CILIATE FIBRILLAR SYSTEMS 195 



the rows of cilia; (2) cross fibrils, connecting adjacent longitudinal 

 fibrils; (3) opening for a trichocyst midway on the cross fibril; and (4) 

 a suture line at the anterior and the posterior poles. The resulting lattice, 

 therefore, has its counterpart in Schuberg's pattern.

each: (1) an interciliary fibril, connecting the "Basalapparaten" in each 

 longitudinal row of cilia; (2) cross fibrils, connecting the interciliary 

 fibrils; and (3) Relations korner, which include the Basalapparat and the 

 Trichocystenkorn . ' ' 

 The interciliary fibril and the Basalapparaten, therefore, find their 

 counterpart essentially in Schuberg's longitudinal fibril and its connected 

 basal granules. 



For both von Gelei and Klein, accordingly, it is evident that the 

 fibrillar system of Paramecium includes two subsystems, or fibrillar com- 

 plexes. For present convenience and especially for later discussion, I 

 shall refer to these as von Gelei's outer fibrillar complex and inner fibril- 

 lar complex and Klein's outer fibrillar complex and inner fibrillar com- 

 plex respectively.
