  represented at Woods Hole



Genus AMOEBA Auct.

The pseudopodia are lobose, sometimes absent, the body then
progressing by a flowing movement; the body consists of ectoplasm and
endoplasm, the latter being granular and internal, the former hyaline
and external. There is always one nucleus and one vacuole, but both
may be more numerous. Reproduction takes place by division or by
spore-formation. Fresh-water and marine.


Amoeba guttala Duj.  Fig. 1.

A minute form without pseudopodial processes, extremely hyaline in
appearance, and characterized by rapid flowing in one direction.
The body is club-shape and moves with the swollen end in advance.
A comparatively small number of large granules are found in the
swollen portion, while the smaller posterior end is quite hyaline.
Contractile vacuole absent, and a nucleus was not seen.  Frequent in
decomposing vegetable matter. Length 37µ. Traverses a distance of
160µ in one minute.

The fresh-water form of _A. guttula_ has a vacuole, otherwise
Dujardin's description agrees perfectly with the Woods Hole forms.
