boscis a row of long cilia with trichocysts. Mouth a long 

 slit, upon left side at base of proboscis, commonly not 

 visible. Usually two nuclei and a contractile vacuole at 

 beginning of the tail, near the dorsally opening anus.

Fig. 133 represents a form which I have provisionally 

 placed with this genus. 

 New Genus (?). 



Body elongated and uniformly ciliate, with a proboscis 

 resembling Lionotus. The mouth, however, is terminal, 

 and leads into a pharynx armed with rods. Nucleus 

 double, and several contractile vacuoles. 



F^g- 159- Only a single specimen of this peculiar 

 form has been found. 

 Loxodes Ehrbg. 



Inflexible, flattened, elongated, and leaf-like, the an- 

 terior end hook-like and bent to left. Ventral surface 

 flat, with ciliated ribs, dorsal surface smooth, curved, 

 and without cilia. The edge of the body with somewhat 

 longer cilia. Mouth on the left anterior edge, at the bot- 

 tom of a slit-like peristome and leading into an evident 

 pharynx. Many nuclei and secondary nuclei. Contrac- 

 tile vacuoles uncertain. 

 Lox. rostrum Miill., Fig. 154. 

 Chilodon Ehrbg. 



Much compressed, with a flat or slightly hollowed ven- 

 tral surface, and a convex dorsal surface. A thin, flexible 

 hyaline border prolonged in front into a projection di- 

 rected forward and to the left. Mouth in the middle of 

 the body, with a basket-like pharynx of ten to sixteen 

 rods ; its inner end frequently spirally rolled. Ventral 

 surface regularly striated and ciliated. Dorsal surface 

 without cilia. A band of stronger cilia extending from 

 the mouth to the end of the elongated projection. Nu- 

 cleus ellipsoidal, of peculiar structure. One or more con- 

 tractile vacuoles.
