Cilia. — The length of the cilia also varies in different individuals. 
Fig. 7 shows an instance in which they are remarkably long. Fig. 3 
one in which they are of normal length. 
Cuticle. — The cuticle was thick enough to present a very distinctly 
double-contoured appearance, shown in all the figures. 
Pharynx and Anus. — The pharynx is shown in section in plate IX. 
figs. 4, 6, 8, slightly in fig. 3. The anus and contractile vacuole are 
seen in fig. 4. 
Karyojohores. — The protoplasmic bands, thus named by Schuberg 
(7), which appear to sling the. macronucleus in position, are seen in 
position in most of the drawings ; specially in figs. 3 and 6. 
In conclusion, I must offer my best thanks to Mr. E. A. Minchin, 
Fellow of Merton College, Oxford, for his kindness in criticising these 
notes, and for much valuable assistance ; to him are due such references 
as I have been able to give to the literature of the subject.
