lateral clefts are fairly wide at the ends and slightly narrower at 
mid-length. The foot is short and stout; the tail is fairly promi¬ 
nent and near the posterior end. The toes are very long and 
wide apart at the base, fairly stout and tapering for about 
one fifth of their length; from this point they are very nearly 
cylindric and end in acute, conical tips, the dorsal edge straight 
and the ventral bending abruptly upwards to meet it. The length 
of the toes is about one third of the total length. The foot glands 
are small and pyriform. 
The corona is strongly oblique and distinctly convex without 
projecting lips. 
The mastax is large and of the normal type; the fulcrum is 
moderately long and slightly expanded at the posterior end; the 
manubria are slender, rodshaped, slightly clubbed and decurved 
posteriorly, but not crutched. The gastric glands are small and 
ovate. 
The ganglion is long and saccate; the eyespot is very lafge and 
saucer-shaped and at the posterior end of the ganglion. The retro- 
cerebral organ is absent. 
Total length 145-150/x; toes 50-54/a. 
Cephalodella dorseyi is not very common. We have collected 
it among submerged sphagnum and other plants in soft, acid water 
ponds around Atlantic City, New Jersey. It is readily recog¬ 
nized by the long, very slender toes with their peculiar, clawlike 
points.

Plate XXX, figure 3. 
The body is elongate, slender, slightly curved and laterally com¬ 
pressed. The head is relatively small and short and distinctly de- 
flexed. The neck is not strongly marked. The abdomen is nearly 
parallel-sided, very slightly gibbous dorsally and concave ven- 
trally; the lorica is firm and the plates well marked. The lateral 
clefts are narrow anteriorly and increase slightly in width to¬ 
wards the posterior end. The foot is fairly long and stout; the 
small tail is near the posterior end. The toes are long, slender 
and slightly recurved, moderately stout at the base and taper grad¬ 
ually to extremely slender, acute points; their length is a little 
less than one third of the total length. The foot glands are rather 
small and pyriform.
