Loxodes DuJARD., not EHRENB. [young individuals of Chilodon 
cucullulus with imperfectly developed infundibulum. Srein. Jnfus. 
p- 131.] 
Ervilia Dusarp. (Species from the genus Huplotes HHRENB.) 
Trochilia DusarD. 
Family XIII. Vorticellina ( Vorticellina and Ophrydina EHRENB.) 
Body campanulate or infundibuliform, with large vibratile cilia at 
the margin of the aperture. Mouth and anus approximate, situated 
in a pit of the margin. 
Formerly these animals were classed amongst the Polyps as Bell- 
Polyps, Bastard-Polyps, &c. (See the first Dutch edition of this 
Handbook, 1. p. 66.) It was believed that the infundibular or bell- 
shaped body is the cecal stomach, and the large opening the 
mouth. The true oral aperture, however, is placed on the edge of 
the hollowed body. The food describes a circle in the parenchyme 
(according to EHRENBERG in a special intestinal canal’ with several 
lateral dilatations) and is again ejected near the oral aperture (hence 
the names cyclocela and anopisthia given by ExRENBERG). ‘The 
analogy with the molluscan type, even if an intestinal canal be not 
admitted, cannot be overlooked, and probably these animals will be 
ranked by future writers, as imperfect forms, with the Bryozoa. 
The cilia on the edge of the bell-shaped body cause in the water 
an eddy which hurries onwards minute corpucles whether dead or 
alive, and conveys them towards the cavity. If some early and 
also later observers (amongst others even AGARDH, Nov. Act. Acad. 
Cesar. Leop. Carol. Natur. Curiosor. x. 1821, pp. 127—137, Tab. vn. 
ii.) have seen in this a power of fascination, the fact must be ascribed 
to the circumstance, that they did not notice the cilia. 
Phalanx I. Body not pedunculated. 
A. Naked. 
Stentor OKEN, Enrens. (Species of Vorticella MUuELL.) 
Body conical, from its contractility polymorphous, everywhere 
1 See Foxke’s observations on Stentor, which led him to doubt so early the exist- 
ence of a special intestinal canal. Oxurn’s Jsis, 1836. 8. 785, 7806.
