Trichoda, (hair animalcule,) an Enchelis having its mouth obliquely truncated and fur- nished with a lip; its body is unprovided with a neck-like prolongation. Lachrymaria, (lachrymatory animalcule,) (8, Jig. 11,) an Enchelis having its body destitute of cilia externally, but terminated by a long thin neck, which is clavate at the extre- mity, and ends with a mouth provided with a lip and ciliated margin. Leucophrys, (ciliated animalcule,) an En- chelis, with its body entirely covered with vibratile cilia—its mouth is obliquely terminal and provided with a kind of lip, but without dental organs. (1, jig. 12.) Holaphrya, (woolly animalcule,) an En- chelis having the exterior of its body entirely ciliated. Prorodon (toothed rolling animalcule). In this genus, like the last, the body is covered all over with vibratile cilia, and the mouth Fig. and posteriorly terminates in three or five little sharp points. The next family, Trachelinida, contains all those non-loricated animalcules whose alimen- tary canal has two distinct orifices, but of which one only, the anal, is terminal. The genera that belong to it are very interesting objects, and many of them of great beauty. The reader Fig. 13. 1. Leucophrys patula. 2.

(\fiS- 12 ) The family Colepinidae consists of but one genus, Coleps (1, 2, Jig. 13), the animalcules belonging to which have all the characters of Enchelis, except that they are loricated. These a
