liarring Myers—Rotifer Fauna of Wisconsin — II, 433 
is followed by three linear teeth of nearly equal length; the basal 
plate is subsquare. The right uncus has a large ventral, clubbed 
tooth, followed by a much more slender, minutely clubbed tooth 
and three linear teeth; the basal plate is sub-triangular. The 
manubria are very long and strongly curved posteriorly, so that 
the ends are directed inwards and towards the dorsal side of the 
mastax; the two lateral cells are small, so that three fourths of the 
entire length of the manubrium belongs to the central cell only. 
The epipharynx consists of two thin, curved plates, imbedded in 
the walls of the mastax at the sides of the mouth. There are indi¬ 
cations of the presence of a rudimentary piston, attached to the 
ventral wall of the mastax, but not to the fulcrum. 
The oesophagus is moderately long and slender. The stomach 
and intestine are not separated by a constriction. The gastric 
glands, ovary and bladder are normal. The foot glands are ex¬ 
cessively long, the gland itself being within the body and the duct 
as long as the foot. 
The ganglion is moderately large and saccate. The eyespot is 
near the anterior margin; it is double, composed of two triangular 
pigment cells. No retrocerebral organ is present. 
Total length 250-300/x; toes 20-25/x; trophi 32/x. 
Proales reinhardti is not rare in brackish tidepools; we have 
collected it near Atlantic City, New Jersey. It seems to occur also 
in fresh water, according to Voigt, Lauterborn, Murray, Yon 
Hofsten, Sachse and Hauer. 
It may be questioned whether Furcularia gammari Plate should 
be considered a synonym of this species; with the exception of the 
length of the foot there is complete agreement in everything else, 
and, as the foot of Proales reinhardti is highly contractile, it is not 
unlikely that Plate may have had a specimen of this species before 
him. 
According to Yon Hofsten Distyla weissei Eichwald is ‘‘un¬ 
doubtedly’’ a synonym of P. reinhardti; we are unable to see a 
single character in Eichwald’s description or figures that belongs 
unmistakably to this species and the extrapolation required is far 
too great to make it advisable to displace the generic name Proales 
by Distyla. If a guessing contest is to be admitted, Endesma 
Ehrenberg has a far better claim to consideration, but many nat¬ 
uralists will question the wisdom of assigning to any animal char-
