 fusorian. 



CILIA ^Lat. cilium, an eye-lash). Microscopic, hair-like filaments, which

 Ctcnophora, an order of Actinozoa.

 Barnacles and Acorn-shells (Cirripedes), the lateral processes on the 

 arms of Srachiopoda, &c.

 sarcode, enclosed in a delicate calcareous envelope, and bearing coccoliths 

 upon their external surface. Both coccospheres and coccoliths are im-

 low Bhizopodic organism. 



COCOON (French cocon, the cocoon of the silk-worm ; connected with Fr. 

 coque, shell, which is derived from the Lat. concha). The outer covering
