tortuous 
reticulated “labyrinth” are seen the filamentary tracks (Fadenbahn, 
Cienkowski) with numbers of the bluish granules travelling thereon, now 
becoming fusiform in figure (Spindles). ‘Towards the left of the example, 
in an outlying portion of the mass is seen a vacuole showing a temporary 
cleft or rift in the substance at each side of it. Towards the right is seen 
a nearly isolated colony of the mass containing a digested example of 
Oocystis Naegelii. At the further extremity occur two similar nearly 
isolated portions, one showing embedded an as yet undigested example of 
Spiroltenia gracillima (un. s.), all these outlying portions showing some 
vacuoles. ‘l'owards the left of the figure a small portion of the body-mass 
has become on some former occasion independently re-encysted, and is now 
“dormant.” x 400 Diam. 
PLATE VII. 
Fig. 1 shows certain bodies found in the cells of the Sphagnum plant 
occurring in the same pool, and often on the same plants which harbour un- 
doubted examples of this organism (as shown in next figure), and supposed 
to have some genetic relationship. 
Fig. 2.—A portion of a leaf of Sphagnum showing young Chlamydomyxa 
examples ; to the left are seen green ones, near the bottom two very small 
still globular, towards the middle a few now red, owing to the abundance of 
the red granules ; the larger examples have put ona torulose figure, owing to 
the constriction caused by the recurring cincture of the annular fibre of the 
Sphagnum-cell. Towards the right is seen a Chlamydomyxra extruded, and 
still attached by a neck-like portion of the wall; the contents have become 
re-encysted now outside the Sphagnum-cell. 
Fig. 3—A condition rarely met with showing the inner sarcodic sub- 
stance subdivided in a number of nearly equal-sized globular portions, the 
contents reddish inclining to orange, and eack individual ball encysted in its 
proper wall; the whole within the outer many-layered original envelope. 
Fig. 4.—The many-layered envelope of an example after severe pressure, 
ce most of the substance removed, a few colouring granules only being 
eft. 
Fig. 5.—A small example after being boiled in caustic potash. 
Fig. 6.—Portion of an example treated with iodine and sulphuric acid. 
All the figs. x 200 diams.
