back on the foot. The toes are long, slender, wide apart at the base, 
double-curved and taper gradually to acute, bristle-like points; 
their length is about one third of the total length. The foot glands J 
are small and pyriform. ^ 
The corona is strongly oblique and convex with prominent, beak- 1 
like lips. I 
The mastax is very large and of the normal type; the fulcrum is ^ 
slightly expanded at the posterior end; the manubria are slender, ; 
slightly clubbed and recurved at the ends, but not crutched. The 
gastric glands are small. 
The ganglion is very long and somewhat pyriform; the eyespot 
is at the posterior end. No retrocerebral organ is present. 
Total length 105-110 /a; toes 35-40/x. 
Cephalodella nana has been collected only in sphagnum along the 
marshy edges of Corduroy Creek, near Absecon, New Jersey. It 
resembles C. cuneata, but the presence of an eyespot and the sig¬ 
moid curvature of the toes is sufficient to distinguish it.

The body is moderately elongate and gibbous dorsally. The head 
is large and oblique anteriorly. The neck is marked by a rather 
shallow constriction. The abdomen is arched dorsally, its greatest 
depth near mid-length; the lorica is fairly rigid and the plates well 
marked; the lateral clefts are wide and parallel-sided. The foot is 
large and robust; the prominent tail is near the posterior end. The 
toes are short, blade-shaped and very broad; they increase slightly 
in width for about half their length, then decrease rather suddenly 
to very slender, conical tips, slightly blunted at the extreme ends; 
their length is less than one fifth of the total length. The foot 
glands are rather small and ovate. 
The corona is oblique and strongly convex without projecting 
lips. 
The mastax is fairly large and of the normal type; the fulcrum 
is very slightly expanded at the posterior end; the manubria are 
long and have a very pronounced terminal crutch. The gastric 
glands are small and oval. 
The ganglion is elongate and pyriform; no retrocerebral organ 
is present. The eyespot is at the posterior end of the ganglion. 
Total length 128/1; toes 22/i.
