Earring & Myers—Rotifer Fauna of Wisconsin — II. 501 
tail is small and rounded. The lorica is fairly rigid and the plates 
well marked. The lateral clefts are narrow anteriorly and increas 
gradually in width towards the posterior end of the lorica. The 
toes are faintly recurved, wide apart at the base, very long and 
slender, tapering slightly to acute, clawlike points with transverse 
basal septa; their length is about one fourth of the total length. 
The corona is convex and strongly oblique, without projecting 
lips. 
The mastax is large and of the normal type; the fulcrum is 
broadly expanded at the posterior end and the manubria crutched. 
The gastric glands are tinted red. 
The ganglion is long and saccate; at its posterior end is a small 
sac with well marked duct, bifurcate at the anterior end, but not 
reaching the surface of the corona. There is no eyespot. 
Total length 115-125/x ; toes 30-35/x ; trophi 40/x. 
Cephalodella intuta has been collected among submerged sphag¬ 
num and other aquatic vegetation in Loon Lake, about one mile 
south of Eagle Eiver, Vilas County, Wisconsin, and in soft, acid 
water ponds around Atlantic City, New Jersey. Its nearest rela¬ 
tive is C. forficata, from which it differs in the form of the body, 
shorter foot and much longer and more slender toes, as well as in 
its smaller size. 
CEPHALODELLA COLLACTEA Myers, new species. 
Plate XXXIV, figure 5. 
The body is moderately elongate, nearly cylindrical and slightly 
gibbous dorsally. The head is very short and strongly oblique 
anteriorly. The neck is well marked. The abdomen increases 
gradually in width for nearly three fourths of its length and from 
this point tapers rapidly to the large, robust foot; the tail is a 
small rounded boss. The lorica is fairly rigid and the plates well 
marked; the lateral clefts are narrow anteriorly and increase grad¬ 
ually in width towards the posterior end. The toes are long, 
straight, slender and very slightly tapering; the dorsal edge is 
straight throughout; the ventral edge is straight for about five 
sixths of the length of the toe; at this point it bends abruptly at 
an obtuse angle to meet the dorsal line and this tapering portion 
of the toe ends in a bristle-like point. The length of the toes is
