solving the Cellulose skin. Anything like a mouth cannot, however, be 
seen in the Colpodella, though the entry of the contents proves that there 
must be some kind of opening. 
After this gorging of aliment the Zoospore passes at once into its quiescent 
stage, without the intervening phase of Amoeboid life. The Zoospore balls 
itself into a round mass, containiDg the ingested green matter in one aggre- 
gate lump and showing a clear peripheral border, which ultimately hardens 
into a membrane. Assimilation of food now begins, the clear portion of 
the ball increasing in depth around the body, until after advanced digestion 
the green colored food disappears, colorless plasm fills the whole cell, with 
the exception of a red colored residuum of aliment. Segmentation of the 
colorless mass is next observed, and new Zoospores are gradually formed. 
Their manner of exit from the parent ceil differs however from that of the 
Zoospores already described. In the former instances the Zoospores make 
their separate exit through separate openings in the Capsule. The Col- 
podella parent cell becomes egg-shaped, thins, and finally gives way at one 
end, and the new Zoospores are born in a mass, surrounded with a mem- 
brane, and move about enclosed in this for a time until the membrane wears 
away, and the individuals are then free. 
Lieberkuhn was the first to observe (1855) this peculiar mode of feeding 
in an oval colorless Monad, which by means of one or more projecting 
portions of its body, was seen to suck out the primordial cell of Eudorina 
elegans with such force as to shew the rapid movement of aliment into its 
body. 
Of the second genus of Lepo-Monera only one species (Protomyxa 
aurantiaca) is given by Haeckel, who alone has seen it. I refer you to the 
Microscopic J ournal for full description, directing your attention also to 
the fig. copied from Hseckel, with the characters assigned to the creature 
described by the author. " Protoplasm body, a plasmodium of orange red 
color which originates from the fusion of several Zoospores (0 5 — 1 mm. 
diameter) with very numerous and thick ramifying and anastomosing 
pseudopods, which form a net-work by many anastomoses. In resting 
phase a globular Lepocytode (encysted mass without nucleus) 0*15 mm. 
diameter, with a thick cyst, Zoospores pear-shaped ; the pointed end pro- 
duced into a strong flagellum, at first moving in the manner of the Zoospores 
of the Myxomyceta and afterwards creeping along in the manner of an 
Amoeba." 
The third genus is named Vampyrella of which three species are described 
by Cienkowski, whose account we again follow : —
