foot is large and conical, projecting slightly beyond the small, 
rounded tail. The toes are very long, faintly recurved and slender, 
tapering gradually to acute points; their length is more than one 
fourth of the total length. The foot glands are small. 
The corona is convex and strongly oblique without projecting 
lips. 
The mastax is large and of the normal type; the fulcrum is 
slightly expanded posteriorly and the manubria strongly crutched. 
The ganglion is large and elongate saccate. Neither eyespot 
nor retrocerebral organ are present. 
Total length 220/x ; toes 62/x. 
Cephalodella vacuna has been collected in small numbers among 
submerged sphagnum in a pond with soft, acid water at Gravelly 
Run, near Atlantic City, New Jersey. 
CEPHALODELLA SPECIOSA Myers, new species. 
Plate XXXIV, figure 6. 
The body is moderately elongate and tapers gradually to the 
base of the toes. The head is very large; its dorso-ventral width 
is greater than the width of the abdomen. The neck is well marked. 
The abdomen tapers rapidly from the neck to the base of the foot; 
the plates of the lorica are moderately flexible and separated by 
well marked lateral clefts. The foot is of normal length; the tail 
is small and knoblike and does not quite reach the posterior end 
of the foot. The toes are very long, slender, tapering and very 
slightly decurved; near the blunt tip is a transverse septum, giving 
the toes an appearance of being clawed; their length is but little 
less than half the length of the body. 
The corona is oblique and without projecting lips. 
The mastax is large and of normal type; the fulcrum is crutched 
and the manubria slender and rodlike. 
The ganglion is large and saccate; neither eyespot nor retrocere¬ 
bral organ are present. 
Total length 145-155/a; toes 45-47/x. 
Cephalodella speciosa is found in a large pond at Oceanville, New 
Jersey, among Biccia and floating sphagnum in soft, acid water.
