Florida. It bears a striking resemblance to C. gibha, from which 
it differs in the much smaller size, cervical eyespot, acutely pointed 
toes and the form of the trophi. 
CEPHALODELLA COMPEESSA Myers, new species. 
Plate XXX, figure 1. 
The body is moderately elongate, slightly gibbous dorsally and 
strongly compressed laterally. The head is rather small and dis¬ 
tinctly deflexed. The neck is well marked. The abdomen increases 
gradually in width towards the posterior end. The lorica is fairly 
rigid and the plates distinct; the lateral clefts are narrow an¬ 
teriorly and increase gradually in width towards the posterior end. 
The foot is broad at the base and fairly stout. The toes are long, 
slender and cylindric for about two thirds of their length; the 
posterior third tapers gradually to very acute points; the dorsal 
edge is straight throughout and the ventral bends upwards to meet 
it. The length of the toes is about one third of the total length. 
The corona is oblique and distinctly convex without projecting 
lips. 
The mastax is large and of the normal type; the fulcrum is long, 
stout and slightly expanded at the posterior end; the manubria 
are very slender, rodlike and strongly recurved posteriorly. The 
gastric glands are small and irregularly ovate. 
The ganglion is long and saccate; the eyespot is at the posterior 
end, well towards the ventral side. The retrocerebral organ is 
absent. 
Total length 140-145/>t; toes 45-48/a. 
Cephalodella compressa is common in sphagnum and among sub¬ 
merged plants in soft, acid water ponds and bogs in Vilas and 
Oneida Counties, Wisconsin, and around Atlantic City, New Jer¬ 
sey. It is readily recognized by the strongly compressed body. 
CEPHALODELLA DORSEYI Myers, new species. 
Plate XXX, figure 7. 
The body is relatively short, stout and slightly gibbous dorsally. 
The head is large, slightly deflexed and strongly oblique ante¬ 
riorly. The neck is well marked. The abdomen increases grad¬ 
ually in width for about two thirds of its length and is gently 
rounded posteriorly; the lorica is firm and the plates distinct; the
