Harring & Myers—Rotifer Fauna of Wisconsin — II. 499 
is nearly half as long as the abdomen and very stout; the tail is 
small and somewhat beyond mid-length. The toes are short and 
taper very slightly for one half of their length, changing abruptly 
to conical, acute points; their length is a little less than one fifth of 
the total length. The foot glands are very small and pyriform. 
The corona is oblique, slightly convex and without projecting 
lips. 
The mastax is rather small and of the normal type; the fulcrum 
is very slightly expanded posteriorly, the manubria very slender 
and not crutched. The gastric glands are very small. 
The ganglion is moderately elongate and pyriform; eyespot and 
rectrocerebral organ are absent. 
Total length 160/x; toes 30/x. 
Cephalodella dixon-nuttalli is known only from Lake Kathan, 
Oneida County, Wisconsin; it was collected among submerged 
sphagnum and other small aquatic plants. All the specimens seen 
had the toes closely appressed, producing the appearance of a single 
toe.
