PLATE IX ( continued ). 
8. — Two amoeba-like germs (of those represented iu fig. G) seize a diatome 
( Navicula ), eacli at a different end. X 220. 
9. — The same two amoeba-germs as in fig. 8, seen somewhat later, in 
drawing themselves over the Navicula , have encountered in the 
middle, and have here united themselves into one. X 220. 
10. — An older Protomyxa developed into a plasmodium, either from the 
simple increase of a single amoeba-like germ, or by the union of a 
larger number of amoebae. A devoured Isthmia and a Navicula are 
visible in the homogeneous parenchyma of the sarcode, also numerous 
vacuoli ( v ). X 220. 
11. — A full-grown Protomyxa in the best-fed condition, after a very liberal 
diet. In the interior of the central protoplasm-body are numerous 
vacuoli ( v ) ; above are seen two Isthmice still entire, with three of 
the latticed siliceous shells of pelagic Tintinnoidce (two Dictyocysla 
elegans and one D. mitra ) ; one shell seems to be just ejected. 
From the central sarcode-body the very strong, branching, tree-like 
pseudopods radiate; their peripheral anastomoses show numerous 
crescent-shaped meshes. Above, several strong pseudopods have 
seized and surrounded a three-horned Peridinium. The formation of 
vacuoli extends also to the larger pseudopods. X 220. 
12. — A full-grown Protomyxa , fasting, without food. From the entirely 
homogeneous sarcode-body radiate a very large quantity of tree-like 
branching pseudopods, which form only a few anastomoses, and 
are but scantily supplied with corpuscles. The number of vacuoli in 
the central protoplasm-body is insignificant. X 110.
