Body initially a rounded or ovoid particle of yellow- 
ish-green or brownish protoplasm, about 50 mw in dia- 
meter, resembling an Amaba at rest; the endoplasm 
densely crowded with pigmented corpuscles, rendering 
it nearly opaque; surrounded by a light-greyish or 
colourless border of granular-looking ectoplasm, from 
which, at different points, when the animal begins to 
move, pseudopodia are slowly emitted. Usually the 
body becomes ellipsoid, and pseudopodal development 
takes place at each extremity; the body gradually 
elongates and the ribbon-like pseudopodia break forth 
into extremely fine filaments, “apparently extruded 
from the general mass” (Lankester). They may be 
straight and rigid, or gently curved, and are susceptible 
of movement from side to side. The pseudopodia 
occasionally anastomose, and the fine filaments also 
have a tendency to unite; and they may sometimes 
branch or bifurcate. The animal is sensitive to any 
disturbance. When active it will vary in form from 
sub-spherical to ovoid or sub-triangular, the ends, or 
angles, being the points where the larger masses of 
filaments originate. Simultanéously with these move-
