sey. It is a very rapid swimmer, readily recognized by its large 
size and the peculiar, clawed toes. 
CEPHALODELLA LICINIA Myers, new species. 
Plate XXXIV, figure 4. 
The body is elongate, slender and somewhat prismatic. The 
head is a little longer than wide and obliquely truncate anteriorly. 
The neck is not strongly marked. The abdomen is very slightly 
arched dorsally, almost parallel-sided; the lorica is fairly rigid 
and the plates well marked; the lateral clefts are rather narrow 
anteriorly and increase in width towards the posterior end. The 
foot is conical and moderately large; the tail is small and rounded 
and unusually far back on the foot. The toes are long and slender; 
they are nearly parallel-sided and straight for about three fourths 
of their length; the terminal portion is strongly decurved and 
tapers to very slender, bristle-like points; their length is about one 
fourth of the total length. The foot glands are small and pyri¬ 
form. 
The corona is oblique and slightly convex without projecting 
lips. 
The mastax is relatively small and weak; the fulcrum is slightly 
expanded at the posterior end and the manubria are slender, rod¬ 
like and not crutched. The gastric glands are small. 
The ganglion is very long and saccate. The eyespot and retro- 
cerebral organ are absent. 
Total length 105/>t; toes 28^. 
Cephalodella licinia is found in small numbers among Fontinalis 
novae-angliae in bog pools at Bargaintown, near Atlantic City, 
New Jersey. 
CEPHALODELLA VACUNA Myers, new species. 
Plate XXXV, figure 6. 
The body is elongate, fairly slender, nearly parallel-sided and 
somewhat prismatic. The head is long and obliquely truncate 
anteriorly. The neck is well marked. The abdomen increases 
very slightly in size towards the posterior end and is faintly curved 
dorsally; the lorica is flexible and the plates well marked; the 
lateral clefts are fairly wide anteriorly and become more so towards 
the posterior end. The body is obliquely truncate posteriorly; the
