Harring & Myers—Rotifer Fauna of Wisconsin — II. 489 
The corona is oblique and strongly convex without projecting 
lips. 
The mastax is small and of the normal type; the fulcrum is 
very slightly expanded posteriorly and the manubria distinctly 
crutched. The gastric glands are small and somewhat triangular. 
The ganglion is long and saccate; the small eyespot is at the 
posterior end, on the dorsal side. No retrocerebral sac is present. 
Total length 130-135/x; toes 38-40)U. 
Cephalodella hiulca is not rare in soft, acid water ponds among 
Fontinalis, Riccia and sphagnum; we have collected it at Bargain- 
town and Oceanville, New Jersey. It resembles superficially 
0. strepta, but is much larger and without the head sheath of this 
species; an additional distinction is the presence of an eyespot in 
C. hiulca. 
CEPHALODELLA ELEGANS Myers, new species. 
Plate XXXI, figure 8. 
The body is elongate, very slender, somewhat curved and slightly 
compressed dorso-ventrally. The head is relatively large and very 
slightly defiexed. The neck is not very strongly marked. The 
abdomen is slightly curved dorsally and nearly straight ventrally; 
the lorica is firm and the plates distinct. The lateral clefts are 
narrow anteriorly and increase gradually and considerably in 
width towards the posterior end. The foot is small and terminates 
in a short, cylindric section; the tail is very minute and only a 
short distance beyond the lorica. The toes are very long and 
slightly decurved, fairly stout at the base and tapering rapidly 
to slender, nearly cylindric, acutely pointed rods; their length is 
about one third of the total length. The foot glands are rather 
small and pyriform. 
The corona is slightly oblique and moderately convex without 
projecting lips. 
The mastax is small and of the normal type; the fulcrum is 
slightly expanded at the posterior end and the manubria are dis¬ 
tinctly recurved and increase somewhat in width towards the ends. 
The gastric glands are small and oval. 
The ganglion is long and pyriform; the eyespot is fairly large 
and at the posterior end of the ganglion; no retrocerebral organ 
is present. 
Total length 135-140/x; toes 48-50/x.
