Earring Myers—Rotifer Fauna of Wisconsin — II. 429 
forcipate Notommatids. The neck segment is fairly long and 
nearly as wide as the body at its widest point. The anterior trans¬ 
verse folds are well marked. The abdomen is very nearly parallel¬ 
sided and ends in a slightly projecting tad, under which the cloaca 
opens. The foot is very stout, but little smaller in diameter than 
the abdomen; the anterior joint is twice as long as the nearly 
hemispherical posterior joint. The toes are minute, slender and 
conical, set wide apart, and freely movable, so that the-ir tips may 
be brought into actual contact in the manner of a pair of forceps. 
The dorsal antenna is a small setigerous papilla in the normal 
position; the lateral antennae have not been found. 
The corona is obliquely ventral and weakly ciliated with the ex¬ 
ception of the two frontal, auricle-like areas, which are furnished 
with strong cilia adapted to swimming. The mouth is at the 
posterior margin of the corona. The rostrum is outside of the 
corona, as the circumapical band has disappeared. 
The mastax is very nearly identical wdh that of Proales 
decipiens^ and consequently no figure is given. The incus is al¬ 
most straight; the fulcrum is slightly tapering from the base to¬ 
wards the ventral end. The rami are triangular and have a large 
basal apophysis; the inner edges are obscurely dentate. The manu- 
bria are elongate, rod-shaped, and expanded anteriorly into broad 
plates; the unci have each five well-developed teeth. An epi- 
pharynx has not been found, but may be present; on account of the 
very small size it is difficult to make out the true form of the vari¬ 
ous elements of the mastax. 
The oesophagus is very long and slender. The gastric glands, 
ovary and bladder are normal. The stomach and intestine are not 
separated by a constriction. The foot glands are pyriform and 
rather small. 
The ganglion is large and saccate. A retrocerebral sac is pres¬ 
ent, but there are no sub cerebral glands; the sac is partly fused to 
the ganglion and apparently ductless. No eyespot has been found. 
Total length 90-120ja; toes 5-7jn, distance apart 7~8/x; trophi 12/x. 
A few specimens of this species have been found in sphagnum 
growing on the banks of ditches at G-len Burnie, Maryland; Mr. 
David Bryce has found it in sphagum collected in Otsego county. 
New York, by Mrs. A. C. Clarke, and sent to him. It is Mosely re¬ 
lated to Proales decipiens, but is easily distinguished by its peculiar 
toes, smaller size and more slender body.
