72 General Notes. 
The majority of the species enumerated occur in a sphagnum 
swamp on the College farm. The list represents the observations 
of a single season, and will, of course, be extended by closer 
research, i 
References to figures and plates refer to Dr. Leidy’s Rhizopods 
of North America. 
ORDER PROTOPLASTA. 
Widely distributed in sphagnum swamps, the ooze of springs, 
ponds and sheltered coves along the Penobscot. Not plentiful in 
farm. Two individuals were seen which assumed forms like Figs. 
Ameba villosa, Wollich. Page 62, Pls. 1 te Rae 
Several specimens of the general form of Figs. 8 and 9, Pl. 5, 
were seen in the water of a spring on the College farm, associated 
with other Rhizopods. 
Difflugia globulosa, Du Jardin. Page 96, Pls. 15, 16. 
Forms like Figs. 8 and 9, Pl. 16, are not uncommon in sphag- 
num swamps about Orono. 
Diflugia pyriformis, Leidy. Page 98, Pls. 10-13, ete. 
Quite common in sphagnum swamps in the Penobscot Valley. 
Variable in form. 
Not scarce in sphagnum swamps. This form is probably only a 
variety of D. lobostoma. 
Hyalosphenia papilio, Leidy. Page 131, Pl. 21. 
This handsome species is very common in the water of sphagnum 
shown on the sides of Fig. 7, Pl. 21. The outline of variety lobata 
is given in Fig. 1, which shows the extreme of constriction. Inter- 
mediate forms seem to connect this with the normal form. The 
color of the test and sarcode contents of the variety is the same as 
in the normal form. The sarcode in all the forms observed was 
encysted, and composed largely of green corpuscles. The normal
