This species may be distinguished from other members of the 
genus by the general form, as well as by the robust, acutely 
pointed toes.

The body of this species is elongate, spindle-shaped, and slender, 
the greatest width being only one fifth of the total length. The 
integument is leathery and the form fairly constant. The color 
of the entire animal is a light orange-brown. 
The head segment is short and strongly rounded in front, al¬ 
most semicircular; the neck segment is as long as the greatest 
width of the body and considerably narrower. The anterior trans¬ 
verse folds are well marked. The abdomen is nearly cylindric 
for two thirds of its length, the posterior third tapering gradu- 
ually to the toes; there is no true foot. Over the cloaca there is 
a rounded hump with the outline of a tail on its posterior end. 
The toes are very short, broadly conical, and somewhat compressed 
laterally; they are not sclerified, as in the case of the great ma¬ 
jority of rotifers, but are very soft and may be completely in¬ 
verted and withdrawn within the body under the action of the 
longitudinal muscles. 
The dorsal antenna is in the normal position; the lateral an¬ 
tennae are somewhat farther back than usual. 
The corona extends down on the ventral side about one fourth 
of the length of the body; the post-oral portion projects as a chin. 
The rostrum or cuticular fold immediately above the mouth is 
well marked. No auricles are present; two slight antero-lateral 
depressions are somewhat more strongly ciliate that the rest of 
the corona. The very long, pendant, bottle-shaped cells of the 
corona are conspicuous. 
The mastax differs only in minor details from the typical form 
of the genus. The rami are broadly lyrate with very large alu¬ 
lae and a short, nearly right-angled dorsal extension, on which 
the unci rest. The fulcrum is of nearly the same length as the 
rami, rather slender, and tapers to a blunt point. The unci con¬ 
sist of two parts, firmly united to each other but not integral; a
