A cylindric enchelis, the fore-part truncated.
This is one of the most transparent animalcula; the hinder-part of an obtuse convexity, the fore-part truncated. Müller suspects that there is a rotatory organ in the fore-part. No intestines can be seen. It runs backwards and forwards through the drop in a diametrical line, with a wavering motion; sometimes turns round for a moment, but presently enters on its usual course. Is found in an infusion of grass and hay.
40. Enchelis Caudata.
E. elongata, antice obtusa, postice in caudam hyalinam attenuata, [Plate XXV.] Fig. 9. Enchelis with a long body, the fore-part obtuse, the hinder-part diminishing into a kind of tail.
The body is of a grey colour, pellucid, with globular molecules divided from each other, and dispersed through the whole body; the fore-part a, thick and obtuse, the hind-part b, crystalline and small, the end truncated. It is but seldom met with.
41. Enchelis Epistomium.
E. cylindrico-elongata, apice gracili subgloboso. Enchelis with a long cylindric body, the fore-part slender and roundish.
It is among the smaller animalcula, the body is cylindrical and bright, the hinder-part obtuse, the fore-part smaller, and terminating in a globule; a black line may now and then be perceived down the middle of it.
42. Enchelis Gemmata.
E. cylindracea, serie globulorum duplici, in collum hyalinum producta. Enchelis with a cylindrical body, the upper part prolonged into a transparent neck, a double series of globules running down the body. Its motion is slow, and generally in a straight line; it is found in ditch-water where the lemna thrives.
