E. obovata, crystallina, medio coarctata. Sub-oval enchelis, crystalline, with a stricture in the middle.

37. Enchelis Pulvisculus.
E. elliptica, interaneorum congerie viridi. Of an elliptic shape, with a congeries of green intestines.
It is a round animalculum, pellucid, the fore-part obtuse, the hind-part rather sharp, marked with green spots; myriads may sometimes be seen wandering about in one drop; it is found among the green matter on the sides of the vessels in which water has been kept for some time.
38. Enchelis Fusus.
E. cylindracea, utraque extremitate angustiore truncata. Cylindrical enchelis, both ends truncated.
The body is round and transparent, the fore and hind-part smaller than the rest of the body, and equally so, the ends a little truncated. In the inside a long and somewhat winding intestine, a sky-coloured bright fluid, and some black molecules transversely situated, may be discerned. The motions of this animalculum are languid; it was found in pure water.
