CEPHALODELLA APOCOLEA Myers, new species. 
Plate XXXIII, figures 1-2. 
The body is moderately elongate, nearly cylindric and slightly 
compressed laterally. The head is large and relatively short. The 
neck is not strongly marked. The abdomen is nearly parallel¬ 
sided and slightly convex dorsally; the lorica is very thin and 
flexible, but the plates are well marked; the lateral clefts are 
moderately wide and parallel-sided. The foot is large and robust; 
the small tail is near the posterior end. The toes are extremely 
far apart at the base, cylindric and straight for about two thirds 
of their length, abruptly recurved and ending in slender, sickle¬ 
shaped, acute points; their length is about one fourth of the total 
length. The foot glands are very large and pyriform. 
The corona is oblique, moderately convex and without projecting 
lips. 
The mast ax is large and of the normal type, but the trophi are 
slender; the fulcrum is slightly incurved at the extreme end, 
but not expanded; the manubria are delicate, slightly curved rods, 
and not crutched. The gastric glands are small. 
The ganglion is moderately elongate and pyriform; eyespot and 
retrocerebral organ are absent. 
Total length 125-135/x; toes 32-35/x. 
Cephalodella apocolea is common in weedy ponds and bogs; 
we have collected it in Vilas and Oneida Counties, Wisconsin; 
around Washington, District of Columbia; Atlantic and Ocean 
counties. New Jersey, and Polk County, Florida; also in material 
collected by Dr. H. S. Jennings around Ann Arbor, Michigan.

The body is elongate, fairly slender, slightly gibbous dorsally 
and faintly curved. The head is relatively long and tapers very 
slightly from the neck towards the corona; it is protected by a dis¬ 
tinct lorica, which falls into definite folds when the head is re¬ 
tracted, as in the genus Diurella and others. The neck is well 
marked. The abdomen is somewhat prismatic and slightly arched 
dorsally; its greatest depth is near mid-length. The plates of the
