Harring & Myers—Rotifer Fauna of Wisconsin — II. 485 
are blade-shaped, decurved and acutely pointed; the dorsal edge 
is evenly curved and the ventral edge has a blunt cusp about one 
third of its length from the base; the length of the toes is one 
fourth of the total length. 
The corona is strongly oblique and the lips project as a small 
beak. 
The mastax is large and the trophi of normal type; the fulcrum 
is slightly expanded posteriorly and the manubria rodlike, not 
crutched. 
The ganglion is very large and saccate; the eyespot is at the 
posterior end. There is no retrocerebral organ. 
Total length 150-160ju,; toes 35-40/i; trophi 45ja. 
Cephalodella physalis is not rare among sphagnum and sub¬ 
merged plants in soft-water ponds around Atlantic City, New 
Jersey. It resembles C. Upara, but the body is not as stout; the 
much longer toes and the presence of an eyespot are sufficient to 
separate it from this species. 
CEPHALODELLA STEIGOSA Myers, new species. 
Plate XXIX, figure 7. 
The body is moderately elongate, nearly eylindric and slightly 
gibbous dorsally. The head is relatively long and strongly oblique 
anteriorly. The neck is marked by a shallow constriction. The 
abdomen increases very slightly and gradually in width for about 
three fourths of its length; from this point the dorsal edge curves 
downward to the base of the foot. The integument is very flexible 
and the plates ill-defined; the lateral clefts are somewhat obscure, 
apparently narrow and parallel-sided throughout their length. 
The foot is short and broadly conical; the tail is a small, rounded 
boss near mid-length. The toes are very long, slender, slightly de¬ 
curved and taper gradually to extremely acute, needle-like points; 
their length is about one fourth of the total length. The foot 
glands are rather small and pyriform. 
The corona is strongly oblique, decidedly convex and without 
projecting lips. 
The mastax is fairly large and of the normal type; the fulcrum 
is slightly expanded posteriorly, the manubria very slender and 
not crutched. The gastric glands are small and rounded.
