Earring & Myers—Rotifer Fauna of Wisconsin — II. 471 
Cephalodella innesi has been collected around Atlantic City, 
New Jersey, in weedy ponds with soft, acid water. It is readily 
distinguished by the small head and gibbous body and also by its 
rapid, restless mode of swimming. 
CEPHALODELLA MINERI Myers, new species. 
Plate XXVI, figure 1. 
The body is rather short and nearly cylindric, slightly gibbous 
dorsally. The head is moderately large and somewhat deflexed. 
The neck is not very distinctly marked. The abdomen is nearly 
parallel-sided, slightly convex dorsally; the lorica is very thin and 
flexible, but the plates are fairly well defined; the lateral clefts 
are very narrow and parallel-sided, slightly flaring at the extreme 
posterior end. The foot is relatively short, conical and robust; 
the very small tail is a little beyond mid-length. The toes are 
short, strongly decurved, extremely broad at the base and taper 
gradually and regularly to acute points; their length is about one 
fifth of the total length. The foot glands are large and ovate. 
The corona is slightly oblique and convex without projecting lips. 
The mastax is fairly large and of the typical form; the fulcrum 
is rather stout and slightly expanded posteriorly, the manubria 
long, very slender and crutched. The gastric glands are small. 
The ganglion is elongate and saccate; the eyespot is double 
and frontal, the two pigment spheres fairly wide apart, and the 
retrocerebral organ absent. 
Total length 125/a; toes 27/a. 
Cephalodella mineri is very abundant among Fontinalis nova- 
angliae in a brackish stream near Tuckahoe, Atlantic County, 
New Jersey. 
CEPHALODELLA ELONGATA Myers, new species. 
Plate XXVI, figure 2. 
The body is elongate, cylindric and extremely slender. The head 
is unusually long and convex anteriorly. The neck is indistinct. 
The abdomen is cylindric throughout its length; the lorica is very 
thin and flexible and the plates ill-defined; the lateral clefts are 
very obscure, but apparently very narrow and parallel-sided. The 
foot is short and conical; the small tail is near the posterior end. 
The toes are short, slightly decurved, and taper gradually and
