Harring & Myers—Rotifer Fauna of Wisconsin — 11. 493 
Cephalodella xenica was found in considerable numbers in ma¬ 
terial collected by Dr. H. S. Jennings in Huron River at Ann Ar¬ 
bor, Michigan, in 1901. Its nearest relative is C. eupoda, which 
differs in its greater size and in the absence of the eyespot, as well 
as the flexible integument. 
CEPHALODELLA NELITIS Myers, new species. 
Plate XXXII, figure 1. 
The body is elongate, very slender and somewhat prismatic. The 
head is fairly small and strongly oblique anteriorly. The neck is 
not strongly marked. The abdomen increases slightly in width 
for about two thirds of its length and from this point tapers slightly 
to the base of the foot; it is somewhat variable in width and speci¬ 
mens with parallel-sided body are occasionally met with. The lorica 
is very thin and flexible, but the plates are fairly well marked; the 
lateral clefts are rather narrow and parallel-sided for nearly their 
entire length; the extreme posterior ends are slightly flaring. The 
foot is short and conical, but broad at the base; the tail is very 
small. The toes are short, strongly decurved and very slender; 
from the slightly bulbous base they taper very gradually to acute 
points; their length is about one fifth of the total length. The foot 
glands are small and pyriform. 
The corona is oblique, strongly convex and without projecting 
lips. 
The mastax is rather small and of the normal type; the fulcrum 
is stout and slightly expanded posteriorly, the manubria rodlike, 
very slender and not crutched. The bladder is large. 
The ganglion is elongate and saccate; eyespot and retrocerebral 
organ are absent. 
Total length 135ju,; toes 22jii. 
Cephalodella nelitis was collected in a pond with soft, acid water 
among submerged sphagnum, at Gravelly Run, near Mays Landing, 
New Jersey. Its nearest relative is C. melia; a comparison is given 
under this species. 
CEPHALODELLA MELIA Myers, new species. 
Plate XXXII, figure 2. 
The body is elongate, somewhat prismatic and gibbous dorsally. 
The head is rather small, but relatively long in comparison with
