C. ovale, postice acuminatum. An oval cyclidium, the hind-part pointed.
The body is pellucid, depressed, the fore-part obtusely convex, the hind-part acute, the intestines vesicular, the fore and hind-part on each side dark. It resembles a grape-seed.
90. Cyclidium Hyalinum.
C. ovatum, postice acutum. Oval cyclidium, the hind-part acute.
This cyclidium is oval, flat, and bright, without any visible intestines, the hinder-part somewhat smaller than the fore-part; it has a tremulous kind of motion.
91. Cyclidium Pediculus.
C. ovale convexum, subtus planum. An oval convex cyclidium, the bottom even. Trembley Polyp. 1, p. 282.
This is a gelatinous white animalculum, the bottom gibbous over the back, the extremities depressed and truncated, with one end sometimes apparently cloven into two; perhaps this is the aperture of the mouth. It is scarce ever seen but on the arms and the body of the hydra pallida, upon which it runs as if it had feet.
92. Cyclidium Dubium.
C. ovale, supra convexum, subtus cavum. Oval cyclidium, the upper part convex, the under part concave.
