fusion of several zoospores, of about 002 — 005 mm. diame- 
ter, with a few ramifying, very fine pseudopods. 
Resting condition, a roundish Lepocytode, whose mem- 
brane throws out wedge-shaped warts, which jiroject inwards. 
Zoospores spindle-shaped, very contractile, furnished with 
several (two ?) flagella, moving themselves in the manner of an 
Anguillula. 
Locality. — In decaying Nitella from fresh water in Ger- 
many and Russia (Cienkowski). 
Genus V. — Protomyxa, Haeckel. 1 
(Compare above, p. 34.) 
Generic character. — A simple shapeless protoplasm-body 
(with the formation of vacuoles) , which protrude ramifying 
and anastomosing pseudopods. Reproduction by zoospores, 
which combine together into plasmodia. 
Species. — Protomyxa aurantiaca, Haeckel. 
See Plate IX, figs. 1 — 12. 
Protoplasm-body, a plasmodium of orange-red colour, 
which (always ?) originates from the fusion of several 
zoospores, of 0 - 5 — 1 mm. diameter ; with very numerous and 
very thick ramifying and anastomosing pseudopods, which 
form a network by many anastomoses. Resting condition, 
a globular Lepocytode of 015 mm. diameter, with a thick 
structureless covering (cyst) . Zoospores pear-shaped, at the 
pointed end cone-shaped, produced into a very strong flagel- 
lum, at first moving in the manner of the zoospores of the 
Myxomyceta, and afterwards creeping along in the manner 
of an Amoeba. 
Locality. — On empty shells of Spirula Peronii floating 
about on the open sea, and driven in on the coast of the 
Canary Island Lanzarote, 1867. 
Genus VI. — Vampyrella, Cienkowski. 2 
‘ Archiv fur. Mikrosk. Anat./ vol. i, p. 218. 
Generic character. — A simple shapeless protoplasm-body 
(without the formation of vacuoles), which protrudes simple 
or ramifying pseudopods. Reproduction by the formation of 
tetraplasta; the encapsuled resting body divides first into 
1 HpwrofivKa, original slinic. 
2 Diminutive of Vampyrus.
