one fourth of the total length. The foot glands are fairly large 
and pyriform. 
The corona is oblique and strongly convex without projecting 
lips. 
The mastax is small; the fulcrum is straight and slightly ex¬ 
panded posteriorly, the manubria slender and crutched. The 
gastric glands are frequently tinted red. 
The ganglion is moderately long and saccate; eyespot and retro- 
cerebral organ are absent. 
Total length 130/x; toes 32/x. 
Cephalodella collactea has been found only in Loon Lake, Vilas 
County, Wisconsin. Its nearest relative is C. intuta, from which it 
is readily distinguished by the form of the toes.

Plate XXXVI, figure 1. 
The body is moderately elongate, nearly parallel-sided and later¬ 
ally compressed. The head is short and broad, somewhat longer 
dorsally than ventrally. The neck is well marked. The abdomen 
is either parallel-sided or slightly wider posteriorly; the lorica is 
very thin and flexible and the edges of the plates indistinct; the 
lateral clefts are narrow anteriorly and increase gradually in width * 
towards the posterior end. The foot is large and very broad at 
the base; the tail is very small. The toes are long, slender, nearly 
straight, somewhat enlarged at the base and very slightly tapering, 
suddenly reduced at the ends to minute, but very distinct claws; 
their length is about one fourth of the total length. The foot glands 
are moderately large and pyriform. 
The corona is decidedly oblique and strongly convex without 
projecting lips. 
The mastax is relatively small; the posterior end of the fulcrum 
is broadly and abruptly expanded; the manubria are crutched. 
The ganglion is long and saccate; eyespot and retrocerebral 
organ are absent. 
Total length 250-270/x; toes 62-68/>i. 
Cephalodella inquilina is common among sphagnum and sub¬ 
merged plants in soft-water ponds; we have collected it in Vilas and 
Oneida Counties, Wisconsin, and around Atlantic City, New Jer-
